The 2013 Suburban carries over with minimal changes. Aside from new exterior color choices, the biggest new feature is that powertrain grade braking, previously used only in tow/haul mode, now works in normal transmission mode. The feature slows the vehicle on steep descents using engine torque, which can reduce brake wear.
The 2012 Chevy Suburban SUV receives a new navigation radio option, while the standard StabiliTrak now includes trailer sway control and hill start assist. The LTZ trim gains a heated leather-wrapped steering wheel and side blind zone alert, while the LT trims gains heated leather seats.
Redesigned for 2007, Chevrolet's Suburban is powered by a new family of V8 engines. Built on GM's new full-size SUV architecture, it's capable of hauling more passengers and cargo than anything in its segment. Cousin to the comparably-redesigned GMC Yukon XL and Chevrolet's own Avalanche SUV/pickup, Suburbans also are related to the shorter full-size Tahoe sport-utility. As before, Suburbans come with two- or four-wheel drive, in regular 1500 or heavy-duty 2500 models. Depending upon the model, a variety of V8 engines are available, of 5.3-liters and 6.0-liters.
