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 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.

Mystery Cadillac Escalade prototype spied testing on public roads

This mystery Cadillac Escalade prototype could be a rumored V model featuring a supercharged LT4 V8. This prototype, sporting a fancy exhaust and other unique elements under fairly elaborate camouflage, was spied testing on public roads in Michigan.  Since it's still quite comprehensively disguised, we can't say much for certain about what this prototype has going on underneath. We can see a new set of wheels, a quad-tip exhaust and what appears to be a redesigned lower front bumper, but our spies didn't indicate anything else definitive — not even the telltale whine of a supercharger. That seems a glaring omission, given that a V model would almost certainly be powered by the same supercharged V8 found in the CT5-V Blackwing, where it is expected to develop well north of 650 horsepower.  Cadillac chief engineer Tony Roma has previously suggested that more V-badged cars are in the pipeline without confirming which ones or when to expect them. An unverified report published in February 2021 claims the Escalade's 6.2-liter V8 will soon receive a 200-horsepower bump thanks to a factory-backed, dealer-installed supercharger; a full-fledged V model would take that formula a step further. If you're not familiar with Cadillac's latest performance offerings, "V" models are now the mid-range performance variants, similar to Audi's "S" cars in that they offer a bump in power and handling but stop short of being full-blown track monsters. That treatment is reserved for the new "Blackwing" nameplate, which was derived from the twin-turbocharged V8 of that same name that was originally slated to power those range-topping models.  Related video:
