2021 Chevrolet Suburban, Tahoe Get a Diesel Option

Chevrolet revealed the 2021 Suburban and Tahoe SUVs and with it came the announcement that each will be available with a diesel engine under the hood.

The optional Duramax 3.0L inline-six turbo-diesel is available on all models except Z71. It is rated at 277 hp and 460 lb-ft of torque.

The engine’s components include iron cylinder liners within the aluminum engine block, a forged steel crankshaft and connecting rods and blended silicon/aluminum pistons for greater heat resistance and reduced expansion.

A 5.3L V-8 rated at 355 hp is standard on LS, LT, Z71, RST and Premier models; and a 6.2L V-8 rated at 420 hp is standard on High Country. Both feature Dynamic Fuel Management technology, with more than 12 modes of cylinder deactivation that are designed to optimize engine efficiency across a broad range of driving conditions, including when towing a trailer. The engines also feature automatic stop/start technology, direct injection and variable valve timing, which all contribute to the balance of performance and efficiency.
