Cadillac CT6 PHEV battery shape a big departure for GM's plug-in hybrid tech

Anyone with any familiarity with the electric powertrain details for the two General Motors plug-in hybrids will have noticed that the information we have about the newly announced Cadillac CT6 plug-in hybrid has a lot of numbers in common with the Chevy Volt and the Cadillac ELR, like the 18.4-kWh lithium-ion battery pack and an expected all-electric range of 37 miles. We also noticed that the announcement calls the plug-in CT6 hybrid an actual plug-in hybrid and not an "extended range electric vehicle (EREV)," which is what GM calls the Volt and the ELR. This, of course, means we needed to ask GM some questions. Donny Nordlicht from Cadillac communications told AutoblogGreen that while the Volt and CT6 batteries are both 18.4-kWh, the shape is completely different. In the Volt/ELR, the battery is T-shaped (see it here). The CT6 has four seats, with a tunnel running between the two in the rear, as you can see here, but the battery in the CT6 PHEV is "a cube-shaped pack, which is between rear seats and the trunk," Nordlicht said. "There is no pass through." GM has not yet released any technical schematics about this pack, but Nordlicht said that, "The CT6's advanced mixed-material platform was designed to accommodate the PHEV system by design so that it minimally intrudes on the cabin space." It also means that the CT6 can be ordered as an optional PHEV, while the Volt and ELR were purpose-built plug-ins. GM is also distinguishing between the EREV and PHEV powertrains in its vehicles from this point forward. "We are not discarding the EREV language," Nordlicht said. "The CT6 utilizes a two-motor system mated to a 2.0T 4-cylinder engine, which is an all-new system to Cadillac." We assume that the PHEV packs will use li-ion cells from LG Chem, just like the EREVs do, but Nordlicht did not answer our question on that point. As for other details about the CT6 PHEV – like production, full dimension, and pricing – we will just have to wait until closer to when the vehicle launches for those. Related Video:

Mary Barra thinks GM is a leader in autonomous tech

Saying General Motors is "among the leaders" in autonomous vehicle technology, CEO Mary Barra rapped about her company's driverless work in an interview with USA Today. Barra covered a number of topics, including well-known efforts, like Cadillac's upcoming Super Cruise technology, as well as hinting at "a lot of efforts that are confidential." "Things are moving quickly in autonomous [cars] because there's so many different pathways and the standards aren't even set. A lot of people can claim leads because people are making advancements in different areas," Barra said. "Next year we're going to have Super Cruise on one of our Cadillacs. On highways you'll be able to take your hands off the wheel and feet off the pedals – with a very creative way to make sure the driver is alert and involved in the driving process." As for those "confidential" efforts, feel free to speculate. GM has recently confirmed that it'd be running autonomous Volts at its Warren, MI tech center, which certainly indicates that the company is playing with much more than Super Cruise. GM will need to continue to embrace autonomous driving, owing to both traditional competitors like Toyota, as well as non-traditional opposition, like Google and Apple. Speaking of its competition from Silicon Valley, Barra was asked about two of the region's biggest names – Apple's Tim Cook and Tesla boss Elon Musk. "I have tremendous respect for Tim Cook, and I don't really think he needs advice from me," Barra told USA Today with a laugh. And when asked about Apple's future as a "viable competitor," she said, "I have no insights other than what I read in the papers. But it would be foolish for me not to assume that they're going to." As for Mr. Musk's openness about future products and how it contrasts with GM's relatively closed attitude, Barra also gave a chuckle. "I'm sure you would like me to say yes. I think we're fundamentally different. Look at our volume and look at the segments where we compete. His product line – his two products – his scale, it's completely different." The rest of Barra's interview is certainly worth a read, and includes talk about the Volkswagen diesel scandal, GM's changed relationship with the National Highway Traffic Safety Administration, and Uber.

Ford C-Max spot aimed squarely at Cadillac ELR 'Poolside' hubris [UPDATE]

If we had tried to predict the first video response to the controversial Poolside video for the Cadillac ELR, we would not have thought it would center on compost. But, hey, it's always nice to be reminded that the real world is sometimes better than fiction. Instead of the chic swagger of 'Poolside,' 'Anything Is Possible' is all about getting dirty. The new short in question is called Upside: Anything Is Possible and it promotes two things: Detroit Dirt and the Ford C-Max Energi. As in the ELR ad, Ford's plug-in C-Max only makes an appearance at the tail end of the spot, but instead of the chic swagger of Poolside, Anything Is Possible is all about getting dirty. The ad stars Pashon Murray, co-founder of Detroit Dirt, which takes natural waste from around Detroit, composts it into soil and then spreads that around "forgotten parcels" of Detroit to create urban farms. Detroit Dirt gets its bio-waste from a lot of sources, including the Detroit Zoological Society (all that herbivore manure has to go somewhere), Ford and General Motors, but this particular ad was the idea of Ford's PR agency, Team Detroit. It was a frenetic shoot, filmed with an LA-based director right after a big winter storm blew through Detroit, and Murray couldn't be happier with the result. "This was Ford Motor Company pushing my story, letting me tell the story that I believe in," Murray tells AutoblogGreen. "I get to help push this car and I get to tell my story." She says that the Team Detroit and Ford had to agree on the message, "from my understanding, [YouTube] is where they wanted to start, not where they wanted to finish." The ad is already getting a positive response on Twitter, so we won't be surprised if it shows up in more places soon. "It's not saying Ford is better than GM. It's telling the story of a black woman who's working hard in Detroit." As Detroit Dirt has off-screen support from both GM and Ford, it's unsurprising to hear Murray say that the video "is not a rivalry thing." She notes that the ad agency Team Detroit came to her and offered to tell the Detroit Dirt story using the framework of the GM ad. "It's a parody on this commercial, but it's not saying Ford is better than GM," she said. "It's telling the story of a black woman who's working hard in Detroit." What is that story? It's about urban farming, recovery and recycling. Murray tells us that for the last seven or eight years, she's been dedicated to sustainability.
