A bombshell report final week claims that Basic Motors will quickly supply a dealer-installed supercharger bundle for its line of T1 platform full-size SUVs. Per Motor Development, a $10,000 package will add as much as 200 horsepower on 6.2L V8 powered Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, and/or Cadillac Escalade SUVs. The package would additionally embrace brake and suspension upgrades.

Nevertheless, the report is essentially unfaithful.

Right here’s what’s actually taking place: the Cadillac Escalade is getting a supercharged V8. From the manufacturing facility. MC&T first reported this again in 2019, and in the event you’ve been maintaining with us, you already knew this.

Since our unique report, rumors have percolated that Basic Motors is supercharging its pickup vehicles to compete with the Ram TRX and Ford F-150 Raptor, which we needed to make clear hasn’t been permitted for manufacturing. A product providing that’s been explored. Not permitted.

The identical goes with allegations of GM fixing to supercharge its Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon and Cadillac Escalade SUVs by way of a dealer-installed supercharger package. It’s been an explored risk, however stays on maintain, at greatest. In response to our community of sources, there’s a stronger risk that the proposal went stillborn. Very like the sixth-generation Chevrolet Camaro Z/28.

In different phrases, it isn’t “taking place,” because the report suggests. As a result of as Basic Motors plunges deep into a totally electrical automobile portfolio, a dealer-installed supercharger improve for V8 SUVs appears to go towards present marching orders, one would possibly say.

The unique report additionally cross-wires the rationale as to why GM’s T1 platform SUVs characteristic encrypted ECUs stemming from GM’s new International B electrical structure, AKA the GM Car Clever Platform (VIP), and why GM’s T1 pickup vehicles don’t at the moment have the identical ranges of cybersecurity. It’s to not nook the aftermarket, because the report claims. That’s merely a consequence.

The solely motive is that the neural programs of the T1 Chevrolet Silverado and GMC Sierra vehicles merely don’t but function on GM VIP. They nonetheless run on a earlier technology {hardware}, which doesn’t but help the processing energy, OTA updates, greater decision screens, or encrypted management models.

Nevertheless, this modifications with a coming 2022 mannequin 12 months refresh for the Chevrolet Silverado and GMC Sierra. Once more, you learn it right here first some time in the past.

The MT report can be incorrect concerning the engine below the hood of GM’s SUVs. The 6.2L V8 is the L87, not the LT1. Sure, there are engineering variations. The one GM automobile providing an LT1 in the mean time is the Chevrolet Camaro, whereas the C8 Corvette completely makes use of the LT2.

All of this isn’t to say that Basic Motors shouldn’t supercharge its SUVs. Anyone with a very good learn on the heartbeat of the market is aware of that loads of deep-pocketed prospects would gladly pay up for extra energy in these full-sized behemoths. We’d wager the corporate is leaving piles of cash on the desk in the event that they don’t. However since we’re within the enterprise of reporting information, we thought you’d prefer to know that you just shouldn’t be planning on it taking place.
