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:

Cadillac Super Cruise needs subscription after free trial period

Not long ago, Motor Trend broke the news that Cadillac's Super Cruise is only free for the first three years, after which the Level 2 autonomy system moves to subscription pricing. MT's report came on the eve of 2018-model-year Cadillac CT6 buyers being asked whether they wished to retain access to their Super Cruise. A few days after that report, Cadillac said it would give those first-year buyers of the technology — "the helpful adopters" — another free year, so they'll need to make a decision in August 2021 along with the 2019MY CT6 buyers. After a bit of digging by other outlets, it seems Motor Trend broke the Super Cruise news primarily to members of the media (including us); the details in the report have been communicated to customers in fine print in at least two places. First, let's clarify that the subscription is for OnStar, not Super Cruise only. Cadillac has made clear since the beginning that the tech needs an active OnStar plan, a Wi-Fi Hotspot, a working electrical system, cell reception, and a GPS signal to work. Knowing that, and knowing OnStar is only free for one month on new vehicles — GM shortened the free trial last year from three or six months — before requiring a subscription, might have encouraged someone to ask the question before now (we didn't...). In response to Jonathan Gitlin at Ars Technica asking Twitter about who knew, Bozi Tatarevic responded, "It might not have been released in the press materials but I remember reading about it in the order guide documents for the CT6 and noting that it was tied to OnStar and would eventually require a plan that started at like $25 per month." And Tatarevic pointed to this snippet in The Philadelphia Inquirer review of the CT6 from 2018: "The Super Cruise feature is part of OnStar and is free for three years. OnStar advertises subscriptions from $24.99 to $59.99 a month." If Super Cruise is only free as long as OnStar is free, then new car buyers now will get the tech for one month. Owners who cancel OnStar or choose a plan that doesn't include Super Cruise will still benefit from adaptive cruise control and lane-centering.   The automaker hasn't said what Super Cruise pricing will be, but the OnStar site apparently reveals the answer. There are six plans listed on the Compare Plans page, but two are combinations of other plans.
