Spied: 2019 Chevrolet Silverado 1500 caught at a diesel pump

This is the first solid confirmation of an oil-burning Silverado 1500.

Spy photographers caught a 2019 Chevrolet Silverado 1500 fueling up at a diesel pump, giving us our first solid confirmation that a light-duty diesel model is on the way.

General Motors has been looking seriously at diesel for its 1500-series full-size pickups, but various hurdles have prevented the projects from seeing daylight. It appears those obstacles have been cleared.

What we're not certain of yet is exactly which engine GM has under the hood of this development vehicle. GM's midsize Canyon and Colorado employ a 2.8L four-cylinder diesel which, while grunty, doesn't exactly make those trucks feel quick. It would likely be outmatched by the weight of a full-sized truck, even if it is being built with weight-saving materials.

A 4.5-liter diesel V8 was under development prior to the 2009 financial crisis and was "shelved." Depending on how complete that program was, it may be the most logical choice in terms of development costs.

If it would be too expensive to resurrect and GM found itself compelled to start from scratch, a three-liter unit would compete directly with the Ram 1500 EcoDiesel and Ford's forthcoming oil-burning F-150.

We expect a diesel-powered Silverado 1500 will lag the truck's formal introduction by at least a few months, if not a full model year, so it may be some time before we learn any specifics.
