GM confirms 2015 Silverado, Sierra to get 8-speed automatic

When viewed alongside the next Ford F-150 and the Ram 1500, there is one thing that seems to be missing from the Chevrolet Silverado and GMC Sierra. Where the F-150 will rely on turbocharging and aluminum architecture and the Ram sports an eight-speed automatic and an air suspension, the General Motors twins lack a big, calling-card feature. They're very good, very refined trucks, but one could argue that they're not terribly innovative.
And while it might not be as flashy a feature as air suspension or a lightweight skin, the Silverado and Sierra will get their own eight-speed automatic for 2015, a transmission that will be paired with the company's Ecotec3 6.2-liter V8. The new cogswapper will also find its way into the GMC Yukon Denali, but for now, there's no indication why the Cadillac Escalade, Suburban, Tahoe and standard Yukon are being left out.
According to GM, the new gearbox is about the same size and weight as the current Hydra-Matic 6L80 six-speed. By the time the new powertrain combination enters production late this year, the EPA will almost certainly have gotten around to certifying the vehicles' fuel efficiency. Until then, feel free to speculate. The current Silverado with the 6.2 and six-speed auto returns 14 miles per gallon in the city and 20 on the highway. How much do you think the eight-speed will improve those figures? Scroll down for the official press blast from General Motors, and then head into Comments.

GM profits threatened by glut of pickups

Automotive News reports that General Motors may slash production or ramp up discounts in order to deal with an oversupply of pickup trucks. GM currently has more than double the standard supply of pickups, and the vehicles are threatening to dampen the automaker's profits for 2013. Typically, automakers try to sustain a 60- to 75-day supply of vehicles, but GM is currently loaded with a 139-day supply, as of last month. At the end of November, the automaker was sitting on 245,853 units.
The manufacturer says that it will adjust production accordingly before laying any incentives on the profitable pickups. Even so, there's some concern that the inventory swell could hurt the roll-out of the next-generation Chevrolet Silverado and GMC Sierra. GM actually began slowly stepping back production in August, but it's clear the company will take further action as it heads toward the end of the year and into the next. Analysts predict the automaker could reduce pickup manufacturing by nearly half in the first quarter of 2013.
That still may not be enough to keep GM from laying extra cash on the Silverado and GMC Sierra. While the company's incentive spending was down in November compared to the same month in 2011, both the Ram 1500 and Ford F-150 saw double-digit percentage increases in sales last month while the Silverado and Sierra numbers slid compared to a year prior. Incentive spending could help move more trucks and add some balance to the GM inventory surge.

2014 GMC Sierra 4.3L V6 to offer segment-best 305 LB-FT

General Motors has released more information on the 4.3-liter V6 available in the 2014 GMC Sierra. The engine will serve up 285 horsepower and 305 pound-feet of torque, with a six-speed automatic transmission, and giving the V6 Sierra a maximum tow rating of 7,200 pounds in regular cab, short bed four-wheel drive configuration. GM claims that figure is 500 pounds more than the equivalent Ford F-150 equipped with a 3.7-liter V6, and 700 pounds more than the Ram 1500 with its 3.6-liter V6. Buyers can expect to see the 2014 GMC Sierra with the 4.3-liter engine start at $25,085 including destination.
While the engine does deliver more torque than either of its main competitors, it falls short on the horsepower front. The 3.7-liter V6 in the F-150 develops 302 hp while the 3.6-liter V6 in the Ram 1500 yields 305 hp. GM says fuel economy estimates for its newest entry will land later this year.
