[Source: Saab] PRESS RELEASE: Saab 9-7X Aero Takes Off
Limited Edition SUV Offers Jet-Like Performance
DETROIT -- Saab takes SUV-performance to a new altitude as it announces the Aero performance version of the Saab 9-7X today. The limited edition 9-7X Aero will make its way to dealer showrooms early this autumn.
The Saab 9-7X brings unique Saab brand characteristics to the midsize SUV segment, including sophisticated styling inside and out, premium design features, and the sporty and spirited performance inherent to Saab vehicles. Since its debut two years ago, more than 12,000 have been sold in the U.S. and Canada. For 2008, Saab adds the Aero model - the symbol of serious Saab performance - to the 9-7X lineup. The limited edition 9-7X Aero takes Saab's interpretation on the midsize SUV to an entirely new level accelerating the performance aspect of the sophisticated vehicle with a 6.0L V-8, 20-inch wheels and tires, unique paint and custom interior accouterments.
"The 9-7X Aero is one great SUV to pilot," Shannon said. "We are excited to offer enthusiastic drivers an increased level of performance with the Aero, a symbol of Saab performance, in the midsize SUV segment."
The new 9-7X Aero features a powerful, 6.0L small-block V-8 delivering 390 horsepower (295 kW) and 395 lb.-ft. (542 Nm) of torque. With 0-60 mph acceleration under six seconds, the 9-7X Aero is a treat for those who are actively passionate about the driving experience.
The 9-7X Aero will be easy to spot as it wears a paint color all its own: Carbon Flash Metallic. The charcoal metallic paint nicely enhances the SUV's clean lines. Specific to the 9-7X Aero are 20-inch polished, aluminum wheels wrapped with P255/50R20 V-speed-rated performance tires that provide the optimum balance between ride and handling. Complementing the refined and driver-oriented cockpit-inspired interior are "Aero" embroidered leather seats and embossed floor mats.
Under the hood of the 9-7X Aero is the LS2 6.0L V-8 with a cold air induction package, rated at 390 horsepower (295 kW)* at 6,000 rpm and 395 lb.-ft. of torque (542 Nm)* at 4,000 rpm. The LS2 6.0L is based on the small-block V-8 architecture and delivers excellent down-low torque for strong off-the-line performance. Torque is inherent to the engine's cam-in-block design, which features large 4.00-inch-diameter (101,6 mm) bores and a 3.62-inch (92 mm) stroke. Response is crisp and immediate, thanks to the electronically controlled throttle.
Unique to the 9-7X Aero's version of the engine is a composite intake manifold adapted to the LS2 engine to help produce balanced torque and horsepower. Maximum towing capacity on 9-7X Aero model is 6,600 pounds (2994 kg).
Like all Saabs, the new Saab 9-7X Aero is driver-focused, with a lowered chassis tuned and tested to deliver responsive, balanced handling. Corner control and body roll control are improved with front stabilizer bars that are approximately 10 percent larger in diameter. Additional strength is provided by a heavy-duty rear axle with limited-slip differential.
With a four-wheel disc braking system enhanced with larger, 12.8-inch (325 mm) front disc rotors and iron twin-piston calipers, it's not difficult to put a stop to things in the more powerful 9-7X Aero. The heavy-duty iron calipers are stiff and retain their shape under high-pressure/high-heat braking conditions, providing a more linear feel and reduced pedal travel in high-energy stops. The brake pads use high-performance linings for strong fade resistance.
ABS and automatic all-wheel-drive are standard on all 9-7X models as well as the StabiliTrak electronic stability control system that provides confident, sure-footed travel. The performance-oriented all-wheel-drive system delivers impressive on-road grip and enhanced "launch" feel. The always-engaged system uses a Torsen center differential to split torque between the front and rear wheels. It is a torque-bias system that detects low traction at one axle and directs more torque to the other when needed.
Like all 9-7X models, the Aero model represents a terrific value with a high-level of standard equipment. In fact, the 9-7X boasts the most standard features in its class while offering a very competitive starting price at $39,935. The limited edition 9-7X Aero will start at $45,690, which includes a $745 destination fee and will begin arriving at dealerships this fall.
Saab is a division of General Motors Corp. Saab Automobile USA is the importer and/or distributor of Saab 9-3, 9-5 and 9-7X automobiles for Saab Automobile AB, Sweden. In 2007, Saab celebrates 60 years since first being introduced to the automotive scene as the vision-turned-reality of 16 aircraft engineers. Visit www.saabusa.com for more information.
The Swedish lad in the General family has announced the official US pricing of the facelifted 2008 9-3. Starting at $28,385 for the base 2.0T Sedan, it marks a considerable $2135 boost from the $26,250 tag of the 2007 model. The 2008 model heralds new changes made extensively to the exterior, while interior changes are minimal to the best. Spanning the Aero-X Concept cue, the front fascia departs from the clean design of the 2007, but its new sleek design does its job nicely.
