Not really bashing, just pointing out that EV's aren't like ICE cars. You cannot just stuff a more powerfull motor in the car and get more power. The battery dictates the power. Basic EV fundementals.
The vehicle doesn't have to be heavier, but the cells that make up a small pack, with a high power density, cost quite a bit of money. If an automaker would produce such a car, it would be expensive, and most likely not sell because of the limited range from the small pack. It could be relatively light, which equals better performance, but not range.
A car with a lower power density pack, using cheaper cells can also have performance, but the pack needs to be bigger(Tesla), which means more weight and range, and most likely cost. The cells are cheaper, but there is more of them, therefore it costs close to the same as the example of the light car with the high power density cells above.
As I said, I understand electric (and ICE) vehicles quite well. The battery does NOT dictate the power, the whole system has to work together, just like on an ICE vehicle. On an ICE vehicle, you can't just stuff a more powerful engine in...there's axles, clutches, transmissions, fuel system, exhaust system, intake system, cooling system, etc. that all are sized for the engine power. The same goes for an EV.
If you want to get technical about EVs, the power inverter, cables, connectors, fuses, contactors, cooling system, heating system, transmission, axles, etc. all have to be sized as part of a system as well as the battery. Are you saying that GM has designed a motor that is more powerful than the system is capable of supporting? If so, do you have data to support that? I don't think GM would have spent money making a motor capable of 100 kW and then making the rest of the system undersized, but I'm listening if you know something that I don't.
