A CNG Bi-Fueled 2015 Impala, Silverado and Sierra
An all-new and award winning design that will soon be available with a Bi-fuel option. Earlier today GM announced it will sell a Chevrolet Impala sedan that operates on either gasoline or compressed natural gas (CNG). Besides the very expensive and apparently soon to be discontinued 2012 Honda Civic Natural Gas, the 2015 Chevrolet Impala will be the only bi-fuel OEM sedan available in North America. The Chevrolet Impala bi-fuel sedan features a factory-engineered and fully warranted powertrain that switches seamlessly from CNG to gasoline with an expected range up to 500 miles.
