As you may know, the 2015 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD pickups are available with a CNG option, allowing them to run on both gasoline and compressed natural gas.

GM has announced that the CNG option starts at $9,500 for the pickup trucks, while a similar package for the 2015 Chevrolet Express and GMC Savana cargo and passenger short-wheelbase vans starts from $10,825 for the three-tank system and $12,090 for the four-tank system.

The bi-fuel CNG option will be available on all 2015 Silverado and Sierra 2500HD and 3500HD single-rear-wheel models. The Express and Savana vans have fully dedicated CNG fuel systems – available in three- or four-tank models on cargo vans and exclusively with the three-tank design on passenger vans.

CNG versions of the Silverado and Sierra 2500HD double cab and crew cab and the full-size Express and Savana vans are on sale now. The Silverado and Sierra 2500HD regular cab and all 3500HD pickups go on sale in July.

“Based on current average fuel prices, CNG is more than a dollar cheaper than an equivalent gallon of gasoline, giving drivers and businesses an incentive to use CNG to power their vehicles,” said Ed Peper, U.S. vice president, GeneralMotors Fleet and Commercial.

GM warrants and validates the fuel systems on all of its CNG trucks, vans and the upcoming bi-fuel Chevrolet Impala sedan through its five-year/100,000-mile – whichever comes first – powertrain limited warranty.
