Roush CleanTech and Green Alternative Systems revealed the new Ford F-550 chassis cab powered by propane autogas at the NTEA Work Truck Show.

With more than 65 usable gallons, this vehicle offers the longest driving range of any dedicated alternative fuel counterpart on the market. The fuel tank sits between the frame rails and behind the aft axle.

Customizable to carry up to 33 passengers as a shuttle, the Ford F-550 also suits the delivery, construction, transit and utility markets. Equipped with a 6.8-liter, V-10 engine, the propane autogas alternative fuel system is available beginning with 2013 model year vehicles or newer.

GAS, a certified Ford Qualified Vehicle Modifier installer, designs mounting hardware, handles packaging strategy and integrates Roush CleanTech propane autogas fuel system technology into the F-550 chassis cab. The vehicles maintain the factory Ford warranty and the same horsepower, torque and towing capacity as their gasoline counterparts.

Fleet professionals running propane autogas vehicles can expect to save at least 40% on the price of fuel and reduce greenhouse gas emissions by up to 25% compared to gasoline. When compared to diesel, propane autogas emits significantly fewer smog-producing hydrocarbons; eliminates particulate matter by virtually 10%; and, due to less carbon buildup, propane engines tend to last much longer than diesel engines.

Plus, propane autogas delivers the largest refueling network of any alternative fuel in the nation with thousands of public fueling stations located across the country.

The two companies previously announced the GAS F-59 propane autogas fueling system by Roush for the Ford F-59 and F-53 stripped chassis. Each of these platforms is available for order through GAS, with production and delivery starting in late May 2013.
