Scott Settlemeyer gives us a run down on all the ways that GM is helping to create a line up of fuel efficient to fuel free vehicles.  He explains the gas engine for the pickup/suvs can shut down 4 cylinders when they’re not needed.  He also talks about the Chevy Tahoe hybrid which gets better combined fuel economy than the Toyota Camry.

The first thing he explained when he got into the Volt was their reasoning for the battery range.  70% of people drive less than 40 miles per day which means that they can do their daily driving and then plug it in at night without using a drop of gas.  The Volt also has regenerative braking, so every time the brakes are used the car is recharging the batteries.  When the battery level gets too low a 1 liter 3 cylinder gas engine kicks in and drives an electric generator to recharge the batteries.
