Though the overall shape looks familiar, enhancements on the 2007 GMC Yukon XL are visible in the details. The wheel track has been widened for a more aggressive stance and better stability, the front end features a bold new fascia, 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. Standard wheel sizes have increased to 17 inches (18’s on the XL Denali) with optional rims as large as 20 inches, and tall, shiny headlight housings that, unfortunately, lack character when compared to the sporty lenses on the new Chevy Suburban. 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.
