2018 GMC Acadia with 'Christmas Aero' modification gets in the wind tunnel

Tis the season of "Big" - big cheer, big parties, big bowls of eggnog, big decorations, and when it comes to your family hauler, big drag. Festive drivers who festoon their crossovers, minivans, and SUVs with wreaths, Rudolph noses, fuzzy antlers, and rooftop Christmas trees undo the years of work that car engineers devote to fractional gains in fuel economy. To put numbers to such fuel-guzzling madness, GMC started with a 2018 Acadia, optioned it with the Xmas Aero Package - both Standard and Plus versions - put it in Lockheed-Martin's wind tunnel. The resulting dip in fuel economy results probably won't surprise anyone who's used a roof rack - or, for that matter, their car's air conditioning. However, it might surprise you to find out which seemingly substantial decoration had no effect, and which seemingly innocuous decoration was about twice as bad as running the A/C on its Mr. Freeze setting. Check out the brief video above for the results. And consider placement of that bow carefully.

2022 Rivian R1T vs. 2022 Ford F-150 Lightning vs. GMC Hummer EV Pickup | How they compare on paper

The 2022 Rivian R1T has arrived, ushering in the era of the production electric pickup truck. The Rivian reviews are in, and spoiler alert: They're pretty good. Curious how the new battery-powered truck stacks up to its forthcoming competitors? Well, you've come to the right place. Rivian beat all of Detroit's big automakers to market in the half-ton segment, but probably not by the margin the startup would have liked. Ford's answer is the F-150 Lightning, which is due to enter production early next year, coming hot on the heels of GM's first entry into the space – the GMC Hummer EV pickup – which is scheduled to come off the line late this fall. While all three are pickups, they're aimed at distinctly different buyers, as a perusal of their specifications will reveal. Let's have a look, shall we?   Disclaimer: Before we dive in on this one, we'd like to note that while we've made our best effort to verify the specs provided, the Rivian is brand-new and the others are still in the prototype phase. Some of these figures may be inaccurate or may simply change before production. This is all hypothetical until you can actually cross-shop them anyway, right? Cool. End disclaimer. Let's start with the powertrains. They're all battery-electric trucks engineered on a modular rear-wheel-drive configuration engineered to accommodate (theoretically, anyway) up to four electric drive units. Rivian actually makes the most use of this with a quad-motor setup producing 835 horsepower and 908 pound-feet of torque with its high-output initial model. GMC's three-motor Hummer has the R1T beat with its estimated 1,000-horsepower output, while Ford's (also three-motor) comes in with a far more modest 563 horses. This is an excellent illustration of our above point that these are not all engineered for the same crowd. Ford's F-150, which comes in at a lower price point, is meant to be far more mainstream, as its power output suggests.  This theme continues when we look at the dimensions. Despite the image "Hummer" may conjure, GMC's entry actually needs the shallowest parking space. The Rivian is right behind it, with the work-truck-spec Ford extending more than a foot longer than either. What the Hummer lacks in length, it makes up for in girth. It's the widest by a good 5 inches. The Rivian is only slightly pudgier than the F-150, but it's much closer at that end of the scale.

GM follows up Lambda CUV stop-sale with tire recall

In late January, General Motors announced a stop-sale for about 6,281 examples of the 2015 Chevrolet Traverse, GMC Acadia and Buick Enclave because of the possibility for the treads cracking on their 18-inch Goodyear Fortera HL tires. At the time, GM said that this would also eventually lead to a safety campaign to repair the problem, and the National Highway Traffic Safety Administration has just published those details. GM's recall covers 5,876 of the three Lambda platform crossovers to replace their tires. According to NHTSA, if the treads crack, there could be a loss of pressure and possible failure. Goodyear already announced its own recall of the tires after internal testing found small tread cracks. The company did not believe this was safety issue, but the problem did put the rubber out of compliance with federal laws. The business's safety campaign covered an estimated 48,512 tires. Of those, around 32,000 were reportedly made for GM to either be fitted to vehicles or sold as replacements. The remainder went to the aftermarket. Goodyear's portion of the recall is expected to begin around February 20. RECALL Subject : Tire Tread Cracking/FMVSS 110 Report Receipt Date: JAN 28, 2015 NHTSA Campaign Number: 15V044000 Component(s): TIRES Potential Number of Units Affected: 5,876 All Products Associated with this Recall Vehicle Make Model Model Year(s) BUICK ENCLAVE 2015 CHEVROLET TRAVERSE 2015 GMC ACADIA 2015 Details Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2015 Buick Enclave vehicles manufactured December 9, 2014, to January 14, 2015, 2015 Chevrolet Traverse vehicles manufactured December 9, 2014, to January 20, 2015, and 2015 GMC Acadia vehicles manufactured December 9, 2014, to January 16, 2015, and all equipped with Goodyear P255/65R18 Fortera HL tires. These vehicles are equipped with tires that may experience tread cracking. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 110, "Tire Selection and Rims and Motor Home/Recreation Vehicle Trailer Load Carrying Capacity Information for Motor Vehicles with a GVWR of 4,536 kilograms (10,000 pounds) or Less." CONSEQUENCE: If the tire treads crack, a loss of tire pressure and possible tire failure may result, increasing the risk of a crash. REMEDY: GM will notify owners, and dealers will replace the tires that were manufactured within a specific date range, free of charge.
