US Diesels Sales Up, But Not for Long

Diesel engines are currently being fitted on GM and Chrysler lineups of vehicles, but it looks like traditional gasoline engines are becoming so fuel-efficient that the diesels won’t make any sense.

Gasoline engines have improved a lot in the last 10 years, closing the gap between them and the diesels. While GM and Chrysler joined European brands by offering more diesels, Ford, Toyota and Hyundai are increasing fuel-efficiency for their gas engines and hybrids.

"There's no doubt the advancement in gasoline technology has improved and that has, in some respect, slowed down diesel options from OEMs," Tony Schultz, vice president of the Americas for technology supplier Honeywell International Inc.'s Turbo Technologies, said in a telephone interview.

Last year, diesel sales in US rose 25 percent, but per total industry sales, they represent only 2.7 percent of new-car purchases.

At least for passenger cars, the diesel engine is not that great deal like it was 10 years ago any more. They are expensive, no longer have the advantage in pulling power and they don't deliver significantly better fuel economy. Also diesel fuel in US costs about 36 cents a gallon more than regular unleaded.
