Based on drag and motor output (50kw) they would reach equilibrium with rolling and air resistance at rather extreme speeds of 217 mph. The motors have plenty of power (50kw each) but cant switch fast enough. If they wanted to Elaphe could probably solve this but I don’t think it would be very useful beyond just another high marque spec. Technically the lower battery size vehicles could max out even higher but not by much (about 2 mph assuming the smaller battery can output at the max draw of the motors). The skin cooling could potentially also be unable to keep up with this for any sustained period.
Ya while I stand by my calculations related to range and the physics it looks like extrapolating top speed by powertrain kW is not an accurate approach. Applying the same logic to a model s plaid ends up with insane numbers – almost 300mph. I think the flaw is that any EV motor will drop off in power and efficiency at higher speed.
