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.

Chinese-made Cadillac CT6 Plug-In starts US sales

General Motors has started US sales of the Cadillac CT6 Plug-In after taking its first domestic deliveries of the China-produced sedan last month. The model is GM's first new plug-in hybrid in the US since the automaker discontinued sales of the ELR extended-range plug-in last year. The arrival and sales, first reported by InsideEVs, were confirmed by Cadillac spokesman Andrew Lipman. Not surprisingly, the sedan isn't cheap, as the CT6 Plug-In is priced at $75,095, or almost $12,000 more than the gas-powered variant, though that figure doesn't include federal and state tax credits for electric vehicles. For that tab, buyers get a 335-horsepower luxury car that can go 31 miles on electricity alone, and 0-60 miles per hour in a little over 5 seconds. The model gives GM three plug-in vehicles to sell to the American public, or the same number US competitor Ford offers. InsideEVs estimates that about 100 of the sedans have been delivered to US dealers, so the car remains a relatively low-volume affair. By comparison, GM's Chevrolet division has sold 5,563 Volt extended-range plug-ins and 3,092 Bolt electric vehicles through March. Cadillac sold 534 units of the ELR in 2016 after moving 1,024 the previous year. GM opted to produce the plug-in hybrid in China because of that country's receptiveness to new models that feature alternative and environmentally friendlier powertrains. Additionally, such production shortens the distance to the CT6's battery maker LG Chem, which is producing the car's battery packs in South Korea. On that note, GM has previously estimated that the Cadillac CT6 Plug-In will move more units in China than in the US. Related Video:

GM recalls 3.8 million vehicles in North America due to braking issue

WASHINGTON — General Motors Co said Wednesday it was recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and that has been linked to 113 accidents and 13 injuries. The recall covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles. In late June, GM recalled 310,000 vehicles in Canada for the same issue. GM did not immediately explain why the Canadian recall occurred more than two months before it called back the vehicles in the United States. The recall was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted on Wednesday. The NHTSA opened a preliminary investigation into the issue last November, and said it had reports of nine related crashes and two injuries. It provided GM in July with additional field reports that prompted the automaker to open an investigation. GM said it could affect braking in "rare circumstances." The NHTSA said in a statement the "vehicles may experience brake boost failure, which would require increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance." GM said dealers will reprogram the electronic brake control module to improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Separately, GM said on Wednesday it is recalling 270,000 additional U.S. vehicles in three smaller recalls, including 177,000 2018 Chevrolet Malibu cars with 1.5L turbo engines because an error in the engine control module software may result in the fuel injectors being disabled.
