Alas, the duo of full-size SUVs makes due with the standard (and only) 5.3L V8 L83, which makes 355 horsepower and 383 pound-feet of torque compared to the larger and more powerful 6.2 L86, which makes 420 horses and 460 pound-feet of torque. In fact, L86 is essentially the same engine as the 6.2L V8 LT1 from the C7 Corvette Stingray, albeit with a different tune.
|Engine:||5.3L V8 L83||6.2L V8 L86||6.2L V8 LT1 (Corvette)|
Interestingly, the Tahoe and Suburban are the only GM vehicles based on the K2XX platform in which the 6.2L V8 L86 is not available. And that brings us to our question: should the motor be offered in the Tahoe and Suburban, at the least as an option? Vote in the poll below, and then share your thoughts in the comments section.
