Redesigned for 2007, the Yukon now stands wider with a lower stance for better handling and ride. Available in either SLE or SLT trim with a 4.8Liter V8 that produces 295HP, and the option of a 5.3Liter V8 that puts out 320HP with the two-wheel-drive, and 310HP with the four-wheel-drive system. The only transmission available is the newly designed six-speed automatic.