Some highlights of the minor changes elsewhere include side sills, new alloy wheel designs, standard OnStar, XM, rain-sensing wipers and a tire-pressure monitor. Saab also announced the pricing of the 2008 SportCombi and the Convertible. Standing $29,630 and $39,710 respectively, the less popular variants of the 9-3 range are also plagued with the price boost syndrome.
Saab will cease production of their short-lived 9-7X SUV next year because of lackluster sales. The 9-7X shares underpinnings with the Chevrolet TrailBlazer and both are built in GM's Moraine, Ohio plant. The TrailBlazer is also in death row as Chevrolet prepares to welcome its successor, which will share underpinnings with the Saturn Outlook. The 9-7X will be replaced by the 9-4X crossover, which will sit on GM's Theta architecure.
The 9-7X was shortly available in Europe by approved importers. The 9-7X was never intended to be marketed outside North America. The deletion of the 9-7X and the TrailBlazer will cease the aged GMT-360 platform as a whole. The demise of the GMT-360 comes the coveted Lambda platform, which is already gaining praises from both the media and the consumers. The Lambda platform underpins the Saturn Outlook, GMC Acadia and the Buick Enclave as of currently.
It's about time Saab just officially reveals the 9-3. After all, the full 9-3 range can be deemed as the worst kept secret of 2007. New unmasked spyshots popped up everyday and all we had to do was wait for the officially official debut. Finally, Saab released a great load of press images of the full 9-3 range, which includes the Sedan, SportCombi and the Cabriolet.
The Aero-X inspired front fascia is the main highlight of the changes that the Swedish automaker has implemented for this refresh. The look is controversial and the reception of the new design is nearly half and half, as some Saab enthusiasts like the cleaner design of the pre-facelift model. With the new front end comes other visual changes including new clear-lens taillights and a new bumper.
Saab also introduced their brand new all-wheel drive system called the XWD. The new quad-steer tech is only available on the top Aero models, which are also equipped with a new 2.8L 280hp V6 turbo. Along with the new turbo V6 is an array of turbo 4-cylinders, two BioPower E85s, and a 1.9L diesel. The Cabriolet version does not get the new XWD system.
Recently, the Saab 9-3 Cabriolet received a Top Safety Pick from IIHS for frontal, side, and rear impact testings for convertibles. The new facelift ought to stay the same. Follow the jump to view hi-res image galleries for all three variants and the official press release.

The Insurance Institute for Highway Safety made history today when they announced results of their first crah testings of convertibles. Out of the 10 new drop-tops they tested, the Saab 9-3 Convertible and the Volvo C70 received the Top Safety Pick. They scored "good" for all three criterias: frontal, side, and rear.
The rear impact tests proved to be the most difficult for these cars as fixed roofs can do a great deal in protecting the cabin and the car itself. The Pontiac G6 Convertible did not do so well in every criteria. Some other vehicles tested were the Chrysler Sebring Convertible, BMW 3-Series Convertible, Mitsubishi Eclipse Convertible, and the Audi A4 Cabriolet. Follow the jump to view the official press release.
1st time Institute tests convertibles: Saab & Volvo models are top performers; 3 are marginal in side impact test
ARLINGTON, VA - The Saab 9-3 and Volvo C70 earn the Insurance Institute for Highway Safety's TOP SAFETY PICK award for superior crash protection in the first tests the Institute has conducted of 10 midsize convertible models. The Saab and Volvo earn the top rating of good for protection in front, side, and rear crashes, and both models include standard electronic stability control (ESC), which research shows can help drivers avoid crashes. The lowest rated convertible model overall is the Pontiac G6. It's acceptable for frontal crash protection but only marginal for protection in side and rear impacts. While the Audi A4 and BMW 3 series earn good ratings in frontal offset tests, both are rated marginal for side impact protection and poor for protection in rear crashes.
The TOP SAFETY PICK designation is intended to make it easier for consumers to find top-rated vehicles without sorting through reams of crash test results. To earn this award, a vehicle must have good ratings in all 3 Institute crash tests. It also must have ESC. The Institute adds a requirement for convertibles which must be equipped with rollbars designed to preserve occupants' headroom if a convertible rolls over. Both the 9-3 and C70 are equipped with standard pop-up rollbars behind the rear head restraints that deploy if sensors detect a serious crash.
"The performances of the 9-3 and C70 are impressive," says Institute president Adrian Lund. "These cars combine what convertible buyers should look for if they're shopping with safety in mind. The Saab and Volvo not only provide good protection in high-speed front and side crashes but also have good seat and head restraint designs for protecting against whiplash in rear crashes."
"We wanted to test convertibles because sales are increasing," Lund says. "We also wanted to evaluate a group of vehicles that automakers wouldn't expect us to test to see if crashworthiness improvements in mainstream cars also are being built into convertibles. For the most part we found that this is happening."
