Much of what has changed with the 2007 GMC Yukon is found in the details. The overall silhouette remains the same, but the wheel track has been widened (three inches in front, one inch in the rear) for a more aggressive stance and better stability. The Yukon’s front end features a bold new fascia the demonstrates the designers’ attempt at cleaner lines and smaller gap tolerances, bodyside cladding has been removed, the lower door sills now overlay the rocker panels for a cleaner profile, and the tailgate handles have been replaced with hidden release buttons. Adding to the sharper design, standard wheel sizes have increased to 17 and 18 inches, with optional rims as large as 20 and 22 inches. Two-wheel-drive models have been lowered by an inch and four-wheel-drive models dropped 15 millimeters. The Yukon features large, shiny headlight housings with vertically-stacked lamps, while the Chevy Tahoe uses smoked lenses with horizontally-placed lights, and the Cadillac Escalade wears a unique front clip with its own fenders and front doors. Rear barn doors have been scrapped for all models.

Inside is a completely redesigned dash, now featuring smooth shapes, tight tolerances, and none of the 1980’s-era radio and climate controls that have historically plagued GM interiors. It’s a welcome change, though the volume knob we saw on an early production model was conspicuously small. With the new design, cargo capacity has increased by 4.2 cubic feet behind the second row seats, and a new front-row center console offers an amazing 20 liters of capacity.
