This is almost Jalopnik Reviews: Mercury Mountaineer Part 2: Attack of the Clones. Okay, this time it's a GMC Yukon Denali, clone to the Chevrolet Tahoe and Cadillac Escalade. Lest you think this is a Tahoe with a badge slapped on it instead of the "professional grade" product you've come to expect from GMC, know that all of the sheet metal in front of the windshield is unique to the Yukon. The upgrade from everyday Yukon to the chrometastic Denali (even the headlights are shinier) comes with a 380-horsepower 6.2-liter V8 that is unavailable in the Tahoe. This is the same engine found on the Escalade, although the 'Slade has an output of 403 hp to keep it on top of the corporate pecking order. How's that for brand strategy?
