Chevrolet’s future is electrical, however the blue-collar model isn’t giving up on combustion energy fairly but. As a part of the introduction of the 2023 Silverado ZR2 Bison, Chevy buried an replace in regards to the Silverado’s glorious diesel powerplant.
Beginning with the 2023 mannequin yr, the three.0-liter turbodiesel straight-six packs 305 horsepower and 495 pound-feet of torque, up from 277 hp and 460 lb-ft within the present truck. Chevy made the enhancements with all of the nitty-gritty, oil-covered components that make ICE engines go. There’s a retuned turbocharger, upgraded gas injectors, and new metal pistons with an up to date combustion bowl. Chevy hasn’t introduced any adjustments in gas economic system but – the present truck returns 22 miles per gallon metropolis, 26 freeway, and 24 combined with four-wheel drive.
As with the present diesel-powered vans, a 10-speed computerized is the lone transmission alternative. The revised diesel is obtainable on the Customized Path Boss, LT, RST, LT Path Boss, LTZ, or Excessive Nation trim, however not the Silverado ZR2 or ZR2 Bison. That’s each disappointing (as a result of the Colorado ZR2 carried an optionally available Duramax) and bizarre (as a result of Chevy paired this announcement whereas introducing the stronger Silverado ZR2 variant).
Whereas the Motor1.com group hasn’t sampled Chevy’s Duramax straight-six in just a few years, it was a spotlight in our reviews of both the Silverado and Tahoe, in addition to the GMC Sierra. Robust and punchy from a standstill, the engine pace climbs in a clean and predictable manner, with little letup within the efficiency. The throttle is great, with a pleasing weight that makes modulation a cinch. And the 10-speed is, as with the 6.2-liter, a incredible associate for the engine. The turbodiesel can also be whisper quiet at cruising pace.
Whereas Chevy is simply specializing in the Silverado, presumably the up to date model of this popular engine will make its method to the Tahoe/Suburban, in addition to to the GMC Sierra and Yukon and doubtlessly the Cadillac Escalade. Bowtie loyalists will be capable to buy a Silverado with the up to date engine later this yr, when it begins rolling out of GM’s Flint, Michigan engine plant.
