2021 Chevrolet Suburban MODEL OVERVIEW


  • Comfortable ride
  • Roomy interior
  • Responsive powertrains


  • Underwhelming interior quality
  • Standard suspension is still truck-like

The Chevrolet Suburban, which has been around since 1935, is one of General Motors' longest running nameplates. Originally a wagon, the Suburban eventually became one of the first SUVs when it adopted the body style in the 1960s and shared its body-on-frame underpinnings with the Chevrolet Silverado. Now in its 11th generation, the Chevrolet Suburban continues to use the same underpinnings as the Silverado pickup. However, the latest version has a new suspension setup to maximize comfort and interior space.

If you'd like the Suburban in a slightly smaller package, try the also-new 2021 Chevrolet Tahoe.

What's New

  • New generation of Chevrolet's largest SUV rides on a new platform, offers more space, and features an independent rear suspension
  • Diesel engine joins the lineup for the first time
  • Off-road-oriented Z71 added as a mid-level trim

What We Think

The 2021 Chevrolet Suburban's size makes it an ideal shuttle or family vehicle (when a minivan is out of the question), which means excellent ride quality is of the utmost importance. Thankfully, the new suspension setup delivers just that, as we initially experienced in the smaller Tahoe. With the available Magnetic Ride Control dampers and adaptive air suspension, the SUV glides over road imperfections and doesn't toss passengers' heads around excessively, even in Sport mode. That said, coil-sprung examples are less settled.

The new Suburban offers significantly more passenger and cargo space than its predecessor; even full-size adults fit in the third row. In terms of interior quality, though, the Suburban falls short of the standard set by the Ford Expedition. That said, it's easy to ignore the interior shortcomings when you're controlling one of the Suburban's excellent powertrains with your right foot; the Duramax diesel/10-speed automatic combo is especially worthy of attention.

Performance and Fuel Economy

The 2021 Chevrolet Suburban's three engine options are shared with the Tahoe.

All 2021 Chevrolet Suburban models are equipped with forward collision warning, pedestrian detection, automatic emergency braking, automatic high beams, and following distance indicator as standard. The Driver Alert package (standard on Premier and High Country models) adds lane keeping assist, lane departure warning, blind-spot monitoring, rear cross-traffic alert, and front and rear parking sensors. Rear pedestrian detection is available as part of the Luxury package on the LT and Z71 grades and standard on the top two trims. Adaptive cruise control is available only on the Premier or High Country variants via the Premium package.

Cargo Space and Interior Room

With all seats in place, the 2021 Chevrolet Suburban has 41.5 cubic feet of cargo space. Total capacity expands to 93.8 cubic feet with the third row folded or 144.7 cubic feet with the second and third rows down. That's significantly more than you'll find in the Tahoe, which offers 25.5, 72.6, and 122.9 cubic feet of cargo space.


The 2021 Suburban features a 10.2-inch touchscreen, wireless Apple CarPlay and Android Auto support, and a 4.2-inch instrument cluster display. LT and Z71 trims get a nine-speaker Bose audio system while the Premier and High Country have a 10-speaker Bose surround sound unit. Higher trims also come with an 8.0-inch instrument cluster and an optional head-up display.
