GM will likely build PHEV batteries in China soon

It's a big week for batteries. Friday, Tesla will hold a big event at its Gigafactory in Reno, NV. But even in Michigan, there are things happening on the electrified automotive front. This was proven when GM invited journalists to its Brownstown Battery Assembly Plant today, highlighting the six different battery packs it makes for nine vehicles around the world (plus a tenth, coming to Asia, that has not yet been announced). During our tour, we learned a few interesting tidbits that we thought readers would like to hear: The Cadillac CT6 plug-in hybrid launches in China this fall before coming to the US next year. GM builds the battery packs in Michigan and ships them to China for final assembly in the PHEV. For now, this is all fine for GM to qualify for China's incentives for building green cars in the country. But, as Bill Wallace, GM's director of global battery systems, told AutoblogGreen, this could change thanks to the country's 'Made in China 2025' plan. The situation is "evolving," he said, and it's a safe assumption that GM will need to build packs in China some day. For the CT6 PHEVs that will be sold in the US, the batteries will make a round trip, since GM will only build the plug-in version in China. As for the range of the CT6 PHEV, that hasn't been announced, but since China offers incentives for vehicles that get at least 50 kilometers (31 miles), that's a likely target (the US range (UPDATE: GM did announce an expected range for the CT6 PHEV in the US at the LA Auto Show last fall, saying it would "travel approximately 30 miles on a full electric charge"). The battery pack in the CT6 is also a clunky box-type thing, totally unlike the near-elegant T-shape used in the Volt. This despite the fact that the guts of the two packs are similar. Both have 192 li-ion cells and weigh almost the same, but GM tuned the CT6 pack for acceleration instead of range, the way it did with the Volt's pack. Still, the main reason the packs are different is because the CT6 is a rear-wheel drive vehicle, and the tunnel that the Volt's pack uses is occupied by the driveshaft. Despite the highly touted second-gen Chevy Volt going on sale last year, GM still has the capacity to build battery packs for the old, first-gen model. This is because the company is legally required to be able to provide replacement packs for warrantied vehicles (for up to 10 years), and the second-gen packs don't fit into the first-gen vehicles.

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.

2014 Cadillac CTS images leak from somewhere

The redesigned 2014 Cadillac CTS will be unveiled this Tuesday on the eve of the New York Auto Show, but as often happens, some images of the car have leaked onto the web a few days early. Previously, the only information we had on the 2014 CTS concerned the all-new twin-turbo V6 engine that will be found underhood, rated at 420 horsepower and 430 pound-feet of torque.
While none show the new car in its entirety, the images do show much of the front end, particularly the headlights that feature vertical bars of LEDs that start down low as foglights and continue up to the top of the front fenders. They're similar to the lighting design first shown on the XTS and ATS, except the lower portions are much taller.
There are also views of the rear end and one of the taillights, as well as an interior shot of the front passenger door. The latter image has us most intrigued, as it shows some very high end materials being used in the new CTS interior. The low-gloss wood trim, in particular, looks very premium.
