After a long delay, the 2015 Chevrolet Impala bi-fuel natural-gas sedan is finally reaching customers.
The car--which can run on either compressed natural gas (CNG) or gasoline--was first shown in October 2013.
General Motors originally said it would put the Impala bi-fuel on sale by summer 2014, but the first deliveries didn't take place until over a year after that.

The carmaker delayed delivery of the first 2015 Impala bi-fuel sedans due to quality concerns.
After building about 200 cars, it held deliveries until an unspecified quality issue was addressed.

It shares a 3.6-liter V-6 with other Impala models, but with hardened valves and valve seats for better durability when used with CNG.
On natural gas, the Impala has an EPA-rated range of 119 miles. It has a range of 487 miles on both natural gas and gasoline.

GM originally said it planned to sell 1,000 Impala bi-fuel sedans in the first year.
It plans to offer the model through 3,200 Chevy dealerships nationwide.
