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 finds a few more horsepower for ATS-V

We've rarely found cause to complain about a car getting more power, and guess what? That's not going to change here. After initially announcing that the new ATS-V would come to market with a Corvette-matching 455 horsepower, Cadillac has come back with an SAE-certified 464 horsepower. That, as Automobile points out, puts the high-performance ATS in spitting distance of the base Mercedes-Benz C63 AMG and its 469 hp. Anyone else feeling bad for owners of the 425-hp BMW M3? While the ATS-V is getting a bit more grunt, somehow, we doubt Cadillac will adjust its previously published performance figures. Expect 60 miles per hour to arrive in 3.9 seconds, with a top speed of 185 mph. As of this writing, a lucky Autoblog staffer is lapping the ATS-V around Circuit of the Americas in Austin as part of the sedan's big launch. So while we can't fill you in on its real-world performance just yet, expect a big update soon. Related Video:

Cadillac dropping trims, powertrains for 2020 CT6

First reported by CarsDirect and later confirmed with Cadillac, the CT6 order book will see some changes for 2020. The luxurious American sedan is losing trims and losing engines but gaining standard equipment. For the 2020 model year, Cadillac is distilling the CT6's seven different trims down to three: Luxury, Premium Luxury, and Platinum, all three of which have new standard features. The Luxury trim gets the Driver Awareness and Convenience Package. Premium Luxury benefits the most with Super Cruise, the Rear Seat Package, the Comfort and Tech Package, and the 34-speaker Bose Panaray Sound System. The Platinum gets new unique 20-inch wheels, and the V-Series (considered a different model) gets the Driver Assist Package. As we've previously reported, Cadillac will also be reducing the number of available engine options. The 2.0-liter turbo engine has already been dropped, and the 3.0-liter twin-turbo V6 is next. For 2020, the CT6 will only offer the choice of the 3.6-liter V6 on Luxury and Premium Luxury trims and the 4.2-liter, twin-turbocharged "Blackwing" V8. All models and trims come standard with all-wheel drive. Cadillac has also confirmed pricing to Autoblog. Including destination charges, the Luxury model would start at $59,990, the Premium Luxury would start at $75,490, the Platinum will start at $97,490, and the V-Series will start at $95,890. Overall, prices go up due to the removal of the 2.0-liter model and more standard equipment, though the cheapest model on the configurator right now is $63,590. On the high end, the 2019 CT6 Platinum with the twin-turbocharged engine starts at $87,790. We'll update when this all goes official.
