Chevrolet recently announced the new Suburban RST Performance Package. Featuring a 420-hp, 6.2L V-8 engine, Magnetic Ride Control with performance calibration and a new Hydra-Matic 10L80 10-speed automatic transmission, the Suburban RST Performance Package brings a seamless blend of style and performance to Chevy’s portfolio of full-size SUVs.
“The RST Performance Package made its debut on the Tahoe RST last spring, and the response from our customers was overwhelmingly positive,” said Sandor Piszar, director of Chevy Trucks Marketing and Advertising. “In fact, Tahoe RST with the Performance Package is the fastest-turning Tahoe model, and we’ve received customer requests to offer the same performance and power to Suburban RST. Delivering on those requests with the Suburban RST Performance Package is another example of how Chevrolet has continually invested in the segment, developing models with combinations of capability, technology and performance to meet the needs of different customers.”
Available later this summer, this is the first time Suburban will offer the 6.2L V-8, which boasts 420 horsepower and 460 lb-ft of torque. The engine delivers three state-ofthe 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. Suburban RST will also feature a new 10-speed automatic transmission. Smaller steps between each ratio maximize engine power under acceleration. With a wide 7.39 overall gear ratio spread and lower numerical top gear ratio, the transmission also reduces engine revolutions at highway speeds.
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 Suburban RST Performance Package increases body control for even higher levels of responsiveness and comfort.
“When you want to hustle, the Suburban RST with the Performance Package offers high 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.” Available performance accessories for Suburban RST include a custom tuned Performance Dual-Side Exit exhaust system designed, engineered and backed by Borla, with sleek exhaust tips that improve exhaust flow by 28 percent for enhanced performance and decreased fuel consumption. An available Performance front brake upgrade package designed, engineered and backed by GM features massive red Brembo six-piston, fixed aluminum calipers with brake pads clamping on largerthan stock 410 x 32mm Duralife rotors coupled with an 84 percent increase in brake pad area and a 42 percent increase in rotor area to increase system thermal capacity.
The Performance Package is available as an upgrade to the Suburban RST, which was introduced last year. Styling is based largely on trends in the aftermarket space — virtually all chrome trim has been eliminated for a sporty, street appearance. Changes include body-color grille surround and door handles; gloss-black grille and mirror caps; and black roof rails, window trim, badging and Chevy bowties. RST package also includes 22-inch wheels wrapped in Bridgestone P285/45R 22 tires.
