Massive SUV joins sub-six seconds club
CHEVROLET HAS INTRODUCED A SPECIAL EDITION MODEL TO ITS Tahoe and Suburban full-sized – read very large – SUV ranges, the incongruously-named Rally Sport Truck, or RST.
Chevy says the RSTS – on sale from the northern hemisphere autumn – have been stripped of virtually all chrome trim to achieve “a street performance appearance.”
The Tahoes and Suburbans get body-colour grille surrounds and door handles; gloss-black grille and mirror caps; and black roof rails, window trim and Chevy bowtie badges. They also have 22-inch alloy wheels and Bridgestone P285/45R 22 tyres.
Options include a Borla performance exhaust system which Chevy says improves exhaust flow by 28 percent, gaining 5kw to 7.5kw at the rear wheels.
Also available is a brake package with massive front red Brembo sixpiston aluminium calipers with brake pads clamping on larger-than-stock 410mm by 32mm Duralife disc rotors.
The brake package has 84 percent more pad area and a 42 percent increase in rotor area for increased thermal capacity.
The Tahoe RST’S performance Package includes performance-calibrated Magnetic Ride Control, a 6.2-litre V8, and the new 10L80 10-speed automatic transmission.
The 6.2-litre V8, which delivers an estimated 313kw and 624Nm is a first for the Tahoe, and has direct injection, Active Fuel Management and continuously variable valve timing.
The all-new 10-speed automatic has smaller steps between each ratio to maximise engine power under acceleration.
Chevy says preliminary estimates give the Tahoe RST Performance Package a braked trailer towing capacity of 3800kg and acceleration to 96km/h in less than six seconds.
“When you want to hustle, (the RST) is incredibly fast, with significantly higher levels of acceleration, braking and road-holding grip,” says Chevrolet full-size trucks chief engineer, Eric Stanczak. “When you want to relax, it is very refined, with exceptional ride comfort and interior quietness.”
Chevy’s truck marketing director, Sandor Piszar, says the RSTS are designed for customers who want “a street performance look without sacrificing capability or refinement, along with the option of increased performance...”
