GM’s Full-Size Chevy Tahoe, GMC Yukon, And Cadillac Escalade To Be Supercharged

GM was missing out on the hot super-powerful luxury SUV party. They’re about to fix that


  • The demand for high-powered large SUVs is enormous.

  • The supercharger could boost output to over 600 horsepower.


There’s no doubt that GM’s family of fully overhauled full-sized SUVs is good, very good in fact. Everyone and anyone who comes into contact with one praises it for its smoothness, refinement, technology, and design. And while the offered V8 engines are more than adequate, there are many buyers that would like more power. With a supercharger slapped onto the 6.2-litre V8, their wishes are about to come true.

The collection super-SUVs might be limited to nameplates such as the BMW Alpina X7, the Audi RS Q8, the Mercedes-AMG GLS 63, and, why not, the Dodge Durango SRT Hellcat and the Lamborghini Urus, but there’s room for more. According to Motor Trend, GM will offer a supercharger for its large SUVs however it’s looking like it will not be a factory-installed option. Don’t expect a “Blackwing” badge on the Cadillac Escalade

It appears as though dealerships will be tasked with installing the blower to the LT1 6.2-litre V8 that already produces 420 horsepower. The final output is unknown however should hover between 600 and 625 horsepower.

Interestingly, the source story ads that Hennessey has been unable to tune the SUVs’ ECU although they’ve been able to hack the pickups’ brain. In a way, this seems to point to the fact the GM wants to tweak its SUVs itself.

Pricing is not yet known but the installation will likely be warrantied by the maker.
