#GmDiesel

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.”

Moreover, Nicholson says of the tens of thousands of former Volkswagen TDI owners, “We don’t think those customers went away.”

We drove in and around the city in a 2017 GMC Canyon Duramax Diesel for 120 miles, then took a 180-mile journey to Prince Edward Island, and have since driven around that island 120 miles.

The result: 30.2 miles per gallon on the U.S. scale, a miserly 7.8 litres per 100 kilometres. It doesn’t hurt that, around these parts at the moment, diesel costs roughly $0.25 USD less per gallon versus regular.

The 2.8-liter four-cylinder under the hood of this GMC Canyon, with a paltry 181 horsepower but a stump-pulling 369 lb-ft of torque at just 2,000 rpm, is one of a handful of diesels General Motors has installed in U.S. market vehicles. The 6.6-liter Duramax V8 in heavy-duty pickup trucks is the one you hear rumble most often. But GM is also inserting the Cruze’s 240-lb-ft 1.6-liter turbodiesel into the third-gen Chevrolet Equinox and second-gen GMC Terrain.

With diesel engine offerings in two pickup truck lines, a compact car, and a pair of small SUVs, can General Motors — not Mazda, not Mercedes-Benz, not Skoda — be the North American diesel-lover’s answer now that Volkswagen committed its unclean diesel transgressions?

Volkswagen’s emissions scandal may have killed that company’s diesel presence in North America, but it didn’t kill demand for diesel engines in general — especially ones that don’t pollute like Chernobyl and end up in the trash heap.

At least, that’s General Motors’ take on it. The automaker hopes to fill the void created by VW’s oil-burning absence and, in doing so, score some points with the EPA. With diesel engines now available in five vehicles you won’t see on a worksite (and five more that you would), GM has high hopes it can erase memories of its 1980s diesel woes.

Ah, the disastrous GM diesel V-8 cars of the 1978-85 model years, equipped with failure-prone engines that scared generations of Americans away from diesel cars. Nowadays, of course, diesels work just fine (except when they don’t), but it’s good to see the occasional reminder of these miserable GM cars in the junkyard as part of our American automotive heritage. Only problem is, just about all of these cars were crushed or had gasoline-engine swaps decades ago (I recall helping my uncle drop a Chevy 307 into a very clean Olds 88, around 1988 or so).

Here’s an extremely rare example that I found in a San Francisco Bay Area self-service yard last week.
