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.

2024 GMC Sierra HD unveiled with new design and more powerful turbodiesel V8

The 2024 Chevrolet Silverado HD made its debut in September 2022, so it was only a matter of time before the GMC Sierra HD received a similar round of updates. Unveiled online, the truck gains a new-look design and a more powerful turbodiesel V8, among other changes. GMC developed the Sierra HD primarily for towing and hauling so the most significant changes are found under the hood. The available 6.6-liter turbodiesel Duramax V8 engine now develops 470 horsepower at 2,800 rpm and 975 pound-feet of torque at 1,600 rpm, figures that represent increases of 25 and 65, respectively, over the 2023 model and that match the 2024 Silverado HD's. GMC notes it increased low-end torque by about 25% by fitting a new turbocharger. The V8 spins the rear or the four wheels via a 10-speed automatic transmission.  On the gasoline side of the spectrum, the 6.6-liter V8's output stays flat at 401 horsepower and 464 pound-feet of torque. It's now bolted to a 10-speed automatic transmission, and replacing the 2023 truck's six-speed lets the engine run closer to its peak power for longer periods. Here again, rear-wheel-drive comes standard and a part-time four-wheel-drive system is available across the entire line-up. Properly equipped, the 2024 Sierra 2500 HD Crew Cab can tow up to 21,900 pounds. The standard 2500 HD's towing capacity checks in at 22,500 pounds (a 4,000-pound improvement), and the 3500 HD is capable of towing up to 36,000 pounds — that's nearly 13 Subaru BRZs. Buyers have a dizzying selection of trim levels and body styles to choose from. The range includes Regular, Extended, and Crew cabs as well as seven trim levels called Pro, SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate, respectively. The AT4X variant will not be available at launch, and the Denali Ultimate is new for the 2024 model year. Additionally, 3500 HD models can be ordered with dual rear wheels. What the truck looks like depends on the trim level. Broadly speaking, designers drew a more angular front end with a new-look grille, sharper-looking lights, and a redesigned bumper. New wheels are part of the update as well; the 3500 HD dually gets 18-inch polished aluminum wheels, and 22-inch units are optional on single-rear-wheel trucks. Finally, the color palette grows with six optional shades called Titanium Rush Metallic, Sterling Metallic, Volcanic Red Tintcoat, Redwood Metallic, Meteorite Metallic, and Downpour Metallic, respectively.

GM releases full Super Bowl ad with GMC Hummer, Cadillac Lyriq: Take that, Norway!

GM just dropped its big Super Bowl ad, and it’s a good one. Will Ferrell, Kenan Thompson and Awkwafina all star in the 90-second ad titled “No Way, Norway.” The point of the ad is to get Americans hyped up about the upcoming electric vehicle range on its way from GM. Both the Cadillac Lyriq and GMC Hummer EV star throughout, but itÂ’s less about the vehicles, and more about changing attitudes about EVs in general. Ferrell comes after Norway aggressively, but in a playful and competitive way about how many electric cars sell in the Scandinavian country. Over half of all new car sales in Norway are of EVs, whereas GMÂ’s data show that just 4% of new cars sold in the U.S. are electric. Massive financial incentives from the Norwegian government can take much of the credit for why EVs sell at such high rates over there. However, GM thinks it can still rally the U.S. to get more excited about buying EVs once its fleet of cars using the companyÂ’s Ultium battery tech comes online. The ad is done with classic Ferrell comedy, and it sure did elicit some chuckles from us. It also follows the same “Everybody In” philosophy that GM announced back when it changed up the logo a short time ago. GM is inviting folks to strap in for the onslaught of EVs coming their way (for now, you can buy a Bolt). President BidenÂ’s administration has voiced support for a number of policies and actions to take for greater adoption of electric cars in the U.S. — we also know the federal government intends to transition its full fleet of vehicles to EVs. It's still unlikely that we make it to Norway's rate of electric car sales in the immediate future, but the U.S. could certainly begin to close the gap. Related video:
