Narrow year range (drag arrows to filter):
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.
New for 2010 is OnStar 8.2 with long range remote and traffic control, a center console-mounted USB port and enhanced battery charger for some handheld devices. Under the Yukon's hood, the 5.3-liter V8 is now E85 compatible, while the big Yukon Denali's 6.2-liter V8 gains Active Fuel Management cylinder deactivation. Other mechanical changes include a new 3.08 rear axle on Denali for improved fuel economy and an available two-speed transfer case on four-wheel-drive models.
Content levels increase across the board with a new six-speed transmission standard on all trims. New options include Bluetooth hands-free communication, a rear back-up camera with rearview-mirror view screen and a third-row DVD system. Exclusive to the Denali are optional heated and cooled seats and the Side Blind Zone Alert system.
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.
