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 puts e-commerce shopping in car dashboards

DETROIT — General Motors on Tuesday said it will equip newer cars with in-dash e-commerce technology, betting it can profit as drivers order food, find fuel or reserve hotel rooms by tapping icons on the dashboard screen, instead of using smartphones while driving. GM's Marketplace technology, developed with IBM, will be uploaded automatically to about 1.9 million model-year 2017 and later vehicles starting immediately, with about 4 million vehicles across the Chevrolet, Buick, GMC and Cadillac brands equipped with the capability in the United States by the end of 2018, GM said. GM will get an undisclosed amount of revenue from merchants featured on its in-dash Marketplace, Santiago Chamorro, GM vice president for global connected customer experience, said during a briefing for reporters. Customers will not be charged for using the service or the data transmitted to and from the car while making transactions, he said. "This platform is financed by the merchants," Chamorro said. GM will get paid for placing a merchant's application on its screens, and "there's some level of revenue sharing" based on each transaction, he said. It is too soon to say how much revenue GM could realize from the Marketplace system, he said. The GM Marketplace will compete for customer clicks and revenue with hand-held smartphones, which offer a far richer array of applications than the GM system will at the outset. Amazon.com is partnering with other automakers, including Ford, to offer in-car e-commerce capability through Amazon's Alexa personal assistant system. For example, GM will launch Marketplace with just Shell and Exxon Mobil icons in the fuel category. The only restaurant available for in-car table reservations at launch is the chain TGI Fridays, GM said. In addition, there will be apps for parking, and ordering ahead at coffee shops and restaurants such as Starbucks, Dunkin' Donuts and Applebee's. "We will be adding more vendors," with some coming in the first quarter of 2018, Chamorro said. In addition, he said GM plans to expand integration into its vehicles of music, news and other information services. GM also hopes to use its in-car Marketplace connections to expand purchases of products and services, such as additional access to in-car wifi, from its own replacement parts business and dealer network. Customers can "expect to see more service promotions coming through the platform," Chamorro said. Reporting by Joe WhiteRelated Video:

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.
