Airport Shuttles Turn to ROUSH Propane Vans to Meet New Vehicle Restrictions

May 12, 2010

LIVONIA, MI - Phoenix Sky Harbor International Airport is among the first, but certainly not the last, airport in the country to require servicing fleets to run their vehicles on an alternative fuel. This has left companies scrambling to fulfill the new regulations, and many are looking to ROUSH propane-fueled E-Series vans to meet the requirements.

As part of a city-wide push to reduce pollution, Sky Harbor has adopted alternative fuel rules for taxis (including limos and shuttles) that have permits to pick up passengers at the airport. These vehicles must use an approved alternative fuel, one of which is liquid propane gas. The ROUSH liquid propane injection system works on the Ford E-150, E-250, and E-350 chassis with the 5.4L, V-8 engine. Each has been EPA certified, with CARB (California Air Resources Board) approval pending.

With the ROUSH propane system installed, there is no additional weight added to the vehicle as with some other alternative fuel options. This means that stopping distance and brake wear will be comparable to a gasoline vehicle, as well as cargo weight capabilities. Furthermore, there is no loss of horsepower or torque running on propane.

The propane tank is installed under the vehicle in the same location as the OEM gasoline tank so there is no loss cabin space for cargo or passengers. The 25-usable gallon fuel tank offers a range of approximately 300 miles. The fuel system is covered with a ROUSH 3-year/36,000 mile warranty; the Ford warranty covers the remainder of the van and engine when ordered with the gaseous prep package now offered.

Numerous studies have been conducted on the operational savings fleets can achieve by converting to propane as a motor fuel, and a savings calculator is available online at www.SwitchToPropane.com that allows the user to input variables specific to their usage. It is not uncommon for fleet managers to see savings of nearly $39,000 per van over a total vehicle life of 350,000 miles.
