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 applies to trademark Symboliq, Optiq and Celestiq names

GM Authority found a General Motors trademark filing with the Swiss Federal Institute of Intellectual Property for the phrase "Cadillac Symboliq" and the name "Symboliq." The documents submitted on July 22 were for the category of "Motorized land vehicles, namely automobiles.” It appears the Swiss action was GM following up on what it had done the day before in the U.S. On July 21, GM filed paperwork with the U.S. Patent and Trademark Office to secure three words and three phrases: Symboliq and Cadillac Symboliq, Optiq and Cadillac Optiq, and Celestiq and Cadillac Celestiq. Every name is listed for application to "Motor land vehicles, namely, automobiles." Cadillac recently explained its switch to model names that end in "iq," pronounced "ick," and the fact that the Celestiq name is among the recent trio leads us to believe the automaker has strong intent to use the other two on future products. We know the Celestiq — a large, hand-built, flagship sedan that will follow the Lyriq to market, predicted to retail for close to $200,000 whenever it goes on sale. We also know Cadillac has three more battery-electric products in the works after the XT5-sized Lyriq and "massive" Celestiq. As laid out in a 2019 GM Sustainability Report pitching 20 new electric vehicles across all brands by 2023, from Cadillac we're anticipating an XT4-sized crossover, an XT6-sized three-row crossover, and an electric take on the Escalade. Two of those three could get the Symboliq and Optiq names. The lineup, and more important, Cadillac's vision, will make more sense on August 6 when we finally get to see the Lyriq concept, with its single pane of 33-inch glass forming the instrument and infotainment display across the dash, tall taillights, and 22-inch wheels.   Related Video:

7 major automakers to build open EV charging network

A new joint venture established by BMW, GM, Honda, Hyundai, Kia, Mercedes-Benz and Stellantis will build a new North American electric vehicle charging network on a scale designed to compete with Tesla's industry-benchmark Supercharger network. The 30,000-plus planned new chargers will accommodate both Tesla's almost-standard North American Charging System (NACS) and existing automakers' Combined Charging System (CCS) options, effectively guaranteeing compatibility with the vast majority of current and upcoming electric models — whether they're from one of the involved automakers or not.  "With the generational investments in public charging being implemented on the Federal and State level, the joint venture will leverage public and private funds to accelerate the installation of high-powered charging for customers. The new charging stations will be accessible to all battery-powered electric vehicles from any automaker using Combined Charging System (CCS) or North American Charging Standard (NACS) and are expected to meet or exceed the spirit and requirements of the U.S. National Electric Vehicle Infrastructure (NEVI) program." Critically, the automakers involved will have a say in how the charging tech is implemented, guaranteeing that the hardware will play nicely with each automaker's in-house charging systems. Hyundai and Kia, for example, were hesitant to jump on board the Tesla NACS bandwagon earlier this year over concerns that the Supercharger network is insufficient for powering the two automakers' 800-volt charging systems; similar tech is used by Volkswagen and Porsche.  In addition to providing much-needed capacity and high-output charging for America's growing fleet of electric cars and trucks, the new network will integrate seamlessly with each automaker's in-app and in-vehicle features, rather than forcing customers to use third-party tools and payment systems, as is the case with some existing public charging infrastructure.  "The functions and services of the network will allow for seamless integration with participating automakersÂ’ in-vehicle and in-app experiences, including reservations, intelligent route planning and navigation, payment applications, transparent energy management and more. In addition, the network will leverage Plug & Charge technology to further enhance the customer experience," the announcement said.
