Chevy Says Natural-Gas Option on 2015 Heavy Duty Silverado Saves $2,000 in Fuel

With introduction of the the new 2015 Silverado heavy-duty models, Chevrolet expanded availability of bi-fuel, gasoline/compressed-natural-gas versions to include  2500HD and 3500HD trucks in all cab styles. 

With CNG currently priced about 62 percent less per gallon than gasoline, a work truck typically driven 26,000 miles a year can save more than $2,000 annually based on 75 percent CNG usage and comparable efficiency to gasoline.

A separate CNG fuel tank enables the driver to switch between fuels at the flip of a switch. When the CNG tank is depleted, the system automatically switches to gasoline. General Motors’ tier-one supplier installs the CNG fuel tank and complementing fuel system upgrades at a secondary location. Chevrolet dealers deliver the trucks as they would with any optional content. 

The CNG option is available on all Silverado 2500HD configurations and Silverado 3500HD models with single rear wheels. The 2500HD double cab and crew cab models are on sale now, with 2500HD regular cab and all 3500HD models going on sale in July.

  • 6.0L engine is rated 360 hp and 380 lb.-ft. of torque on gasoline, and 301 hp and 333 lb.-ft. of torque on CNG
  • Equipped with a 4.10 rear axle gear ratio, maximum conventional towing rating for the bi-fuel HDs is 13,000 lb. on gas or CNG
  • The added CNG tank extends Silverado HD bi-fuel models' total range to 650 miles
  • GM's five-year/100,000-mile power train limited warranty covers CNG fuel systems
