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.

GM looks to combat high theft rates on SUVs with added tech

The Cadillac Escalade has been at or near the top of most-stolen and insurance-loss lists for more than seven years, until it dropped to number six earlier this year. In 2011 it was fitted with a host of new security features to address its easy-to-override features and that has brought the number of thefts down, but when eight of the ten most stolen rides are large SUVs from General Motors, no one will argue that something else needs to be done.
Thus, GM has fitted this same theft-deterring tech to the 2015 Suburban, Tahoe and Yukon. The Suburban and Tahoe will get the steering lock that the Escalade and Yukon already get, plus bolted-down third-row seats to deter thefts like this, stronger door lock cylinders and shields, and side-cut keys to inhibit picking.
Additional security measures in a Theft Protection Package can be purchased for $395, consisting of sensors on the greenhouse glass and interior, an incline/tilt sensor and added "key control systems" to make it more difficult for the men in black balaclavas to steal what you bought.

2020 Chevrolet Tahoe, Suburban and GMC Yukon all spied with production lights

One of our spy photographers just caught a smattering of full-size GM SUVs out testing, including the Chevrolet Tahoe, Suburban and GMC Yukon. Previous spy photos of the next-generation of these big GM SUVs have revealed that GM is going with an independent rear suspension design, and these shots confirm the news once again with our best look at the hardware yet. Check them out from the rear, lined up like ducks in a row to see the beefy control arms down there. This will undoubtedly give the big SUVs a more compliant ride, and should bring it back into touch with the refinement from the Ford Expedition and Lincoln Navigator. The new bits we get to see with these shots are production headlights and taillights that are shaping up to look pretty neat. Most distinguishable are the GMC Yukon's LED DRLs. These look a lot like the C-shaped LEDs outlining the headlights on the Sierra, but they have an extra LED strip on top of the C. The parts of the taillights that we can see look significantly different than that found on the Sierra, showing GM is planning on having a great deal of differentiation there. We can sort of see through the mesh covering the grille to what appears to be a classic horizontal bar style front opening. Chevy is predictably dialing the crazy LED strip design back for the Tahoe and Suburban. The parts that are lit up look a whole lot like the headlight fixtures on the 2019 Silverado. That truck uses a stack of lights with the actual headlights separated from the DRLs. We can see the same thing going on here, with the headlight up top and curved LED DRL strip sitting below. It's tough to say if the designs are exactly alike, but we expect to see an extremely Silverado-esque look once all the camouflage comes off. Chevrolet's taillight design differs from its donor truck like the GMC, showing off a curved, vertical series of LEDs out back. Once production lights start popping up like this, we know the vehicle is moving closer to its end game. A reveal sometime later this year could be in the cards for GM's next batch of full-size SUVs. It certainly needs them quick, as Ford rockets ahead with increased Expedition production announced earlier this week.
