2012 Ram 2500 Heavy Duty CNG

2012 Ram 2500 Heavy Duty CNG with bi-fuel capability — powered by compressed natural gas or gasoline.

Ram Truck will become the only manufacturer in North America to offer a factory-built compressed natural gas-powered (CNG) truck.  The Ram 2500 Heavy Duty CNG pickup is designed for fleet and commercial customers, and offers cost and emissions benefits, using an abundant, domestically sourced fuel.

A look inside the 2012 Ram HD CNG.

The Ram HD CNG is powered by the 5.7-litre HEMI® V8 and features both compressed gas storage tanks and a 30L gasoline fuel tank.

The Ram’s 5.7-litre HEMI bi-fuel engine has been modified to run on compressed natural gas as well as gasoline. Redesigned heads with specifically designed CNG compatible valves and valve-seat materials allow the engine to burn both fuels. It also gets a second, CNG-specific fuel rail and set of injectors. New spark plugs improve combustion and durability, and a new powertrain control module allows the HEMI to operate on either of the two fuel sources. Canadian customers can opt for a 132-litre (35-gallon) gasoline tank (late availability).

Although a small amount of gasoline is used during engine startup, the Ram CNG runs exclusively on compressed natural gas. If the CNG tanks are emptied, the vehicle will automatically switch to gasoline.

The 2012 Ram 2500 Heavy Duty CNG keeps its strength.

The Ram 2500 CNG retains its heavy-duty capability: competent towing, payload hauling and outstanding acceleration for highway merging and passing.  It offers up to 1,580 lb of payload, 4-ft.-8-in. usable bed length and up to 7,650 lb of towing capability when properly equipped.  Like every Ram 2500 Heavy Duty model, the 2012 Ram CNG’s brake system reflects distinctive advantages, with huge, oversize 14-inch rotors and calipers to match. Front GAWR is rated up to 5,200 lb — ideal for snow plow attachments.


Clean Energy

CNG comes primarily from underground sources in Canada and the United States.  It is plentiful and offers lower tailpipe greenhouse gas emissions than gasoline or diesel fuel. In fact, CNG vehicles emit 20 per cent less CO2 than gasoline vehicles – and benefit the environment not only by lowering tailpipe emissions, but also generating fewer greenhouse gasses in fuel production.   CNG is a mature technology that’s available at a lower cost than other alternative fuels. It’s further supported by positive consumer attitudes regarding green products and favourable governmental regulations and policy initiatives.  CNG technology is a viable near-term option to lessen transportation system dependence on crude oil.

The company is currently taking fleet orders and expects to deliver the first vehicles in July 2012
