The Roush team's latest effort is a new liquid propane powered Ford F-150. The Roush F-150 LPI is not a dual fuel vehicle but is instead set up to in the words of Hank Hill "run solely on clean-burning propane." According to Roush, the use of liquid propane port injection should provide increased starting, performance and reliability than previous propane conversions. The new truck maintains the same power and torque as the standard gasoline fueled 5.4L V-8. The F-150 will be available through select Ford dealers at a cost starting at $6,500 over the base price of the truck for a system with a 20 gallon tank mounted under the bed. An optional 50 gallon in-bed tank also available.
