Well tesla s is about 700hp or new rivian they plenty power and no much sound not that whine at least. And Block said he cant feel car because camt heat tires or engine just constant whine so i guess it was hard for him to adapt that fast to new way of feeling car from petrol way.
It depends on the design of both the car and the motor(s). Some cars only have 1 motor per axle, some have 2. With 2 motors per axle, there isn't that much need for the higher RPM to get the power and torque needed. So if a vehicle has 1 motor each wheel, there is much less RPM needed.
Motor noise comes from the design of the motor itself. The noise of a healthy electric motor primarily comes from the
deformation/vibration of the stator.
The more vibration, the higher the tendency of the pitch/whine of the motor. Some electric cars use structurally rigid stators like the
Nissan Leaf, hence the relatively quiet performance even at load at its top speed of 151 kph and during 0-100 at 6.1 sec. We don't have the official RPM details of
Tesla Model S. Some say it tops out at 14,000 RPM. If the Tesla has such RPMs, then they may have used a more structurally-rigid motor/stator coil to make the operation as quiet as possible. As luxury cars, the cabin is also very well-insulated. Some project motors can go up to 22,000 RPM in drag applications (Some say they can go higher).
Formula E, with the 200 KW motor tops out at 17,500 RPM at 280 kph.
We don't have that much details on the
Mach E, as well, even motor RPM. If it is one of those overdriven 22,000 RPM engines, sometimes even the most rigid motor designs will just whine due to too much wobbling of the stator.
Regarding Ken Blocks complaint of not hearing the tyres, it's Ford's or the tuner's responsibility to insulate the cabin or seal the air gap better between the motor and the atmosphere. They may have left little or no insulation probably because they want the numbers.
I can imagine him requiring to hear the sound of the tyres because he is an exhibitionist. He needs to hear the tyres. I know he does rallycross but it's different from rallying where, during training, one has to be able to handle the vehicle only with visual cues and feel. During my time in OZ, the training was top notch. We even had to wear ear plugs/muffs so we wouldn't have to hear the engine. Not sure how the training is there now but many of people I knew were able to go to higher levels internationally. I was too young that time then
love happened.
