2014 Chevrolet Silverado and GMC Sierra introduced

GMC says it's 'considering' an all-electric Sierra pickup

GM loves to talk about its electric future — Cadillac was just announced as the brand's official electric division — but trucks haven't been mentioned as a part of this electric revolution, so far. However, that may be changing. CNBC spoke with Duncan Aldred, vice president of GMC about the potential for an electric GMC Sierra. He replied, "Certainly, it's something we're considering." As the Sierra goes, so does the Chevrolet Silverado, and vice versa. But it would make sense for GM to introduce electrification to GMC first, followed by the Silverado. GMC already gets premium features such as the Multi-Pro tailgate are GMC exclusives, after all. It's also marketed as more high-end and premium, which could help make the cost of an electrified Sierra easier to recoup for GM, and easier to stomach for customers. This electric truck consideration could be in response to Ford's aggressive declaration of an electric F-150 the other day, as well as the electric concept trucks from Rivian and Bollinger. The concepts in particular have generated much excitement for their ridiculous claimed performance and shocking utility. If GMC is only "considering" it, then we imagine the brand isn't too far along the development path, if it's even started. Regardless, it's the most affirmative stance we've seen GM take on total electrification of a full-size pickup truck yet. We asked GMC for confirmation and for any clarification it could provide us on the Sierra's electric future, but a spokesperson responded with, "no comment." Related video:

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.
