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.

South Dakota dealer filled to brim with classic cars

Other than the Sturgis Motorcycle Rally and Mount Rushmore, South Dakota isn't generally a hot topic, but that just means that cool stuff can hide in the open waiting to be discovered. Case in point: the classic car dealer Frankman Motor Company that operates three locations in Sioux Falls, SD.
Unearthed by the folks at Bring a Trailer, Frankman is a treasure trove of vintage, American iron. Their collection is full of the type of vehicles your irresponsible but cool uncle would show up with when you were a kid. Even better, these cars are priced at a level a working man can afford.
If you are lusting about a cruiser then Frankman has a 1956 Cadillac Deville Hard Top Sedan (pictured right) with 82,896 miles for $12,975. It's painted a color called Cascade Grey, but looks more like a pastel purple in pictures. While it needs some repairs to the accessories, the Caddy runs and drives, which is all you really need.

Cadillac's semi-autonomous Super Cruise pushed back to 2017

It looks like General Motors is discovering just how difficult it is to bring autonomous vehicle technology fit for public consumption to market. The company has pushed back the launch of its semi-autonomous Super Cruise technology by several months. Originally promised by CEO Mary Barra for a fall 2016 debut, Super Cruise was supposed to be offered first on the new CT6 sedan. Automotive News is reporting that won't be the case, following a statement from GM confirming that the new system would be pushed to sometime in 2017. At the very least, that's a several month delay. GM cited the need to get the system right and keep owners safe, which prevented a firm date for Super Cruise's debut. Product boss Mark Reuss was more blunt, though, telling AN, "It will come out when it is ready." Super Cruise would be one of the earliest examples of driverless tech to be put into public hands, following the introduction of Tesla's semi-autonomous AutoPilot system in 2015. Most other automakers experimenting with the autonomous vehicles don't foresee public sales until early in the next decade, including Toyota, Renault-Nissan, and Volvo. Before Barra suggested a 2016 debut, GM originally aimed to introduce its semi-autonomous system in 2020. Related Video:
