Saturn Flextreme Concept Hybrid targets 444 mile range

General Motors like so many other automakers have a number of concept vehicles that all have one thing in common, and that’s that they are fuel-efficient hybrids. According to CNN, GM’s latest offering is the Saturn Flextreme, and should be a huge hit with the Americans is the car goes into production, as the U.S. consumer are starting to think about the environment.

General Motors are aiming for an estimated driving range of 444 miles from the Saturn Flextreme, and hope that this hybrid could go into production by 2010-2011. The Saturn Flextreme will use batteries to charge an electric motor and also a 1.3 liter, three cylinder low-sulfur turbo charged diesel engine.

If you was to use just the electric motor, then the vehicle will have a range of just 34 miles, then the diesel engine will kick in to power the car while charging the batteries up. GM says that many people who travel a short distance to work will not need to use the diesel engine, and they can charge the batteries when they get home.
