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.

2014 Chevy Silverado priced from *$24,585, V8 gets better economy than Ford EcoBoost V6

Chevrolet has thrown down the next hand in the pickup truck poker wars and revealed at least a couple of potential aces - depending on which numbers matter most to you. The 2014 2014 Silverado 1500 with its 5.3-liter EcoTec3 V8 gets 335 horsepower and 383 pound-feet of torque, is mated to a six-speed automatic, can tow 11,500 pounds with the optional Max Trailer Package and costs the same as the outgoing Silverado, $24,585 (*including $995 destination fee). Chevy says the Silverado also stands atop the fuel economy charts when comparing any competitor with a V8 engine - and some competitors with V6 engines. The two-wheel drive model returns 16 miles per gallon city, 23 mpg highway, 19 mpg combined in two-wheel drive guise and 16 mpg city, 22 mpg highway and 18 mpg combined as a four-wheel drive.
For context around those numbers, the most fuel efficient V8-powered 2013 Ford F-150 pickups lose about two mpg in every metric compared to the Silverado, the 3.5-liter V6 EcoBoost returning 16 city, 18 highway and 22 combined in two-wheel drive. However, that EcoBoost does have 365 hp and 420 lb-ft of torque. You can get a Ram 1500 with a 3.6-liter V6 that gets 25 mpg highway, but it has 305 hp and 269 lb-ft of torque. The 2013 Ram with the 5.7-liter Hemi V8 and its 395 hp and 407 lb-ft drops one mpg in every category to the Silverado. Its tow rating is 200 pounds beyond its nearest competitor, the F-150 with the Max Trailer Tow Package.
Elsewhere, the new Silverado gets a quieter cab with a redesigned interior, a new bed with improved load-management possibilities, disc brakes all around, tweaked steering and suspension, along with free standard scheduled maintenance for two years or 24,000 miles.
