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 SRX and Saab 9-4X recalled for suspension defect

General Motors has recalled 380,498 vehicles due to rear suspension toe link adjusters that may not have been tightened properly, which could result in a loose toe link. The vehicles affected by the recall are Cadillac SRX crossovers built between 2010 and 2016, and Saab 9-4X crossovers built in 2011 and 2012. A loose toe link could cause instability while driving, especially at highway speeds. This recall follows up an investigation by the National Highway Traffic Safety Administration after it received complaints from SRX drivers of uncontrolled swaying while driving. According to the agency, two incidents led to a crash. It's possible that improper procedures for tightening a toe link nut during four-wheel alignments may have resulted in corrosion and thread wear on the adjustable portion of the link. Owners of affected vehicles are advised to park their crossovers if they experience certain Malfunction Indicator Lamp warnings on the dashboard or if they feel unusual steering behavior while driving. According to the official NHTSA recall notice, dealers will replace the adjustable toe link with a non-adjustable one at no charge. Letters are expected to be mailed to owners of affected vehicles on August 9, 2021. Alternatively, owners can call Cadillac customer service at 1-800-458-8006 or Saab customer service at 1-800-955-9007 and reference recall number N212340980. This is the second time many of these vehicles have been recalled for problems with the rear toe links. Back in September of 2014, GM announced that it would recall 290,241 vehicles that included SRX and 9-4X models because a "nut in the rear suspension toe adjuster link may not be torqued to the proper specification." 

Cadillac abandons plans for six-digit flagship sedan

So much for that party. Cadillac has announced that it is walking away from plans to build a high-dollar, rear-wheel-drive ultraluxury sedan. The low-volume model would have been based on the lusty Ciel Concept, and the production iteration would have carried a price tag well over $100,000. Executives with the automaker reportedly claim the model wouldn't have bolstered the brand enough to be worth the investment.
Even so, Automotive News reports Cadillac is still on track to build a range-topping four-door to go head-to-head with the BMW 7 Series and Mercedes-Benz S-Class. That model will likely be constructed on the company's upcoming Omega rear-wheel-drive platform, but we won't see it bow until at least 2016. Right now, the front-wheel-drive XTS sits at the top of the Cadillac lineup, and while that machine and it's twin-turbocharged V6 variant makes a compelling argument against certain luxury entries, it falls short serving as a legitimate competitor for the likes of the 7 Series and S-Class for enthusiast drivers.