Five models earn the highest rating of good for front and side crash protection. Seven of the 10 convertibles have standard side airbags designed to protect the heads of occupants in the front seats, and 8 have ESC as standard or optional equipment.
Absence of roof is inherent disadvantage: High-speed crashes are violent events, and the roof of a hardtop helps to keep people's heads and arms from flailing outside the vehicle. Roofs also provide protection if a vehicle rolls over. Data from real-world crashes indicate that the overall risk of death isn't higher in a convertible, but this doesn't mean there aren't any safety disadvantages.
The absence of a roof makes it a challenge to design a convertible for safety. The roof helps to maintain the rigidity of the structure around the occupant compartment and keep the compartment intact in a serious crash. The main structures of convertibles have to be strengthened to compensate for the support that's lost in removing the roof. The Institute's crash test results show that many modern convertibles compensate well. For example, the 9-3 convertible achieves the same good front, side, and rear crash test ratings as the 4-door sedan version.
Big price tag doesn't ensure a safer car: While the 2 TOP SAFETY PICK winners are relatively expensive, price doesn't necessarily predict good crash test ratings. Two of the least expensive models among the 10 the Institute tested are the Chrysler Sebring and Mitsubishi Eclipse, both of which recently were redesigned and earn good ratings in front and side crash tests.
"You could spend twice as much for an Audi A4 convertible, which is an older design based on the previous A4 sedan, but it's rated marginal in our side test," Lund says. Based on the Volkswagen Eos's performance, the Institute expects a redesigned A4 to perform better when it's released. VW and Audi are owned by the same parent company.
To reduce the risk if a convertible rolls over, it's important to have rollbars, which may be either fixed in place or deploy automatically if sensors detect the possibility of a rollover. Pop-up rollbars are standard on the 9-3, C70, Eos, 3 series, and A4 but unavailable on any of the domestic or Asian brands the Institute tested.
"It makes sense that a rollbar would help preserve some headroom, just as we hope a fixed roof would," Lund says. "But rollbars aren't the same as having a fixed roof. We don't yet know if convertibles with the bars have lower rollover death rates than convertibles without them.
Another innovation on some new convertibles is that the vinyl or cloth top is replaced by a multipiece hardtop that folds into the trunk. It's standard on the C70, Eos, 3 series, and G6. It's optional on the Chrysler Sebring. Folding hardtops aren't as rigid as fixed roofs so they wouldn't be expected to make a convertible more crashworthy than if the top were soft. Foldtops are for comfort, not safety.
"Of course, without a top all bets are off if you're not using a safety belt. Good test results don't mean convertibles are as protective as comparable hardtop cars," Lund points out.
Problems found in frontal tests: The structure of the Pontiac G6's occupant compartment held up well during the frontal test, but there was a problem with the driver seat. It came loose on one of its tracks and moved forward 4 inches on the left side. The dummy's head slid around the left side of the airbag and hit the instrument panel.
"We've rarely seen a dummy's head hit the instrument panel in our frontal test," Lund says. Overall the G6 is rated acceptable for frontal protection.
"Seats shouldn't come loose in crashes, so we can't rate the G6 good," Lund adds. Measures recorded on the dummy's head, neck, and chest indicate low risk of serious injury in these areas of the body, but the poorly controlled movement of the dummy during the impact may have contributed to high forces on its right leg.
The Institute conducted 2 frontal tests of the Mustang. In the first test, the driver door partially opened late in the crash. Even though this didn't significantly affect the driver dummy's movement during the impact, doors shouldn't open because in some crashes this could lead to partial or complete ejection of occupants.
Ford engineers found that the window glass in the down position pushed on the door latch during the crash. Structure was added in the door to prevent the glass from contacting the latch mechanism, and then the engineers asked the Institute to test the Mustang again. In the second test with the change, the door remained closed.
The Mustang is rated acceptable instead of good overall because the structure isn't good, and the dummy's head bottomed out the airbag. The resulting head acceleration was high. The head was struck by the windshield pillar.
Side impact protection is marginal in 3 cars: The Institute's side test represents what happens when the striking vehicle is a pickup or SUV. The BMW 3 series and Audi A4 equipped with standard side airbags and the G6 with side airbags as optional equipment earn the second lowest rating for side impact protection.
"The 3 series and Pontiac G6 are especially disappointing because they're new models," Lund says. "Other auto manufacturers have figured out how to provide good side impact protection for occupants of convertibles."
The G6 is equipped with optional side airbags designed to protect the torsos but not the heads of front-seat occupants. In the side test, the driver dummy's head struck the windowsill. This caused a high head acceleration. In a real-world crash of similar severity, a serious skull fracture and brain injuries would be possible. A taller person's head also might be struck by the hood of an oncoming SUV or pickup.
