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.

2017 GMC Acadia starts at $29,995

The 2017 GMC Acadia has a lower price in addition to its smaller size and 700-pound weight loss. The latest model starts at $29,995 (including $925 destination) when it arrives at dealers this spring, which is $1,905 less than last year's base version. That low price is just for the front-wheel-drive only SL trim, but there are savings throughout the 2017 lineup. The least expensive all-wheel drive version comes on the SLE model for $35,375, versus $37,100 last year (after $925 destination). The top-spec all-wheel drive Denali now costs $47,845, compared to $50,815 for the 2016 version. You can check out the MSRP for each trim in the release below. The new All Terrain model costs $40,040 and gets a more sophisticated all-wheel drive system with an active twin clutch. GMC claims the layout improves performance in wet, snowy and icy conditions. However, the trim is only available in five-passenger configuration, and storage bins in the floor replace the third-row seat. The 2017 Acadia price is also competitive with some challengers in the segment. For example, a base 2016 Honda Pilot is more expensive at $31,045 (after $900 destination), and the top Elite is $47,470, which is barely cheaper than the Denali. A base 2016 Ford Explorer is more costly at $31,995 (after $945 destination), and the Platinum for $53,915 is several thousand more than a Denali. The latest Acadia offers customers a bounty of tech and efficient powertrains. The IntelliLink infotainment system has support for Apple CarPlay and Android Auto, and there're available safety systems like front pedestrian braking and a surround view camera. Most models come with a 2.5-liter four-cylinder, which GMC estimates gets 22 miles per gallon city and 28 mpg highway with front-wheel drive. A 310-horsepower 3.6-liter V6 offers an estimated 25 mpg highway for front-wheel drive models. Both powertrains use a six-speed automatic.

GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.
