Ford Motor Co. announced that the state of Oklahoma and the city of Dallas have placed orders for CNG-capable Ford F-150 pickups. In all, Oklahoma will take delivery of 256 trucks while Dallas will purchase 65.

“For fleet customers in Oklahoma, Texas and other states, a CNG F-150 really makes sense,” said Jon Coleman, Ford fleet sales manager. “The fuel is more affordable and widely available, and it reduces greenhouse gases and pollutants that cause smog.”

The 2014 F-150 is available with a gaseous-fuel prep option for the 3.7-liter V6 that can run on CNG or liquefied petroleum gas. CNG/LPG engine prep from the factory costs $315. The customer then chooses a Ford Qualified Vehicle Modifier to supply fuel tanks, fuel lines and unique fuel injectors. Upfits run approximately $6,000 to $9,500, depending on tank capacity.

“I am excited about Oklahoma’s partnership with Ford Motor Company as we work to support energy efficiency, cost savings and the use of clean-burning American-made energy,” said Oklahoma Gov. Mary Fallin. “Ultimately, converting our state fleets to CNG will save millions in taxpayer dollars.”

The specially equipped bi-fuel F-150 model purchased by Oklahoma features two storage tanks – the regular factory gasoline reservoir and a supplementary CNG tank. Combined, this gives the light-duty truck a range of up to 750 miles, depending on the size of the tanks. The most common configuration allows fleet operators to go 450 miles on CNG alone and another 300 miles on regular gas.
