General Motors has delivered about 200 of its 2015 Chevrolet Bi-Fuel Impala sedans powered by compressed natural gas (CNG) to fleet customers following a delay to ensure quality.
The vehicle, which can run on gasoline or CNG, has been delivered mostly to commercial and fleet customers, reports the Detroit News. GM is offering the vehicle in the 2FL and 3LT trim levels.
The CNG Impala uses a bi-fuel system that includes a 3.6L V-6 engine that produces 232 hp and 218 lb.-ft. of torque in CNG mode and 258 hp and 244 lb.-ft. of torque in gasoline mode. The engine delivers power through a 6-speed automatic transmission to the front-wheel-drive powertrain.
The vehicle provides an estimated range of 150 miles on CNG and 350 miles on gasoline, giving it a nearly 500-mile combined range.
The CNG fuel system is covered by two GM warranties, including a three-year or 36,000-mile bumper-to-bumper and five-year or 100,000-mile powertrain and emission control system limited warranties, according to a sales sheet.
The vehicle uses a Type 1 steel CNG tank that's horizontally positioned in the trunk behind the rear seat back. The tank has a capacity of the equivalent of 7.8 gallons of gasoline.
The vehicle meets emissions certification requirements from the U.S. Environmental Protection Agency and California Air Resources Board, according to GM.
