Cadillac CT6 to get twin-turbo V8

Say what you will about his decisions at Infiniti and now Cadillac, but Cadillac CEO Johan de Nysschen knows how to deliver a compelling interview. During an online Q&A session with Jalopnik readers, de Nysschen offered substantial hints at what's coming for the brand. By dropping coordinates on the brand's star chart, in reading the entire thing and connecting the dots you can see a Cadillac that is much grander than the one we know now. The CT6 that got revealed during the Oscars telecast? Answering the question of whether it would have the performance to compete with a Mercedes S550 or BMW 750, de Nysschen said the big sedan's "lightweight body structure allows us to achieve formidable performance even with a twin-turbo V6. Imagine how this car would perform with a twin-turbo V8." In clarifying a subsequent question that also dealt with how the CT6 would compare to German rivals, he wrote that the CT6 would have "a very wide mix of engines, starting with a two-liter turbo, up to, eventually, a high-performance advanced V8 turbo." Patience and the future and the word "eventually" were heavy themes. The brand will embrace diesel engines as well, de Nysschen writing, "We will have four-cylinder and six-cylinder diesel engines, but not before 2019." As to the return of something like the XLR, which was Corvette muscle underneath a Cadillac body, he wrote, "I think in the fullness of time, we will get around to developing a high-performance, very-emotive sports car as a halo for the Cadillac brand. But we have so many projects to occupy us through 2020 that this will have to wait a little while." And on the design language across model lines, which enthusiast Cassandras have warned is too similar (as if that hasn't worked out for the Germans), he wrote that it is "undergoing gradual evolution and you will notice stunning new designs in future models, which remain unmistakably Cadillac and reflect our DNA but which take our sophisticated Art and Science design to a new level." But of course he would say that, which is what brings us back to patience and the future and eventually, when we'll see what this all really means. It all reads well enough, and we'd love to see it happen. One thing we won't see are the ducks that once adorned the Cadillac crest; when a reader asked if he could have them back, de Nysschen said, "No, you can't have them back. I play with them each night in my bath." Head over to Jalopnik for the full read. It's worth it.

Cadillac CT6 uses aluminum to save 200 pounds

In Cadillac's recently launched ad campaign, the luxury brand's tagline is "Dare Greatly," and the two words suggest a brand willing to take big swings, even if they don't always connect. From what the company is promising, the forthcoming CT6 seems like an embodiment of that new motto. With an eventual range of turbocharged engines, reportedly including a turbo V8, a possible plug-in hybrid and streaming rearview mirror, the sedan is certainly pitched as tech showcase. Of course, extensive use of aluminum is practically mandatory to play in the luxury field these days, and Caddy is proving its latest creation can do that too. Despite the weighty appearance of the sedan's squared-off exterior, 64 percent of the CT6 is aluminum, including the entire exterior. Caddy claims that using so much of the lightweight metal sheds 198 pounds off the scales compared to using conventional steel. There still is some steel in the CT6; although it's predominately the high-strength variety. The engineers use the heavier metal for portions around the cabin and B-pillar for added safety. Cadillac also claims using steel "close-out panels" on lower portions of the sedan make the cabin quieter without needing as much sound deadening. The buildup to the CT6's public unveiling has been a long time coming after Cadillac pinned the flagship (for now) sedan's debut at the New York Auto Show nearly a year ago. When the sheet finally comes off on March 31, we get the first good idea about just how great Caddy's latest act of daring really is. Cadillac CT6 Elevates the Science of Mass Efficiency 2015-03-13 Technology DETROIT – Cadillac will use an advanced mixed-material approach for the lightweight body structure of the upcoming CT6 range-topping sedan. The structure is aluminum intensive, but the new Cadillac also includes 13 different materials customized for each area of the car to simultaneously advance driving dynamics, fuel economy and cabin quietness. The CT6 will debut March 31 at the New York International Auto Show and go into production late this year at General Motors' Detroit-Hamtramck assembly plant. "This is the rocket science of automobile construction and manufacturing today," said Cadillac President Johan de Nysschen.

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.
