In response to the distrubtion of the autosector by Tesla, GM unveiled 10 EVs on the 4th of March 2020 in Warren, Michigan. The GM EV strategy, which to was more about be compliant, is underpined by it’s partnership with LG Chem to produce enough batteries for 1 million EVs per year by 2025. To achieve its bold new plan GM will invest $20 billion by 2025 and release 20 new EVs by 2023. GM hopes on the extension of the EV tax credit to support its EV strategy.


The GM / LG Chem partnership is establishing a 30 gigawatt hour battery plant in Lordstown, Ohio. The $2.4 billion plant will produce 250 million large pouch format battery cells which is named Ulthium cells. The Ulthium cells is a new NCMA chemistry which uses 70% less cobalt by employing a new aluminium cathode. The Ulthium battery system is modular and can be configured in battery packs from 50kWh to 200kWh which can deliver ranges up to 400 miles. The Ulthium pouches can be stacked  in various ways, allowing for more battery pack shapes to meet various vehicle needs.


The battery system, which form part of GMs BEV3 EV platform, can either be 400 volt or 800 volt supporting 200kWh or 360kWh charging infrastructure respectively. Interestingly, GM announced that it only needs 19 combinations of battery and motor configurations as apposed to 550 engine and transmission configurations for it’s ICE fleet. The BEV3 drivetrain sports charging of 100 miles in 10 minutes and 0-60mph in 3 seconds.


The new NCMA battery chemistry is expected to drive cost of batteries below the $100 per kWh price tag, which is seen as the level needed for EVs to compete equally with combustion vehicles.


In terms of it’s EV line-up, GM unveiled cars across it’s Chevrolet, Cadillac, GMC and Buick marque brand’s. The EV onslaught commences with the release of the new refreshed Bolt in 2020, followed by the 3 inch longer Bolt EUV and GMC Hummer in 2021, and the Cadillac Lyriq in 2022. The Lyriq’s launch date is set for 8 April 2020 and that of the Hummer on 20 May 2020. 


In terms of autonomous driving, GM will equip 22 cars by 2023 with its Super Cruise semi-autonomous Level 2 driving technology, starting with the Bolt EUV as the first EV equipped with it.


GM is breaking from Tesla’s strategy of creating its own charging infrastructure, by rather going the partner route. GM partnered with Chargepoint and EVgo on its myChevrolet app. Qmerit will cover homecharing solutions and installations for GM

 

The line-up unveiled by GM on March 4 2020:


Cadillac - The Lyriq crossover, Celestiq hand-built flagship sedan, Cadillac SUV


Chevrolet - Lyriq sized crossover, 2020 Bolt and Bolt EUV


GMC - the Hummer and a short wheelbase version


Buick - one small and one mid-sized crossover
