The long-awaited fuel economy figures for the 2020 Chevrolet Silverado diesel have been released. As GM promised, its diesel-burning half-ton pickups will be class-leaders when it comes to fuel economy.
GM announced today the Environmental Protection Agency (EPA) have granted the 2020 Silverado ratings of 33 mpg highway and 23 mpg city when equipped with the new Duramax diesel engine and rear-wheel-drive. For those keeping score, those ratings give the Silverado an edge of 3 mpg highway over the F-150 PowerStroke Diesel and a staggering 6 mpg over the outgoing Ram EcoDiesel.
When equipped with four-wheel-drive the figures drop to 29 mpg highway and 23 mpg city.
Regardless of drivetrain, the Silverado and GMC Sierra Duramax models are equipped with an all-new 3.0-liter turbo-diesel inline-six. The engine generates 277 horsepower and 460 pound-feet of torque that flows through GM’s new 10-speed automatic transmission.
The Duramax is available on the LT, RST, LTZ and High Country trims. For the LTZ and High Country, tit is a $2,495 option, identical to that of the 6.2-liter V-8. For the LT and RST, it equates to a $3,890 increase over the base 2.7-liter turbo four-cylinder.
It is worth mentioning that Ram has confirmed plans to introduce its EcoDiesel V-6 engine into the new Ram 1500 for the 2020 model year, but has not yet disclosed fuel economy ratings. The Ram is expected to come close to the F-150 PowerStroke and now Silverado Duramax, perhaps even pass it.
