#3One electric motor per wheel gives the possibility for some really awesome torque vectoring. I could see a machine learning model being used to figure out the torque to apply to each wheel given the feature inputs of turn angle, lateral g, suspension height, tire temp, road temp, humidity, etc.

#4Why does this site have Baidu ads? It IS an ad.
"Each car costs approximately $1.2 million to build."

With fewer environmenal variables this is already done, to a degree, for locomotive-wheel traction motors. For example pulsing the torque in frequency and amplitude to manage wheel-slip on wet rails.

#6So, $1.2m and still lags behind the model s for 0-60mph by a wide margin?

Model S took way more than 6 Million dollars for the design.

I'm pretty sure Model S can't complete even half of the Nordschliefe without going into limp mode, so the comparison is not really fair.

Or you could just solve it analytically, making validation easier.

0.2s is a wide margin?
