The California Air Resources Board (CARB) has given its seal of approval for propane-powered Ford E-450 cutaway vans upfitted by Roush CleanTech.

Those cutaway chassis are now certified for sale in all 50 states, having received both Environmental Protection Agency (EPA) and CARB certification, with the conversions partly funded by the Propane Education & Research Council, the company noted.

Marquez & Marquex Foods, a South Gate, CA, manufacturer and deliverer of corn chips and snacks, will take delivery of the first Roush propane powered E-450s, with AvcoGas Propane Sales and Service, a Roush-certified propane autogas conversion center, delivering those vehicles.

“The Ford E-450 cutaway liquid propane autogas fuel system is a perfect example of a clean, green, EPA- and CARB-certified solution for airport shuttles, delivery vehicles, and buses,” said Todd Mouw, vp-sales and marketing at Roush CleanTech. “This vehicle also will help public and private fleets in their efforts at diesel displacement.”

Roush’s fuel system is available on 2010 and 2011 model year vehicles with a 158-in. or 176-in. wheelbase and equipped with a 6.8 liter V10 engine.
