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.

Will attaching the electrodes re-animate Cadillac?

This announcement last week from General Motors —"Cadillac will be GM's lead electric vehicle brand"— followed quickly by the surprise reveal Sunday night of a Cadillac EV crossover, leads one to wonder whether this is a case of GM pulling out the defibrillator and hoping a full-on jolt of electricity will revive Cadillac from its ongoing diminution in the market. In 2018, Cadillac U.S. sales were 154,702 vehicles, which was down from the 156,440 it had sold in 2017. And the 2017 sales were down significantly from the 170,006 vehicles delivered by Cadillac in 2016. And that is down from the 175,267 sales of 2015. Sure, part of Cadillac's problem — one shared by some other OEMs — is that its sedans aren't selling. But if we put those to the side, realize that in 2018 sales of the venerable Escalade were down by 2.2 percent. Admittedly, that rig is a little old in the grille, and it's suddenly gotten strong competition from the Lincoln Navigator, so a sales decline isn't too surprising. But the XT5, the compact lux vehicle that was launched in 2016 as a model-year 2017 product, had an 11.3 percent decline in a segment that is doing nothing but growing. This is not promising. Although the argument at GM HQ might be that Cadillac can reinvent itself as a Tesla fighter, one of the things that isn't often noted about Tesla vis-a-vis other OEMs is that while sedan sales are generally down, Tesla, which had an estimated 2018 sales volume of 197,680 (according to Cleantechnica.com), made its numbers primarily with the Model 3 and Model S, both sedans, as it has just the Model X crossover. So it isn't just about vehicle architecture. It is going to take more than an electric SUV to change Cadillac's performance. But here's where circumstances can fall in Cadillac's favor. Scale can be highly beneficial to Cadillac versus Tesla. The Chinese market, even though it is weakening of late, will be largely predicated on "New Energy Vehicles," which means electrified and fully electric. And while Tesla only just now broke ground on a factory in China, LMC Automotive reports that as of December 2018, SAIC GM is already well-established there and is the third-largest vehicle manufacturer in China (behind SAIC Volkswagen and FAW Volkswagen). Cadillac is going to be able to take advantage of GM's global efforts in developing EVs, so soon the Cadillac showroom could be filled with an array of luxury EVs that may make even Tesla loyalists take another look.

BMW reclaims US luxury sales crown from Mercedes

The numbers, they are in: BMW has reclaimed the luxury-sales crown from Mercedes by a margin of 9,347 cars. Mercedes donned the king's headgear in 2013 after a strong final quarter of 2013 when the new CLA and S-Class poured out of dealerships. This year, led by the 3 Series/4 Series and X5, BMW sold 339,738 units – a 9.8-percent increase year-on-year. Mercedes, led by the C-Class and M-Class, saw its sales go up by 5.7 percent to 330,391 units. We'll have to wait a bit to see if there's another registrations-vs-sales challenge as in 2012, when BMW was anointed US luxury ruler. Behind them, a dark horse named Lexus nudged closer to the leading Teutons, selling 311,389 cars. The Japanese luxury automaker also had the biggest gain among the top three, its sales rising by 13.7 percent compared to 2013. Audi had the biggest sales of anyone among the top five, though, with a 15.2-percent gain to 182,011, which moved it a spot ahead of Cadillac; the Wreath-and-Crest brand dropped 6.5 percent to 170,750. Acura (167,843), Infiniti (117,300), and Lincoln (94,474) took the final positions. Speaking of Lincoln, sales at the once-mighty luxury marque stand as the mightiest jump of any on this list, up 15.6 percent. That's the power of Matthew McConaughey... and better cars and a new crossover, sure. So now that we're back to Round One of 2015, in case no one else has said it yet: "Ok, fight!"
