Cadillac Celestiq previewed as a flagship luxury electric car

Last year, our Autoblog Green editor, John Beltz Snyder, got a sneak peik of GM's upcoming electric car roll out. No photos were given, but he described them in great detail. Now we finally get our own peek at one of those cars, the Cadillac Celestiq flagship sedan. Sadly, we don't get a particularly clear look, since Cadillac is only teasing the car at this point, but it's better than nothing, and better than most teasers. We get a top-down shot that reveals the car will share some key cues with the Lyriq crossover EV. Most obvious is the rear with the boomerang taillights and fastback roof, which is a glass unit separated into four pieces. Each piece can be individually adjusted for transparency, and it appears they can be illuminated as well. The front also appears similar to the Lyriq with a geometric grille covered in a transparent panel. The grille looks significantly larger, though. It also features illumination like the crossover. We also get a look at the interior, which prominently features a full-width screen for instruments and infotainment. There appears to be a screen in the center console/stack that can control functions including the roof panel illumination. According to Snyder, the interior also has extensive wood and metal trim intermingling with nifty ambient lighting. Cadillac didn't say much about the mechanical aspects except the basics. It will use GM's Ultium battery technology that will be shared with other products such as the aforementioned Lyriq and the GMC Hummer EV. It will also feature four-wheel steering as well as all-wheel-drive, undoubtedly courtesy of dual motors, one front and one rear. Cadillac previously confirmed that the Celestiq is headed for production. We also suspect that some of the fancy features such as the screens and multi-panel glass roof could make it to production. This is because it's meant to be a halo product showing off the ultimate in luxury and technology from the brand, and it could have a price tag larger than $200,000. We're expecting Cadillac to fully reveal the Celestiq in a few months, but it could be a while before the production version hits the road. The Lyriq isn't going on sale until late next year, and we would bet the Celestiq wouldn't come ahead of it. Related Video:

Super Cruise’s failsafes

Even though Super Cruise is not a fully autonomous system, it incorporates redundancies like those used in aircraft to ensure failsafe operation. Before taking off on a 700-mile, 11-hour test drive of the system — and putting my life in its hands without my hands on the wheel — I sat down with Daryl Wilson, lead development engineer for Super Cruise, to get a deep dive into the system and its critical safety backups. Autoblog: First, what makes Super Cruise different from similar systems? Wilson: The key differentiator for Super Cruise is hand-free driving. It's an industry first in that respect. Our competitors require the driver at minimum to place their hands on the wheel with some frequency to ensure that the car knows that the driver is there. We don't. Two key technologies allow us to do this. One is our Driver Attention System, which is our methodology for making sure the driver is engaged with the vehicle and engaged with the road. This is a driver assist system, not a fully autonomous system. So it requires driver engagement. We use an infrared camera that constantly monitors the driver's face to determine the direction they're looking. We're looking for the driver to be what we call on-road — not on the center stack, not to left or right or down. That's all done by the tracking of the face. We also track that the eyes are open. It's infrared because at night you need to illuminate the face and you can't be shining a light into the driver's face. Then we have our lidar mapping that provides a foundation for control and redundancy to ensure safe performance. Autoblog: How does the mapping act as a redundant feature? Wilson: This system is only for use on divided, controlled access highways. What I mean by a divided highway is something more than a painted line between you and oncoming traffic. Whether that's a grassy area in between the lanes or a concrete barrier, anything that separates you from oncoming traffic. That's the divided highway part. The controlled access part is entrance ramps and exit ramps. Not with roads that cross at grade, with traffic crossing at the same level. To do that we geofenced these roads to ensure that operation is only allowed in these conditions. We don't just recommend you use it there; we ensure that you only use it there.

2015 Cadillac ATS Coupe First Drive

Save for a few years of its century-plus existence, Cadillac has offered its unique brand of American elegance in two-door, fixed-roof bodystyles. Most of these cars were big, floaty barges, of course, though its most recent offering was the wedge-shaped CTS Coupe. But whereas the CTS Coupe was a statement car – angular and severe, with somewhat limited appeal except to design snobs and provocateurs – the ATS Coupe represents a return to form for Cadillac, with a proper three-box (engine-cabin-trunk) body and a slightly lower price point that should broaden its appeal among a larger swath of the market. Generally speaking, the 2015 ATS Coupe is a two-door version of the sporty ATS Sedan, though, surprisingly, the only common exterior components are the hood, headlamps, and sundry trim pieces on the front fascia (which features a slightly larger grille, a wider lower air intake, and the redesigned, laurel-less Cadillac crest). Even the mirrors are different. The body stretches 0.8 inches in length and 1.4 inches in width, the roof is 1.1 inches lower and the rear windscreen slopes at a flatter, sleeker angle. Interestingly, the windowsills are actually quite a bit lower, further slimming the car. Thanks to its 0.8-inch wider front and rear wheel tracks as well as more tumblehome in the C-pillar area, the coupe sits lower and looks more planted than the ATS sedan, particularly from the rear three-quarter view. Filling the wheel wells is a family of slick 18x8-inch wheels, with 18x9-inchers coming on the rear axle of performance models. Even if all those changes haven't resulted in a wholly new look the way the CTS Coupe departs from its sedan progeny, the ATS two-door is a truly beautiful car that looks considerably better on the road than on a show stand. And for that, Cadillac deserves mighty praise. The ATS two-door is a truly beautiful car that looks considerably better on the road than on a show stand. It is a proper coupe, of course, and as such is saddled with the expected limitations that accompany modern two-door packaging, notably rear seat access and limited rear headroom. Since the floorpan is common to both bodystyles, rear legroom is the same as the sedan's, though headroom shrinks a considerable 1.8 inches, making it hard for even average-sized adults to sit back there without their heads touching the window glass.
