General Motors claims that its 2015 Chevrolet Bi-fuel Impala running on gasoline or CNG (compressed natural gas) will be the only bi-fuel-capable sedan on the market to offer a factory warranty. It is slated to go on sale later this year at a starting price of $38,210. The CNG tank mounted in the trunk has the equivalent capacity of 7.8 gal (30 L) of gasoline, which is expected to offer approximately 150 mi (240 km) city range on CNG based on GM testing. With gasoline and CNG combined, expected range is 500 mi (800 km) city based on GM testing. U.S. EPA estimates are not yet available. Impala’s bi-fuel system seamlessly switches to gasoline power when the CNG tank is depleted. Drivers who wish to change fuels while driving can do so by simply pushing a button. A light on the instrument panel indicates when CNG is being used, and there is no interruption in the vehicle’s performance.

In preparing to launch the 2015 Bi-fuel Impala, GM reached out to quasar to raise public awareness on the possibilities of renewable CNG. About 50% of quasar's fleet are GM vehicles—most of which run on CNG.
