Today in New York, Chevrolet and GMC unveiled their all new 2015 full size SUV’s. The Chevrolet Tahoe and Suburban, as well as GMC Yukon and Yukon XL get all new sheet metal, underpinnings and considerably upgraded interiors in their first major re-design since 2007.
Both share the new truck architecture that made its debut with the new 2014 Chevrolet and GMC trucks, featuring new frames, suspension, and the more fuel efficient EcoTec engines. Under the hood will be a 355 horsepower 5.3 liter V8 across the board. A 6.2 liter 420 horsepower V8 will be available exclusively in the GMC Yukon Denali trim.
Styling is significantly different for the GMC and Chevrolet models. The GMC gets a more prominent grille with bolder projector beam headlamps. The Chevrolet gets a wider looking grille treatment with a more stacked appearance to the headlamps. The rest of the vehicles are virtually identical save for a few pieces of trim.
Wheels range from 18” all the way up to 22” with various designs for both brands. Bodies get the new inlaid doors which made their debut on the pickups last year. A slick standard rear spoiler hides the rear wiper when not in use. Use of aluminum is increased to save weight too.
Improvements and new features are the hallmark of these new models as styling changes are evolutionary. Inside there are new fold-flat second and third row seats that give a flat cargo floor without having to remove them. In the rear cargo hold there is a new plastic cargo management system, and an available power lift gate made of aluminum to help you get to your stuff. Rear seat passengers can enjoy an optional Blueray / DVD entertainments system too.
The cockpit will now feature standard display audio with an 8” touch screen, GM’s new IntelliLink applications, and available of course with navigation. The instrument panel also has an 8” driver display that can be fully customized with theme and information sets.
The cabin really got a lot of good design attention as you can see from the photos. While the current interiors aren’t bad at all, the new one really raises the game with soft trims and a more expensive look. Its an exclusive dash and instrument panel design not shared with the pickup trucks.
Underneath is a fully boxed frame made of some 75 percent high-strength steel. One inch wider wheels provide a wider track and new electric power steering helps save fuel. A more robust 9.5” rear axle is added with standard auto lock rear differential for better traction and durability.
While EPA fuel economy estimates are not yet released, it is expected these new twins should achieve a small increase in efficiency. The new 5.3 and 6.2 liter V8 engines feature direct fuel injection, variable valve timing, and cylinder deactivation to save fuel while increasing power. A six-speed automatic transmission is also standard across the line.
