This Program Has Been On The Drawing Board, However

A T1 Chevrolet Silverado with a supercharged V8 engine would be nice, wouldn’t it? And that’s the subject for the big story of the day, as TFL received recent intel that General Motors is working on fitting a supercharged V8 engine into either a new pickup truck or SUV based on the T1 platform. This is a broad detail, although it validates what we’ve reported on nearly a full year ago today. The outlet has been keen on breaking several future product details lately, and of course, they’re technically correct in this case. However, we’d like to add to the report with intel that only MC&T can provide at this time.

For those wondering, we understand that the “supercharged V8” is none other than the LT4, a 6.2L supercharged small block V8 engine that can only be found in one vehicle in production right now: the Chevrolet Camaro ZL1. It was otherwise found in the C7 Corvette Z06 and third-generation Cadillac CTS-V. Depending on the application, it produced between 640-650 horsepower. Indeed, it would be a great addition to GM’s full-size truck and SUV family. We’d love to see a Chevrolet Tahoe SS, or a new Chevrolet Silverado SS.

Unfortunately, future use of the LT4 will be severely limited.

If you’ve been watching this space, we’ve already reported on the T1 program involving a supercharged V8 engine that GM is working on: the Cadillac Escalade. Whether it’s called the Escalade-V or the Escalade-V Blackwing remains a fluid situation, but it’s nevertheless on the way. At this time, we understand that there are no plans to fit the LT4 into the Chevrolet Tahoe, Chevrolet Suburban, or GMC Yukon.

Being the first outlet to exclusively report on the LT4’s involvement in the GM T1 truck and SUV program, we also need to elaborate that absolutely nothing has changed with this plan. The Escalade is the only vehicle that’s been approved to receive the LT4 at the time of this writing.

In fact, the only recent updates to the T1 portfolio is that short-term product debuts have been delayed a few months due to the COVID-19 pandemic. This included the 2022 model year refresh to the Chevrolet Silverado and GMC Sierra, which are expected to adopt interior designs found in the new Chevrolet Tahoe and GMC Yukon.

That said, we understand that there is otherwise indeed a supercharged Chevrolet Silverado program pending review with LT4 power. But the program has neither been approved, nor canceled. And this has been the case for at least a year now. Unfortunately, the longer GM mulls it over, the less likely it will become a reality.

GM has otherwise approved an off-road variant of the Chevrolet Silverado, and was teased during the 2019 SEMA Show as the Hall Racing Chevrolet Silverado race truck. It features Multimatic DSSV dampers and other off-road suspension hardware found in the smaller Chevrolet Colorado ZR2. We will have more details on this truck program shortly.

Considering the massive hole that the COVID-19 pandemic will leave on GM’s balance sheet, it’s hard to think that the automaker will have much of an appetite for increasing any spending involved in developing an LT4 for use in its trucks. Couple that with current “all electric future” marching orders, and it’s easy to speculate that GM would rather spend its money on a Silverado EV, rather than a supercharged Silverado SS.

Be sure to stay tuned to MC&T as this product timeline continues to develop, as well as for the latest GM pickup truck and SUV news.

Muscle Cars & Trucks was founded by Manoli Katakis - an automotive media veteran that has been covering the latest car news since 2009. His journalism has uncovered dozens of major product changes, updates, plans, and cancellations long before automakers were ready to make things official.

Some highlights over the years of his reporting include the uncovering of the Zora trademark before anybody else reported on the coming of a mid-engine Corvette, as well as the dead-accurate reporting of the coming of the Chevrolet Colorado ZR2, two years before it hit the market, and even before the debut of the concept vehicle. This type of reporting has immediately continued here, with reports of the original seventh-generation Camaro plans being shelved, as well as what's in store for the Chevrolet Silverado.

Some of his work can be found on massive automotive media outlets, such as Motor1. He also has been a guest on the 910AM Radio Station with Detroit News auto critic Henry Payne, as well as the enthusiast-oriented Camaro Show podcast.

Over the years, Manoli has interviewed various automotive industry titans, leaders, and people that make things happen otherwise. These include figureheads such as GM CEO Mary Barra, GM President Mark Reuss, automotive aftermarket icon Ken Lingenfelter, Dodge firebrand Tim Kuniskis, along with various chief engineers of vehicles such as the Ford F-150 & Mustang, Chevrolet Camaro & Corvette, and many more.

At MC&T, Manoli is taking his journalism expertise, deeply planted sources, driving abilities, and automotive industry knowledge to new levels, covering more vehicles and brands than ever before. This is the place where you will continue to read groundbreaking stories about American performance vehicles, pickup trucks, and sport utility vehicles. Here is where you’ll also read insights and quotes from various automotive subject matter experts on the latest relevant products, as well as some of the latest official news from their manufacturers.

Fun facts: he also once beat Corvette Racing driver Tommy Milner in an autocross with a Chevrolet Bolt EV. The biggest vehicle he’s ever driven is a John Deere mining truck. Besides a go-kart, the smallest vehicle he’s driven has been a Hyundai i10. He’s also spent time in the cockpit of various American performance vehicle icons, including the fifth-generation Chevrolet Camaro Z/28, Dodge Challenger Demon, and Ford Mustang GT350R. He has reviewed dozens of trucks, SUVs, and performance vehicles over the years.

One of his favorite new vehicles on the market today happens to be the Chevrolet Colorado ZR2 Bison. He is also a card carrying member of the Sports Car Club of America, and regularly participates in Detroit Region autocross events.
