Are hybrid cars an answer?

I'm sure they are – to some questions. However, they may not be the answer to increasing fuel economy.

Hybrids, which typically claim to get 32 to 60 miles per gallon, ended up delivering an average of 19 miles per gallon less than their EPA ratings under real-world driving conditions (which reflect more stop-and-go traffic and Americans' penchant for heavy accelerating) according to a Consumer Reports investigation in October 2005.

HYBRIDS ARE ALSO failing to pay for themselves in gas savings. A study by the car-buying website Edmunds.com calculates gasoline would have to cost $5.60 a gallon over five years for a Ford Escape hybrid to break even with the costs of driving a non-hybrid vehicle. The break-even number was $9.60 a gallon for a Honda Civic hybrid.

If people aren't buying fuel economy, what are they buying?

Then there's the ultimate defense: They are just like conventional cars because drivers buy them for many reasons other than fuel savings and cost. There's the "prestige of owning such a vehicle," says Dave Hermance, an executive engineer for environmental engineering at Toyota, the leading seller of hybrids. After all, many vehicle purchases are emotional decisions, he says.
