General Motors’ diesel-powered midsize pickup trucks are the only midsize pickup trucks available in America with diesel engines. GM’s Chevrolet Cruze is the only compact car on sale in America with a diesel engine. Although the Mazda CX-5 is scheduled to arrive later this year, diesel-powered editions of the Chevrolet Equinox and GMC Terrain will be the first small utility vehicles with diesel options.

With all the negative diesel press earned largely by the eruption of Volkswagen’s emissions scandal in September 2015, is GM’s investment in America’s diesel market a complete and utter waste?

GM obviously thinks not. “I don’t think diesel customers forgot why they liked driving diesels in the last two years,” GM’s vice president for global propulsion systems, Dan Nicholson, tells Automobile. “They didn’t forget about the driving character or the fuel economy.”

Rising emissions regulations are forcing many automakers to adopt forced induction across the board. While some, like Mazda and Honda, have been milking naturally aspirated engines for all their worth, even they have turned to turbochargers to do some of the heavy lifting. General Motors has more than doubled North American sales of vehicles with turbo motors — going from roughly 288,000 units in 2011 to 712,000 in 2016, 23 percent of its total volume.

GM’s powertrain lineup has changed dramatically. A decade ago, only a handful of its models came with a turbo option, while just under half of today’s fleet uses some form of forced induction. The trend is set to continue for the 2018 model year, boosting the carmaker’s share of turbocharged offerings above the 50 percent mark. (Read More…)
