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.

Dodge Dart falls short of Consumer Reports Recommended, Caddy XTS and Lincoln MKS, too

The Dodge Dart, Cadillac XTS and Lincoln MKS all failed to earn a "Recommended" rating from Consumer Reports. When it came to the compact Dart, the organization's testers thought the vehicle offered a quiet cabin, solid-feeling chassis and nimble suspension, but the new model ultimately fell short of the coveted rating due to powertrain issues. The institute's reviewers found the base 2.0-liter four-cylinder engine to be underpowered and noted "drivability issues" when the available turbocharged 1.4-liter four was paired with the optional dual-clutch transmission (some of our editors disliked it paired with the six-speed manual). CR also dinged the latter powerplant for sounding "raspy." For what it's worth, we think the forced-induction engine offers an excellent and playful exhaust note, but that's just us.
As for the XTS, CR lauded the car for its luxurious cabin, but the vehicle's experience was dulled by its finicky CUE infotainment interface. Overall, the big Cadillac scored much higher than its cross-town rival from Lincoln. While testers found the American luxury sedan to offer a quiet ride and quality fit and finish, they felt the MKS delivered a "cramped driving position, ungainly handling, uncomposed ride, and limited visibility." Ouch. At the end of the day, both cars fell short of rivals from Japan, Germany and Korea. Check out the full press release below with more details, along with CR's musings on the Chevrolet Spark and Lexus ES.

Cadillac confirms CT8/CT9 flagship, ELR successor

Cadillac has certainly been a hot topic as of late, what with Johan de Nysschen now running the joint, moving its headquarters to New York, and overhauling the company's naming structure (only to later publicly defend all of these drastic decisions). Now, looking ahead, de Nysschen is already revealing some details about what's in store for the future, including a raft of new products that include a large, long-wheelbase Mercedes-Benz S-Class rival positioned above the recently announced CT6, along with a successor to the slow-selling ELR coupe.
In an interview with Reuters, de Nysschen says his company has "just signed off on" a new flagship tipped to be called CT8 or CT9. It will compete with the long-wheelbase versions of the Mercedes-Benz S-Class and BMW 7 Series, and should come to market by the end of this decade.
Among other news, the South African executive said a followup to the ELR plug-in hybrid is in development, though it may not be a two-door coupe like the current car. That's not necessarily a bad thing, since the ELR has garnered nothing but slow sales and poor reviews since its launch.
