The 2013 GMC Yukon carries over unchanged except for a new exterior color (Champagne Silver Metallic) and the ability to use powertrain grade braking in normal transmission mode to reduce brake wear when going downhill.
The 2012 GMC Yukon and Yukon XL receive some minor upgrades and equipment. A heated steering wheel is now available on SLT trims (except for 2500 models), and heated front seats are made standard on all SLTs. A third-row screen is added to Yukon XL models with the rear-seat DVD entertainment package, and trailer sway control and hill start assist are added to the StabiliTrak stability control system. The Denali trims gain side blind zone alert as standard equipment.
Essentially mechanically identical to Chevrolet's Suburban, the Yukon XL is on what GMC calls an "all-new" full-size SUV platform. Half-ton 1500 and heavy-duty 2500-series models are available, with rear- or four-wheel drive. The standard engine size is a 5.3-liter V8, available in either gasoline or flex-fuel versions (the latter so it can operate on E85), with 6.0-liter V8s optional. Or, buyers may step all the way up to an extravagant Denali Edition with its class-leading 380-horsepower 6.2-liter V8 and six-speed automatic transmission.
