GM’s E-flex system enables multiple propulsion systems to fit into a common chassis, using electric drive to help the world diversify energy sources and establish electricity from the grid as one of those sources.

The Chevrolet Volt is just the first variant of the E-flex System. The Volt uses a large battery and a small, 1L turbocharged gasoline engine to produce enough electricity to go up to 1,024 km’s. Future concepts might incorporate diesel generators, bio-diesel and
E-100.

The second variant of the E-Flex system uses GM’s new fifth-generation fuel cell propulsion technology and lithium-ion battery to provide up to 483 kms (300 miles) of petroleum- and emissions-free electric driving. The fuel cell E-Flex is a true Zero Emission Vehicle (ZEV) and operated all-electric from both hydrogen fuel cell-generated electricity and grid electricity. It is a plug-in capable, adding up to 34 additional kms (20 miles) each time it is charged, further reducing trips to the refuelling station.
