Saab 9-X BioHybrid Concept
First shown to the world at the 2008 Geneva Auto Show, the Saab 9-X BioHybrid Concept is a tale of two propulsion systems. One is this compact hatchback's internal combustion engine: a turbocharged 1.4-liter 4-cylinder optimized to run on E85 ethanol. That fuel's higher octane rating allows it to produce 200 horsepower and 207 lb-ft of torque. Using traditional gasoline drops the power output to 170 horsepower and 170 lb-ft of torque.
The other part of what makes the BioHybrid go is its electric power assist. Consider it an updated version of the battery-powered electric motors that are used in the Saturn Aura Green Line midsize sedan. The hybrid system shuts down the gasoline engine when the vehicle is decelerating and at a stop. It also provides a power boost to supplement the gas engine.
A large solar cell on the BioHybrid's roof captures the sun's energy to further recharge the battery pack. Power gets to the pavement via a 6-speed automated manual transmission. On E85, Saab pegs the BioHybrid's 0-60 mph acceleration time at 7.9 seconds. Estimated fuel economy, using the European city/highway model, is 37 mpg on E85 and 48 mpg on gas.
