The all-new models will ride on the GM T1 body-on-frame vehicle platform, the same architecture used by the 2019 Chevrolet Silverado 1500 and 2019 GMC Sierra 1500. In addition, the 2021 Chevrolet Tahoe and Chevrolet Suburban are expected to come equipped with aluminum swing panels (hood, trunk, doors, etc.), which will pair nicely with the T1 platform to help shed some serious weight compared to the current models.
As we reported previously, the new SUVs will both come equipped with a new independent rear suspension setup, either as standard equipment or as an available option. Not only will this give the 2021 Chevrolet Tahoe and Suburban significant improvements to both ride and handling, but it will provide the SUVs mechanical parity with rivals like the Ford Expedition.
As for what will be mounted under the hood, we expect the 2021 Chevrolet Tahoe and Suburban to offer the turbocharged 2.7L L3B inline four-cylinder, and/or the naturally aspirated 5.3L L84 V8. As for cog-swapping duties, we expect those to be handled exclusively by the new GM 10-speed automatic transmission.
Per usual, the next-gen models will also come with completely new designs for both the exterior and interior. As we covered previously, these will come with an “exceptional attention to detail” that includes new fascia and lighting treatments, plus improvements to third-row seating. What’s more, the front ends will come with front air curtains that will make the SUVs more efficient with the go-juice.
