“GREEN” ROUSH® PROPANE F-150 LEAVES MINIMAL CARBON DIOXIDE
FOOTPRINT

LIVONIA, Mich. (March 27, 2008) - With so much talk these days about
reducing emissions, lowering one’s carbon footprint, and going
“green,” ROUSH® has created an excellent fleet option by
developing a Ford F-150 pickup powered by liquid propane. ROUSH has long
been considered as Detroit’s foremost Tier 1 advanced powertrain
engineering company.

According to research provided by the Propane Education & Research
Council (PERC), propane's emissions have lower carbon content than
gasoline, diesel, heavy fuel oil, and ethanol. Even when upstream
emissions - those released as a result of extracting and processing
energy - are factored into the equation, propane is still one of the
best fuel options from a greenhouse gas (GHG) perspective.

When fuel is burned at a 99 percent combustion rate, on-site emissions
estimates of the amount of carbon dioxide released per Btu heavily
favors liquid propane gas which releases only 62.7 kg CO2/million Btu^.
Ethanol, commonly known as E85, releases 66.6 kg^, and gasoline falls in
at 70.5 kg^. Diesel fuel is the worst of the group at 72.5 kg.^

The exhaust emitted from a properly maintained propane-fueled engine
contains virtually no toxic compounds. And because the boiling point is
44 degrees below zero Fahrenheit, propane vaporizes almost instantly
when released into the atmosphere. It degrades rapidly when exposed to
the light, and no contamination will result from spills or leaks.
Essentially, when released outside an enclosure, liquid propane can
cause no ill effects.

Additionally, propane does not have the contaminants of some other
fuels like diesel, and has less criteria pollutants across many
applications. Propane's portability, storability, and environmental
benefits also qualify it to serve the unique needs of several
applications, such as fueling a fleet of pickup trucks.

The ROUSH F-150 Liquid Propane Injection truck 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 5.4-liter, 3-valve Triton™ V-8 engine.

ROUSH has begun taking orders for the propane-powered F-150. The 2008
model year truck can be ordered, delivered and serviced through a
nationwide network of select Ford dealers.

The ROUSH F-150 is available in Regular Cab, SuperCab and SuperCrew cab
styles with XL, XLT, STX, & FX4 trim and all three different bed
lengths. The liquid propane injection system option includes dedicated
propane fuel lines, fuel rail assembly and fuel tank. Additionally, the
vehicle’s computer has been re-calibrated to provide optimum
performance and fuel economy.
