Press Release
General Motors will build a Chevrolet Impala sedan for retail and fleet customers that operates on either gasoline or compressed natural gas (CNG), GM Chairman and CEO Dan Akerson announced today.
It is the only manufacturer-produced full-size bi-fuel sedan and expected to go on sale next summer as a 2015 model. Akerson announced the car during remarks at an energy summit marking the 40th anniversary of the OPEC Oil Embargo.
“OPEC Oil Embargo + 40: A National Summit on Energy Security,” was sponsored by the nonpartisan group Securing America’s Future Energy, or SAFE. Prominent political, business and military leaders assessed the current state of America’s oil dependence since the 1973 oil embargo
Akerson said the bi-fuel Impala is an example of using affordable technology to reduce oil consumption and save consumers money at the pump.
“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 a cleaner-burning transportation fuel compared to petroleum products, and costs significantly less than gasoline at current prices. CNG vehicles typically have 20 percent fewer greenhouse gas emissions than gasoline-powered cars, according to the California Air Resources Board.
The Chevrolet Impala bi-fuel sedan addresses the range anxiety issue associated with vehicles that run only on natural gas, Akerson said. It features a factory-engineered and fully warranted powertrain that switches seamlessly from CNG to gasoline. Total range is expected to be up to 500 miles.
Akerson said that in addition to advanced technologies and alternative fuels, achieving energy security will require productive partnerships between energy companies, utilities, environmental groups, labor unions, universities and manufacturers.
GM, he said, is working closely with 14 of the country’s largest unions and environmental groups through the Blue-Green Alliance, and has relationships with regulators that are “more constructive than ever.”
Akerson also reiterated a call he made earlier this year for the Administration and Congress to create a new, consumer-driven national energy policy from a position of strength and abundance.
For its part, GM is committed to saving 12 billion gallons of gasoline in its 2011 to 2017 model year vehicles – offsetting nearly a year of crude imports from the Persian Gulf – with technologies that include lighter materials to reduce vehicle mass, alternative fuels, clean diesel and electrification.
In addition to the Chevrolet Volt, Chevrolet Spark EV and the upcoming Cadillac ELR, GM is introducing start-stop technology standard on the 2014 Chevrolet Malibu helping the midsize sedan achieve 25 mpg city/36 mpg highway, and using electrification to boost fuel economy in the Buick Regal and LaCrosse sedans, which both get EPA-estimated 36 mpg hwy.

The 2015 bi-fuel Impala is fitted at the factory with a port fuel-injected 3.6L engine that includes hardened intake and exhaust valves and valve seats, to support the long-term durability needed for CNG combustion. -
An overlay of the CNG system shows key components including the engine and gaseous fuel storage fuel storage and delivery system, which was developed and validated by GM engineers, and backed by GM new vehicle and powertrain limited warranties. -
While EPA estimates on the 2015 bi-fuel Chevrolet Impala are not yet finalized, an approximately eight gasoline-gallon-equivalent CNG tank mounted in the Impala’s trunk is expected to provide up to 150 miles of vehicle range for a total range of up to 500 miles. -

Compressed natural gas is less costly at the pump and significantly reduces carbon dioxide emissions compared to traditional liquid fuels such as gasoline. A person who drives 24,000 miles a year, in the bi-fuel Chevrolet Impala, can recoup the additional investment in the bi-fuel option within a few years at current prices. -
The 2015 Chevrolet Impala bi-fuel sedan, expected to go on sale next summer, is the only original equipment manufacturer-produced full-size sedan in North America capable of running on either cleaner-burning, mostly domestically produced compressed natural gas (CNG) or gasoline. -
The 2015 Chevrolet Impala bi-fuel sedan joins Chevrolet’s growing range of manufacturer-engineered and validated CNG vehicles. -

A separate CNG fuel tank, mounted in the trunk, enables the driver to switch between fuels at the push of a button when driving the 2015 bi-fuel CNG Impala. When the CNG tank is depleted, the system automatically switches to gasoline.
