General Motors is currently considering an expansion to the availability of the naturally aspirated 6.2L V8 L87 engine in the automaker’s all-new full-size SUV lineup, GM Authority has learned. According to GM Authority sources, GM may offer the 6.2L V8 L87 on additional trims for the new Chevy Tahoe, Chevy Suburban, and GMC Yukon/Yukon XL.
Currently, the 6.2L V8 L87 is only offered on a single trim level for the new Chevy Tahoe, Chevy Suburban, and GMC Yukon/Yukon XL. More specifically, the engine is equipped as standard on the 2021 Chevrolet Tahoe High Country, 2021 Chevrolet Suburban High Country, and 2021 GMC Yukon Denali/Yukon XL Denali. Critically, the 6.2L V8 L87 is not offered on any other trim level in each of three nameplates mentioned, not even as an option.
The rest of the trim levels for these three full-size SUVs come with the naturally aspirated 5.3L V8 L84, while the 3.0L I6 LM2 turbodiesel Duramax is also offered on most of the trims. The 6.2L V8 L87 is the most powerful engine of three, producing 420 horsepower and 460 pound-feet of torque, as compared to the 355 horsepower and 383 pound-feet of torque produced by the 5.3L V8 L84, and the 277 horsepower and 460 pound-feet of torque produced by the 3.0L I6 LM2 turbodiesel.
|Engine||Power (hp @ RPM)||Torque (lb-ft @ RPM)|
|6.2L V8 L87||420 @ 5600||460 @ 4100|
|5.3L V8 L84||355 @ 5600||383 @ 4100|
|3.0L I6 LM2||277 @ 3750||460 @ 1500|
It’s currently unclear when the expanded availability of the 6.2L V8 L87 gas engine will go into effect, or which trim levels in the new Chevy Tahoe, Chevy Suburban, and GMC Yukon lineups will get the revised engines structure.
As a reminder, all three full-size SUVs were overhauled for the 2021 model year, riding on the all-new GM T1 platform and offering revised styling, a new interior design, and the latest technology.
