Chevy this month 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.
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.
“When you want to hustle, it is incredibly fast, with significantly higher levels of acceleration, braking and roadholding 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.”
