The freshened Suburban is an extremely functional, comfortable, and quiet large three-row SUV. This American icon is the answer for those who need seven- or eight-passenger capacity, cavernous space, and the ability to tow a boat or camper.
The standard 5.3-liter V8 engine delivers ample power at any time, along with a satisfyingly muted burble. The smooth-shifting 10-speed automatic transmission is well-matched to the engine, providing downshifts in a timely manner when the driver is looking for more power. This big rig manages to romp from 0-60 mph in 7.6 seconds, which isn’t bad considering its size and weight. The engine stop/start system, intended to save fuel at stoplights, fires back up quickly and unobtrusively. Fuel economy, though, is only 16 mpg overall, which isn’t any better than the previous generation.
The new independent rear suspension pays dividends by giving the Suburban improved ride and handling, and even greater interior room. The standard suspension absorbs bumps and rough pavement effectively, but we prefer the adaptive suspension that comes on the Premier trim, which ensures a steadier ride while also giving more responsive handling. Still, there is no escaping that this massive vehicle can be a handful to drive and park in tight urban areas.
It's a tall step up into the Suburban’s cabin for kids and shorter adults, though the standard running boards help mitigate the climb. The interior is stunningly quiet, as hushed as many luxury sedans, and the front seats are wide, roomy, and supportive. The two captain's chairs for the middle row are generously sized, and even the third-row has enough headroom for adults, though its low proximity to the floor results in very little leg support.
Most of the controls are easy to use, but there are a few quirks, such as having to interact with the new 17.7-inch center infotainment screen just to reset the trip computer. We also found it puzzling that the Suburban places the wiper controls on a stalk on the left of the steering column, rather than the right, as is common. Because of this setup, it's too easy to mistakenly activate the windshield-wiper mist-clearing or spray functions when using the turn signal.
There are small-item storage spaces everywhere you look, and the large, two-tier center armrest can serve as a desk for a laptop.
The Suburban’s unusually tall hood compromises forward visibility—a particular concern in busy, urban areas where all that metal can easily obscure small pedestrians. The Suburban’s cameras and sensors help when parking, but drivers shouldn’t solely rely on them.
Forward collision warning (FCW) and automatic emergency braking (AEB) with pedestrian detection, lane keeping assistance and lane departure warning are standard. For 2025 blind spot warning and rear cross traffic with braking are standard.
