Fuel Economy Drives New Interest in Diesel Cars

CHICAGO, Aug. 19, 2006 — -- Chris Hynes' new diesel car has passed a crucial road test.

"The car is paying for itself," he says. "I believe the money I am saving in the fuel is going toward the payments for the car."

Hynes now spends $200 less per month on fuel -- and gets 30 more miles per gallon than he did with the gas pickup he traded in last year.

That kind of fuel economy -- 30 percent better than comparable gas vehicles -- is renewing interest in diesel cars. At Pugi Volkswagen near Chicago, demand has tripled.

"Anybody and everybody is looking at diesels now," says Chris Willuweit, of the VW dealership.

That's why automakers, from Detroit to Tokyo, are now putting diesel production in the fast lane -- from SUVs and pickups, to luxury and mid-size cars.

"Currently about 3½ percent of all new vehicles sold are diesels," says Anthony Pratt of JD Power and Associates. "By 2015, we expect that to grow to 12 percent."

Americans have been down this road before. At the height of the 1970s oil crisis, automakers rushed a slew of smelly and noisy diesels onto the market.

Since then, engineers like Don Hillebrand have spent thousands of hours trying to clean up diesel's dirty reputation.

"Literally, they're 98 percent cleaner," says Hillebrand, transportation research director for the non-profit Argonne National Laboratory. "I mean, what used to be a bucket of emissions is now a drop."

But that's still not clean enough in five states, including California and New York, where even the new diesels don't meet emissions standards -- though automakers are aiming for compliance by the end of the decade.

Some say it's a waste of time and money.
