Specs at a Glance


Two of the most powerful full-size SUVs on the road today, the Chevy Tahoe and Chevy Suburban are built for hauling, family transport, and rugged everyday transportation. Both are built on a similar chassis but aimed at slightly different markets. They both come equipped with three rows of seating, cavernous interior space, and significant amounts of cargo room. Fans of towing will appreciate the vehicles' impressive towing capacity and powerful engine options; Chevrolet have taken it upon themselves to offer the larger 6.2L V8 for the Chevy Tahoe this year, a welcome addition to the model lineup.

The Chevy Suburban and the Chevy Tahoe both come equipped with a 5.3 V8 as standard, making 335 hp and 373 lb-ft of torque. This is the traditional Ecotech engine that has been found in Chevrolet SUVs and certain trucks for several years now. It's a reliable workhorse engine that offers ample acceleration even under load, decent fuel economy, and enough power for passing on the freeway if necessary. This base engine is mated to a 6-speed automatic transmission, once again a reliable carryover from last year's models. This gearbox includes a tow/haul mode that will shift the gear ratios appropriately for hauling large loads that require more finesse in engine power. When loaded with the optional 6.2L V8, the Chevy Tahoe comes equipped with Magnetic Ride Control to help smooth out bumps in the road, but both vehicles' standard suspensions give a comfortable ride on long journeys.

The real highlight of the 2018 Chevy Tahoe is the addition of the 6.2L V8 engine option. This 420 hp behemoth is both faster and more responsive than the standard 5.3 V8, but trades that power for a minor dip in fuel economy.

Both vehicles will haul up to 8,300 lbs. when properly equipped, making these Chevrolet models one of the highest rated towing SUVs on the market today.


Echoing the days of SUV yore, the Chevy Suburban and the Chevy Tahoe both feature the familiar box shape recognizable as a full-size SUV. Large and imposing, it's hard to mistake these for anything but American-made SUV muscle.

Some of the lines have been smoothed out on both models, with an attractive front-end grill that immediately brands these as Chevrolet vehicles. The Suburban is noticeably larger than the Tahoe, providing more space for family and cargo hauling, with a wheelbase of 130 inches, dwarfing the Chevy Tahoe's already impressive 116 inches. The Chevy Suburban also adds an additional 20 inches of length onto the end of the Chevy Tahoe, coming in 224 inches at the rear-bumper, with the Tahoe being a slightly shorter 204 inches.

This means the Chevy Suburban, while larger on the road, also includes more interior space for cargo and people. Both vehicles are truly cavernous on the inside, with plenty of room for everyone, but buyer's looking for that bit of extra room will want to consider the Suburban for its extra length.


The Chevy Suburban and the Chevy Tahoe feature nearly identical 8” center-mounted infotainment centers, with the same software and connectivity options for phones, both Apple and Android. There's 5 USB ports for charging or connecting mobile devices, wireless charging options, and optional OnStar LTE WiFi connectivity. Both vehicles feature a wealth of safety options, interior tweaks, and aesthetic choices.

Some notable standard and optional safety features for this year include automatic forward breaking, collision alert sensors, a rear vision camera for backing up, and a safety alert driver seat. Additional extra safety features include lane change alert, blind spot monitoring, and a rear cross-traffic alert sensor. Both vehicles also feature “Teen Driver” mode, allowing parents to set limits on certain vehicle features and monitor driving behavior to better teach good driving habits to new drivers.