The 3 series is equipped with standard side airbags designed to protect front-seat occupants' heads as well as their torsos. However, injury measures recorded on the driver dummy indicate the possibility of rib fractures and internal organ injuries in real-world crashes of similar severity.
"None of the 10 convertibles provides side airbag protection for people riding in back seats. We didn't record high injury forces on any of the dummies in the back seats, but in a crash at a different speed or configuration the heads of back-seat passengers would be at risk without side airbags," Lund notes.
Rear crash protection is mostly poor: Significant differences also were apparent among the convertibles in the protection they afford in rear crashes. Only the Volvo and Saab are equipped with seat/head restraint designs that provide good protection against whiplash injury. The other 8 models are rated marginal or poor for rear crash protection.
"It isn't hard or expensive to design a seat to prevent neck injury in a rear-end crash," Lund says. "Some of these manufacturers like Audi, Ford, and Volkswagen already have seat designs elsewhere in their lines of vehicles that are rated good for whiplash prevention, but these automakers haven't put the good seat/head restraints in their convertibles."
How vehicles are evaluated: The Institute's frontal crashworthiness evaluations are based on results of 40 mph frontal offset crash tests. Each vehicle's overall evaluation is based on measurements of intrusion into the occupant compartment, injury measures recorded on a Hybrid III dummy in the driver seat, and analysis of slow-motion film to assess how well the restraint system controlled dummy movement during the test.
Side evaluations are based on performance in a crash test in which the side of a vehicle is struck by a barrier moving at 31 mph. The barrier represents the front end of a pickup or SUV. Ratings reflect injury measures recorded on 2 instrumented SID-IIs dummies, assessment of head protection countermeasures, and the vehicle's structural performance during the impact. Injury measures obtained from the 2 dummies, one in the driver seat and the other in the back seat behind the driver, are used to determine the likelihood that a driver and/or passenger in a similar real-world crash would sustain serious injury to various parts of the body. The movements and contacts of the dummies' heads during the test also are evaluated. Structural performance is based on measurements indicating the amount of B-pillar intrusion into the occupant compartment.
Rear crash protection is rated according to a 2-step procedure. Starting points for the ratings are measurements of head restraint geometry - the height of a restraint and its horizontal distance behind the back of the head of an average-size man. Seat/head restraints with good or acceptable geometry are tested dynamically using a dummy that measures forces on the neck. This test simulates a collision in which a stationary vehicle is struck in the rear at 20 mph. Seats without good or acceptable geometry are rated poor overall because they cannot be positioned to protect many people.
Now, we really think Saab's on a break lately. Only recently, we provided you with shots of the Convertible variant of the 9-3 facelift roaming around in public streets. Shots of the Convertible with no tapes emerged before that, and we've already seen plenty shots of the SportCombi facelift sans disguise. However, it's the first time we bring you undisguised shots of the Sedan variant undergoing testing courtesy of SaabTurboClub.
The new Saab will host many different changes other than the new front-end, including an upgraded audio system, adaptive Xenon headlights, a boosted 255hp engine for the Aero trim, and black leather interior replacing the gray leather option. Saab hopes the new changes made will bost the slowing sales of the 9-3 in the US.
It seems that new spyshots of the Saab 9-3 facelift, Cabrio or Estate, pop up just too often these days. Mind that they're also pretty clean shots with all of them so far showing light or no camo. A member over at Saabturboclub snapped decent pics of the Saab 9-3 Cabrio facelift testing relatively without care on public streets. In one of the pics, you can see a Saab dealer nearby. Anyways, all the details we spilled are in our previous post. More pics are after the jump.
Looks like Saab folks have been pretty careless lately as the upcoming 2008 9-3 (has been caught unguarded and unmasked for the second time this month not by pros but by a random reader. Following the revealing 2008 9-3 SW snap shots an AMS reader managed to catch an unmasked facelifted 9-3 Convertible parked at a petrol station just begging to be immortalized by his cell phone camera.
Continued- Article, two more shots In comparison with the facelifted SW we showed you a couple of weeks ago the Convertible gets the same 9-5 inspired front end with the “Aero-X” type grille and eyelash-headlights. The difference is that the Convertible features a different bumper and heaps of chrome accents that make it look very busy. In the rear-end the facelift Convertible gets a set of clear tail lamps and a chrome insert while the bumper looses its protective pads. Unlike the sedan and SW versions, the redesigned soft-top 9-3 doesn’t get the Cadillac BLS door handles.
The 2008 9-3 Sedan, Cabriolet and SW versions will go on sale this fall but there’s a good chance that we'll see the first official pictures quite sooner as according to inside info, GM's planning to reveal initial info in mid May.
