The standard engine remains the 5.3-liter V-8 that generates 355 hp and 383 lb-ft of torque. But Tahoe RST buyers can opt for a performance package that for the first time gives the Tahoe the 6.2-liter V-8, which brings horsepower to 420 with 460 lb-ft of torque. The direct-injection engine has active fuel management and continuously variable valve timing.

The performance package includes Magnetic Ride Control suspension calibrated for a performance vehicle to respond to the road and maintain control even while being tossed around more.

Available upgrades include a Borla performance exhaust system that offers a 28 percent improvement in exhaust flow, for a 7- to 10-horsepower gain at the rear wheels. Opt for the brake package to get red Brembo six-piston, fixed-aluminum calipers and larger Duralife rotors. These options are available on standard Tahoes and Suburbans, as well.
