Hmm ? ...something doesnt add up here ?
....can someone explain how a 70Nm motor ...or even 4 of them...fitted in wheels , can come anywhere near to the performance of a single GM Bolt motor at 400Nm driving through a 4:1 reduction to the wheels ?
.....and if they can , we will move on to the Tesla, with 1100Nm and a 9.7:1 drive ratio !:eek:
