 Ethanol
The IndyCar Series, which has
been recognized for its technical leadership in automobile
racing, is now the motorsports leader in renewable and environmentally
responsible fuel produced in America.
The
IndyCar Series’ groundbreaking use 100 percent
fuel-grade ethanol in its Honda Indy V-8 engines will have
an impact on motorists for years. Ethanol, which can be manufactured
from a variety of homegrown grains, is biodegradable, renewable
and ecologically friendly.
The long-term message is clear: If 650-horsepower IndyCar Series
cars that cover the length of a football field in 1 second
can run safely and effectively on 100 percent fuel-grade ethanol,
so can your vehicle (either 90 percent gasoline/10 percent
ethanol blend or an E85 vehicle) with reduced emissions as
an add-on benefit.
