The approval is valid for the 2010 Ford F-250 and F-350 models with the 5.4L V8 engine. Roush is currently working towards receiving this same CARB certification for the upcoming 2011 propane-powered Ford E-150, E-250 and E-350 passenger and cargo vans launching in the second quarter of 2010.
"We have made a significant investment in our liquid-propane injection technology, and we look forward to helping fleet operators across the country reduce their carbon footprint and operating costs with our propane-powered vehicles," said Todd Mouw, director of sales and marketing for Roush Propane Vehicles. "We have more than two hundred 2010 Ford F-250s and F-350s in our inventory, so we have plenty of trucks available to meet customer demand."
Roush plans to covert the Ford E-Series vans to run on propane, as well as the Ford E-450 cutaway with the 6.8L V10 engine.
