This is a little late as it is a Detroit concept, but since the Saab 9-4X Biopower Concept will be one of the two concepts shown by the boys from Trollhattan at the 2008 Geneva Motor Show, and it will be the concept’s first public European debut.

On the outside you have a rather sleek SUV that carries all of Saab’s styling cues, especially the three section grille at the front, also seen on the new Saab 9-3 and the Saab Aero X Concept. On the interior, you have a typical Saab interior, with a black dash and driver-oriented instrumentation which lights up in a signature Saab green.

The all-wheel drive underpining the Saab 9-4X Biopower Concept is Saab’s Cross Wheel Drive system from Haldex, which features torque vectoring to channel power to the wheel with the most traction without cutting off engine power or applying the brakes. It also automatically adjusts torque bias to help the vehicle follow the course set by the driver. The chassis rides on MacPherson struts at the front couple with aluminium control arm and knuckle, and an anti-roll bar, while the rear suspension uses a multi-link setup with aluminium H-arm and knuckle, and an anti-roll bar.

Under the hood is a bioethanol capable engine, a Saab speciality since two thirds of all car sales in Saab’s home ground of Sweden come with flex fuel engines. The Saab 9-4X Biopower’s 2.0 litre turbocharged direct injection all-aluminium engine with variable valve timing is E85 bioethanol capable, and produces 300 horsepower at 5,400rpm and 400Nm of torque between 2,600rpm and 5,100rpm, if fueled with E85. Using regular gasoline, the BioPower engine puts out 245 horses at 5,300rpm and 353Nm of torque between 2,500rpm to 5,250rpm.

The turbocharger is a single twin-scroll unit, blowing a 1.2 bar boost pressure. Thanks to direct injection, this boost pressure can be used together with a high compression ratio of 10.5:1. The engine is mated to a 6-speed automatic with manual shifting via steering wheel controls.

Preliminary testing shows a 0 to 100km/h time of 8 seconds, and a top speed of 235km/h. Look at more photos of the Saab 9-4X BioPower Concept SUV after the jump.
