Between things like Rally, Redline, and Midnight Editions, there are no shortage of appearance packages for various Chevrolet models. But this RST kit for the 2018 Tahoe and Suburban isn’t just a trim-and-tape job. Sure, the required big wheels and blacked-out elements are accounted for, but the RST job has a few more interesting tricks up its sleeve, too.
Chevy will offer the Tahoe RST with an optional performance package, the highlight of which is General Motors’ 6.2-liter V8, good for 420 horsepower and 460 pound-feet of torque. It’s mated to the company’s 10L80 10-speed automatic transmission, and that combination is apparently good enough to rocket the three-row, body-on-frame Tahoe from 0 to 60 miles per hour in 5.7 seconds. The performance pack also adds GM’s lovely Magnetic Ride Control suspension, meaning this Tahoe ought to have some pretty great road manners. Did we mention it can tow 8,400 pounds?
Performance pack not enough? Chevy will also sell you red-painted, six-piston, fixed aluminum Brembo brake calipers (clamping down on 16-inch rotors), as well as a Borla exhaust out back. (Executives tell us the Borla setup is good for an additional 10 hp at the rear wheels.) Want the brakes and the pipes but don’t care about the extra power? Well, you’re silly, but Chevy says it’ll offer the Borla/Brembo kit as standalone options.
Sad news for Suburban shoppers, though – Chevy isn’t offering its biggest boy with the performance package. Sure, you can still get the brakes and exhaust, but that’s as far as your performance upgrades will go. Regardless of vehicle, the 22-inch wheels, body-colored grille surround, black bowtie, and more, all come standard.
Look for the RST models to launch sometime in late 2017, with pricing information available closer to the on-sale date. Chevy’s press release below has even more details.

RST Special Edition Brings Street Look and Power to the New Chevrolet Tahoe and Suburban
Tahoe RST available with 6.2L V-8, 10-speed automatic transmission and Magnetic Ride Control
DETROIT — Today, Chevy introduced a new special edition for the Tahoe and Suburban: the street-performance Rally Sport Truck, or RST. The Tahoe RST will also be available with a new Performance Package that includes a 420-hp, 6.2L V-8 engine; Magnetic Ride Control with performance calibration; and an all-new Hydra-Matic 10L80 10-speed automatic transmission.
“Chevrolet has continually invested in Tahoe and Suburban, developing models with varying combinations of capability, technology and performance to meet the needs of different customers,” said Sandor Piszar, Chevrolet Truck Marketing director. “The RST is designed for customers who want a street performance look without sacrificing capability or refinement, along with the option of increased performance as well.”
RST will be available on Tahoe and Suburban models in the fall of 2017. Inspired by aftermarket trends, virtually all chrome trim has been eliminated for a street performance appearance. Changes include body-color grille surround and door handles; gloss-black grille and mirror caps; black roof rails, window trim, badging and Chevy bowties. RST also includes exclusive 22-inch wheels wrapped in Bridgestone P285/45R 22 tires.
Available upgrades for Tahoe and Suburban RST include a Borla performance exhaust system that offers a 28 percent improvement in exhaust flow, for a 7-10-horsepower gain at the rear wheels. An available brake package features massive front red Brembo six-piston, fixed aluminum calipers with brake pads clamping on larger-than-stock 410 x 32mm (16.1 inch x 1.3 inch) Duralife rotors coupled with a 84 percent increase in brake pad area and a 42 percent increase in rotor area to increase system thermal capacity. Duralife™ rotors feature a hardened surface to reduce corrosion and provide quieter braking with less vibration.
The Tahoe RST will also be offered with an exclusive Performance Package that includes Magnetic Ride Control with performance calibration, 6.2L V-8 and the new 10L80 10-speed automatic transmission.
This is the first time Tahoe will offer the 6.2L V-8, which delivers an estimated 420 horsepower and 460 lb-ft of torque. The engine features three state-of-the-art technologies — direct injection, Active Fuel Management and continuously variable valve timing — to make the most of power, torque and efficiency across a broad range of operating conditions.
The 6.2L V-8 will be paired with an all-new 10-speed automatic transmission. With smaller steps between each ratio, the transmission maximizes engine power under acceleration. With a wide 7.39 overall gear ratio spread and lower numerical top gear ratio, the transmission also improves efficiency by reducing engine revolutions at highway speeds.
Based on preliminary estimates, the Tahoe RST Performance Package will offer a towing capacity of 8,400 pounds and the truck will be cable of 0-60 mph acceleration in less than 6 seconds. Full performance metrics will be announced closer to launch.
Magnetic Ride Control is an active suspension that “reads” the road every millisecond, triggering damping changes in the electronically controlled shock absorbers in as few as 5 milliseconds. As a result, the suspension delivers both improved body-motion control during cornering and a more comfortable ride while cruising. The new performance calibration included in the Tahoe RST Performance Package increases body control for even higher levels of responsiveness and comfort.
“When you want to hustle, it is incredibly fast, with significantly higher levels of acceleration, braking and road-holding grip,” said Eric Stanczak, chief engineer for Chevrolet full-size trucks. “When you want to relax, it is very refined, with exceptional ride comfort and interior quietness.”
Chevrolet has been the best-selling full-size SUV brand for 42 years. Today, Tahoe and Suburban are the top two vehicles in the segment. They also account for 49.3 percent of retail sales, or nearly one out of every two full-size SUVs Americans bought in 2016. Tahoe and Suburban customers are also the most loyal owners in the segment, with 79 percent of owners replacing their vehicle with another Tahoe or Suburban.
