2018 Chevrolet Tahoe

Chevy introduces a new special edition for the 2018 Tahoe: the street-performance Rally Sport Truck, or RST. The Tahoe RST is 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 10-speed automatic transmission.

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 is offered with 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.

With smaller steps between each ratio, the all-new 10 speed 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 offers a towing capacity of 8,400 pounds and 0-60 mph acceleration in less than 6 seconds.
