SPIED: 2020 Chevrolet Tahoe Gets an Independent Rear Suspension
Fullsize SUV Follows Expedition, Sequoia, and Armada into the Modern Age
Thanks to the bold work of our spy photographers, we now know the 2020 Chevrolet Tahoe will finally get an independent rear suspension when it is redesigned. These first photos of the new SUV clearly betray new suspenders, with what looks like a double-wishbone design for the rear axle. Expect the same layout (though perhaps with different tuning and shock options) to appear in the 2020 Chevrolet Suburban, GMC Yukon and Yukon XL, and Cadillac Escalade and Escalade ESV.
The new suspension layout should pay the same dividends in the Tahoe that it does in the Ford Expedition, which has featured an independent rear suspension since 2003. Since there’s not a massive live axle traversing the rear wheels, the passenger cabin floor can be lowered, improving toe room for third-row passengers and easing integration of flat-folding seats. To achieve the latter feature in the current Tahoe, the load floor is artificially raised to meet the seats, compromising total cargo volume and liftover height.
Built off the same T1XX platform as the 2019 Silverado 1500, the Tahoe should feature extensive use of high-strength steel in the body structure, with aluminum reserved for swing panels (doors, hood, and liftgate). We predict the SUV to lose about 400 pounds in the changeover, with a base curb weight just under 5,000 pounds.
Also slated for the Tahoe, as evidenced by the spied vehicle’s dual rear exhausts, is the updated version of GM’s 6.2L V-8. Like the Silverado 1500, expect this engine to be mated to a 10-speed auto and saddled with Dynamic Fuel Management, which will allow the Tahoe to run on as few as one cylinder in light load situations. Plan on seeing DFM appear on the Tahoe’s base engine, a 5.3L V-8 paired to an eight-speed auto.
While General Motors is the last fullsize SUV manufacturer to the independent rear suspension party (Toyota gave IRS to the Sequoia in 2008 and the Nissan Armada has had it since its birth for 2004), it could be the first to offer a turbodiesel engine. Our sources suggest the 3.0L turbodiesel I-6 slated for the Silverado 1500 could make its way into the Cadillac Escalade, and it’s possible the engine could make it to the volume models as well. That’s something we’d love to see. For what it's worth, the Escalade is also slated to get a plug-in hybrid variant, as well as a version of Caddy's new Blackwing twin-turbocharged V-8.
Expect GM’s 2020 lineup of fullsize SUVs to make its first appearance at the North American International Auto Show in Detroit this January.