Pictured here is the facelifted Saab 9-3 undergoing final testing ahead of its launch in roughly one month’s time. Though the changes to the car’s exterior seem minor, under the revised sheet metal it’s a totally different story. First up, Saab will be introducing an AWD system sourced from Haldex that’s rumoured to feature a new electronic differential. The new diff is said to be better suited at distributing force during slides and contributes to stabilizing the car around corners.

Continued- Article, link to more images In addition to the new AWD system, Saab engineers have upgraded the turbo V6 engine, which is expected to output close to 300hp in the new Aero model. Visual enhancements include the new clear, vertically stacked taillights on the wagon model. Up front, the car picks up chrome highlights surrounding the headlamps and a new grille design inspired by Saab’s Aero X concept.
The launch date for the updated 9-3 is scheduled for mid may with official images set to be published by the first week.
CARSCOOP's little chit-chat with a Saab PR last week wasn’t only about the facelifted 9-3 that’s coming this fall with a new AWD version fitted with a 290Hp 2.8 V6 Turbo engine, as we also learned that Saab will debut its first-ever compact SUV, the 9-4X, towards the end of 2008.
Although not officialy confirmed, it’s rumored that Saab’s 9-4X will be based on the next-gen Opel Vectra / Saab 9-3 / Cadillac BLX platform. Talking about Cadillac, the American car-maker will also produce their versions of the Saab 9-4X, both of whom will compete against the likes of BMW’s X3 and the upcoming Mercedes MLK, Volvo XC60 & Audi Q5 SUV’s. Back to Saab, GM’s Swedish-arm will probably tease us with a prototype version of the 9-4X in the upcoming months but until then; check out a bunch of computer-generated renderings from the swedish mag, Teknikens Varld.
Who needs spy photographers when you’ve got readers that manage to take shots of totally undisguised future models like the 2008 MINI Clubman featured in our previous post or the Saab 9-3 Facelift shown here! Thanks to an eagle-eyed reader of Swedish magazine TeknikensVarld who was thoughtful enough to share the cell-phone pics we won’t have to wait till autumn to see how Saab will integrate the 9-5 grille to the 9-3.

Continued- Article, two more shots However, the redesigned front-end and the Cadillac BLS door handles aren’t the only highlights of the facelifted 9-3. We spoke to a Saab PR and apart from learning that 2008 9-3 will be presented at the Frankfurt Show in September with European sales starting in October, we were informed that the new top-of-the-range 9-3 will be equipped with AWD and an upgraded version of GM’s 2.8-liter V6 Turbo pumping out approximately 290Hp.
Inspired by the Aero X Concept which debuted at Geneva 2006, Saab is apparently looking to get the 9-3 mid-size saloon, estate and – seen here – cabrio a new front end with a bigger and somewhat more aggressive grille with one huge center section flanked by two smaller air-intakes left and right.
[Source: WorldCarFans]
Continued- Article, more shots Like on the 9-5, we expect a bit of chrome in the grille and on the upper edges of the headlamps. The bumpers front and rear will get a little makeover, too, mainly characterized by the missing rubber strips which are as well lacking on the doors. This together with new door handles will give the 9-3 an even more elegant look. The modern-style taillights will be left unchanged, though. We expect presentation of the re-designed 9-3 right in time for the celebrations of the 60th anniversary of the Swedish make.
Saab is currently developing its first hybrid model based on technology gained from parent company General Motors. Speaking with Reuters at this week’s Geneva Motor Show, Saab’s Managing Director Jan Ake Jonsson told reporters that the decision will allow it to reduce development costs thanks to parts sharing with other models within the GM family.
[Source: Motor Authority]
Continued- Article GM partnered with DaimlerChrysler and BMW to co-develop the new hybrid technology, which are also developing hybrid vehicles of their own. Mercedes-Benz revealed on Tuesday that it will be releasing a hybrid car by 2009, while BMW made the statement that it would start production of its own hybrid in two years time.
Jonsson wasn’t willing to give a launch date for the new Saab hybrid but said that it was just one avenue of green technology that it was currently investigating. Saab also used the Geneva event to showcase its new enviro-friendly 9-5 SportCombi sedan powered by a 300hp turbocharged engine that can run on 100% ethanol.
The Saab BioPower 100 Concept, presented at the Geneva Motor Show, showcases the first production-based turbo engine to be optimized for pure, eco-friendly bioethanol (E100) fuel. The result is a level of performance never seen before from a road car using this fuel. This exciting concept takes Saab BioPower technology to a new level by showing the true potential of combining turbocharging and sophisticated engine management with pure bioethanol fuel. And in demonstrating that greener motoring means even sportier driving, it also extends Saab's technical leadership of Europe's emerging 'flex-fuel' segment.

PRESS RELEASE:
Saab BioPower 100 Concept: Bioethanol Performance Potential Unleashed
The Saab BioPower 100 Concept, presented at the Geneva Motor Show, showcases the first production-based turbo engine to be optimized for pure, eco-friendly bioethanol (E100) fuel. The result is a level of performance never seen before from a road car using this fuel.
