Cadillac Celestiq, Lyriq, Hummer, other future GM electric cars: Here's everything we saw at ‘EV Day’

WARREN, Mich. — Today, General Motors held an “EV Day” event at its Warren, Michigan, campus to present its new “Ultium” battery technology, modular electric vehicle architecture and soon-to-come electric vehicles. Unfortunately, we were forbidden from bringing cameras into the event, so while we canÂ’t show you what we saw, we can tell you more about it. While we saw the previously teased Cadillac EV (which we now know to be called the Lyriq) and the GMC Hummer pickup teased during the Super Bowl, there were a number of other future cars at the event, which GM President Mark Reuss assured us are all real vehicles in the works. The biggest surprise came at the end of the event, though, in the Cadillac Celestiq electric sedan, which Reuss described as a future flagship that would be hand-built “very locally.” It had been hiding under a dark sheet all morning, with the front and rear illuminated Cadillac emblems shining from underneath. When the wraps came off, we saw a long, white, four-seat fastback sedan. The 23-inch wheels were pushed out to the very corners of the car, giving it what appeared to be a very long wheelbase. The model on the stage had no side mirrors or visible door handles. The grille mirrored that of the Lyriq crossover next to it, with integrated lighting in lieu of the usual mesh or slats youÂ’d see in an internal combustion car. The entire roof, all the way until it tapered to the tail of the vehicle, was tinted glass. In back, vertical tail lighting ran down the C-pillar before turning rearward across the top of the trunk. Inside, everything below the beltline of the windows — essentially all but the headrests and top portion of the steering wheel, was hidden from view. Behind the Celestiq, a large digital display showed a rendering of its interior. The dash consists of a pillar-to-pillar curved LED display serving as both instrument panel and infotainment system. Protruding forward between the front seats was another touchscreen that appeared to house some more controls, with open area, probably for storage, below it. The rear seats had the same sort of touchscreen between them. Built into the back of the front seats were a pair of rear-seat entertainment screens, much like we saw in the Lyriq. The door panels blended wood, metal and animated lighting to give character and a sense of opulence. GM interior design manager Tristan Murphy was on hand to tell us a bit more about the Celestiq.

Meet Alex Archer, the engineer behind GM's power-sliding center console

In 2009, a GM manager complained to a 59-year-old GM technician about the hassle of retrieving items from a pickup truck bed after driving shifted the cargo. In two days, the tech had come up with the ideas that, ten years later, would debut as the MultiPro tailgate. The engineering teams kept the tailgate secret in part by hiding mock-ups in a locked storage closet in GM's Vehicle Engineering Center in Warren Michigan for two years. A piece in the Detroit Free Press reveals that another storage closet in Warren would play the same role in a different cloak-and-dagger operation, this time for the power-sliding center console in GM's new full-sized SUVs. During a meeting in early 2017, bosses gave the job of the console's creation to 24-year-old design release engineer Alex Archer, just two years out of Stanford University with a degree in engineering and product design.  This time, the catalyst for the feature was an internal GM think tank called co:lab, where employees suggest ideas. Execs gave Archer the task because "They needed someone willing to ask a lot of questions," her 36-month mandate to produce a six-way console that could be a standard cubby or a gaping maw able to swallow four gallon jugs or hide a secret compartment. Clearly, she succeeded. It took Archer and the team nine months to devise a prototype, another six months to get the green light for production. As with the tailgate, the team working on the console grew to include designers, production engineers, and suppliers. Archer, now 26, shepherded the process, and her name is on the patent. "It took a ton of people, I'm just somebody who stuck with it the whole time," she said. GM like her work well enough to produce the "Day in the Life" segment above, five months before the world would hear about the console. Archer's path to engineering was as unlikely as getting the job for the console. She had entered Stanford with plans to be a doctor. But an innovation class during her freshman year, and a sophomore summer spent helping her grandfather rebuild a 1937 MG engine recharted her course. Her grandfather told her, "You know, you could be an engineer for a car company." Consumer reaction to Archer's work won't be far off, the SUVs slated to hit dealerships soon. Meanwhile, she's busy on something that could be just as intense as the console: Restoring a 1955 Packard Clipper in her garage. Head to Freep to check out the story of Archer and the console.

2018 GMC Sierra 2500HD All Mountain concept: Nothing stops it in its tracks

Winter may not be the best time for sports cars, but snow and ice can still provide a ton of fun in the right vehicle. The Porsche Macan GTS I had back in January was a riot in the snow, and it was wearing nothing more than a good set of winter tires. What you really need to conquer the frozen north is tracks. These replace wheels with the same sort of equipment that helps tanks and snowmobiles roll over damn near everything in their paths. That's what makes the 2018 GMC Sierra 2500HD All Mountain concept so awesome. That and the 910 pound-feet of torque from the 6.6-liter Duramax turbo diesel V8. The All Mountain concept is set to debut this week in Veil, Colorado, home to ski slopes, log cabins and nearly year-round snow pack. The truck is based off a standard GMC Sierra 2500HD. The turbo-diesel V8 makes 445 horsepower in addition to the mountain of torque. Power is sent to all four corners through an Allison 1000 six-speed automatic. The new treads come courtesy of Mattracks. The 150 Series tracks aren't cheap — well into five figures with installation — but they give you a nice 16-inch surface at each corner. Other changes and add-ons include graphics on the bodywork, a RIGID E-Series 30-inch light bar, LEDs on the wheel well and underbody, Thule snowboard racks, a roll-up tonneau cover and a new speaker system from Kicker. The truck will stay on display in Veil all winter, though a similar concept will be making its way to various auto shows, starting with Los Angeles next week.
