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 chief marketer admits ELR is 'a big disappointment'

During the Cadillac XT5 global launch in Dubai, Automobile interviewed Cadillac Chief Marketing Officer Uwe Ellinghaus and got the CMO to touch on just about every major issue affecting the brand and the industry. After two years on the job, having come from 15 years at BMW, Ellinghaus naturally started with the "passionate Cadillac customers" and "iconic brand" spiel, then they got into a top-down look at where America's preeminent luxury brand stands. Ellinghaus said Cadillac is in a period of transition, lately focused on smaller and more performance-oriented vehicles, which has alienated a chunk of veteran customers and left others trying to figure out what Cadillac is about. He believes that "for a few more years, the products will probably be stronger than the brand," while he does his work of conveying what the company has to offer. But the brand had to make the switch, because "Generation X and Y will make 80 percent of all actual buyers in the next five years..." On top of that, he'll be working on making sure the customer and dealership experiences are where they need to be. Speaking of dealers, Ellinghaus thinks the future will not be brick-and-mortar shops, but digital pickup-and-delivery services. "Nobody wants to go to a dealership for service and maintenance," he says. He said the ELR has been "a big disappointment," but it has taught Cadillac that converting its existing line-up to plug-in hybrids is a better way forward. However, he characterized the plug-in hybrid as "the next all-wheel drive," in that everyone's going to offer it soon, so it will be "an entry ticket into luxury automobiles rather than a differentiating aspect." The CMO thinks the CTS is suffering because of the decline in the US midsize luxury sedan market in general thanks to the SUV and crossover craze, so the brand really needs another small SUV. Head over to Automobile for more of Ellinghaus' intriguing answers, like "I do believe that very long-term hydrogen is really the way," and "it's time to get real" in Europe. Taking a dig at Volkswagen on that last matter, he also said, "I think the absence of the diesel is not as much of an issue as it was eight weeks ago." Related Video:
