Suburban adds RST Performance Package
Chevrolet has announced the new Suburban RST Performance Package featuring a 420 hp, 6.2-litre V8 engine, Magnetic Ride Control with performance calibration and a new Hydra-Matic 10L80 10-speed automatic transmission. Available later this summer, this is the first time Suburban will offer the 6.2-litre V8, which boasts 420 horsepower and 460 lb-ft of torque. The engine delivers 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 new transmission has 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 five 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. 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 per cent for enhanced performance and decreased fuel consumption. An available performance brake package designed, engineered and backed by Brembo features massive front red six-piston, fixed aluminum calipers with brake pads clamping on larger-than-stock 410 x 32 mm (16.1 inch x 1.3 inch) Duralife rotors coupled with an 84 per cent increase in brake pad area and a 42 per cent increase in rotor area to increase system thermal capacity. Duralife rotors feature a hardened surface to reduce corrosion. 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. The Suburban RST is expected to boast a towing capacity of 8,100 pounds. Full performance metrics will be announced closer to launch.
