General Motors will offer a choice of different sized battery packs on all future electric vehicles that utilize its Ultium battery design.
During a presentation of the new Ultium platform to Canadian media in July, GM Lead Engineer for New High-Voltage Battery Packs, Andy Oury, said GM’s “launch plan has multiple size battery packs for each vehicle entry.” That likely means future GM EVs will be offered with a standard-range battery pack and a long-range battery pack, similar to Tesla vehicles and other rival EVs.
We already know that the upcoming GMC Hummer EV pickup and SUV models will offer more than one battery pack size. While GM has not confirmed how large the GMC Hummer EV Edition 1 battery pack is, online sleuths have deduced the pack likely has a usable capacity of roughly 200 kWh based on its 350-mile estimated range. Since the Edition 1 is the most powerful and most-equipped version of the GMC Hummer EV Pickup, it seems logical the estimated 200 kWh battery will serve as the larger option in the lineup.
We can also expect the Cadillac Lyriq to be offered with a battery pack that is either bigger or smaller in size than the 100.4 kWh unit found in the 325-horsepower, rear-wheel-drive model that debuted this year. A performance all-wheel-drive version of the Cadillac Lyriq is expected to launch sometime in the near future, which could feature a battery pack with a different capacity. The RWD version of the Cadillac Lyriq, for reference, has an estimated range of over 300 miles.
Battery packs for future GM vehicles will be produced by Ultium Cells LLC, a joint venture between the automaker and its battery manufacturing partner, LG Energy Solution. Ultium Cells is currently building two battery plants in North America to support the automaker’s upcoming EV onslaught, one of which is located in Lordstown, Ohio and the other in Spring Hill, Tennessee near its Spring Hill Assembly plant.
