General Motors had been playing coy with the new output figures of the new 3.0L Duramax LM2 turbo-diesel, but a reader noticed the engine’s horsepower and torque figures listed on GMC’s website and sent a screenshot, unearthing GM’s well-kept secret.
These figures make the Duramax-equipped 2019 Chevrolet Silverado and 2019 GMC Sierra the most powerful half-ton diesel trucks on the market. The 2019 Ford F-150’s 3.0 liter diesel makes 250 horsepower and 440 pound-feet of torque. Fiat Chrysler has not announced the EcoDiesel engine for the new Ram 1500 yet, but if the engine does return in the truck, it will probably make the same amount of power it did before – 260 horsepower and 442 pound-feet of torque.
GM will begin taking orders for the 2019 Chevrolet Silverado and 2019 GMC Sierra with the 3.0 Duramax LM2 engine in the near future, with deliveries expected to commence in the summer. The diesel is the last variant of the trucks to arrive. Crew Cab models with V8 engines were first to go sale in the third quarter of last year, while Regular Cab and Double Cab models with the 4.3L V6 LV3 and turbo-charged 2.7-liter I-4 L3B engines were launched in the fourth quarter.
GM wanted to offer customers more variety with its new generation of pickups – particularly with the mass market and more affordable Silverado. It offers eight trim levels and six engine/transmission combinations for the truck, with Silverado chief engineer Tim Asoklis saying the automaker placed a “major focus,” on expanding the trucks range of choices for this next-gen model.
