OFFICIALLY OFFICIAL: Saab 9-4X BioPower Concept for real this time
The doors have been unofficially thrown wide open on the Saab 9-4x BioPower concept after a Dutch media outlet spilled the beans earlier today. The 9-4x is badged as a concept, but the reality is that we will see new CUV probably sometime in 2009. The 9-4x and a new Cadillac that will likely look almost exactly like the Provoq Concept and
During the preview of the 9-4x, it was stated that Saab has tremendous support from the corporate overlords to be stewards of a niche brand. Saab has avoided the quirky aspects of its heritage while bringing forward elements like the shape of the forward sloping D-pillar, which reflects the contours of the classic Saabs like the 99 and 900. Similarly, the blacked out A-pillars recall the wrap-around windscreens of those classic Swedes and the Aero X concept. They've focused on the clean, crisp aspects of Scandinavian design while eliminating any fru-fru like cladding or imitation fender vents. When GM Design VP Brian Nesbitt talked about the 9-4x, he spoke of the design language being the look of Saab going forward. Read on after the jump.

One of the most important elements that Nesbitt highlighted was the face. Most of the great brands have a distinctive face that immediately identifies them as what they are. Think Mercedes-Benz, Audi, BMW and Rolls-Royce. Saab wants to do the same with the three-port grille as seen previously on the new 9-3 and Aero X concept. The ducts below the front bumper reflect some of Saab's aviation heritage invoking images of the air intakes on fighter jets.
On the inside, Saab has kept the usual cockpit design going with all the gauges and controls tilted toward the driver. While the flush mounted controls on the center stack look cool, clean and uncluttered, it looks like it has the potential to be really difficult to use while driving.
Mechanically the new cross-over retains the Haldex designed Cross-Wheel-Drive setup that's available on the 9-3. It's a torque vectoring system that works in conjunction with the stability control to send drive torque to wheels that have traction, but also biases the distribution to help the vehicle follow the course requested by the driver. The drive torque is provided by the latest version of Saab's BioPower engine.
Saab has been a major proponent of ethanol, particularly in its home base of Sweden where two thirds of all sales are now flex-fuel engines. It makes sense for Saab to promote ethanol since it can help enhance the performance of its predominantly turbocharged engines. The turbocharged four-cylinder engine in this new CUV is optimized for use with E85 and gets 300 hp from it's 2.0L displacement along with 295 lb-ft of torque from 2,600-5,100 rpm. Truly impressive numbers for such a small motor. The aluminum block engine also has direct injection and variable valve timing, all helping it get the most out of every drop of alcohol.
INNOVATIVE 9-4X BIOPOWER CROSSOVER CONCEPT
SIGNALS SAAB PRODUCT EXPANSION
DETROIT – The Saab 9-4X BioPower Concept, revealed today at the North American International Auto Show, confirms Saab's plans to enter the growing crossover segment with a dynamic, driver-focused vehicle inspired by Scandinavian design values and respect for the environment.
The concept's progressive design features are combined with a responsible, fun-to-drive appeal based on BioPower engine technology and a cutting-edge all-wheel-drive system.
"This concept is a clear statement of what our brand is about," said Jan Åke Jonsson, Saab Automobile Managing Director. "It is also an important next step in our plans to enter new market segments with distinctive product offerings."
The design of the Saab 9-4X BioPower Concept reflects a Scandinavian principle of simplicity of form, with clean and uncluttered lines, free of any cladding, moldings or roof bars, and defining "ice-block" surface and lighting themes. The progressive frontal styling and interior design elements also draw inspiration from Saab's widely acclaimed Aero X concept. Innovative load-carrying solutions include a unique ski equipment stowage system, developed with mountain sports specialists Salomon. (Please see accompanying Salomon release.)
Optimized for bioethanol (E85) fuel, t he four-cylinder, 2.0-liter BioPower turbo engine demonstrates Saab's commitment to "rightsizing" – achieving sufficient levels of performance with a smaller, more efficient engine – by delivering 300 horsepower (221 kW) and strong torque of 295 lb.-ft (400 Nm), together with substantially reduced CO 2 emissions on a source-to-wheel basis. (Please see accompanying Powertrain release). The key enabler for rightsizing is turbocharging technology, which Saab pioneered 30 years ago.
Mated to the industry-leading Saab XWD ("cross-wheel-drive") system, this advanced powertrain promises to make driving to a destination as enjoyable as the adventure itself.
The Saab 9-4X BioPower Concept was developed by a team headed by Anthony Lo, GM Europe's Director of Advanced Design, in cooperation with designers and engineers from the Saab Brand Center in Sweden. "We focused on incorporating design themes from the Aero X in a crossover execution, adding functional, lifestyle features to support the activities of customers using this type of vehicle," Lo said.
The driver-focused cockpit in the sporty, four-seater cabin features an Aero X-inspired "clear zone," with a flush-mounted starter button and infotainment controls, that sweeps up from the central console to the main display screen. Signature green lighting is used for all instrument illumination, while other subtle references to Saab's aviation heritage include the "altimeter" speed read-out scale and aircraft-shaped trim on the steering wheel. The panoramic glass roof is in harmony with a car designed to deliver the enjoyment of outdoor pursuits.
Saab designers worked with top Saab Salomon Big Mountain skiers to devise an innovative storage system for stowing skis and equipment inside the car. The rear cargo deck features a sliding floor with a fold-out aluminum ski holder, through which up to three pairs of skis and poles can be slotted. Boots are stowed in an underfloor, heated compartment and, for maximum practicality, the entire rear cargo area is covered in a waterproof and scratch-resistant rubber skin.
The compact, all-aluminum, four-cylinder BioPower engine combines the benefits of turbocharging, direct injection and variable valve timing for the first time with high-octane E85 fuel (85 percent ethanol and 15 percent gasoline). It's a green, rightsizing formula that gives strong power (300 horsepower [221 kW] and 295 lb.-ft. [400 Nm] of torque without the additional weight, size, fuel consumption and higher emissions of a larger, naturally aspirated engine offering similar performance.
Driver involvement is taken to a new level by the innovative all-wheel-drive system, Saab XWD, already available in the 9-3 range. Active management splits torque delivery between both the axles and the rear wheels, via an electronically controlled rear limited-slip differential (eLSD). This responsive system rewards the driver by giving an enhanced, "positive force" chassis balance. Overall, the Saab 9-4X BioPower Concept is a vivid demonstration of Saab's commitment to customers with outdoor leisure interests who seek a sporty driving experience that is in harmony with nature.
