The 2018 Suburban’s truck-style frame allows it to tow up to 8,300 pounds, while its standard 5.3-liter V8 manages the immense weight surprisingly well. It also delivers a smooth ride, even on rough roads, although minimal feedback comes through the steering.
But its best attribute is also the source of its biggest flaw, as that body-on-frame underpinnings result in truck-like handing. While other SUVs and crossovers can zip through corners in more car-like fashion, the Suburban is distinctly truck-y in this sense, with lots of roll, squat, and dive. It feels cumbersome, and every bit like a big truck.
While its six-speed automatic transmission is plenty capable and well-tuned, it is getting long in the tooth compared to today's nine- and 10-speed gearboxes.
