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.

Next Cadillac Escalade's interior spied for the first time

Update: Now that new spy photos of another large GM SUV have surfaced, we believe these shots show us a GMC Yukon interior, not a Cadillac Escalade. You can see the new spy shots here that depict a much more upscale vehicle interior compared to the fuzzy center stack shown in the shots of the Yukon. The new Cadillac Escalade has a lot of work to do in order to properly compete with Lincoln's wonderfully luxurious Navigator. These interior spy photos are our first look at what Cadillac is working with on the inside of its new luxury truck. We won't make final judgements, as this vehicle is still a prototype and subject to change. However, a few key bits are noticeable from the fuzzy photos. As expected, Cadillac's CUE infotainment and center stack is nowhere to be seen. Replacing it is a new interior design language, with a tablet-like screen that seems to rise out of the sloped stack on top. Below the screen is a strip of stitched leather and a couple prominently placed air vents. To the left of this area is what appears to be a push-button gear shifting system, replacing the column-mounted shifter currently in use. Below all that on a lower level of the center stack are all the climate controls, along with what look like physical buttons for what could be audio-related controls. Does it look as luxurious as the Lincoln? Not with all the coverings and shrouding it doesn't, which means we'll have to wait until we get the full picture. One thing that's clear is that the interior design is definitely going to be wildly different than the current Escalade. That center stack flows downward as one sloping piece into the high and bulky center console area. This design looks like it brings the center console further downward, and also uses a multi-tiered look. It's tough to read what's on the screen, but the software looks like the same stuff we got a preview of on the new Cadillac CT5 and CT4 sedans. As for the exterior shots, there's almost nothing that we haven't already gotten a taste of in previous spy photos. The independent rear suspension is a go, as are what appear to be massive headlight and LED DRL fixtures. If you look through the wrapping, you can make out how far up and down the lighting fixtures stretch ... or perhaps they're separate units altogether. It's tough to tell at this point.

Cadillac developing stretched ATS-L just for China

To luxury automakers, long-wheelbase sedans are to China that crossovers and SUVs are to the US, so it isn't all that surprising any more when the latest sedan gets an extra couple of inches between the wheels to improve rear-seat comfort. According to Car News China, the next sedan to get the stretch will be the Cadillac ATS, which will increase the wheelbase by 10 centimeters (about four inches) to become the ATS-L.
Designed to go up against rivals like the BMW 335Li and the added-length Mercedes C-Class, the ATS-L will reportedly be built locally in China with an engine list that will grow as well. Currently, only the 2.0-liter turbo engine is offered in the ATS in China, but the ATS-L will get the full spectrum of ATS engines including the base 2.5-liter and the peppier 3.6-liter V6. This isn't the first time Cadillac has offered a China-specific stretched sedan either as the SLS dates back to 2006.
