The first 2014 F-150 with the ability to run on compressed natural gas (CNG) rolled off automaker’s Kansas City assembly line, according to the Ford Motor Company.

The 2014 Ford F-150 with 3.7-liter V6 engine is available with a factory-installed, gaseous-fuel prep package that includes hardened valves, valve seats, and pistons and rings so it can operate on either natural gas or gasoline through separate fuel systems.

When equipped with a bi-fuel CNG/LPG engine package, the 3.7-liter V6 F-150 is capable of achieving more than 750 miles on combined tanks of gasoline and CNG, depending on the tank sizes selected, according to the automaker. The Ford F-150 with 3.7-liter V6 has an EPA-estimated rating of 23 mpg on the highway and 19 mpg combined.

"Businesses and fleet customers have been asking Ford to make F-150 available with CNG capability to take advantage of the fuel's low price and clean emissions," said Jon Coleman, Ford fleet sustainability and technology manager.

CNG/LPG engine prep from the factory costs $315 before the customer 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 fuel tank capacity.

CNG conversions can provide stability against fluctuating fuel prices as well as lower vehicle operating costs for fleet administrators, according to Ford. CNG sells for an average of $2.10 per gasoline gallon equivalent, and is as low as $1 in some parts of the country, representing a significant savings over unleaded regular fuel. The national average for unleaded regular fuel is $3.29 per gallon.

According to Ford, customers also can accelerate the payback period by taking advantage of a growing number of state incentives. Nearly 20 states – including Oklahoma, Texas, Pennsylvania and Florida – offer or soon will provide tax incentives or rebates for CNG-converted vehicles. In Florida, fleet customers will be eligible for rebates of up to $25,000 beginning in 2014.

By summer 2014, Ford will offer eight commercial vehicles with a gaseous-prep option, a number no other full-line manufacturer can match:

• Transit Connect van and wagon.

• Transit van, wagon, cutaway and chassis cab.

• E-Series van, wagon, cutaway and stripped chassis.
