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.

REWIND: Watch the GMC Hummer EV live reveal right here

It has been a long wait to see the GMC Hummer electric pickup truck, which was teased way back at the Super Bowl in February of this year. And that wait ends tonight at 8 p.m. eastern time when GM pulls the covers off the truck. You can see the whole reveal right here, or during the World Series on Fox or "The Voice" on NBC. For everything we know about the truck, go to our reveal post here. The truck should be impressive. GMC has previously announced it will have up to 1,000 horsepower, and it will have a variety of fun features such as removable roof panels and four-wheel steering that can move the truck sort of sideways with "Crab Mode." The GMC Hummer will also be available in pickup and SUV forms. So be sure to tune in tonight for one of the biggest (figuratively and literally) vehicle reveals of the year. And keep an eye on Autoblog for all the latest on the Hummer and other vehicles.

Mystery man buys fast food worker a new car

A mystery man bought a Tennessee fast food worker a new car. 34-year-old Jeff Smith told WKRN he was approached by an older stranger as he was exiting a grocery store. The two struck up a conversation about Smith's 1991 Geo Storm. The vehicle is falling apart; it has more than 350,000 miles on it, a cracked dashboard, no drivers side window, and a door that is literally being held closed by a small hook. The stranger asked Smith to follow him down the road to James Motors, but then asked the fast food worker to wait outside. Smith told WKRN, "He comes back out and says, 'How do you like that blue pickup?' I said. 'It looks great.' Then he said, 'Well, I bought it and it's yours now.' [...] It's just a blessing. It's the best thing that has ever happened to me." At first, Smith didn't believe this was even real. But the owner of James Motors showed up at the fast food restaurant where he works with the keys and title to the 2001 navy blue GMC Sonoma. The mysterious benefactor didn't want to be identified, but asked smith to do something nice for someone else in the future. Weird Car News GMC geo
