Saab has once again used Geneva as the launch pad for a new concept vehicle, the 9-X BioHybrid.

The 9-X BioHybrid is based off of previous Saab concepts like the Aero X and earlier 9-X designs. The basic sleek shape of the vehicle could plausibly fit in on today's roads, with its long roofline, 'shooting brake' silhouette, and wraparound windows. It looks like a longer version of a sporty hatchback.

The reason this concept has the word 'hybrid' in its name is because it uses GM's next-generation hybrid system. Optimized for E85 fuel, this 9-X hybrid uses a 1.4-litre BioPower turbocharged engine that gives it an estimated fuel economy rating when running on regular gasoline of just 4.9 L/100 km. When using E85 fuel, the numbers are still impressive at 6.4 L/100 km.

In terms of performance, estimated numbers include a 0 - 100 km/h time of 7.9 secs (E85) and 8.3 secs (gasoline), 80 -120 km/h time (5th gear) of 8.8 secs (E85) and 11.2 secs (gasoline) and a top speed of (6th gear) of 216 km/h (E85) and 192 km/h (gasoline).

In addition, the vehicle also uses an electric motor powered by a lithium ion battery pack, which is stored under the rear cargo floor. The electric motor adds more power during acceleration, and is used to re-start the engine, supporting the automatic fuel-saving function whenever the car is stationary. The hybrid system also enables a longer fuel cut-off during deceleration and braking. Combined, the car produces 200-horsepower and 207 lbs.-ft. of torque when using E85 fuel, and 170-horsepower and 170 lbs.-ft. of torque when using regular gasoline.

These components are mated to a 6-speed manual transmission. The vehicle uses rack-and-pinion steering with electrical power assistance and rides on 21-inch wheels and tires.

The 9-X BioHybrid's battery is not only recharged using regenerative braking (which is the case in most current hybrids), but also using the large solar cell in the car's glass roof. It helps with the regeneration both while parked and while moving, and looks good at the same time.

Also as is the case with so many recent Saab designs, the 9-X BioHybrid makes use of Saab's aircraft roots. Not only is it very aerodynamic, but the car's upper and lower bodywork actually reshapes at speeds exceeding 70 km/h, as the roof spoiler automatically extends and an underbody diffuser is deployed from the bottom of the rear bumper.

The interior of the 9-X BioHybrid, meanwhile, is much different from many of Saab's current interior designs. Instead of a central, floor-mounted console, the driver-focused layout incorporates a main instrument panel that sweeps out from the top of the door moulding, arching across the driver. The embedded 3-D graphics appear to be ‘frozen' in ice according to Saab, which continues a Scandinavian design theme first seen in the Aero X.

A wireless interface inside the vehicle makes use of streaming data, entertainment and satellite navigation functions.

When it comes to functionality, the BioHybrid still takes on the traits of a typical hatchback. The extra room in the rear is a big help, made even more convenient thanks to an electrically-powered slide-out floor, which is activated when the bottom half of the split tailgate drops down. The floor and the back of the rear folding seats are covered in high-friction rubber carpeting, which grips items that are places on the floor.
