The 2018 Chevrolet Suburban sport utility vehicle is powered by a 5.3-liter V8 engine producing 355 horsepower and 383 lb. ft. of torque. The power is distributed to the rear wheels via a six-speed automatic transmission. An all-wheel-drive option is also available for the auto. With a full-sized SUV that is designed to carry people and cargo, the acceleration suffices to haul the load without much urgency. Despite its massive load capacity, the Suburban can reach 60 mph in a little over seven seconds. Definitely, not the sportiest in its delivery but the engine has enough oomph to move people and cargo around. Handling is far from being light-footed but the stability is there even when brought to the limit of its cornering abilities. A light steering that is lacking road response is common among bigger SUVs and the Suburban is no exception. Fortunately, it handles accurately and the effort is weighted just right. With a firm pedal that commands the brakes with ease, there is minimal excessive movement even under intense braking. The distance it took to brake from 60 mph is 131 feet, a few more feet than most of its competitions in the full-size SUV category. Despite that, the bite of the calipers is linear in its application.

Stepping up into the cabin is aided by running boards and the front and rear doors open up a spacious entryway. Loading cargo or even crawling through the trunk door can be a bit of a hassle because of the taller floor height relative to the ground. The first and second rows are very roomy but the third row feels tight given the raised knees in its seating position. For all trims, there is seating for seven people but opting for the bench style front seats allows for one more passenger. The first and second row of seats are comfortable but are firm enough to not induce aches. The third row, however, isn’t as padded and the cushion is flat. Unfortunately, the second row does not slide to and fro to allow more leg room. The suspension has been set up to provide a ride quality that is stable and can absorb smaller rough patches with ease. Bigger bumps along the road can be more interruptive and can be shaky for passengers. External noise is greatly reduced whether at idle or highway speeds, creating a quiet and relaxed atmosphere inside.
Behind the third row of seats is 39.3 cu. ft. of space, and folding them down opens up 76.7 cu. ft. of space. Upon folding down the second row of seats, there is 121.7 cu. ft. of space for loading cargo.
