Chevrolet will expand its Tahoe and Suburban full-size SUV ranges this fall with the Rally Sport Truck, or RST, trim, an appearance package it says was inspired by aftermarket trends.

The Tahoe RST starts out with cosmetic changes that include ditching almost all chrome trim in favour of a body-colour grille surround and door handles, and gloss black for the grille insert, mirror caps, roof rails, window trim and badging. All of that rides on a set of trim-specific 22-inch wheels.

But Chevy says the RST isn’t just about looks—at least, not if you’re willing to spend a bit more money. Optional is a 6.2-litre V8 borrowed from the GMC Yukon Denali, which comes paired with a 10-speed automatic transmission and GM’s slick Magnetic Ride Control suspension.

This will mark the first time Chevrolet will install in the Tahoe the pack-a-punch 6.2-litre engine, which delivers the same 420 hp and 460 lb-ft of torque as it does in the Denali and in GM’s full-size pickups. With that powertrain bolted in, Chevy says the big motor will march the Tahoe RST from zero to 96 km/h (60 mph) in less than six seconds and allow it to tow as much as 3,800 kg.

And in keeping with this truck’s aftermarket inspiration, other add-ons include a Borla exhaust system Chevrolet says adds up to 10 hp; and a brake package that swaps out the stock binders for six-piston Brembo calipers clamping upsized front rotors designed for reduced corrosion, noise, and vibration.

Pricing and final performance measurements will be announced closer to the RST package’s launch, later this year.
