  • 2014 Ram 1500 EcoDiesel, Bear Mountain, May 2014

    With electric-car battery prices falling faster than predicted even five years ago, carmakers face tough and costly choices in choosing powertrains for the lineups in 2020 and after. Pressed by stiff carbon-emission reduction laws in Europe and heavy regulations to encourage electric cars in China, they must assess how much to invest in new internal-combustion engines. Added to that is the perilous position of diesels for passenger cars and light trucks in light of the VW diesel emission scandal and increasingly stiff public reaction against the technology.

    Jeep Wrangler Diesel already testing, before 2019 launch

    The iconic Jeep Wrangler is a tough vehicle to make fuel-efficient. Its separate frame and body add weight, and it has all the wind-cheating grace of a small municipal hospital. The Wrangler SUV only gets redesigned every 10 years or so, so each new generation is a big deal to Jeep fans. DON'T...

  • 2014 BMW 328d

    As numerous political probes over the years have famously shown, once investigators dig into the circumstances around an alleged crime, anything can happen. The September 2015 announcement by the EPA that VW Group engineers had admitted to deliberate cheating on U.S. emission tests of the company's "clean diesel' engines may prove to be another case in point. Even as Volkswagen, Audi, and Porsche continue to buy back or modify more than half a million diesel cars in the U.S., investigations into the German diesel deception are expanding in Europe.

    Combustion engines: high emissions from short commutes a huge challenge

    Drivers in the U.S. have longer commutes than those in Europe and Asia, on average. In the U.K., short commutes in vehicles with combustion engines—whether gasoline or diesel—pose particularly tough emission problems. That's because the exhaust aftertreatment systems have to warm up...

  • Nicolas Hulot, French minister of ecological transition, announces 2040 ban on vehicles with engines

    To most North Americans, the idea of banning all vehicles with internal-combustion engines seems unthinkable. Filling up with gasoline (or diesel) is as American as are dispersed low-density suburbs without mass transit, bike paths, or even sidewalks. Europeans, more of whom live in cities and most of whom have access to a more balanced set of transportation options, are sometimes more clear-eyed about such matters.

  • 2012 Volkswagen Passat TDI Six-Month Road Test

    Another small portion of Volkswagen's diesel scandal has been put to rest: the EPA announced its approval of modifications for 2012 through 2014 Passat TDI sedans.
