Chevy Silverado, GMC Sierra 4.3-liter EcoTec3 V6 nets 18 mpg city, 24 highway

There is no doubting that fuel economy has become an important factor in the highly competitive fullsize truck market, with the Ford F-150 EcoBoost V6 and Pentastar V6-powered Ram 1500 setting quite a precedent in recent years. Now it's General Motors' turn. The General has just announced that the new base V6 used in the 2014 Chevrolet Silverado and GMC Sierra 1500 models will return an EPA-estimated 18 mpg city and 24 mpg highway in two-wheel drive trim, regardless of cab configuration.
While these figures don't go so far as to earn GM any "best-in-class" fuel economy claims (thanks to the 25-mpg Ram 1500 HFE), this new 4.3L EcoTec3 V6 does edge the F-150 and Toyota Tundra while boasting best-in-class numbers for torque, payload and towing capacity among six-cylinder rivals. This all-new engine produces 285 horsepower and 305 pound-feet of torque, and it gives the 2014 Silverado and Sierra the highest towing rating among standard V6 models with a 7,200-pound towing capacity - besting the Ram by 700 pounds, the base F-150 by 1,100 pounds and coming within 200 pounds of the V8-powered Nissan Titan.

2016 GMC Sierra All Terrain X is cool but no Raptor threat

If you want a brutish off-roader from Ford or Fiat Chrysler Automobiles, you're spoiled for choice. There's the F-150 SVT Raptor, the Jeep Wrangler, and the Ram Rebel and Power Wagon. But since General Motors killed the Hummer brand, it's been without any real competitor to those trucks. The new, special edition GMC Sierra All Terrain X is not going to be that vehicle, but it's close enough to be worth a look. The oft-overlooked Sierra All Terrain's off-road suspension and Eaton locking rear differential give it some real trail credentials. The All Terrain X builds on both with cosmetic and performance upgrades. For most owners, the big draw will be the brawnier 5.3-liter V8. Fitted with a performance exhaust, it should deliver a meatier tone, and according to GMC it bumps output up from 355 to 365 horsepower. The other big performance upgrade comes from the tires, knobby Goodyear Wrangler DuraTrac MT mud-terrain-rated things. The tires and their accompanying 18-inch black aluminum wheels are nice touches. Cool as the All Terrain X might be, it strikes us as an odd strategy for the GMC brand. For one, the trail-ready tires and performance exhaust of the All Terrain X don't seem to fit into the more premium market position that GMC occupies. Moreover, Chevy already has an off-road-oriented pickup in the new Colorado Z71 Trail Boss. Visual upgrades like the black bed-mounted sport bar, LED off-road lights, blacked-out accents, and the 18-inch wheels, the look of the All Terrain X is more in line with the Colorado Trail Boss theme. It's just our two cents, but it seems like attaching the All Terrain X's aesthetic to the Silverado would have been a stronger strategy, and would give Colorado buyers a larger off-road-focused truck to aspire to. You can look for the special edition All Terrain X in GMC dealers this spring, with prices to be announced closer to the on-sale date. Read on for the official press release from GMC.

GMC considers adding more vehicles to broaden product line

GMC is considering expanding its product portfolio in the next 10 years to allow it to reach more potential buyers and grow sales, a top executive said Monday. The small and midsize sport-utility-vehicle segments are two possibilities, said Duncan Aldred, GMC sales and marketing vice president. He also said GMC won't make a car, preferring to reinforce its reputation as a maker of trucks and SUVs. "There's plenty of opportunities even if we define ourselves as a we do as a truck and crossover brand," he said. He wouldn't comment on the possibility of adding a Jeep Wrangler-fighter, though rumors have swirled for months that GMC is considering a product to compete with the iconic off-roader. "I can't confirm that ... everything's on the table," he said. He also said that it's possible GMC could get a unique set of underpinnings – all of its vehicles share platforms that are also used by Chevrolet – but it's not needed to differentiate his brand. "I'm very happy sharing underpinnings and everything else," he said. "All of the good-performing automakers do that." Speaking to journalists at a roundtable at General Motors headquarters in Detroit, Aldred said GMC received an investment from GM that is double what the brand has historically spent to fund its growth plans. Advertising spending alone will increase 50 percent this year compared with 2014. The brand rolled out a new ad campaign on Monday, called "Precision," that will underscore attention-to-detail and the premium features of GMC vehicles. Two of the commercials have a sporting theme, and the third focuses on modern menswear. GMC called it a "contemporary interpretation" of the brand's traditional positioning, and it will also continue to use its long-running "Professional Grade" tagline. The premium positioning of the ads come as buyers are increasingly outfitting their trucks as near-luxury vehicles. The percentage of buyers opting for the top-end Denali trim has increased from 17 percent in the middle of 2014 to 21 percent now. The goal is to get Denali to make up 25 percent of GMC sales by the end of 2017, Aldred said. Spurred by the higher Denali take-rate, the brand's transaction prices leapt by $3,000 last year. "It's [Denali] really kind of this jewel in the crown," Aldred said. GMC sales increased 11.3 percent in 2014 to 501,853 units, making it GM's-second-best-selling brand behind Chevrolet.
