Hybrid Cars mileage ratings get a dose of reality

Cool - people who have hybrid cars always trumpet their high gas mileage but those 50's and 60's numbers do not reflect real-world use and are having to be revised by the EPA. From Wired comes this little jolt of reality:
Hybrid Cars' Fantasy Mileage Ratings Drive Into the Sunset
Hybrid car economics will face a new road test this month with the arrival of fresh models sporting revised mileage ratings from the Environmental Protection Agency.

This year, new test standards have forced manufacturers to lower advertised efficiency claims on most models compared to previous years, and car lots are bracing for a tougher environment for hybrid sales.

It will "make for an interesting summer," said Phil Reed, the fuel economy guide editor at auto website Edmunds.com. The estimations are based on data from Edmunds.com that assumes 15,000 miles driven per year and gasoline at an average price of $2.70.

Hybrids can cost from $1,500 to $4,500 more than their gas-only equivalents. The new mileage estimates mean it will take longer to recoup that extra cost in money saved on gas. Experts say the shift could dampen demand, although some hybrids will look better on paper than others.

According to a formula devised by Edmunds, it would take nearly 10 years to recoup the extra costs after buying a 2007 Mercury Mariner Hybrid, up from 6.6 according to the old mileage ratings. For the 2007 Honda Accord and Honda Civic hybrids it takes 14.5 and 6.5 years, respectively.
The article is just looking at gas mileage -- they are not looking at the environmental damage from manufacturing all of those batteries and the subsequent cost of disposal. Posted by DaveH at May 14, 2007 7:40 PM
