The 9-4X BioPower features a 2.0-litre turbocharged engine that runs on E85 bio-ethanol (85 percent ethanol and 15 percent gasoline) producing 300 HP and 295 lb/ft (400 Nm) of torque and it is mated to Saab's XWD ("cross-wheel-drive") system. -Images and details after the jump
PRESS RELEASE: INNOVATIVE 9-4X BIOPOWER CROSSOVER CONCEPT
SIGNALS SAAB PRODUCT EXPANSION
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 Ake 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, the 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. 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
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.

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.
