GM, the new Rally Sport Truck package will drop the 6.2-liter V-8 found in the GMC Yukon Denali into the Tahoe’s engine compartment.
With the additional 65 horsepower, the Tahoe will launch to 60 mph in less than 6 seconds.
Still, such a speedy zero to sixty time wouldn’t necessarily come from an additional 75 horsepower.
However, if owners opt to further the vehicle’s performance, they can squeeze out an additional 10 horsepower by ordering an optional Borla exhaust system.
Currently found in the Camaro ZL1, this high performance transmission allows for improved acceleration thanks to shorter gearing and will be a standard pairing with the 6.2-liter V-8 option.

2018 Chevrolet Tahoe RST Special Edition Amps Up Attitude, Horsepower
Chevy also announced that the 2018 Chevrolet Suburban SUV will be offered in an RST edition.
Chevrolet on Wednesday revealed the 2018 Chevrolet Tahoe RST (Rally Sport Truck) special edition, with a number of model-specific appearance upgrades and the option of the most powerful engine ever offered in the brand’s full-size SUV.
Also included in the performance package is Magnetic Ride Control, another first for the Tahoe.
The extra grunt arrives courtesy of a new performance package that includes a 6.2-liter V8 that delivers an estimated 420 horsepower and 460 pound-feet of torque.
A Chevrolet spokesperson told Edmunds that the 2018 Tahoe and Suburban will begin arriving at dealerships this fall, the Performance Package will be available this coming winter, and pricing will be announced closer to the on-sale date.
As it stated in To get it, one must first purchase the RST, which opens the gate for the Performance package, technically making it the Tahoe RST Performance package.
It looks nice, but here’s where things get interesting: An optional Performance package will be offered, but for the Tahoe only.
Although GM isn’t done putting the truck through its paces, at this point it’s comfortable quoting a 5.7-second zero-to-60-mph time; the tow rating for the Tahoe RST with the Performance package is 8400 pounds.
But Suburban buyers can’t get the Performance package (6.2-liter V-8, 10-speed automatic, Magnetic Ride Control dampers bundled together) from the factory as a package, no matter how much cash they wave around.
The ongoing industry-wide effort to imbue bulky full-size SUVs with styling cues and driving dynamics that intrinsically belie their hefty, oversize stature gains momentum with Chevrolet’s announcement of RST packages for the Tahoe and the Suburban.
