2018 Chevrolet Tahoe performs better with RST performance package

Article by Christian A., on April 13, 2017

Chevrolet offers an extensive collection of appearance packages for various models. The likes of the Rally, Redline, and Midnight Editions possess a certain aura of individuality compatible to its respective owners. Customers can choose from any of these appearance packages to suite their tastes – from the reliable Rally Edition to the classy Custom Sport HD. For 2018, Chevrolet is adding another exciting deal for their valued customers.

Chevrolet Tahoe and Suburban are getting a Rally Sport Truck (RST) package for 2018, but there’s more to it than meets the eye. This RST package is not your usual “trim-and-tape” makeover even as it does feature the usual “required” big wheels and blacked-out elements. That’s because it has more to offer and even has interesting tricks up its sleeve.

Pricing and other details (i.e. fuel economy) haven’t been released yet but the RST models are expected to launch sometime this coming fall while the V8 upgrade will come shortly after (pricing information may be available close to its on-sale date, though).

RST Special Edition is expected to bring out the “street look” and power of the new Chevrolet Tahoe and Suburban – Chevrolet’s top two vehicles in the SUV class, accounting to almost 50 percent of retail sales.

Exterior Design

For the exterior modifications, the RST package offers a Borla performance exhaust and red-painted, six-piston, fixed aluminum Brembo brake calipers for both the Tahoe and Suburban SUVs.

The exhaust gives a “throatier” sound and is said to add a dash of power to these SUVs. The powerful calipers, on the other hand, now come with larger 16-inch rotors and pads, contributing to the noticeable improvement in stopping power.

It is also said that the Borla set-up provides an additional 10 horsepower to the rear wheels. These options are not exclusive to the RST package alone, so other Tahoe and Suburban models may avail these upgrades through the GM Performance catalog.

More so, the RST package will give the Tahoe and Suburban the standard features such as unique 22-inch wheels, body-colored grille surround and headlight trim, black-painted window surround, mirror caps, grille centers, black bowtie, and many more.

Powertrain

The SUVs run on a standard 5.3-liter V8 engine – take note that this is “standard”, which means that there must be something special in store (cue: drum roll). The Tahoe RST, for performance-oriented customers, is offered with an optional performance package. What does this mean? Well, it just means that it may now be availed with General Motor’s 6.2-liter V8 engine – the main star of the show.

It is capable of producing 420 horsepower and 460 pound-feet of torque. When mated to the 10L80 10-speed automatic transmission (the same transmission found in the Camaro ZL1 and Ford F-150 Raptor), it allows the three-row, body-on-frame Tahoe RST to accelerate (from 0 to 60 mph) in 5.7 seconds. This also allows the Tahoe RST a towing capacity of 8,400 pounds.

This configuration allows both the Brembo brakes and Borla exhaust, the latter adding 10 horsepower more at the wheels. GM’s Magnetic Ride Control suspension is also part of the performance package, which means that road trips with the Tahoe will be as smooth as baby’s skin.

Unfortunately, the additional V8 performance package is only available for the Tahoe RST and not for the Suburban; the latter is offered with only the appearance package and optional exhaust and brakes. However, both two-wheel and four-wheel-drive models may avail any of the packages offered.

Press Release

RST SPECIAL EDITION BRINGS STREET LOOK AND POWER TO THE NEW CHEVROLET TAHOE AND SUBURBAN

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.
