GMC Acadia goes big again? Spy photos show next-gen prototype

GMC is testing what looks a lot like a new full-size SUV, signaling the likelihood that it will return to full-size segment after the current generation has run its course. GM downsized the Acadia for the 2017 redesign, carving nearly 10 inches off its length and 3 inches from its girth. For the next generation, it appears that script will be aggressively flipped.  The hierarchy of GM's unibody family SUVs was already a bit wonky before the Acadia's 2017 redesign, and continues to be now. While it would be logical for the Chevrolet Traverse, GMC Acadia, Buick Enclave and Cadillac XT6 — all three-row crossovers — to be different skins on the same fundamental chassis, that's not actually the case. The Acadia is a full foot shorter than either the Traverse or Enclave, with the XT6 falling in between. Based on these photos, that will no longer be the case when the new GMC Acadia debuts. Since the current one went on sale in 2016 as a 2017 model, it's about due for a replacement.  We can't see much beyond basic proportions here, but those tell a clear story. It's pretty obvious that the hood on the prototype is wider and sits higher than on the current car, with perhaps less slope to the now-wider nose. We can also see the faintest impressions of creasing on the flanks, likely leading to the same broad, angular hip treatment present on the current car. Viewed side-by-side, we can see a little more front and rear overhang. There's no obvious hint of substantially longer wheelbase here (the rear doors line up almost perfectly), so we're probably looking at something that is wider but not necessarily much longer.  In any event, we shouldn't have to wait too long to find out exactly what GM has in store for its "Pro" brand.  Related video: This content is hosted by a third party.

2014 Chevy Silverado details continue to dribble out

PickupTrucks.com has gotten its hands on a few more details concerning the 2014 Chevrolet Silverado and the 2014 GMC Sierra. General Motors held a conference call on the two trucks, allowing Jeff Luke, executive chief engineer for both, to answer a few questions. Luke said truck buyers are largely concerned with power and fuel economy, and as such, GM will continue to explore new methods of providing both. That may translate into any number of drivetrain permutations, including light-duty diesel engines, eight-speed transmissions or even a twin-turbocharged V6.
What's more, both the 2014 Silverado and its GMC twin will boast a tow rating of 11,500 pounds, but only when equipped with a max-trailering package. Without that special package, the rating drops to 10,200 lbs for regular cabs and 9,700 lbs for crew cabs. Buyers will no longer be able to opt for a 4.10 gear ratio.
We're also excited to hear that GM plans on making the Z71 package into something more than just a few a stickers. While Luke didn't go into details, PickupTrucks.com says "it will get significant improvements in the future." Head over to the site for a quick rundown of the call's highlights.

GM ending stop-sale order on heavy-duty trucks

General Motors responded to an inquiry from Autoblog regarding a stop-sale order on its full-size heavy-duty pickup trucks. Here's GM's official statement. GM is committed to building the highest quality products possible. We paused delivery on a small number of HD pickups with the 6.6 liter Duramax engine last week to finalize an investigation into a potential quality issue. The investigation has been completed and the stop sale will be lifted for the small number of vehicles at dealerships.Customers can be assured GM’s heavy duty pickups are covered by a 5 year/100,000 mile powertrain warranty. The original article continues below. General Motors has reportedly sent its Chevrolet and GMC dealers a stop-sale order that applies to some examples of the 2022 Silverado HD, the 2022 Silverado MD, and the 2022 Sierra HD. The units affected by the stop-sale order may develop an engine-related problem. Citing anonymous sources, website GM Authority wrote that the Duramax 6.6-liter turbodiesel V8 in the affected trucks can hydrolock, which means liquid could enter the cylinders and cause a substantial amount of damage. The report does not specify where the liquid would come from; hydrolocking can happen by driving through a deep puddle of water, for example, but a large amount of coolant can cause it as well. The publication adds that the stop-sale order was assigned internal reference number N222362910. It also notes that the trucks included in it can't be sold, delivered to buyers, traded with another dealer, sent to auction, or even used for demonstration purposes until further notice. Earlier in April 2022, GM Authority reported that General Motors planned to buy back an unspecified number of Silverado HD and Sierra HD trucks due to quality-related issues with the 6.6-liter V8. Details about the problems experienced by customers haven't been released; all we know is that each truck will be replaced, though the replacement may not have the same equipment due to the ongoing chip shortage.
