General Motors announced Tuesday that the compressed natural gas (CNG) option, available this fall for Chevrolet Express and GMC Savana full-size vans, will be priced at $15,910 MSRP.

Pricing for the all-inclusive CNG option includes a dedicated CNG system ($14,590), a natural gas-capable Vortec 6.0L V-8 engine ($1,295) and HD trailering equipment ($265). A $240 credit for deleting the spare tire brings the package price to $15,910. 

The total cost of either a 2011 Chevrolet Express or 2011 GMC Savana Cargo model, which starts at $25,980 would be $41,890 with the CNG option.

The Chevrolet Express and GMC Savana full-size vans come equipped with hardened exhaust valves, and intake and exhaust valve seats for improved wear resistance and durability with gaseous fuel systems.

The vans will meet all Environmental Protection Agency and California Air Resources Board emission certification requirements, and will be fully compliant with applicable motor vehicle safety standards. Each CNG Chevrolet Express or GMC Savana van also will be covered by GM's three-year, 36,000-mile new vehicle limited warranty and five-year, 100,000-mile limited powertrain warranty.
