DETROIT - The fully integrated and dedicated compressed natural gas (CNG) option, available this fall for Chevrolet Express and GMC Savana full-size vans, will be priced at $15,910 MSRP, General Motors announced Aug. 31.

The all-inclusive CNG option for commercial customers includes a dedicated CNG system, a natural gas-capable Vortec 6.0L V-8 engine, and heavy-duty trailering equipment. Chevrolet and GMC are the only full-line vehicle brands to offer a "check-the-box" CNG option for vans, according to GM.

"Customers tell us coordinating the upfit for their CNG vehicles takes away valuable time that would be better used running their business," said Joyce Mattman, director of Commercial Product and Specialty Vehicles. "Our CNG vans come with a fully integrated CNG fuel system, a comprehensive warranty, emissions compliance, and strong dealer support."

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), as well as 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.

Powered by a Vortec 6.0L V-8 engine, 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 (EPA) and California Air Resources Board (CARB) 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.
