For 2020, both the Tahoe and Suburban are available in three trim levels; LS, LT and Premier.
Standard in both SUVs is a 5.3L EcoTec V8 engine producing 355 horsepower and 383 lb-ft of torque. The engine is paired with a responsive 6-speed transmission and a best-in-class V8 highway fuel economy of 22 mpg. For those looking for more horsepower, an available 6.2L EcoTec V8 is available, producing 420 horsepower and 460 lb-ft of torque. The larger engine is paired with a 10-speed transmission to help send the increased power to the wheels. All trim levels are available in either 2-wheel drive or 4-wheel drive, providing impressive handling both on and off road. When properly equipped, the Suburban can tow up to 8,300 pounds; the Tahoe 8,600 pounds--made easier to manage thanks to the transmission's TapShift controls, dedicated Tow/Haul mode and Auto Grade Braking.
Inside, the Suburban and Tahoe continue to excel in ride quality, in keeping with previous models, but their interiors have been upgraded with new sharper, more modern instrument panels. Most versions get an 8-inch touch-screen audio system that also conceals a hidden dash compartment. Chevy claims the center console compartment is large enough for a laptop or iPad.
The base LS trim models include tri-zone automatic climate control, power windows, locks and mirrors, a rear-vision camera system, Rear Park Assist sensors, GM's OnStar concierge and convenience system (including six months of the Directions & Connections plan), 8-inch infotainment touchscreen and an audio system that includes Apple CarPlay, Android Auto, HD Radio and SiriusXM satellite radio compatibility.
Moving up to the LT trim adds leather upholstery, heated front seats, a power liftgate, a heavy-duty locking rear differential, the enhanced MyLink touch-screen connectivity, 9-speaker Bose sound system and the Enhanced Driver Alert Package. This package includes forward collision alert, lane keep assist, low speed forward automatic braking, IntelliBeam headlamps and safety alert seat. Additionally, the LT adds the potential to option up to items such as keyless entry with push-button start, full Front and Rear Park Assist, a sunroof, a navigation system and a rear-seat entertainment system with dual screens and Blu-Ray compatibility.
At the top of the lineup, the Premier includes most of those aforementioned items as standard except for the rear-seat entertainment and power sunroof, which are also optional. The Premier gets loads of meaningful upgrades, including 20-inch wheels, keyless entry, heated side mirrors, upgraded trims, fog lamps, the Magnetic Ride Control suspension, heated and cooled front seats, power-folding second-row and third-row seats and Bose Centerpoint surround audio.
The roomier Suburban is the way to go for three rows of seating. The second row can be specified with either a 60/40-split bench seat or with dual bucket seats. A power-folding arrangement is available. The Suburban provides considerably easier entry to the third row, thanks to wider door openings.
All Tahoe and Suburban models continue with sturdy body-on-frame construction, although the frame has been strengthened; there's a wider track that aids stability; and additional noise-and-vibration damping measures have been added to make the cabin especially quiet. At the top Premier trim level, it comes with magnetic ride control, which can 'read' the road and constantly adjusting the way that the suspension responds, softening it for bumpy, pitchy surfaces or firming it up for quick emergency maneuvers. All of these models now include precise, variable-assist electric power steering, as well as 4-wheel disc brakes with Duralife brake rotors which GM claims, last twice as long as ordinary ones.
Abundant Seating And Cargo Space
Versatility And Toughness
Strong Towing Capacity
Comfortable, Refined Ride
Relatively Fuel-efficient Engines
The Chevrolet Suburban and Tahoe remain unchanged for 2020, save for a couple of new optional 22-inch wheel designs for this year.
The Suburban and Tahoe are by-far the best-selling models in their class, and they're tough rivals for the Ford Expedition, Toyota Sequoia and Nissan Armada, among others. These two Chevy models are closely related in most ways, but the Suburban is 14 inches longer in wheelbase and 20 inches longer overall than the Tahoe. The larger dimensions results in a significantly larger third-row seat than in the Tahoe--as well as easier access to it, as well as more cargo space.
Compared to other full-size SUVs, the Chevy Tahoe and Suburban stand out for their ride quality and efficient engines. They're also very rugged and versatile, and can be outfitted for off-road toughness, tow ability or interior luxury as needed. Chevrolet claims that the Tahoe is the most fuel-efficient model in the full-size SUV class, thanks to direct injection and active fuel management and cylinder deactivation.
