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's fullsize SUVs boost highway mileage by nearly 10 percent

We met the redesigned 2015 versions of the Chevrolet Suburban and Tahoe, and the GMC Yukon and Yukon XL at the 2013 LA Auto Show. Improved gas mileage numbers have been announced to go along with the improved exteriors and interiors, with city mileage improving by seven percent and highway mileage going up by nearly ten percent; you'll now get 16 miles per gallon in the city and 23 on the highway.
The only applies to models with the 5.3-liter engine, though, not the premium Yukon Denali and Yukon XL Denali SUVs with the 6.2-liter motor. Still, the 5.3 gets you more power than previously, with 355 horsepower and 383 pound-feet of torque underfoot, on top of the improved fuel economy numbers. The 6.2-liter sticks with official mpg ratings of 15 highway, 21 city. There's a brief press release below with words straight from the horse's mouth.

GM announces six new recalls, covering 3.5 million vehicles

General Motors has just initiated another crushingly large recall, this time affecting some 3.36 million vehicles built between 2000 and 2014 and sold in the US, Canada and Mexico. Once again, the issue surrounds the cars' ignition switches, which can be kicked out of the run position if they're carrying extra weight or if they experience a "jarring" event. In this particular case, though, GM will modify the keys, rather than the ignition itself.
A four-by-six-millimeter hole will be drilled into the key, which will more safely accommodate the weight of the key ring. As is usually the case, the work will be done free of charge. The recalled vehicles include the 2000 to 2005 Cadillac Deville, 2004 to 2005 Buick Regal LS and GS, 2004 to 2011 Cadillac DTS, 2005 to 2009 Buick Lacrosse, 2006 to 2008 Chevrolet Monte Carlo, 2006 to 2011 Buick Lucerne and 2006 to 2014 Chevrolet Impala. Only the Impala is still in production, and even then, it's only sold to fleet companies.
According to an official statement from GM, there have been eight crashes and six injuries due to this latest issue. As if this isn't a dire enough blow for GM, the company has announced five smaller recalls, covering 165,000 vehicles.
