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:

2021 Cadillac Escalade ESV will debut at the New York Auto Show

LOS ANGELES, California — Cadillac pulled the wraps off its 2021 Escalade today at an event in Los Angeles, and we were there to see it all play out live and in living color. But while we have some specifications for the long-wheelbase ESV version, that model wasn't on display. According to the automaker, the next-generation Escalade ESV will get a formal debut at the 2020 New York Auto Show in April. The 2021 Cadillac Escalade ESV will boast a wheelbase of 134.1 inches and an overall length of 226.9 inches, making it 15.9 inches longer than the standard Escalade and 5 inches longer than the similarly extended Lincoln Navigator L. That extra length translates into 1.7 additional inches of third-row legroom and 17.4 more cubic feet of cargo space behind the third row over the standard Escalade. We expect the ESV will get the same two powertrain options as other Escalade models. The standard 6.2-liter V8 puts out 420 horsepower and 460 pound-feet of torque. An optional 3.0-liter diesel-fueled inline-six will offer 277 hp and 460 lb-ft while delivering improved fuel efficiency over its gasoline-powered sibling. Both engines will be mated with 10-speed automatic transmissions. The 2021 Escalade will go on sale in late 2020. We're not yet sure if the extended ESV will come at the same time or be added later, but we ought to know more by its debut in April. Related Video:

C7 Corvette won't spawn new Cadillac XLR [w/video]

Between the new 2014 Chevy Corvette Stingray and the even newer Cadillac Elmiraj Concept shown off at Pebble Beach, we were already expecting some sort of chatter of a Cadillac XLR redux. During an in-depth C7 Corvette discussion with Tadge Juechter, the car's chief engineer, Fox News asked if a Corvette-based, Bowling Green-built Cadillac will be built off the C7. Non-spoiler alert: the answer is no.
Juechter says that General Motors has "no intent" on transforming this car into a Cadillac product since the C7 has been optimized for the Corvette buyer, a consumer that's generally a different sort of person than a Cadillac intender who might also be cross-shopping a Mercedes-Benz SL-Class or BMW 6 Series.
While we're not ready to write off a future XLR altogether, we assume that the Corvette Cadillac experiment is most likely never going to happen again. The interview with Juechter is posted below, but the XLR discussion comes in at the 9:00 mark.
