Although not much larger than their predecessors, the cargo capacities of Chevrolet’s full-size utility vehicles increase by 66 (Suburban) and 19 percent (Tahoe). The Tahoe also gains up to 10 inches of third-row legroom thanks to a fore and aft sliding second-row. A 10-speed automatic transmission replaces the six-speed automatic and there’s a new 3.0-liter inline-six-cylinder turbo-diesel that makes 277 horsepower and a stout 460 pound-feet of torque. The Tahoe and (the longer) Suburban are built off an new chassis with an equally new independent rear suspension. An adaptive air-ride suspension with rear load leveling is optional.
