If you are an auto enthusiast, you know, recognize and possibly idolize GM’s LT4 V8 engine. Tall-Powered V8s have a duty in some of the most serious and capable performance cars to launch the General: Corvette Chevy C7 Z06, Camaro ZL1and Cadillac CT5-V Blackwing and Escalade-DRAW. While the LT4 was used in only a handful of those cars, it was almost certainly used in another, more unexpected vehicle. register.

LT4 is almost done Chevrolet’s Tahoe RST Performance Edition. That’s at least What sources are close to the said issue? GM agency. If you’re not familiar, Tahoe RST Performance Edition is a slightly hotter version of the Tahoe RST. And when I say a little, I mean it. Slight tweaking of the engine to a 6.2-liter V8 resulted in an extra 13 hp and 7 lb-ft torque for a total of 433 hp and 467 lb-ft of torque. Nothing to sneeze for sure. It’s enough to get this huge SUV to 60 mph in just 5.7 seconds, which is very impressive for something that weighs almost 6,000 pounds. And More power will be enthusiastic welcomeespecially if it’s in form of LT4. Therefore, why is it not used?

The GM Authority has elucidated in detail why, instead of engage in speculation instead. But, I decided to ask someone at Chevy myself.

Chevrolet has intentionally selected the 6.2L engine with performance tuning and touch system for the RST Performance Edition. This implementation gives customers a solid performance boost, while still being able to deliver performance instances at an affordable price.

So there it is. We aren’t getting a bargain Escalade-V. While it sucks that they didn’t do it, its understandable given the kind of money something like that would have commanded. At least they even considered it.
