Cadillac CT6 to be lighter than CTS, get PHEV model

Cadillac is suddenly one of the most talked about automakers in the US with Johan de Nysschen taking control. The brand claims that it eventually wants to become, once again, the standard of the world. One of the first vehicles to actually prove whether that's possible is its upcoming CT6 flagship sedan. We still don't know what the production version looks like undisguised, but other important details are falling into place. The latest big news sheds some light on the Caddy's powertrain and some estimates of its weight and size.
General Motors product chief Mark Reuss dropped the details at the automaker's Global Business Conference. According to The Detroit News, he revealed that the CT6 would use a twin-turbocharged, 3.0-liter six-cylinder engine with an eight-speed automatic transmission, and a plug-in hybrid would be an additional option. He reportedly claimed it would be the most "powerful six-cylinder gas engine in the segment" and said the hybrid could get around 70 miles per gallon.
Reuss also revealed that the CT6 would be about 53 pounds lighter than the current CTS, despite being about 8 inches longer, according to The Detroit News. If that's the case, the new flagship is about 203.5-inches long, which is 1.5-inches more than the XTS.

What will the next Presidential limo look like?

With recent news that the Secret Service has begun soliciting proposals for a new armored limousine, we've been wondering what the next presidential limo might look like. The current machine, nicknamed "The Beast", has a design based on a car that's no longer sold: the Cadillac DTS. If General Motors gets the job again, which wouldn't be a surprise considering the government still owns a chunk of the company, the next limo's shape would likely resemble the new XTS (below, left). But Cadillac hasn't always been the go-to car company for presidential whips.
Lincoln has actually provided far more presidential limousines throughout history than Cadillac. In fact, the first car modified for Commander-in-Chief-carrying duty was a 1939 Lincoln K-Series called "Sunshine Special" used by Franklin D. Roosevelt, and the last Lincoln used by a president was a 1989 Town Car ordered for George H.W. Bush. If President Obama wanted a Lincoln today, it would likely be an amalgam of the MKS sedan and MKT crossover, as illustrated above.
And what about Chrysler? The only record we could find of a President favoring the Pentastar is Nixon, who reportedly ordered two limos from the company during his administration in the '70s, and then another one, known today as the "K-Car limo," in the '80s after he left office. Obama, however, has a personal - if modest - connection to Chryslers, having owned a 300 himself before he took office. A 300-based Beast (above, right) would certainly earn the U.S. some style points.

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.
