The eleventh generation Suburban and Yukon XL were unveiled at the 2006 Los Angeles Auto Show in January for the 2007 model year. Production of the redesigned GMT900 Suburban and Yukon XL began at Janesville Assembly and Silao Assembly in March 2006, with the vehicles arriving at dealerships in April.
The new models were redesigned with more modern, less boxy styling, already seen on the previously released 2007 Tahoes and Yukons. The exterior features a more aerodynamic shape, made partly by a steeply raked windshield angle. The new design has less drag than previous models, making it more aerodynamic.
The interior has a redesigned dashboard and improved seats. It still retains its 9-passenger seating availability, which is available on LS models only. LT2, and LT3 models have leather seating and available 6-, 7-, and 8-passenger seating. There is a Z71 package available on LT2 and LT3 models which includes two-tone leather seats. All Mexican-built Suburbans including the 9-seat models offer the special two-tone leather seating used by the Z71.
For the 2010 model year, in which U.S. News & World Report ranked it as the number one affordable large SUV, the Suburban added a new premium interior package that includes tri-zone climate control and handy features like Bluetooth and rear audio controls. In addition, radios that are standard in all 2010 trims get a USB port, allowing for music to be played from auxiliary devices though the radio, as well as charging other small electronics. The 6.0L engine in the 2010 models is flex fuel capable. Minor front end changes including a slightly raised front bumper and side torso air bags were also made standard for 2010.
In February 2010, Chevrolet unveiled a 75th anniversary edition of the Suburban, which will have the LTZ trim with white diamond tricoat exterior paint and cashmere interior, along with standard 20-inch chrome-clad wheels, revised roof rails, integrated navigation radio, XM Satellite Radio, Bluetooth phone connectivity, rearview camera, rear park assist, remote starting, adjustable pedals, and leather upholstery with heated/cooled front seats. Chevrolet says that the anniversary edition will be limited to 2,570 units because of the amount of white diamond paint GM can procure.
The 5.3L and 6.0L engines carried over, and a new 403 horsepower 6.2L Vortec V8 was added for the Yukon XL Denali. The 8.1L engine was dropped.
For the 2011 model year, the Suburban adds three new exterior colors to the lineup: Mocha Steel Metallic, Green Steel Metallic, and Ice Blue Metallic. The trims get an updated modification, with the rear audio system, Bluetooth, floor console/storage area, wood grain interior, luggage rack rails, body-color exterior door handle/mirror caps and premium-cloth front bucket seats now standard on the 1LS trim, and chrome recovery hooks, two-speed transfer case, and 20-inch chrome wheels standard on its 1LZ 4WD models. In addition, the trailering package features the trailer brake controller as a standard on all trims.
For the 2012 model year, trailer sway control and Hill Start Assist become standard on all trims, while the LTZ trim added a heated steering wheel and Side Blind Zone Alert as a standard. Also, the LT1/2 options for the Suburban and SLE1/2 and SLT1/2 options on the Yukon XL were discontinued, leaving the Suburban with only a LS, LT and LTZ trim and the Yukon XL with a SLE and SLT trim. On March 30, 2012, GMC celebrated its 100th anniversary by releasing a special edition of its Yukon XL, offering a Heritage Edition trim package. This would also be the final year that three colors, Graystone Metallic, Gold Mist Metallic and Blue Topaz Metallic, would be offered, along with the all season blackwall P265/65R18 tires.
For the 2013 model year, two new colors were offered: Champagne Silver Metallic and Blue Ray Metallic (extra charge). Also new is Powertrain Grade Braking, normal mode. The 2013 arrived for Chevrolet dealers in June 2012. The 2013 model was rank 10th among the top ten family vehicles by Kelly Blue Book in November 2012.
