Keith Crain's June 24 column, "Higher MPG simply isn't that easy," expresses doubt that automakers can build cars and sport-utilities that are more fuel efficient.
He might show a little more faith in the industry.
The Chrysler group announced recently that it has used small engineering changes to produce a Dodge Durango SUV that when combined with several additional fuel-saving components has 25 percent greater fuel efficiency.
And Chrysler did it with no sacrifice in emissions, power, cost, weight or engine life.
This wasn't a revolutionary breakthrough; it was a simple combination of existing technology and basic American know-how. Other automakers could do the same.
Sierra Club is urging consumers to ask for the freedom options package, a set of existing fuel-saving components. Taken together, those technologies would put our cars and SUVs at 40 mpg. Go to www.sierraclub.org/freedom for more information.
Americans should be able to go into showrooms and ask for safe, affordable, comfortable, fuel-saving cars and SUVs. Sometimes it really is that simple.
