The all-new, next-gen 2021 Chevy Tahoe and 2021 Chevy Suburban offer a long list of upgrades and updates over the preceding generation, including the option for a new diesel powerplant. Now, the 2021 Chevy Tahoe diesel and 2021 Chevy Suburban diesel are available to order.
Order books for the new 2021 Chevy Tahoe diesel and 2021 Chevy Suburban diesel opened October 29th. Production of the diesel-powered SUVs started on a limited basis in November, although the diesel engine option will be very much constrained during the first four weeks of production.
The launch schedule for both next-generation SUV nameplates is now in its third and final phase, with all packages, trim levels, and the new turbodiesel engine option available to order. Check out our previous coverage of the 2021 Chevy Tahoe launch schedule for more information.
To note, the diesel engine in question is the 3.0L I6 LM2 turbodiesel Duramax, which produces 277 horsepower at 3,750 rpm and 460 pound-feet of torque at 1,500 rpm. The LM2 diesel engine is offered on every Tahoe and Suburban trim level with the exception of the off-roader Z71.
Both the 2021 Chevy Tahoe and the 2021 Chevy Suburban are also offered with the naturally aspirated 5.3L V8 L84 gas engine, which produces 355 horsepower and 383 pound-feet of torque, as well as the naturally aspirated 6.2L V8 L87, which produces 420 horsepower and 460 pound-feet of torque.
All three engines mate to the GM Hydra-Matic 10L80 10-speed automatic transmission.
