We tested the 2021 Chevrolet Silverado Z71, and discover that the Duramax Diesel is the ONLY engine to get!

There are 3 engine choices, the standard, 5.3-liter V8 with 355 horsepower and 383 pound-feet of torque is definitely underpowered, and the 420-hp, 6.2-liter V8 which, is only offered in some models, and will spend a lot of time at the pump.

The Goldilocks choice is the excellent 3.0-liter DOHC I-6 Turbo-Diesel, which although down on power to the V8s with 277 hp, offers up a stonking 460 lb-ft @ 1500 rpm. Add to that excellent fuel economy of 20 city, 26 highway, and 22 combined. During the loan, my heavy right foot was able to average 20.1 mpg. Get it on a long run on the highway and the turbo-diesel is good for a possible 728 miles between fill-ups.

It will also tow up to 9,300 lbs in the 4WD model and 9,500 lbs in the 2-wheel drive model.
