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.

Cadillac ATS-V Coupe caught undisguised ahead of LA reveal

Vsport versions of the CTS and XTS sedans are all well and good, but what Cadillac enthusiasts have really been looking forward to is the arrival of the next full-on V model. And here we have it.
Spied in the nude during an apparent photo shoot ahead of its anticipated debut at the fast-approaching Los Angeles Auto Show, the upcoming new Cadillac ATS-V Coupe is set to pick up where the old CTS-V left off, only in a more compact form. Unlike previous spy shots of heavily disguised prototypes, this final version is showing a chrome-framed mesh grille, along with a deep lower air dam with what looks to be a carbon-fiber front splitter. That bulging hood with heat extractor vents is tipped to be packing a twin-turbo V6 engine, breathing out of quad exhaust tips.
The aggressive aero kit also encompasses side skirts, a reshaped rear bumper and a lip spoiler on the truck, while the upgraded rolling stock wears serious low-profile rubber and the brakes appear to be carbon-ceramic units. Peer through the window and you can even see the sport bucket seats with slots for racing harnesses. All of which suggests a serious American challenger to the BMW M4 and its ilk, and we're looking forward to seeing the vehicle in the metal in LA next month.

GM invests $175 million to replace 3 Cadillac sedans with 2

We've already had confirmation that Cadillac is sunsetting the ATS compact sedan and strong hints that Caddy would discontinue the full-size XTS (pictured above) and midsize CTS, too. Now all three are confirmed, with GM saying it's investing $175 million to build two replacement sedans. GM has already begun installing new tooling at its Lansing Grand River assembly plant in Michigan. That will go toward building two new sedans, which reports suggest are likely to be called the Cadillac CT5 and CT4, or possibly the CT3. It's part of Cadillac's plan to introduce a new vehicle every six months by the end of 2021. A spokesman told the Associated Press that the new cars will debut within that time frame and that the changes won't affect staffing levels at the plant, which employs 2,000 people. Of the three, the XTS is expected to go away entirely, while the CT5 would replace the CTS, straddling the line between a compact and midsize four-door. The CT4 or CT3 would take the spot of the ATS and likely be smaller. That would leave the CT6 as the brand's largest sedan and leave Cadillac with three sedans starting with the 2019 model year. Meanwhile, Cadillac has only one model, its top-selling XT5, representing the all-important and red-hot luxury crossover segment. It's prepping a midsize XT4 crossover for sale later this year as a 2019 model. Cadillac's global sales rose 15.5 percent in 2017, thanks largely to growth in China, but sales in the U.S. fell 8 percent for the year to 156,440 vehicles. Sales of the ATS fell 39 percent, dropped 35 percent for the CTS and 27 for the XTS last year. Related Video:
