Going against popular perception, diesel vehicles are showing some pretty good pickup. The context, of course, is US sales of oil-burners. And those sales are on the rise as more Americans look to cut refueling costs via more fuel-efficient vehicles.
 
 US clean-diesel sales through June have jumped 25 percent from a year earlier, outpacing the 4.2 percent increase of total vehicle sales, says Diesel Technology Forum, citing research from HybridCars.com and Baum & Associates. In fact, diesels, which account for about three percent of US vehicle sales now, may double that marketshare by 2018, as more Americans are attracted to a powertrain that on average delivers about 30 percent better fuel economy than similar gas-powered engines. In all, there are 46 diesel models in the US, including 27 cars and SUVs, so it’s not just all about big torquey rumbling pickup trucks anymore.
