Among the significant highlights of the revamped full-size GM SUVs, the 2021 Chevrolet Tahoe as well as Suburban as well as the 2021 GMC Yukon as well as Yukon XL, is the newly found accessibility of a turbo-diesel engine, a 3.0-liter Duramax inline-six (obtained from the Silverado/Sierra pick-ups). Currently we have the gas economic climate approximates for the brand-new diesel as determined by the EPA, and also as anticipated they stand for a substantial enhancement over the next-most-efficient engine, the 5.3-liter V8.
The 2021 Chevrolet Tahoe 2WD is 21/28 mpg city/highway as well as 24 mpg integrated. The 4WD Chevrolet Tahoe diesel is 20/26 mpg as well as 22 mpg integrated. That’s a huge gain over the Tahoe with the 5.3-liter V8, which brings EPA price quotes of 16/20 mpg city/highway as well as 18 mpg integrated (2WD or 4WD).
The bigger Rural with 2WD as well as the diesel motor webs EPA price quotes of 21/27 mpg city/highway as well as 23 mpg integrated. Contrast that to 16/20 mpg as well as 18 mpg integrated for the Rural with the 5.3-liter V8.
With 4WD, the 2021 Rural diesel’s numbers are 20/26 mpg city/highway as well as 22 mpg integrated. Once again, that’s dramatically much better than the 4WD Rural 5.3-liter V8, which obtains 15/19 mpg as well as 17 mpg integrated.
Over at GMC, the Yukon 2WD’s freeway as well as consolidated price quotes are 1 mpg much less than those of its Chevy brother or sister, at 21/27 city/highway as well as 23 mpg in general. The Yukon XL 2WD has the exact same EPA numbers as the smaller sized Yukon. EPA numbers for the 4WD GMCs, both Yukon as well as Yukon XL, are 20/26 mpg city/highway as well as 22 mpg integrated.
Taking A Look At the GM SUVs’ closest competitor, the Ford Exploration (powered by a 3.5-liter turbo V6) is ranked at 17/23 mpg (RWD) as well as 17/22 mpg (4WD). The bigger Exploration Max is 17/22 mpg (RWD) as well as 16/21 mpg (4WD).
GM’s Duramax diesel cranks out 277 horse power as well as 460 lb-ft of torque, as well as brings optimal lugging scores of 8,000 extra pounds with the Rural as well as 8,200 extra pounds with the Tahoe (RWD). It’s a $995 alternative over the 5.3-liter V8 on the majority of trim degrees, however in the High Nation, which comes criterion with the 6.2-liter V8, choosing the diesel webs customers a $1,500 credit history.
