Diesel cars

  • 2017 Audi RS 7

    It has been nearly two years since Volkswagen came clean and admitted its "clean diesel" engines were actually quite dirty. In 2015, a VW engineer admitted the TDI diesel cars sold in the U.S. since 2009 were outfitted with "defeat device" software that let them pass emission tests, only to emit far more nitrogen oxides in real-world use. Two years is a long time to implement damage control, which has cost VW Group $25 billion to date—but the story is continuing to unfold.

    Attention, Shoppers: Infiniti QX56s, Diesels Are NOT Hybrids

    It will come as a horrible shock to the driver of the pale green Infiniti QX56, but the 2-ton-plus full-size sport utility vehicle is not actually a hybrid. Nor, for that matter, is a Volkswagen Passat TDI--though it at least has a diesel engine, which gives higher gas mileage than the QX56's...

    Green Advice: You Filled A Diesel Car With Gasoline; Now What?

  • Audi A3 TDI clean diesel - European model

    In Europe, roughly half of all passenger cars sold come with fuel-efficient diesel engines. But for a variety of reasons, passenger diesels haven't caught on in the States, though the number is climbing slowly. Audi, proud of its diesel engine technology--which, among other things, has won the prestrigious 24 Heures du Mans endurance race in the Audi R15 TDI--is forging ahead and plans to offer a diesel variant of every model it sells in the U.S. by 2015. Modern clean diesels usually deliver fuel economy one-third to one-fifth better than that of a gasoline engine of similar power. They're...

    Although Honda designed and sold the world's second hybrid-electric car, the 1999-2006 Insight, the company hasn't done nearly as well in hybrids as its larger rival Toyota.
