2016 Cadillac CT6 to get an aluminum body?

Well this is interesting: A hot-off-the-press report in Automobile claims the coming Cadillac CT6 will have an aluminum body. Most write-ups on the CT6 claim it will have a body that's a combination of aluminum and high-strength steel - Automobile itself wrote of "high-strength steel, aluminum, and steel stampings" in October. An all-aluminum body would be quite the reversal, contradicting the last four months of reportage and company statements on the matter. Mark Reuss, EVP of global development at General Motors, told The Detroit News in October, "We will create with the CT6, the world's most advanced body structure... [and] it's not aluminum. It's a stronger, smarter, safer premium luxury vehicle." It echoed the earlier Automobile story in saying the CT6 would use GM's "patented welding technology with high-strength steel, aluminum and steel stampings and castings." That same month, the Wall Street Journal ran a piece titled, "GM Won't Follow Aluminum Strategy in Future Cars," in which Reuss said, "making big statements around all carbon fiber, all aluminum, all magnesium, they're very interesting," and that GM wouldn't be doing it. That piece also circled back to a material mix and GM's special welding process, saying the CT6 "will have a body made of aluminum, high-strength steel and other materials, and will be 100 kilograms (220 pounds) lighter than a similar-sized car made of high-strength steel." We don't know what kind of body Cadillac's new assault on luxury is going to wear, but now we can't wait to find out.

How Cadillac improved power output in 2016 ELR by 25 percent

Earlier this year, Cadillac announced that the 2016 ELR would come with a big price drop and a powertrain that packs 25 percent more power output. That's a lot more oomph, but it didn't sound like the Caddy engineers made any major changes to the engine or motors. So, what happened? Let's refresh our memories with the numeric details. The 2016 car is 1.5 seconds quicker to 60 miles per hour than the 2014 model (there was no 2015), down to 6.4 seconds. The 2014 put out 295 pound-feet of torque. For 2016, it will be 373 lb-ft. The specific breakdown of the various components in the powertrain has not been disclosed, but from what we can tell, the two electric motors and the 1.4-liter inline-four engine in the new ELR are not that much different than those in the old one. Sam Abuelsamid, senior research analyst at Navigant Research (and former writer here at Autoblog) said that any of the unspecified upgrades would be difficult to tell on a part-by-part basis, but the overall effect will be noticeable. "The changes to the ELR as I understand them are analogous to getting more performance out of a 1965 Mustang with the entry version of the 289 cubic-inch V8. You can replace the carburetor with a larger version that enables more air and fuel to flow into the engine, thus producing more power. The basic engine hasn't changed, but power capability is being unleashed by feeding it more." "Cadillac has changed components in the power electronics to enable more current flow into the motor and thus produce more torque. When you do this in the Mustang, you probably need to replace the rear axle gears and use a beefier clutch to transmit the power to the wheels. Similarly, the ELR probably has some upgraded clutches, bearings, and gears to withstand the increased total output." Cadillac spokesperson David Caldwell told AutoblogGreen in an email that the new ELR does indeed have more than just new lines of code. "One could not 'reflash' a previous ELR to get the performance of a 2016," Caldwell said. "If one only changed software you would not get the performance upgrade fully, as the 2016 creates higher current, more power. So these have been upgraded physically – hardware.

Cadillac to add small sedan, crossover as part of major product blitz

Cadillac will add a small sedan and a compact crossover to its lineup in the next several years as part of an ambitious product blitz that will remake its lineup. The sedan will slot below the ATS, which is currently Cadillac's smallest four-door car. It's scheduled to arrive in 2017, Cadillac president Johan de Nysschen told Autoblog at the Detroit Auto Show. The sedan will be followed late that year or in early 2018 by a compact crossover, which will be positioned below the SRX. The crucial redesign of the SRX – Cadillac's top seller – arrives in 2016. It will switch to the brand's new naming system and change to an "XT" prefix followed by a number. The naming scheme debuts on the CT6, which launches in late 2015 and will be positioned above the CTS and XTS sedans. Cadillac also wants to add another crossover that sits between the SRX and its flagship SUV, the Escalade, at some point. Further out, Cadillac's long-awaited Mercedes-Benz S-Class fighter could arrive around 2020, and it would serve as the flagship or "showcase of the brand," de Nysschen said. Cadillac is also looking to expand its powertrain portfolio and is contemplating a wide range of options, including hybrids, plug-in electric vehicles and diesel engines. The new cars and crossovers are part of a $12-billion investment in Cadillac, which de Nysschen described as "an unheard level of capital" from General Motors. In total, the brand will receive eight new products through 2020. "Our product offensive will provide the substance for our ambitions," he said. De Nysschen has set high goals – and made major changes – at Cadillac since he took over the 113-year-old luxury brand in September. The brand moves to a separate headquarters in New York this year, away from GM's base in Detroit, and it has switched advertising agencies in a bid to elevate its image. Cadillac's sales declined 6.5 percent in the United States in 2014 to 170,750 units, and it has the smallest volume of GM's four brands. "Here in the US we continue to make progress, but we also face challenges," de Nysschen said. He added the brand's lineup "clearly limits our growth opportunities in the US market." Still, de Nysschen is taking the long view for Cadillac, noting it took years to turn around Audi, where he was president of its US operations for eight years. Cadillac's global sales have inched up five percent globally this year, spurred by a 47-percent surge in China.
