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 to fight Audi A3, Mercedes CLA with small rear-drive sedan?

Compact luxury sedans are fast becoming the trend among upscale automakers. Mercedes has the new CLA (and its many platform-mates), BMW has the 1 Series and 2 Series, Audi has the A3 and, though Lexus apparently isn't interested in anything smaller than its CT 200h, Infiniti is getting in on the action with a compact model of its own. It would only follow logically, then, that Cadillac should launch a competitor, and according to the latest reports, that's just what it has in store.
Speaking with Car and Driver, Cadillac marketing chief Uwe Ellinghaus confirmed that such a project is in the works. But unlike its rivals, Cadillac aims to go with a rear-wheel-drive layout. This despite research that apparently indicates that a surprising 80 percent of owners think that their BMW 1 Series is front-drive. It's the driving dynamics and styling proportions that motivate Ellinghaus and his colleagues to stick with rear-drive, however.
The new model would in all likelihood be based on the same GM Alpha architecture that underpins the ATS and CTS - a platform that has helped Cadillac keep the weight down on both models and which is expected to underpin the next-generation Chevy Camaro, as well. The sub-ATS could be positioned as a four-door 2+2, however, as the ATS grows a little larger in its next iteration in order to make room for its new baby brother.

Mercedes leads in US luxury car thefts

Mercedes-Benz makes some fine automobiles. The Silver Arrow'd cars are so good, apparently, that thieves can't help but try to steal them. The German brand is at the top of the charts for luxury car thefts in the US, according to the National Insurance Crime Bureau, with New York City leading the way. (And those New Yorkers complain about Detroit being bad!)
The C-Class was the most stolen model, with 485 ganked between 2009 and 2012 in NYC alone, while the E-Class and S-Class (which also boasted the worst recovery rate, at 59 percent) both finished in the top ten. Following the C-Class was the BMW 3 Series and Infiniti G. Not surprisingly, each of these were the most common models in their respective lineups. Los Angeles and Miami are also prime hotspots for luxury car thefts, according to the Detroit News report.
While getting your car stolen is pretty awful, there was one inspiring statistic compiled by the NICB - the average recovery rate across the board was 84 percent, with the Cadillac CTS getting recovered 91 percent of the time.
