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 interior has a redesigned dashboard and improved seats. It still retains its 9-passenger seating availability, which is available on LS and SLE models only. LT2 and LT3 models have leather seating and available 6-, 7-, and 8-passenger seating. A Z71 package was 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. The Suburban LTZ comes standard with a DVD player and a GPS navigation enhanced touchscreen radio. 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 premium interior package that includes tri-zone climate control and handy features like Bluetooth and rear audio controls. Additionally, radios that are standard in all 2010 trims got a USB port, allowing for music to be played from auxiliary devices through the radio, as well as charging other small electronics. Side blind zone alert became an option on LT and standard on LTZ. The 6.0-liter engine in the 2010 models will also be flex-fuel capable. Minor front end changes including a slightly raised front bumper and side torso airbags were also made standard for 2010. In February 2010, Chevrolet unveiled a 75th-anniversary edition of the Suburban, which had 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 5.3-liter and 6.0-liter engines carried over, and a new 6.2-liter Vortec V8 was added for the Yukon XL Denali. The 8.1-liter engine was dropped. For the 2011 model year, the Suburban will add three new exterior colors to the lineup: Mocha Steel Metallic, Green Steel Metallic, and Ice Blue Metallic. The trims will also get an updated modification, with the rear audio system, Bluetooth, floor console/storage area,
