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.

GM to accelerate its EV strategy — Cadillac could be all-electric by 2025

General Motors will roll out details of an expanded and accelerated electric vehicle strategy on Thursday in an effort to convince investors it can be a serious competitor to Tesla, people familiar with the plans said. GM Chief Executive Mary Barra, who is scheduled to speak at a conference hosted by Barclays, is expected to say the automaker is ready to spend more on electric models by 2025 than the $20 billion previously outlined, the sources said. Supplier sources said previous plans to make the Cadillac brand all-electric by 2030 are being sped up, possibly to 2025, and other sources said that acceleration will be repeated in other brands and in segments such as commercial vans. Asked about the Thursday appearance, a GM spokeswoman called talk of increased spending speculative and declined to give details. The Detroit automaker is also expected to discuss a new timeline for many of the EVs to follow those already identified, such as the GMC Hummer EV pickup and Cadillac Lyriq crossover, people familiar with the plans said. Lyriq (shown above) is slated to go into production in late 2022, but GM officials have been stung by criticism the automaker was bringing the vehicle to market too late, one source said. "The pull-ahead in programs is real and the organization is really doubling down on speeding up product development," the source said. Barra and other GM executives have been signaling the automaker's EV acceleration plans. She said earlier this month GM would boost capital spending over the next three years to speed EV development and was talking with other automakers about partnerships to develop more vehicles using GM's battery technology. Last week, a GM executive said the company had pulled forward the rollout of two "major" EV programs, and GM officials have touted the faster 18-month development time for the Hummer truck. Tesla's soaring market capitalization, and growing pressure from regulators to phase out carbon-emitting engines, has put pressure on established automakers to respond to investors who view their internal combustion lineups as outmoded and doomed in the long run. A critical part of GM's pitch to investors has been its new Ultium batteries, which it estimates will offer an electric driving range of 400 miles or more on a single charge. It is building a battery plant with Korean battery maker LG Chem in northeast Ohio.

Cadillac confirms 420-hp twin-turbo V6 for 2014 CTS [w/videos]

The 2014 CTS will break cover next week at the New York Auto Show, but Cadillac has released a few details of what we can expect to find under the car's hood. As we saw in some spy shots back in January, the biggest news for the midsize Caddy will be a twin-turbocharged V6 producing a whopping 420 horsepower and 430 pound-feet of torque.
This LF3 engine will be paired to a new eight-speed automatic transmission, which will help balance performance and fuel economy. We still don't know how much the 2014 CTS has grown in terms of size and weight, but General Motors says that new sedan will return 17 miles per gallon in the city and 25 mpg highway with the new engine to go with a 0-60 mile per hour time of 4.6 seconds - that means the new CTS will have the fuel economy close to the current base model sedan and acceleration not too far from the current CTS-V. General Motors also confirmed that this twin-turbo V6 will be available in the 2014 XTS this fall.
The next-generation CTS will carry over the 3.6-liter V6 from the current car (likely as a base engine) and also add the 2.0-liter turbo four-cylinder from the ATS. Check out all the details on this new engine and watch a few videos (including GM's nifty tilt rig) by scrolling below.
