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.

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.

2024 GMC Acadia to go big again for third generation

In July, spy shooters caught prototypes of the next-gen GMC Acadia wrapped up tight in camouflage. We couldn't make out any useful aspects but one: The coming third-gen Acadia is larger than the current second-gen. Remember, GMC debuted a smaller Acadia for the 2017 model year, lopping eight inches of length and three inches of width from the first-gen large mid-size SUV to create a smaller mid-size three-row SUV. The new prototypes appeared to show that decision would be reversed, now we have proof thanks to more comments unearthed from GM's recent Investor Day presentations in New York. Caught by GM Authority, automaker president Mark Reuss said, "Alongside the Traverse, we’ll move the GMC Acadia to a little bit different size standpoint. This comes in a little bigger than the old Acadia, so itÂ’s a big transformation for GMC and its part of the market." In a 2016 Automotive News piece about how GMC planned to increase sales volume, AN reported, "One potential avenue: venturing into Jeep's terrain. Industry sources believe GMC is drawing up plans for an SUV based on the same body-on-frame platform that serves as the bones of the GMC Canyon and Chevrolet Colorado midsize pickup. It's in the early stages — it doesn't appear to have been sourced to suppliers yet and the SUV's arrival isn't expected until 2020 or later." The first-gen 2016 GMC Acadia was 200.8 inches long, while a 2016 GMC Canyon Crew Cab with the roughly 5-foot bed was 212.8 inches long. It's thought that truncating the second-gen GMC Acadia to 193.4 inches long and 75.4 inches wide was intended to leave plenty of room for the planned SUV on the Canyon platform. However far that SUV project got, it was reportedly canned in 2018.   Hence an upsized Acadia returns. Reuss' comment about the Chevrolet Traverse could imply what's coming for the GMC, the Chevrolet being 205.9 inches long and 78.6 inches wide. A bigger Acadia could make a better sales proposition against the two-row Terrain, too. The Terrain costs almost $9,000 less than the Acadia and is 182.3 inches long and 72.4 inches wide. It's not clear when GMC plans to show the new Acadia, but the consensus is that it will go on sale for the 2024 model year. Expect an all-new cabin, Super Cruise capability and a front fascia reminiscent of the new Canyon. Powertrain options are a mystery.
