Cadillac Elmiraj Concept slinks in Leno's Garage

Jay Leno's Garage has moved to Pebble Beach for the week. This time around, the affable comedian is taking a look at the Cadillac Elmiraj Concept that debuted during the Monterey car week, and is talking to General Motors vice president of global design, Ed Welburn.
There's plenty of reminiscing about what concept cars were like when these two were kids, before a fairly deep dive into the striking Elmiraj Concept itself. Welburn shares a few anecdotes about the design process behind the two-door concept, including how his designers changed his mind on the grille design.
After bringing up the Cimarron, Leno makes a solid point that the Elmiraj would be a solid production car that could even spawn a four-door variant. We couldn't agree more. Take a look below for the full video from Jay Leno's Garage.

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 president de Nysschen says electrification coming 'across the spectrum'

We like to pick on new Cadillac president Johan de Nysschen for his insistence, many years ago, when he was president of Audi of America, that plug-in vehicles are for idiots. Listening to him give the keynote address at the Washington Auto Show today, you wouldn't know he ever said anything negative about an electric vehicle. Instead, he sounds something like a EV-angelist. De Nysschen said that Cadillac will be able to benefit from GM's considerable expertise in plug-in technology, which he said would be "applied across the spectrum of our portfolio." GM's electric committment will help in "making electrification commonplace." With the plug-in ELR already on the road, de Nysschen said that the company's next step in advancing powertrains will be the introduction of stop/start technology – which de Nysschen called an "important system to reduce fuel consumption and CO2 emissions" – into a Cadillac for the first time later this year. Without giving any specific details, de Nysschen said that Cadillac will introduce eight new models (not necessarily plug-ins) by the end of this decade, including five that "will take Cadillac into market segments where the brand is not even present today." These new vehicles will likely be much lighter than today's vehicles, de Nysschen said, because "weight reduction today is critical to automotive design, it helps to improve fuel efficiency and contributes to desireable vehicle dynamics." The key is to reduce weight without compromising safety or comfort and to use the right material – steel, aluminum, carbon fiber – in the right place at the right time. It was a not-so-subtle jab at Ford and its new aluminum F-150. "In the pursuit of weight reduction, some manufacturers have also opted for abandoning steel and have gone for an all-aluminum approach," he said. "At Cadillac, we believe that different materials each present particular advantages in specific applications. There is no single material that represents the optimum balance of the conflicting objectives of every single application." Related video:
