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.

GM extending warranties on Cadillac CTS-V and Chevy Camaro ZL1 for supercharger issue

Okay General Motors, we've sat by and watched you recall the compact cars, crossovers and pickup trucks, and aside from reporting on it, we've been fairly quiet. This, though, this will not do. We can almost tolerate the recalls on the bread-and-butter cars, but leave the performance vehicles alone.
According to a report from The Car Connection, GM has discovered a problem with the superchargers of the 6.2-liter V8s found in the Chevrolet Camaro ZL1 and the Cadillac CTS-V. Apparently, the issue rests around the internal bearing shaft grease, which can become contaminated (we aren't sure with what). If left unchecked, it'll first lead to a rattle at idle, which goes away under slight throttle. The real warning stage is when a high-pitched squeal develops, signaling that the bearing shaft has failed. Naturally, severe engine damage is the next step (although it's possible that the engine will also just refuse to turnover, although neither case is desirable).
According to TCC, GM will replace the superchargers on vehicles that have exhibited symptoms of bearing shaft failure free of charge. It will also, allegedly, be extending the warranty on all supercharged ZL1s and CTS-Vs to 10 years or 120,000 miles (whichever comes first), from the date of purchase. Officially, only 2009 to 2013 CTS-Vs and 2012 to 2013 ZL1s are suffering from this issue.

Mary Barra thinks GM is a leader in autonomous tech

Saying General Motors is "among the leaders" in autonomous vehicle technology, CEO Mary Barra rapped about her company's driverless work in an interview with USA Today. Barra covered a number of topics, including well-known efforts, like Cadillac's upcoming Super Cruise technology, as well as hinting at "a lot of efforts that are confidential." "Things are moving quickly in autonomous [cars] because there's so many different pathways and the standards aren't even set. A lot of people can claim leads because people are making advancements in different areas," Barra said. "Next year we're going to have Super Cruise on one of our Cadillacs. On highways you'll be able to take your hands off the wheel and feet off the pedals – with a very creative way to make sure the driver is alert and involved in the driving process." As for those "confidential" efforts, feel free to speculate. GM has recently confirmed that it'd be running autonomous Volts at its Warren, MI tech center, which certainly indicates that the company is playing with much more than Super Cruise. GM will need to continue to embrace autonomous driving, owing to both traditional competitors like Toyota, as well as non-traditional opposition, like Google and Apple. Speaking of its competition from Silicon Valley, Barra was asked about two of the region's biggest names – Apple's Tim Cook and Tesla boss Elon Musk. "I have tremendous respect for Tim Cook, and I don't really think he needs advice from me," Barra told USA Today with a laugh. And when asked about Apple's future as a "viable competitor," she said, "I have no insights other than what I read in the papers. But it would be foolish for me not to assume that they're going to." As for Mr. Musk's openness about future products and how it contrasts with GM's relatively closed attitude, Barra also gave a chuckle. "I'm sure you would like me to say yes. I think we're fundamentally different. Look at our volume and look at the segments where we compete. His product line – his two products – his scale, it's completely different." The rest of Barra's interview is certainly worth a read, and includes talk about the Volkswagen diesel scandal, GM's changed relationship with the National Highway Traffic Safety Administration, and Uber.
