We reached out to General Motors asking them about MT’s report on a dealer installed supercharger option for the automaker’s trio of large SUVs, with a Cadillac spokesperson shooting down the rumor as “complete speculation” without saying anything further. [Updated 2/14/2021]

Rumors about a high-performance Cadillac Escalade-V were circulating a few years ago, but that now seems unlikely as officials recently suggested the CT4-V and CT5-V Blackwings would be the last petrol-powered V-Series models.

While that’s disappointing, it appears fans of high-performance SUVs won’t be entirely out of luck.

According to Motor Trend citing an inside source, GM will offer a supercharger for the Cadillac Escalade, Chevrolet Tahoe / Suburban and GMC Yukon. Little is known about the company’s plan at this point, but it appears the supercharger will be a dealer-installed option for models equipped with the 6.2-liter V8 engine.

In naturally aspirated form, the engine produces 420 hp (313 kW / 426 PS) and 460 lb-ft (623 Nm) of torque. It moves the SUVs with authority, but we wouldn’t exactly call them quick.

However, the supercharger could change that as the publication estimates they could increase the output to 600-625 hp (447-466 kW / 608-634 PS). That would be a significant jump and not too far off from the CT5-V Blackwing’s rating of 668 hp (498 kW / 677 PS).

There’s no word on when the supercharger could arrive or how much it will cost, but the publication noted the SUVs have a locked ECU.  This prevents tuners such as Hennessey Performance from offering their own high-performance versions and it means GM could see a boost from customers looking for more power.
