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.

President Trump might get to start his administration in a new Cadillac limo [UPDATE]

(UPDATE: Jalopnik is reporting an unidentified source claimed the new limo would not be featured in today's inauguration ceremony. The source did say however that the limo would join the presidential fleet later this year.) A rumor is going around that President-Elect Donald Trump will have a brand new set of wheels the day he takes office. The Cadillac Presidential Limousine, nicknamed "The Beast," was last refreshed in 2009 and led President Barack Obama's second inauguration-day parade. Cadillac could not confirm any timeline for the new presidential limo, nor could it confirm any specifics about the car nicknamed Beast 2.0. That's as expected, because details on the presidential limo are closely guarded and considered matters of national security. The outgoing original "Beast" limo marked a switch to a custom-built vehicle based on a General Motors truck frame. Previous limos were based on the actual cars they looked like. As we've seen in spy shots, The Beast 2.0 limo looks more like an Escalade SUV or CT6 sedan but is reported to be roughly the same size and shape as the old Beast, which is built on a Chevrolet Kodiak/GMC TopKick medium-duty truck chassis. AutoWeek is reporting that the new limo is set to debut for Trump's inauguration, however those reports could not be confirmed for the reasons mentioned above. The new Presidential car is expected to accommodate seven passengers in conference-style seating in the back like the current version. The Beast isn't meant for road trips, as it is mostly used to ferry the President to and from Air Force One when traveling, or on short trips around Washington D.C. That's good, considering the current limo only gets 3.7 miles per gallon. Along with multiple screens for video conferencing, The next Beast will also definitely include advanced armoring and weaponry. For security reasons, it's impossible to know the extent of those systems, but any vehicle transporting the most powerful man in the world around has to be tough. The entire process of designing and building the Presidential limo is top secret, as the Secret Service figures the less everyone knows about the Presidential Limo, the better. The new Beast, we can safely assume, is likely the safest vehicle in the world. The Secret Service began taking bids on building a replacement in 2014 because integrating all of the required armor is technically challenging.

2019 Autoblog Technology of the Year finalists revealed

Every fall, we line up a range of new models with the latest and most compelling automotive technology from the past year. We test everything from semi-autonomous systems like Tesla's Autopilot to trick suspension setups like the Multimatic spool-valve shocks on the Chevy Colorado ZR2. We spend months paring down the list to a small group of contenders. After testing, dinner and healthy debate, we tally up the votes and name our winner. For Autoblog's 2019 Technology of the Year Award, our three finalists are the Cadillac CT6 with Super Cruise, the Infiniti QX50 with Variable Compression Turbo and the Mercedes-AMG E 53 with EQ Boost. Super Cruise is an advanced SAE Level 2 semi-autonomous system, though Cadillac (unlike some of its rivals) is reluctant to push that point. Cadillac would like you to think of this as an advanced driver assistance feature rather than a semi-autonomous system. Super Cruise allows completely hands-free highway driving. Thanks to a driver-facing camera, the system forces the driver to keep his or her eyes on the road even if hands are off the wheel. Although the CT6 is being discontinued, look for Super Cruise to make its way to other Cadillacs soon. VC Turbo is a little more complicated. Basically, Infiniti's 2.0-liter turbocharged inline-four can vary the compression ratio on the fly. In general, turbocharged engines are more efficient than naturally-aspirated engines when on boost, but can perform worse at low revs. VC Turbo allows for a best-of-both-worlds situation, increasing the compression at low revs and backing it off once the turbo spools up. The best part is that it does so seamlessly, with only a dash readout letting you know what's going on under the hood. Our third finalist is the EQ Boost 48-volt system in the Mercedes-AMG E 53. Like VC Turbo, EQ Boost does a lot just beneath the surface. Mercedes has developed a new turbocharged 3.0-liter inline-six and paired it with a small electric motor. While the car can't run on electricity alone, the motor helps improve both efficiency and performance, smoothing shifts and filling in low-end torque before the turbos spool up. Think torque fill, similar to a McLaren P1. Who can complain about better fuel economy and more torque? Look for the 48-volt system to make its way into most of the Mercedes-Benz lineup. The winner will be revealed next week on Autoblog, and we'll present the award Jan. 15 at the Detroit Auto Show. Related Video:
