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.

Shatner's Rivet motorcycle to enter limited production with CTS-V engine [w/video]

William Shatner has entertained the world for decades, from playing Captain Kirk on Star Trek to covering songs like Rocket Man and Common People. Now in his 80s, Billy Shatz has embarked on one of his weirdest projects yet: helping to design the wild Rivet One trike with motorcycle fabrication company American Wrench. Now, you can order one too with power as crazy as the three-wheeler's design. We last saw the Rivet One's aluminum body with the styling like a menacing, art-deco easy chair a few months ago, but now Shatner has started talking about the trike's powerplant, which is based around the heart of a Cadillac CTS-V. "It's a beast with advanced guts. It's powered by an all-aluminum, computer-controlled, supercharged and intercooled V8 engine – producing over 500 HP," Shatner said to Gizmag. Keep an eye out because Shatner intends to captain the Rivet One from Chicago to Los Angeles later this year. Also, if you want a ride like Captain James T. Kirk, the company is taking requests for the trike, made on a build-to-order basis after completing Shatner's job, according to Gizmag. Prices aren't announced yet but expect the number to be as out of this world as a voyage of the Enterprise. The video below provides a further look at the Rivet One's unconventional design.
