It’s looking as though General Motors could be cooking up a go-fast variant of the new Chevrolet Tahoe. Believed to be called the Chevrolet Tahoe SS, the future performance SUV is tipped to equip the supercharged 6.2L V8 LT4.
According to a recent report from TFL Truck, which cites an anonymous tipster with “inside knowledge of GM powertrain development,” The General is currently working on a high-performance truck version of one of its 6.2L V8 engines. Although the report does not specify power levels, which 6.2L engine will be used, when we’ll see it, or exactly which model will receive the powerplant, it does say that it may power a future Chevrolet Tahoe SS model, and/or the upcoming Chevrolet Silverado 1500 ZRX performance off-roader.
GM Authority was the first to report on the upcoming Chevrolet Silverado ZRX back in August of 2019 after GM made a trademark filing for the “Silverado ZRX” name. We previously speculated that the ZRX would come equipped with the naturally aspirated 6.2L V8 L87, and instead focus on suspension and body upgrades, offering a similar approach as the Chevrolet Colorado ZR2. From what we know, this is still the case, but it now appears that more power may also be optional.
What’s more, we know that GM will offer a high-performance version of the next-generation Cadillac Escalade, as we reported back in July of 2019. It’s certainly possible that the go-fast Escalade will come equipped with the supercharged 6.2L V8 LT4 for motivation.
For reference, the supercharged 6.2L V8 LT4 was previously offered in the now-discontinued Cadillac CTS-V, where it produced 640 horsepower and 630 pound-feet of torque. The LT4 was also equipped in the C7 Corvette Z06 and sixth-gen Camaro ZL1, making 650 horsepower and 650 pound-feet of torque.
Take all that blown V8 goodness and throw it under the hood of a new Chevrolet Tahoe SS model, and it could make for quite a potent combo.
