LIVONIA, MI – Roush has introduced the first dedicated propane-powered F-150 pickup truck using an advanced liquid propane injection (LPI) system. The Roush F-150 LPI is designed and manufactured to operate solely on propane while providing the same horsepower, torque, and drivability of an F-150 equipped with a gasoline-powered 5.4L, 3-valve Triton V-8 engine. Roush will begin taking orders for the propane-powered F-150 immediately. The truck can be ordered, delivered, and serviced through a nationwide network of select Ford dealers. Offered as a 2007.5 model-year vehicle, it is the only propane-powered light-duty truck available from an original equipment manufacturer this year. The Roush F-150 is available in Regular Cab, SuperCab, and SuperCrew cab styles with XL or XLT trim and the full range of bed lengths. The LPI option includes dedicated propane fuel lines, fuel rail assembly, and fuel tank. Additionally, the vehicle’s OEM computer has been re-calibrated to provide optimum performance and fuel economy. The base LPI option is $6,500 and includes a unique 20 gallon toroidal fuel tank, mounted in place of the underbody spare tire. For customers in need of increased range, a 50 gallon, in-bed fuel tank is available as an additional option. Vehicle start is controlled by a “one-touch” system, where the engine controls take over from the driver to provide the fastest possible start with the lowest emissions. The OEM engine control is used with unique calibration values to suit the changes in properties from gasoline to propane. The maintenance schedule for the Roush F-150 LPI is similar to that of a gasoline engine schedule with no special oils or change intervals required.
