Spy photographers have spotted a 2019 Silverado 1500 test mule being topped off at a diesel pump, all but confirming that a new, diesel-burning Silverado light-duty will arrive in the not-too-distant future.
General Motors’ mid-size trucks – the Chevrolet Colorado and GMC Canyon – already have diesel engine options, as does the full-size Ram 1500 EcoDiesel from rival automaker Fiat-Chrysler. And with Ford now officially planning to introduce an oil-burning F-150 for 2019, it should come as no surprise that GM is working on a compression-ignition mill for its light-duty full-size pickup.
Specific details regarding the future Chevrolet Silverado‘s diesel engine are currently unknown. We can recall the 4.5-liter Duramax diesel V8 that never was – an engine intended for the light-duty Chevy Silverado and GMC Sierra last decade that was scrapped when the US economy tanked in 2009.
While we will continue to refute any rumors of the 4.5L coming back from the grave, such an engine would likely compare favorably against the 3.0-liter oil-burners used by the Ram 1500 EcoDiesel and 2018 Ford F-150. The 2.8-liter, four-cylinder diesel in the smaller 2017 Chevrolet Colorado and 2017 GMC Canyon, meanwhile, doesn’t seem a likely choice for GM’s heavier Silverado/Sierra.
In all actuality, it’s likely that GM has an entirely new diesel engine in development for its half-ton trucks. And while both the Ford and Ram champion 3.0L diesels, the displacement of an alleged GM half-ton diesel engine is still unknown.
