2015 Chevy Tahoe, Suburban and GMC Yukon unveiled

General Motors has today unveiled its new family of fullsize SUVs, including the 2015 Chevy Tahoe, its longer Suburban sibling, and their GMC Yukon, Yukon XL and Yukon Denali cousins. More efficient powertrains, improved aerodynamics, increased connectivity and better overall refinement are what Chevy and GMC say will separate their new SUVs from the current generation.
Sporting a tried-and-true body-on-frame architecture, these full-size SUVs feature platforms that are stronger and offer a wider rear track for "a more planted stance," according to Chevy and GMC. Mounted at the front of each SUV is an EcoTec3 powertrain, which consists of a standard 355-horsepower, 5.3-liter V8 (or a 420-hp, 6.2-liter V8 for the GMC Yukon Denali alone) with direct injection, cylinder deactivation and continuously variable valve timing, that's paired with a Hydra-Matic 6L80 six-speed automatic transmission. The setup is said to be more efficient than before, though official EPA fuel economies for each vehicle are not yet available. To help the powertrain achieve the best possible fuel economy in these 5,000+ pound SUVs, the new styling was developed with aerodynamics in mind. For the same reason, electric power steering also makes its debut in the Tahoe/Suburban/Yukon family.
The front fascias of the Chevy Suburban/Tahoe and GMC Yukon are distinct, but from the base of the A-pillars back, they share most of the same styling cues. This now includes inlaid doors that tuck into the door sills, instead of over them, which improves aerodynamics and fuel economy, and lessens interior noise. The hoods and liftgate panels now are made of aluminum in an effort to reduce vehicle weight. Chevy and GMC also tout that the Tahoe/Suburban and Yukon don't share a single piece of sheetmetal or lighting element with the brands' full-size pick-up trucks.

GM 6.2L V8 claims most powerful light-duty truck engine title

General Motors has officially captured the horsepower crown for mainstream pickup trucks with its 6.2-liter V8. The big mill, available in both the Chevrolet Silverado and GMC Sierra, comes to market with 420 horsepower and 460 pound-feet of torque, handily outdoing its two cross-town competitors, Ram (5.7-liter V8, 395 ponies and 407 lb-ft) and Ford (6.2-liter V8, 411 hp and 434 lb-ft).
The new GM 6.2 will take a bit of an investment, though. Those that want the extra thrust will need to go with either the LTZ or High Country trims from the Chevy, or the SLT and Denali trims from GMC, which are the two highest trim levels for the respective vehicles. Trim levels aside, if you're in the business of towing, GM has you covered. Optioned with the 6.2-liter V8 and the Max Trailering Package, owners will be able to pull 12,000 pounds, a hugely impressive figure.
We still aren't certain as to what sort of economy the new engine will get, but it'll probably be a bad bet for the fuel conscious. As for availability, expect to see the 6.2-liter trucks in showrooms later in the fall.

GMC to get own model not shared with Chevy?

For years, GMC has existed as a brand without a single unique product, reconstituting Chevrolet trucks, SUVs and crossovers with more frosting in exchange for a few extra dollars. The Sierra is a Silverado, the Acadia a Traverse, and the Terrain an Equinox, although admittedly the latter pair are visually differentiated to a significant degree.
GMC could be set to expand beyond its Chevy-based roots, though. During last week's Detroit Auto Show press days, GM's product boss Mark Reuss was asked whether there'd ever be a GMC that wasn't taken from Chevy. "Oh, yes, you will," Reuss told the media. "The health of GMC is astonishingly good from a consideration standpoint." Reuss wouldn't elaborate on what the model could be, although we're quite happy to make some guesses. GMC has its bases fairly well covered, with a mid-size and full-size crossover, as well as a mid-size, full-size and HD pickup. We doubt GMC will be building a family sedan, sports car, or hatchback, so really, the only place we can see the brand going is into a smaller crossover.
Automotive News points out that the most recent small GMC showcar, the 2010 Granite concept (shown above), won't see production according to General Motors. That vehicle likely would have rode on GM's compact vehicle architecture, known internally as Gamma II, which underpins the Chevy Spark and Sonic, as well as the Buick Encore (and its overseas Opel/Vauxhall/Chevy counterparts).
