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.

400,000 Chevy, GMC pickups recalled: Side airbags can explode

DETROIT — General Motors is recalling more than 400,000 pickup trucks in the U.S. because the side airbags can explode without warning and spew parts into the cabin. The recall covers certain 2015 and 2016 Chevrolet Silverado and GMC Sierra 1500, 2500, and 3500 trucks. Documents posted Friday by U.S. safety regulators say the airbag inflator can rupture or the end cap can fly off on both sides of the trucks. Documents say three inflators ruptured in 2015 Silverados last month, one in Florida and two in Texas. All three trucks were unoccupied at the time, and GM says it has no reports of injuries. Dealers will replace both side airbag modules. The company says it has a limited number of replacement parts available. Owners will be notified starting Aug. 16 and they'll get a second letter when parts are widely available. About 9,000 of the trucks were recalled last year for the same problem. The company says a manufacturing defect allowed moisture into the inflator while it was being manufactured, causing corrosion. The inflators were made in Mexico by Joyson Safety Systems, the company that took over Takata. Back in April, Silverado and Sierra were among nearly 750,000 GM vehicles in a National Highway Traffic Safety Administration (NHTSA) investigation into non-deploying driver-side airbags. That investigation is ongoing. Takata is responsible for the largest recalls in automotive history, covering about 100 million inflators among 19 major automakers worldwide, including about 67 million inflators in the United States. Nineteen deaths in the U.S. have been attributed to Takata inflators. Only about 50 million of the 67 million recalled inflators in the U.S. have been repaired. This latest recall is a good reminder to go to NHTSA's recalls website and enter your car's VIN. Millions of recalled vehicles still pose a danger to their owners. Yours could be one of them.   Recalls Chevrolet GM GMC airbag Takata airbag recall

GMC Canyon Denali Interior Review: THE luxury midsize truck

Over the past couple of years, GMC has been getting serious about being more than just a rebrand of Chevy trucks and SUVs. The same goes for the luxury Denali line. Among the beneficiaries of this push for differentiation is the latest Canyon. On top of only being available with the wide-track layout and the most powerful engines, it gets a Denali trim that is unequivocally the most luxurious midsize truck in the segment. The GMC Canyon Denali could even be described as a luxury midsize truck, of which there are no others. And it all comes down to what GMC has done with the interior. Open the door, and the upgrades are immediately obvious. There's leather everywhere. It's on the dash, the door panels, center console and doors. And it has nice details with the perforation and quilted stitching. The seatbacks get embroidered Denali logos and contrasting leather panels, too. The feel is more rugged than supple, but it is a truck after all, and the materials feel like they'll wear nicely.  Then you notice the wood trim. The real wood trim. It's subtle, just adorning a strip along the top of the dash and the front door panels, but the light brown color stands out against the black leather and plastic elsewhere. It's got a natural, open-pore finish that highlights the material, and the strip in the dash gets extra laser-cut details. The branding consisting of DENALI, some stylish strakes and the coordinates of Denali, the mountain, are crisp and clear. Throw in plenty of shiny chrome, and the same quality-feeling buttons and knobs (the knurling details on the knobs are particularly nice), and just on trimmings alone, it's obvious the Denali is the most plush little truck. The seats themselves are solid, though not particularly exceptional. The front seats are a bit flat, but they're also very roomy. On the Denali, the driver's seat has eight-way power adjustability with memory, and the passenger has six-way power adjustability. Heating and ventilation are included, too. Leg, head and shoulder room are also all excellent up front. The rear seat, like the rest of the segment, has enough room for adults, though legroom is a tad tight, with knees likely brushing the front seat backs. The seat bases in the rear are split with storage underneath, although it's not particularly useful. Besides its meager volume and awkward shape, much of it is taken up with the jack.
