GM Chairman and CEO Dan Akerson officially unveiled the General Motors Chevrolet Impala sedan for retail and fleet customers that can be fueled with either gasoline or compressed natural gas (CNG).

The new variant is scheduled to reach dealerships next summer as a 2015 model, and the Impala CNG will be the only full-size bi-fuel sedan available on the U.S. market. Akerson said the new bi-fuel Impala is a good example of using a rather affordable technology to decrease fuel and oil consumption and also save money at the pump for buyers.

“We know that U.S. energy security won’t come from a one-off moonshot, ” Akerson said. “It will flow from our systematic investment in technology and innovation… our drive to get more from existing energy sources and renewables… our commitment to conservation… and it will be assured by fully and safely exploiting our shale gas reserves.”

Natural gas is known to be a cleaner-burning fuel when compared to the traditional petroleum offerings, while also available at a fraction of the costs associated with gasoline at current prices. CNG vehicles usually make due with 20 % lower greenhouse gas emissions than conventional, gasoline-powered cars, according to the California Air Resources Board. The Chevrolet Impala bi-fuel sedan also features a factory-engineered and fully warranted powertrain that switches seamlessly from CNG to gasoline. Total range is forecasted to be around 500 miles.
