Back in May, we broke the news that the all-new 2021 Chevy Tahoe diesel and equally all-new 2021 Chevy Suburban diesel would have late availability. Now, GM Authority has exclusively learned that both oil-burner next-gen SUVs will be available to order in November.
In both models, the engine in question is the 3.0L I6 LM2 turbodiesel Duramax, which features dual-overhead cams and direct injection. The LM2 diesel engine is offered as an available option for every trim level with the exception of the off-road Z71. When equipped in the 2021 Chevy Tahoe diesel and 2021 Chevy Suburban diesel, the LM2 engine produces 277 horsepower at 3,750 rpm, and 460 pound-feet of torque at 1,500 rpm.
The rest of the engine lineup includes the naturally aspirated 5.3L V8 L84, which produces 355 horsepower and 383 pound-feet of torque, and the naturally aspirated 6.2L V8 L87, which produces 420 horsepower and 460 pound-feet of torque. All three engines connect to the GM Hydra-Matic 10L80 10-speed automatic transmission.
The 2021 Chevrolet Tahoe and 2021 Chevrolet Suburban debuted side-by-side late last year in a special event in downtown Detroit. The 2021 Chevy Tahoe diesel and 2021 Chevy Suburban diesel join the lineup for the first time with this next-gen overhaul, which also includes a new underlying architecture, namely GM’s T1 platform, as well as a new independent multilink rear suspension. Further updates include revised exterior and interior designs, and the latest technology features.
Both models are assembled by GM USA at the GM Arlington plant in Arlington, Texas. Production for the 2021 Chevrolet Tahoe kicked off June 26th, 2020, while production of the 2021 Chevrolet Suburban kicked off July 13th.
