2016 Cadillac CT6 to get an aluminum body?

Well this is interesting: A hot-off-the-press report in Automobile claims the coming Cadillac CT6 will have an aluminum body. Most write-ups on the CT6 claim it will have a body that's a combination of aluminum and high-strength steel - Automobile itself wrote of "high-strength steel, aluminum, and steel stampings" in October. An all-aluminum body would be quite the reversal, contradicting the last four months of reportage and company statements on the matter. Mark Reuss, EVP of global development at General Motors, told The Detroit News in October, "We will create with the CT6, the world's most advanced body structure... [and] it's not aluminum. It's a stronger, smarter, safer premium luxury vehicle." It echoed the earlier Automobile story in saying the CT6 would use GM's "patented welding technology with high-strength steel, aluminum and steel stampings and castings." That same month, the Wall Street Journal ran a piece titled, "GM Won't Follow Aluminum Strategy in Future Cars," in which Reuss said, "making big statements around all carbon fiber, all aluminum, all magnesium, they're very interesting," and that GM wouldn't be doing it. That piece also circled back to a material mix and GM's special welding process, saying the CT6 "will have a body made of aluminum, high-strength steel and other materials, and will be 100 kilograms (220 pounds) lighter than a similar-sized car made of high-strength steel." We don't know what kind of body Cadillac's new assault on luxury is going to wear, but now we can't wait to find out.

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.

2021 Cadillac Escalade will get next-gen Super Cruise with auto lane-change

Super Cruise is getting its first big update since it was originally launched on the 2018 CT6 sedan. As that large car fades away, this new version of Super Cruise will be coming online in the 2021 CT5, CT4 and … the 2021 Escalade! Yes, ladies and gents, Cadillac is finally applying its advanced driver assistant to the iconic Escalade. The biggest change to this version of Super Cruise is a new feature called “Lane Change on Demand.” When Super Cruise is engaged, the driver can tap the turn stalk, and the car will execute a hands-free lane change if itÂ’s safe to do so. This kind of lane-change functionality is similar to that offered by other manufacturers' systems (i.e. Mercedes-Benz, Tesla, BMW). However, like the rest of Super Cruise, the car is able to complete the task with the driverÂ’s hands completely off the steering wheel so long as the driver monitor can tell that youÂ’re paying attention. Further improvements abound. “This is our most extensive update weÂ’ve made to Super Cruise since its debut,” said Mario Maiorana, Super Cruise chief engineer. “We have made a number of improvements to make Super Cruise more intuitive, better performing and more accessible for our customers. In addition to the automated lane change functionality, weÂ’ve made improvements to the user interface and hands-free driving dynamics.” Cadillac says that it has gathered richer map information to make the lane change function possible and also to make turns and highway interchanges smoother. The software was also improved with the aim of gaining “better steering and speed control.” Cadillac also made the system easier to engage. It did this by allowing the operator to switch the Super Cruise system on, and then get the vehicle in a proper lane position — it automatically activates once the vehicle is positioned. Previously, the driver had to get the vehicle centered in the lane properly, and then you were allowed to switch the system on. The auto lane changing function operates similarly to other systems like it. When driving, you can either tap or fully depress the turn signal stalk. The car then looks for an acceptable opening in the indicated lane. Once found, the car begins its lane change. Within the gauge cluster, there are animations that keep the driver apprised of the lane change at all times. Once the vehicle has moved into the new lane, itÂ’ll shut the turn signal off and continue driving along.