This exciting concept takes Saab BioPower technology to a new level by showing the true potential of combining turbocharging and sophisticated engine management with pure bioethanol fuel. And in demonstrating that greener motoring means even sportier driving, it also extends Saab's technical leadership of Europe's emerging 'flex-fuel' segment.
At the heart of the Saab BioPower 100 Concept is a modified version of a 2.0-liter turbo production gasoline engine from the current Saab 9-5 range, which in standard specification gives peak power of 150 hp. A test and development program - involving modifications to the engine management system and internal components - now enables it to exploit the high octane benefits of E100 fuel by using a higher compression ratio, together with more boost pressure. The outcome of this work is peak power of 300 hp and a remarkably high specific power output of 150 hp per liter.
"This exciting concept shows the tremendous potential of bioethanol, in terms of both performance and future opportunities to 'rightsize' engines," says Jan Åke Jonsson, Saab Automobile's Managing Director. "Bioethanol is already entering the European market as E85 fuel and we look forward to seeing further supply infrastructure developments that will make it more widely available in the future."
The Saab BioPower 100 Concept is presented as an evolution of the Saab 9-5 SportCombi. It is visually distinguished by styling features such as 'ice block' front and rear light units - extending a theme seen on the 9-3 SportCombi - and 19-inch 'turbine' alloy wheels inspired by those of the award-winning Saab Aero X concept, first shown at Geneva last year. The interior is upholstered in unique white leather, complemented by the main fascia and door trims, which are finished in black leather overlaid with a carbon fiber-effect pattern. The car is also equipped with Saab's innovative AlcoKey, an easy to use, pocket-sized alco-lock device that helps drivers steer clear of drinking and driving.
Total BioPower
Saab is already established as the leading player in Europe's emerging market for 'flex-fuel' vehicles able to run on gasoline and/or bioethanol (E85). Its current Saab 9-5 BioPower model is the best-selling flex-fuel car in Europe and Sweden and, at Geneva this year, Saab also announces BioPower's introduction throughout its 9-3 product range.
So far, Saab BioPower development has been focused on using E85 fuel, (85% bioethanol/15% gasoline). Now, with the announcement of the fully functioning BioPower 100 Concept, Saab confirms its leadership position by showing how bioethanol technology could be further extended. In combining pure bioethanol with Saab's expertise in turbocharging, the BioPower 100 Concept offers drivers an exciting win/win proposition: greener motoring with dramatically enhanced power and performance.
Running on E100, the concept car´s engine delivers peak power of 300 hp at 5,800 rpm and an exceptionally strong 400 Nm of torque between 3,000 and 5,100 rpm, withalmost 85% available at just 2,000 rpm. This strong and flexible power delivery gives the Saab BioPower 100 Concept car zero to 100 kph acceleration in just 6.6 secs and 80 - 120 kph (fifth gear) in an even more impressive 8.2 secs. The standard 150 hp gasoline engine produces 240 Nm of torque from 1,800-3,500 rpm, giving zero to 100 kph in10.2 secs and 80-120 kph (fifth gear) in 16.3 secs.
The secret behind such enhanced performance is the ability of E100 fuel to resist harmful self-ignition, or 'knocking', as the fuel/air mixture is compressed in the cylinder. This attribute is denoted by E100's high 106 RON octane rating. It permits the use of an engine compression ratio that is higher than normally possible with turbocharging, giving more power and greater combustion efficiency without risk of knocking.
The BioPower 100 Concept's engine operates with a compression ratio of 11.0:1, compared to 8.8:1 for the standard gasoline engine. This has been achieved by modifying the shape of the piston crowns to reduce the volume of the combustion chamber, thereby raising the engine's compression ratio.
New software for Saab's powerful Trionic engine management system, which controls the throttle setting, ignition timing, fuel injection and turbo boost pressure, looks after the different ignition timing and fuel/air mixture requirements of E100 fuel.
More durable valves and valve seats are fitted to the engine, together with bioethanol-compatible materials throughout the fuel system. The only other modification necessary is pre-heating of the fuel. This is required to achieve good cold-starting performance, which is the main reason why bioethanol is currently blended with gasoline and sold as E85 fuel.
In ambient temperatures below 15°C, the chemistry of E100 makes it resistant to vaporization and, as a result, it can be difficult to start the engine. To overcome this issue, the Saab BioPower 100 Concept has an experimental fuel heating system, using small heating elements in the inlet ports downstream of the injectors. When the engine is cold, these elements warm the incoming fuel sufficiently to allow it to vaporize. Shortly after start-up, the function is automatically deactivated.
On The Road
In optimizing the potential of bioethanol fuel, the Saab BioPower 100 Concept turbo engine offers improved driveability, as well as greater full power performance. The high compression ratio allows the engine to generate more torque more quickly, particularly from low engine speeds. On the road, the driver of the BioPower 100 Concept will immediately notice a sharper engine response, with a better low speed pick-up before the turbo is engaged.
On full throttle openings, the turbocharger packs up to 1.2 bar boost, without risk of 'knocking' from the high octane fuel. It gives the BioPower 100 Concept driver access to the sort of in-gear performance typical of a modern, naturally-aspirated engine of four liters or more. The smooth power delivery - without fossil fuel emissions - takes Saab's traditional 'less is more' turbo philosophy to a new level.
That impressive 150 hp/liter specific power output also indicates considerable future potential for engine 'rightsizing', giving the driver the performance characteristics of a 'large' engine without incurring its additional weight, greater complexity or higher fuel consumption. In this way, E100 offers significant potential to reduce the displacement of an engine - thereby reducing fuel consumption - while still achieving a desired power level.
The overall fuel consumption of the current Saab 9-5 BioPower engine using E85 is about 30% higher than on gasoline and the optimized BioPower 100 engine is expected to yield a near 10% gain against this. Bioethanol burns at a lower temperature than gasoline, which reduces thermal stresses on the engine and benefits fuel consumption at higher cruising speeds. With the future addition of direct injection and lean-burn technology, E100 fuel consumption can move even closer to gasoline levels.
For optimum energy saving, future E100 applications could also be combined with electric hybrid technology, reducing fuel consumption and CO2 emissions still further. This development has already been previewed in the Saab BioPower Hybrid Concept, the world's first such vehicle to use pure bioethanol.
Whilst the BioPower 100 Concept is focused on performance, it still retains a 'flex-fuel' capability and the engine will also run on gasoline, or E85, although power levels are not so high. Trionic monitors fuel quality after every visit to the filling station and automatically makes any adjustments necessary for running on E100/E85 and/or gasoline in any combination.
To handle the increased performance, the BioPower 100 show car is fitted with a limited-slip differential and larger front brake discs (345 mm) and calipers, while using the sports chassis settings of Saab 9-5 Aero SportCombi. It also has a dual pipe rear exhaust system, with tailpipes similar to those of the Aero X Concept.
Superb Fuel
Bioethanol is a clean burning fuel that can be produced in many parts of the world from a wide range of agricultural crops and biomass. More efficient second-generation processes, using ligno-cellulose extracted from forestry and agricultural products, are also under development.
Bioethanol's simple, fixed chemical composition opens up new possibilities in engine management and control. It consists of just one hydrocarbon molecule, whereas retail gasoline is a cocktail of several hundred different hydrocarbons, as well as additives to prevent engine deposits which may not be necessary with bioethanol. It is also biodegradable and will dissolve in water.
As it is a single chemical compound, bioethanol allows engineers to exercise much greater precision in maximizing engine performance. For example, it is possible to maintain an ideal fuel/air mixture (Lambda 1) at all throttle openings without impairing the smooth running of the engine.
Saab's experimental variable compression (SVC) engine, revealed at Geneva in 2000, has played an important role as a test bed for BioPower development work. It has been used to help determine the optimum relationship between compression ratio and boost pressure for the BioPower 100 application.
"Bioethanol is a potent, high quality fuel which opens up exciting possibilities in helping to meet the environmental challenges that face us," says Kjell ac Bergström, President and CEO, GM Powertrain - Sweden, who has led the Saab BioPower 100 engine development team.
He adds: "As the need to reduce energy consumption increases, we are exploring ways to run smaller engines that give relatively high power, with and without hybrid technology. Bioethanol can play a key role in this 'rightsizing' process, while also minimizing fossil fuel emissions."
Helping to Prevent Drink-Driving
The Saab BioPower 100 Concept incorporates Saab's innovative AlcoKey, a vehicle 'alcolock' system designed to prevent the car being used if a driver is under the influence of alcohol.
The pocket-sized AlcoKey unit incorporates a cap covering a mouthpiece where the driver provides a breath sample before starting the car. Its radio transmitter then sends a signal to the engine's electronic control unit. This will allow the car to be started or, if the breath sample is found to contain alcohol above the permitted legal level, keep it immobilized.
AlcoKey recently won the Swedish Automobile Association's annual award for innovation and it is currently on user field trials in Sweden, where car fleet operators and public service providers want an effective means of reassuring the public that drivers cannot get behind the wheel if their blood/alcohol level is over the limit.
The field trials are focused on verifying AlcoKey's convenience and ease of use. Its transmitter has a range of up to 10 meters and if a breath sample is provided before entering the car, its quick three to four second clearance process should not delay the driver. In everyday use, AlcoKey can provide a useful check if a driver has had a drink some time before intending to drive or has been drinking the night before. It could be offered as an option for Saab 9-5 and 9-3 models sold on the Swedish market, priced at around SEK 3,000.
