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 XT5 confirmed for 2016 as next-gen SRX

Cadillac's entire lineup of 2016 models gets a major infotainment upgrade this summer with improvements to CUE and integration with Apple CarPlay and Android Auto. There's one major exception for now, though. The SRX retains the old system until its all-new generation, called the XT5, debuts early in the 2016 calendar year. "When we transition into all new product lines, we will evolve the naming convention to suit the new classification we have announced. So SRX becomes XT5 next year," company spokesman David Caldwell said in an email to Autoblog. Earlier spy shots and rumors suggest the XT5 might be offered with a turbocharged four-cylinder and naturally aspirated six-cylinder engines, plus a nine-speed automatic transmission. For the rest of Cadillac's models, CarPlay arrives with the launch of the 2016 vehicles, and Android Auto joins later. Using either of them requires a connection via USB, and they add a new projection icon on the CUE screen. Once activated, both systems integrate with driver's phone and incorporate features like navigation, music, and contacts. They can also accept voice commands. Even for those that don't want to hook up a smartphone, CUE should work better thanks to a more powerful processor. Start-up times for the infotainment system are expected to be faster, and Cadillac claims that it's also more responsive for voice recognition, navigation searches, and media. The navigation interface is simplified, as well. The Escalade, CTS, and XTS can now be ordered with a 360-degree camera system to display on the screen. Cadillac Enhances Phone Integration for 2016 Models with Apple CarPlay, CUE Upgrades APPLE CARPLAY AVAILABLE AT LAUNCH; ANDROID AUTO COMING LATER IN MODEL YEAR 2015-06-09 NEW YORK – Cadillac's 2016 model year products will feature enhanced connectivity and control, including the addition of Apple CarPlay and Android Auto, the predominant new systems for in-car phone integration. These additions are part of a broader enhancement of CUE, Cadillac's user experience, with new features and a faster, streamlined operation. Apple CarPlay will debut in 2016 Cadillac models featuring CUE's 8-in multi-touch screen except the SRX Crossover, a model that will move to an all-new generation in early 2016. Android Auto is expected to be phased into 2016 production at a later date. The 2016 model year will begin this summer.

Reuss says Cadillac CT6-based Buick could happen

Could the upcoming Cadillac CT6 and its Omega platform spawn a Buick variant? According to General Motors' product chief Mark Reuss, it could potentially be in the cards, but "not yet." "We're working on that," Reuss told Automotive News at the 2015 New York Auto Show. While there hasn't been a large, rear-drive Buick on dealerships since the Roadmaster in 1996, the company gave a big hint that it could head in that direction with the Avenir Concept, shown earlier this year at the Detroit Auto Show. As Automotive News explains, a rear-drive Omega-platform Buick could be a real hit in China, where consumers buy 13 Buicks for every one Cadillac. That move would be a big help to GM's bottom line, too, as it'd significantly increase the Omega platform's economy of scale. If a large Buick based on the CT6 were to head to China, though, it likely wouldn't be a simple case of badge engineering (thank God). Reuss hinted to Automotive News that while the mixed-material construction of the CT6 platform "is very flexible," doing an "identical version of that platform or not is a different conversation." What are your thoughts? Should Buick adopt the Omega platform for an Avenir-based sedan? Should that vehicle be sold here in the US, or should it be a China-only offering? Have your say in Comments.
