Let’s get the important bits out of the way first: General Motors’ 5.3L L84 V8 gasoline engine will be standard on LS, LT, Z71, RST and Premier trim models, while the 6.2L L87 V8 will be standard on the High Country. The 5.3L engine is good for 355 horsepower and 383 pound-feet of torque, while the 6.2L engine makes 420 horsepower and 460 pound-feet of torque.
GM’s 3.0L LM2 I6 Duramax turbodiesel engine, which makes 277 horsepower and 460 pound-feet of torque, will be available on all trim levels except for the off-road-focused Z71. All models will also use the GM 10-speed automatic transmission with electronic shift, ditching the column shifter for a row of buttons in the process.
The 2021 Chevrolet Tahoe uses GM’s T1 platform and has a new independent multilink rear suspension, which GM says is the most sophisticated suspension in its class. The SUV offers GM’s existing Magnetic Ride Control system, but the vehicle is also offered with a new Air Ride Adaptive Suspension, available on the new range-topping High Country model and the Z71 off-road model. The Air Ride Adaptive Suspension has automatic load leveling and ride height adjustment, with up to four inches of adjustment available.
Also setting the new High Country model apart is a chrome dual exhaust, 22-inch wheels and chrome exterior trim. Meanwhile, the Z71 model gets standard four-wheel drive, a unique front fascia with red tow hooks, 20-inch wheels wrapped in all-terrain tires and Z71 exterior badging. The RST trim has returned as well, offering buyers LT content with a sport-inspired exterior appearance and 22-inch wheels.
A total of five different display screens will be offered in the SUV, depending on the trim level chosen. These include a standard 10-inch color touchscreen, an 8-inch digital instrument cluster, a segment-exclusive 15-inch head-up display and two 12.6-inch LCD rear-seat displays. The 10-inch screen comes standard with Apple CarPlay and Android Auto, a good compliment to the OnStar 4G LTE Wi-Fi hotspot. Multiple USB charging ports are also scattered throughout the cabin, while a wireless charging pad is standard on all models except for the entry-level LS.
The 2021 Chevrolet Tahoe looks to meet the towing expectations of full-size SUV buyers with a Max Trailering package, which includes a high-capacity radiator and cooling fan, an integrated trailer brake controller, Hitch Guidance with Hitch View and Chevrolet trailering app compatibility. The SUV also features up to exterior camera views to help make the towing experience less stressful, along with an in-vehicle trailering app with trailer profiles, trailer tire pressure and temperature monitoring.
As far as active safety goes, Automatic Emergency Braking will be standard on all models. Some of the available safety equipment will include HD Surround Vision, Rear Pedestrian Alert, Lane Change Alert with Side Blind Zone Alert and Lane Keep Assist with Lane Departure Warning. The vehicle’s available Side Blind Zone Alert system works with trailers, too.
GM says it will also offer nine exterior colors on the SUV including three all-new colors: Empire Beige Metallic, Cherry Bomb Tintcoat and Darkmoon Blue Metallic.
Both the 2021 Chevrolet Tahoe and Suburban will be manufactured at GM’s Arlington Assembly plant in Texas. They will arrive in Chevy showrooms in mid-2020. Pricing will be announced closer to their official launch next year.
