IMPCO Automotive has been awarded General Motors' bi-fuel compressed natural gas (CNG) cab chassis program for the 2016, 2017, and 2018 model years, the alternative fuel system supplier announced.

The new cab chassis program expands IMPCO Automotive's existing bi-fuel CNG vehicle programs for GM, which include Chevrolet Silverado 2500HD and GMC Sierra 2500HD pickups with multiple cab and bed configurations, and dedicated CNG full-size Chevrolet Express and GMC Savana vans, according to IMPCO.

As an extension of GM's manufacturing process, IMPCO Automotive installs the bi-fuel CNG fuel systems using OEM processes and standards. All of the CNG fuel systems are warranted and validated by General Motors.

Bi-fuel vehicles enable fleet operators to reduce emissions using CNG, which burns cleaner and costs less than gasoline. The 24.5-gallon CNG tank, in addition to the 23.5-gallon gasoline tank, on the Silverado 3500HD provides fueling flexibility and optimal range between fill-ups, IMPCO said.

OEM conversion of the vehicles will be done at IMPCO Automotive's manufacturing facility in Union City, Ind., with ship to commerce (STC) approval from GM expected to coincide with the gasoline vehicle's release for the 2016 model year.
