A company located in the heart of corn country has developed what it calls the first bolt-on kit that safely and easily converts the most common fleet vehicles to ethanol, and it could offer kits for more popular cars and trucks by the end of next year.
The Flex-Box Smart Kit from Flex Fuel U.S. allows fleet operators to fill their vehicles with gasoline or any blend of ethanol. The kit is certified by the Environmental Protection Agency, meaning it meets all emissions regulations and won't void the manufacturer's warranty.
So far it only works on the Ford Crown Victoria, Mercury Grand Marquis and Lincoln Town Car. Flex Fuel says it started with those models because they are the most common passenger vehicles used in police, taxi and municipal fleets.
"Many government, city, state and federal and chauffeured fleets are major oil consumers, so our goal is to help this country save taxpayers money, wean itself off foreign oil and support our local farmers and help reduce greenhouse gas emissions," said Chris Disher, the company's chief financial officer.
While automakers offer a wide variety of flex fuel vehicles and about 6 million vehicles on the road can burn E85, the Flex-Box Smart Kit allows older cars to be retrofitted. It works with existing fuel tanks, fuel injectors and other equipment, and a computer mounted under the hood continuously monitors the engine management and emissions systems to deliver supplemental fuel injection as needed.
Flex Fuel spent more than a year developing the system and said EPA tests a vehicle with the Flex-Box under the hood returned 16.9 mpg in the city and 26.8 mpg on the highway. The Chicago-based company says the system brings a 15 percent reduction in fuel costs - nationwide, E85 is 58 cents a gallon cheaper than gasoline - and an 85 drop reduction in greenhouse gas emissions.
