For the 2023 model year here at the Mid-Missouri Powerhouse, the smaller Duramax received new fuel injectors and pistons, along with a completely reworked combustion bowl. Horsepower output jumped from 277 to 305 horsepower, while torque jumped from 460 to 495 lb-ft. This officially crowned the Duramax the reigning champion of internal combustion torque. Even when you’re enjoying the excitement of wide-open throttle, the diesel model is quieter than its 6.2-liter sibling. The Car and Driver crew got to test a ZR2 and a Trail Boss model and noted that the tires were even louder than the powertrain!
When they tested the first-generation engine in a 2020 Silverado LTZ, the truck hit 60 mph in just 7.1 seconds! The quarter mile is a very defining test of any vehicle, as it allows for a layman’s true glance at blistering accomplishment. The 2020 model negotiated firmly with the quarter mile laying down 15.5 seconds at 88 mph. The 2024 ZR2 carries around an extra 145 pounds and is nicely wrapped in Goodyear Wrangler Territory MT tires. The 60-mph time is just 6.8 seconds, and the quarter mile now rings in at 15.3.
The revised engine felt incredibly responsive to this team, and the highway fuel economy ebbed in a constant and eagerly delivering rpm. One of the quite necessary elements to recognize here is that the full-size pickup market can seem saturated. This provides any single truck a quite well-equipped black book to have to hurriedly contend with! The Motor Trend review team had taken their Silverado to conquer the steep incline at the Davis Dam, which is near the Arizona-Nevada border.
They reflected that with all the frustrating elements they threw at it, the diesel still controlled the trailer amazingly well. These hard-boiled experts even made it a point to roll their entire operation across a certified CAT scale, to double-check their weight to the T. Throughout 2,627 miles of towing they nailed down their “best tank” averaging to around 14.02 mpg under ideal weather conditions. The 2024 Silverado is fitted with a 5.5-gallon tank idea for storing DEF, with the ability to resiliently power through an oil-change cycle of 7,500 miles.
The Hagerty
review team got behind the wheel of this year’s ZR2 and
“immediately knew it was something special.” They loved writing home about the
suspension that eats up just about anything you can throw at it on the trail,
without compromising its easy-going highway manners. The performance proved to
be quite potent, as tipping into the throttle nets a very immediate and
satisfying torque response. While climbing steep grades on the highway, the
turbo was the perfect medium for the engine to easily rev toward its peak power
at 3750 rpm.
Pickups’
strength, versatility, and undeniable charm are exactly why buyers of all types
are after them. When the Gear Junkie blog tried out the Silverado
for a test drive, they were fond of the insanely large amount of room and
instantly commanding view of the road. These all-in truck addicts claimed that
the menus “are intuitive enough, the response time of the touchscreen is
acceptable, and the 13.4-inch screen is bright.
