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 will expand its range of high-performance Blackwing models

Cadillac proved the American sport sedan isn't dead when it introduced the Blackwing variants of the CT4-V and the CT5-V (pictured) in February 2021. Launched to denote a short-lived V8 engine, the nameplate will appear on other go-fast members of the company's range in the coming years, but there's at least one model it will steer clear of. "Blackwing is reserved for really the pinnacle, the purest expression of performance and track capability, and that's what it's going to stand for going forward. [The CT4-V Blackwing and CT5-V Blackwing] won’t be the last Blackwing cars that we do, but you wonÂ’t see one on every vehicle. ItÂ’s not appropriate. I couldnÂ’t imagine doing an Escalade-V Blackwing," said Cadillac engineering boss Tony Roma in an interview with enthusiast site GM Authority. His comments are reassuring, because they confirm that Cadillac won't water down the Blackwing badge by putting it on sporty-looking models that are more show than go. What's next remains up in the air. The CT4 and the CT5 are Cadillac's only sedans as of writing, so the next Blackwing-badged model will either be an electric car, a crossover, or both. Regardless, it should arrive as a truly track-capable hot rod developed for hardcore enthusiasts. For others, Roma also suggested more V-badged cars are in the pipeline, though he stopped short of listing the models the emblem will appear on. Demand for quick crossovers is growing steadily in America, so it's not difficult to imagine an XT4-V, for example. And, an unverified report published in February 2021 claims the Escalade's 6.2-liter V8 will soon receive a 200-horsepower bump thanks to a factory-backed, dealer-installed supercharger. If the rumor is accurate, the 600-plus-horse Escalade could be the V-branded model that Roma alluded to in the interview. "The V-Series lineup has expanded," he said. "You're going to see more of that in the future. We're going to do more V-Series. It's important to our brand, and you'll see it on other products." Related video:

Cadillac imagines the future of luxury transportation with a drone and a pod

Besides more screens and electric cars, GM and Cadillac made sure to pay tribute to the other darlings of the tech industry: autonomous cars and drones. Both concepts take familiar ideas but add a touch of Cadillac flavor. And don't expect either of them to show up in reality anytime soon. The most fanciful of the two is the Cadillac VTOL concept, which stands for vertical takeoff and landing. It's a fully autonomous drone meant for shuttling people, likely wealthy executives, from rooftop to rooftop in busy cities. It's a single-occupant aircraft with a 90-kWh battery pack and is fully autonomous. It has four sets of two rotors that propel the drone to a top speed of 56 mph. The exterior is unique in having the front and rear sets of rotors at different heights, whereas most seem to have the cabin hanging from the rotors. You can spot some Cadillac cues in the beveled, angled edges. The other concept is the Personal Autonomous Vehicle or PAV. It's a fairly generic-looking autonomous pod with a pastiche of Cadillac design cues such as slim lights and angular trimmings. Cadillac says it's meant to be a social space, hence the wraparound bench seats in the cabin. Cadillac doesn't seem to have forgotten personal comfort, though, as you can spot a single-person recliner. Comfort is key, and Cadillac says the PAV would have biometric sensors to read the passengers and adjust the climate control, humidity, lighting and scents to make the the environment as pleasant as possible. Passengers will have control of vehicle functions via voice and gestures. At the end of theses vehicles' reveals, Cadillac teased more far-flung concepts coming soon. One of them will be a two-seat vehicle and mentioned that it would be for "you and someone very special" for more "intimate" trips. Related Video:
