Saab is giving the world a preview of their newest model with the 9-X BioHybrid that's debuting in Geneva this week. The new 9-X is a premium compact intended to compete against cars like the MINI. When this car does go on sale in the next couple of years the name will probably change to 9-1 in keeping with brands nomenclature where X typically describes an all wheel drive model and the second digit indicates the place in the size pecking order.
As the concept's BioHybrid name implies, the little Saab carries forward the ethanol flex-fuel capability of most recent vehicles from the Swedish brand and adds hybrid functionality as well. The engine in the 9-X is a 1.4L turbo four cylinder that puts out 200hp. In a first for Saab, the engine is paired up with the next-generation GM Hybrid system which we'll have more about tomorrow. Efficiency is further enhanced by solar power and active aerodynamics. A photovoltaic panel embedded in the roof provides extra charging capability for the hybrid battery.
Aerodynamics on small cars is always tricky as the airflow falls off the trailing edge of the roof. The 9-X tries to address this with active aerodynamics. A spoiler that wraps over the rearmost pillar and roof extends backwards when speeds get over 70km/h. The effect is further enhanced by a diffuser that comes out below the rear bumper. The two components increase the effective length of the car and help improve the airflow off the rear. The 9-X can accelerate from 0-100kph in 7.9 sec on E85 and 8.3 sec on gasoline. Carbon dioxide emissions come in at a low 105g/km on ethanol and 117g/km on gasoline. Fuel efficiency is 36.8mpg (US) on biofuels while each gallon of gasoline will take the 9-X 48 miles.
