    Cadillac Lyriq Technical Details

    This is the first GM vehicle to be unveiled that features the automaker's new Ultium battery system, which is part of a modular EV architecture. Thanks to advanced nickel-cobalt-manganese-aluminum chemistry and careful engineering, these assemblies use 70% less cobalt, a rare element that's difficult to source responsibly. They'll also have a whopping 90% less wiring than current GM battery designs.

    With a claimed capacity of around 100 kilowatt hours, the Lyriq should provide a driving range of at least 300 miles. The vehicle will be offered with either rear- or all-wheel drive. Expect a nearly 50:50 weight distribution for improved on-road manners, and according to Marty Hogan, the Lyriq's executive chief engineer, its center of gravity will be around 4 inches lower than a Cadillac XT5's. Serving double duty, Hogan also said the battery is "a structural element in the vehicle," enhancing stiffness and crash performance.

    Typical of modern electric cars, this amped-up SUV should deliver impressive performance. GM has not shared an official 0-60 mph number, but Hogan noted, "This vehicle will not be a disappointment relative to where our competitors are at." A Tesla Model X in Performance trim, for instance, offers 305 miles of range and can hit 60 mph in an organ-bruising 2.6 seconds. It's not unreasonable to expect similar giddy-up from this Cadillac.

    Once its driving range is depleted, the Lyriq's battery pack can be replenished quickly. The vehicle will support Level 2 charging at a rate of 19 kW and even DC fast charging at up to 150 kW.

    The Lyriq will also feature a new dual-pane head-up display with augmented reality. Comprised of two planes, the nearer one shows things like speed and direction, while the farther pane can project alerts and navigation signals onto the windshield.

    Naturally, the latest version of GM's acclaimed Super Cruise will be offered on the Lyriq. In certain situations, and with careful monitoring, it allows hands-free driving on more than 200,000 miles of roadway in North America. As in the upcoming 2021 Cadillac Escalade, it will also support automatic lane-change capability.

    It would seem to me that this Cadillac will be a technical tour de force. If they can do a proper interior...

    Is this the link? Never mind, I can't post it either, I get "Your post contains inappropriate content"

    So, for non-technical people like me, what does 19Kw level 2 charging translate to in time? Is that 20 minutes for 80%?

    When they say over 300 miles, I would presume they will hold that close till its time to sell the vehicle. This whole thing is too early. Perhaps someone else will rush something to market to be 'first' with all these features

    If the capacity of 100 kw hrs gives you 300 miles, I would estimate that an hour's charging at 19 kw would give 1/5 of that, or 60 miles in an hour of charging.

    300 miles is over 4 hours of driving... at some point one has to pee

    DC fast charging up to 150kW is laughable. Coming to market in two years and it'll be four years behind.

    Yes,but you'll have to stretch that pee out to 20-30 mins while your BEV recharges..I guess people by then will have managed to grow two bladders.

    At 150kW you'll be waiting about 45-55 minutes depending on the charge profiles for the car. Even then it'll get ya to 80 percent. That top 20 percent is difficult on a DC fast charger.

    Tesla is already working on 400kW fast charging. GM is stuck working with 3rd party vendors for charging. It's gonna be iffy.

    How long does it take for that, just a few minutes at most - not enough time to do the EV connect/disconnect let alone any meaningful charging.

    The bolt charges to 80 percent in 50 min now. Your timetable is off. Also, the dual motor setup is probably the 100kw battery pack which will offer the 400 plus mile range setup. The single motor is the one that’s 300 plus mile range which would be on the base version. Without full details I think that’s where the misinformation is.

    How is my time estimate of 45-55 minutes off when you said it charges to 80 percent in 50 minutes??

    A Model 3 can go from 5 percent to 90 percent in 30ish minutes but that's the wrong way to supercharge anyway. If you Supercharge hop you can recharge enough to make to 150 miles in about 15 minutes. That's why 150kW is going to be brutally slow because most of the fast charging will happen under 100kW.

    Re: Cadillac Lyriq Technical Details

    If EVs become very popular, I wonder if there will be long lines to charge at supercharging stations, if each car is taking a half hour or more to charge. I also wonder about the damage that could be done to your batteries from repeatedly super charging like you would do on a long trip.
