US market sales will start in mid-2020 GM says

General Motors is hoping that offering its Flint, Michigan-built 3.0-litre I6 diesel in two new full-sized SUVs will give them an advantage over competitors.

Chevrolet's 2021 model year Tahoe and the long-wheelbase 2021 Suburban have independent rear suspension for the first time in the models' decades-long history and can be optionally equipped with air springs. 

The new models are the first SUVs for GM's VSS-T body-on-frame architecture. Dimensions have changed dramatically for the Tahoe, which gains 170mm over the current, 202-inch long model. The Suburban is also lengthier, although only by 33mm.

Buyers of both models have the choice of three engines, each of which is linked to GM's 10L80 ten-speed automatic gearbox:

  • 207kW (277 horsepower) and 623Nm (460 lb-ft) 3.0-litre Duramax-branded in-line six-cylinder diesel (GM code: LM2)
  • 265kW (355 horsepower) and 519Nm (383 lb-ft) 5.3-litre 16v OHV gasoline V8
  • 313kW (420 horsepower) and 623Nm (460 lb-ft) 6.2-litre 16v OHV gasoline V8

The 2021 Yukon and Yukon XL - GMC's equivalents of the Tahoe and Suburban - are yet to be announced. The same applies to the successors for the Cadillac Escalade and Escalade ESV. The Arlington plant in Texas which builds all these models will also be where their replacements are manufactured.
