Super Cruise will make 2018 Cadillac CT6 semi-autonomous

General Motors has been working on its semi-autonomous driving system for years. Called Super Cruise, it had initially been slated for a fall 2016 debut. Of course, something as critical to safety as a self-driving system should ideally have the bugs worked out before putting it in the hands of customers, and the launch date had to be pushed back. It appears that Super Cruise is road-ready now, as Cadillac has announced the system will be available in the 2018 CT6 sedan when it goes on sale this fall. Super Cruise offers hands-free driving on the highway, taking control of steering and speed under the supervision of the driver. An attention detection system – a camera and infrared lights that track head position – ensures that the driver is paying attention and is available to take over driving responsibilities. If needed, Super Cruise will initiate a series of nags, including a flashing light bar on the steering wheel, to regain the driver's attention. If the driver is unresponsive, the system can bring the car to a safe stop and use OnStar to call first responders. The system employs a suite of sensors, cameras, and GPS, as well as precision lidar-scanned map database, to place the car where it needs to be on the road and in the center of its lane. It only works if the sensors detect appropriate road conditions, and is limited to the more predictable terrain of divided highways with on- and off-ramps. Yes, it's limited, but safety is paramount, and drivers who spend a lot of time on the highway will appreciate the convenience nonetheless. Related Video:

GM will likely build PHEV batteries in China soon

It's a big week for batteries. Friday, Tesla will hold a big event at its Gigafactory in Reno, NV. But even in Michigan, there are things happening on the electrified automotive front. This was proven when GM invited journalists to its Brownstown Battery Assembly Plant today, highlighting the six different battery packs it makes for nine vehicles around the world (plus a tenth, coming to Asia, that has not yet been announced). During our tour, we learned a few interesting tidbits that we thought readers would like to hear: The Cadillac CT6 plug-in hybrid launches in China this fall before coming to the US next year. GM builds the battery packs in Michigan and ships them to China for final assembly in the PHEV. For now, this is all fine for GM to qualify for China's incentives for building green cars in the country. But, as Bill Wallace, GM's director of global battery systems, told AutoblogGreen, this could change thanks to the country's 'Made in China 2025' plan. The situation is "evolving," he said, and it's a safe assumption that GM will need to build packs in China some day. For the CT6 PHEVs that will be sold in the US, the batteries will make a round trip, since GM will only build the plug-in version in China. As for the range of the CT6 PHEV, that hasn't been announced, but since China offers incentives for vehicles that get at least 50 kilometers (31 miles), that's a likely target (the US range (UPDATE: GM did announce an expected range for the CT6 PHEV in the US at the LA Auto Show last fall, saying it would "travel approximately 30 miles on a full electric charge"). The battery pack in the CT6 is also a clunky box-type thing, totally unlike the near-elegant T-shape used in the Volt. This despite the fact that the guts of the two packs are similar. Both have 192 li-ion cells and weigh almost the same, but GM tuned the CT6 pack for acceleration instead of range, the way it did with the Volt's pack. Still, the main reason the packs are different is because the CT6 is a rear-wheel drive vehicle, and the tunnel that the Volt's pack uses is occupied by the driveshaft. Despite the highly touted second-gen Chevy Volt going on sale last year, GM still has the capacity to build battery packs for the old, first-gen model. This is because the company is legally required to be able to provide replacement packs for warrantied vehicles (for up to 10 years), and the second-gen packs don't fit into the first-gen vehicles.

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:
