2019 GMC Sierra Denali and its nifty tailgate roll into dealers

We've got more details about the 2019 GMC Sierra Denali now that it's rolling into dealerships, starting with its floor price of $56,195, including destination fee, for the rear-wheel-drive models. That's a jump of $1,900 over the previous generation of its premium full-size pickup. Four-wheel-drive models start at $60,295. The crew-cab truck has grown in every dimension as well, adding about 4 inches to the wheelbase, nearly 2 inches in length and 1.2 inches in width. There's also nearly 3 inches more rear legroom. Bed options are 5-foot-8 or 6-foot-6. There are three engine options. Two are carryovers from 2018: a 5.3-liter V8 that sends 355 horsepower and 383 pound-feet of torque through an eight-speed automatic transmission, and an available 6.2-liter V8 that makes 420 hp and 460 lb-ft of torque and mated to a 10-speed automatic. Both come with GM's dynamic fuel management cylinder-deactivation technology to optimize power and fuel efficiency. A new 3.0-liter turbodiesel paired with a 10-speed automatic is expected in early 2019. The EPA hasn't yet released official fuel economy ratings, but GM estimates them at 17 miles per gallon in the city and 23 mpg on the highway for the two-wheel-drive versions, and 15/21 in four-wheel drive. The truck gets adaptive ride control which can adjust the dampers every 2 milliseconds based on real-time monitoring of the road and driver inputs for improved ride and handling. A new traction select system adjusts the transmission shift points, throttle mapping and StabiliTrak to tailor performance to different terrain or weather conditions. Inside the crew cab, there's new Forge leather-appointed seats, open-pore wood trim and dark finished aluminum decor, plus an 8-inch-diagonal HD color touchscreen with embedded navigation and Apple CarPlay and Android Auto compatibility. Most of the other new stuff we've covered before, including new C-shaped LED headlights and LED tail and fog lamps, optional 22-inch wheels, full-color head-up display, trailer-hitch assist apps and cameras, and rear-camera mirror. The truck also loses up to 360 pounds from the outgoing model via a scratch- and dent-resistant carbon-fiber bed box that replaces steel, and use of aluminum in the doors, hood and tailgate.

GMC Hummer EV's taillights cost thousands to replace

The GMC Hummer EV pickup hasn’t stopped raising eyebrows since GM pulled back the curtain on the behemoth in Spring 2021. ItÂ’s huge, not all that efficient, and unbelievably expensive, but now weÂ’re learning how much replacement parts cost for the new EV. The Drive dug up a post from the Hummer EV Facebook page that claimed a taillight replacement for the vehicle costs thousands to replace. General Motors confirmed pricing to the publication, quoting a one-side replacement cost of $3,045.48. That adds up to more than $6,000 to replace both, so we hope your insurance is solid if you own one. Why would a taillight housing cost that much? Part of the cost comes from the fact that GM couldnÂ’t parts-share its way through the design of a $100,000 flagship electric SUV, but most of the price comes from the complexity of the lights. The Hummer offers elaborate lighting sequences that require microchips and other components, all of which cost money. ThereÂ’s also the fact that the Hummer EV is too new for General Motors to take advantage of its usual economies of scale in mass-produced vehicles. General Motors recalled the Hummer EV earlier this year for issues with the taillights. Though the problem was software-related, GM had to replace the entire light units because the software controlling them was actually embedded in the lights. ItÂ’s true that there are very few vehicles that are tall and large enough to impact the HummerÂ’s taillights, but we hope the owners of those vehicles never have to file an insurance claim to replace one.

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.