With the introduction of the new 1.8t BioPower in Saab’s 9-3 line of cars, the Swedish carmaker’s entire range can now be optioned with flex-fuel drivetrains. The new model range will make its debut at next week’s Geneva Motor Show, including the Sport Saloon, Sport Wagon and Convertible. The 1.8t BioPower engine emits 50-70% less carbon dioxide (CO2) than its 1.8t petrol engine equivalent, yet produces 17% more power and 10% more torque when running on the eco-friendly E85 fuel.
The cars will be available with manual or automatic transmissions and will go on sale in the UK soon after its Geneva Debut, with sales across the rest of Europe scheduled to start later this year. There’s no word on which other markets will get the new flex-fuel models.
The turbocharged and intercooled engine produces 175hp (129kW) at 5500rpm and peak torque of 265Nm from as low as 2500rpm up to 4000rpm. The 0 – 100km/h time takes 8.4 seconds for the manual 9-3 Sport Saloon, while top speed is 137mph.
Stay tuned for more images and the official press release when it becomes available.
Saab customers, VIP guests and dealers from all over the world are being greeted with an ‘iced’ 9-3 Convertible when they arrive for the Saab Ice Experience event at Sweden’s world famous ICEHOTEL. Saab broke the ice, more than 20 years ago, when it pioneered the concept of an open-top car providing practical, year-round transport. So it was clearly a cool idea to ‘freeze frame’ the latest Saab 9-3 Convertible in a garage made from ice at the hotel, near Jukkasjärvi in northern Sweden, 200 kilometers north of the Arctic Circle.
Visible at night from a kilometer away, the icy reflections of the convertible’s illuminated bright blue paintwork give arriving guests an automotive interpretation of the Northern Lights. The installation, added to this year’s version of the ICEHOTEL, is made from 60 ice blocks, weighing 30 tons, all harvested from the nearby Torne River, one of Europe’s purest.

Saab is celebrating its 60 years of automotive manufacturing this year and the 9-3 Convertible model was chosen to light up the sky. About 500 guests will attend the event, which finishes on March 18, although test-driving will not include the ice-bound convertible.
“Snow and ice are core elements of Scandinavian nature, so it was a very natural step for us to adopt this theme for our Convertible, the original car for all seasons.” says Marie Larsson, Saab event project manager.
“ Sweden also has a strong tradition for environmental care. For example, the ice used to build this hotel is a renewable resource that is recycled each year when it melts and returns to the river. In a similar way, our Saab BioPower engines are able to run on bioethanol, a renewable fuel with a greatly reduced CO 2 impact.”
Just in time to celebrate Saabs 60 year anniversary this summer, the 9-3 gets a new face. After having already caught photos of a Saab 9-3 station wagon prototype, here are new photos showing that the 9-3 convertible will also get a restyling. The current convertible has been on the market since 2003.
The powerful style of the new front, with the bigger grille, is inspired from the Aero X Concept. Other trademarks from the Concept are the smaller side grilles and the v-shaped hood. Expect some chrome in the grilles and also a chrome stripe on the upper side of the headlamps.
Both the front bumper and the bumper in the back are new, and together with the missing décor stripes on the doors as well on the bumpers, it gives the new 9-3 a cleaner look. Also the door handles are new. It looks like they are the same as on the Cadillac BLS. The shape of the rear lights will remain the same, but there will be optional LED lights.
Saab has been a big supporter of E85 vehicles in recent years and will be taking the next step to E100 in its new Biopower 100 Concept destined for the Geneva Motor Show. The concept showcases the first production-based engine to be optimized for pure bioethanol (E100) fuel.
The optimized 2.0L engine from the 9-5 develops 300hp of power thanks to the high octane of E100 fuel. That exceptionally high specific power output of 150hp/L demonstrates scope for future ‘rightsizing’, using smaller, high output engines that also deliver energy savings. The engine also develops 295lb. ft. of torque, which helps to propel it from zero to 62 mph acceleration in just 6.6 seconds and 50 – 75 mph (fifth gear) in only 8.2 seconds. The use of Ethanol and Ethanol blend fuel is still being debated in many countries, but it’s good to know we’ll still be able to get high-performance engines either way. We just wish Saab would repackage the concept in a nicer exterior, like the stunning Aero-X concept.
Stay tuned for more images and the official press release when it officially makes its world debut in Geneva next month.
While the GMT-360 line-up is slowly dying off by the day, Saab decided to continue with the 9-7X by unexpectedly introducing the Aero variant for 2008. The eye-catcher in this newsflash is the beast under the hood. Equipped with a 6.0L LS2 V8 powering 390hp, the engine can propel the high-performance SUV to 60mph in less than six seconds. The exterior receives a lone Carbon Flash Metallic paint and 20-inch polished alloy wheels. Interior changes are minor to the best with Aero-embroidered seats and embossed floormats.
