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:

Super Cruise will feature in 22 GM nameplates by 2023

Super Cruise, the semi-autonomous hands-free driving technology that first appeared on the 2018 Cadillac CT6, was always intended to broaden out to more GM models, especially now that CT6 production has ended, but now we have specific numbers. Automotive News reports that GM will have it on 22 nameplates by 2023. GM President Mark Reuss spilled the beans to investors at the company’s Capital Markets Day presentation, saying that Super Cruise will start appearing in brands beyond Cadillac in 2021. GM just last week announced the first big update for its driver-assist technology late last month, saying it would be coming to the 2021 CT5, CT4 and Escalade full-size SUV, all of which should debut later this year. Next year weÂ’ll see it offered as an option on seven more nameplates, then a dozen more in 2022 and 2023, Reuss said. The next generation of the technology will come with a new feature called “Lane Change on Demand,” which will allow the driver to activate or tap the turn signal and the car to do a hands-free lane change if itÂ’s safe to do so, and so long as the driver monitor system can tell the driver is paying attention. ItÂ’s also said to feature improved performance and hands-free dynamics, a better user interface and software tweaks, among other upgrades. Super Cruise uses a camera and infrared light to detect whether the driver is paying attention, plus radar, cameras and lidar mapping to center the vehicle in a highway lane and drive in hands-free mode in optimal scenarios. ThereÂ’s no immediate word on whether the upcoming next-generation version will also come with an expanded network of compatible highways beyond the 200,000 miles where the technology is currently capable of being deployed. Autoblog named Super Cruise the 2019 Technology of the Year winner. Related Video:     Cadillac GM Emerging Technologies

Junkyard Gem: 1983 Cadillac Cimarron

Ah, the Cadillac Cimarron. Conceived during a time when oil prices were zooming upward and smallish luxury imports such as the Datsun 810 and BMW 320i were stealing Detroit's customers, the idea of a fuel-efficient compact Cadillac made sense. Unfortunately for GM, the Cimarron was an image-tarnishing disaster. Here's a fairly well-preserved '83 that I spotted in a Phoenix self-service wrecking yard. In the words of Pulitzer-winning Dan Neil in his 50 Worst Cars of All Time: "Everything that was wrong, venal, lazy and mendacious about GM in the 1980s was crystallized in this flagrant insult to the good name and fine customers of Cadillac." The Cimarron was a Chevrolet Cavalier with a bit of added bling and a fatter price tag. The Chevrolet Nova-based Cadillac Seville had sold pretty well during the late 1970s, so there was precedent for a small, Chevy-based Cadillac. The hood latch mechanism was broken (of course), so I couldn't shoot any photos of this car's 2.0-liter pushrod four-cylinder engine, rated at 86 horsepower. Here's a GM-produced documentary touting the futuristic design of the '83 Cimarron. The Cimarron Dream.
