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 ATS Coupe spy photos show more sedate two-door

Remember when the Cadillac CTS Coupe debuted, and we were all like, "Oh hello there?" Well, don't expect the same thing to happen when the new ATS Coupe is unveiled - these brand new (overexposed) spy shots show a two-door that's decidedly more sedate than the angular yet curvaceous and all-around good-looking CTS Coupe. This isn't to say that the smaller Caddy Coupe won't be attractive - the four-door version is plenty pretty, to be sure - it just likely won't have that extra somethin'-somethin' to truly set it apart from the sedan.
Fine, then. We don't doubt that the two-door ATS will be just as enjoyable to drive as its sedan sibling, with a lot of the mechanical stuff likely carrying over unchanged. That includes the powertrain options, meaning buyers will be able to choose from the naturally aspirated 2.5-liter inline-four, turbocharged 2.0-liter four, or larger free-breathing 3.6-liter V6.
Look for the 2014 ATS Coupe to enter production in January of next year, meaning a reveal later this year (LA Auto Show, perhaps?) would be in order.
