Diesel-powered cars finally are gaining some sales traction in the United States.
When automakers offer car models with a choice of a gasoline or diesel engine, a surprisingly high percentage of consumers are opting for diesel.
Earlier this year, an R.L. Polk survey of car registration data revealed that more than 49 percent of VW Jetta sedans and wagons sold in the United States are diesels. And it's not just Volkswagen that attracts diesel devotees. Some 30 percent of Audi Q7 buyers, 18 percent of Mercedes GL purchasers and 17 percent of BMW X5 xDrive buyers chose diesels.
To be sure, the German marques tend to attract tech-savvy buyers who can afford to pay extra for diesels, and non-German brands have yet to demonstrate any similar successes.
