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.

2023 GM full-size SUVs get Super Cruise expansion pack first

In August, GM announced it had doubled the size of the network of roads available to its Super Cruise hands-free driving feature. Joining the options list in 2017, Super Cruise had been limited to divided interstate highways in the U.S. and Canada. The expansion opened 200,000 miles of additional divided interstate highway as well as major, undivided highways. Both coasts benefit, but there will be a lot more relaxing motoring on the East Coast especially. North of the border, six of the 10 Canadian provinces add enabled roads. Problem is, no GM vehicles have been able to take advantage of the boon. That changes this month, the automaker saying four of its full-size SUVs in specific trims are first in line to make use of the expansion. The SUVs are: 2023 Chevrolet Tahoe Premier and High Country 2023 Chevrolet Suburban Premier and High Country 2023 Cadillac Escalade, Escalade ESV, and Escalade-V 2023 GMC Yukon Denali Ultimate  The vehicles need to have been built on or after October 3, 2022, a production timeline GM says should put the first examples in customer hands this month. The least expensive way to get into Super Cruise is with the two-wheel drive, $77,625 Chevrolet Tahoe Premier with the 3.0-liter inline-six Duramax diesel and the Advanced Technology Package. Vehicles that use the GM's Vehicle Intelligence Platform electrical architecture and already have Super Cruise will receive an over-the-air update "in the coming months" to access the new roads, at no cost to owners. Since other products like the Cadillac CT4 and CT5, Chevrolet Silverado, and GMC Sierra work with the VIP platform as well, they probably aren't far away from the extra capability and they'll bring a lower financial bar to entry.  Related video:

2022 GMC Sierra 1500 Denali interior spied with dramatic redesign

The 2022 GMC Sierra’s interior overhaul is coming into better view with these new spy shots revealing a totally new dash.  GMC teased out a few changes when it announced Super Cruise was coming to the 2022 Sierra, but only so much was visible in the tightly cropped photo. These spy shots tell a fuller story about whatÂ’s going on inside the new GMC pickup. WeÂ’re instantly drawn to the new center stack that doesnÂ’t even remotely look like the truckÂ’s current design. ThereÂ’s a new widescreen infotainment system integrated nicely into the dash just below new thin air vents. It appears to be running a version of Android Automotive. The Google Assistant bubble is visible in the top left corner, and a Google sign-in screen is showing on the far right. GMC is obviously still prioritizing hard buttons and knobs for all vital controls. A big, knurled-looking volume knob is positioned to the left of the screen. And the climate control layout is all buttons and knobs with glossy black and chrome accents. This, along with the angled surfaces, classes it up a bit versus the current sea of flat black center stack buttons. Even the push button start appears dressed up in chrome. One other large change to the center console area is the introduction of a gear lever replacing the column-mounted shifter. The new shifter looks slathered in leather, glossy plastic and chrome accents. ThereÂ’s a part of us that will miss the chunky truck-like operation of the column-mounted shifter, but this new design is certainly more befitting of a luxury pickup. And from what we can tell, this Sierra is the luxury-oriented Denali trim. Its exterior features give it away with the ostentatious grille treatment and chrome trim scattered about. We still donÂ’t know which, if any, of these features we see here will be exclusive to the Denali, but the digital instrument cluster seems like a given but will likely be available further down the trim tree. This replaces the truckÂ’s current, tired-looking gauges with a vibrant and neatly-integrated screen. Super Cruise, as it is throughout the lineup of GM cars that offer it, also looks optional — this Denali does not have the fancy light-up steering wheel or controls for it. ItÂ’s worth noting that this DenaliÂ’s interior could be different than the rest of the Sierra lineup. GM already did that with the redesigned Yukon, giving its top trim model a different look than the rest of the trims.
