Speed Limiter on Mini Cooper SE

No idea about coding but doubt it could do more than 165km/h

The i3 motor, 168bhp at a maximum of 11400rpm had a 150km/h limited top speed.
I calculated max speed based on 11400rpm, 9.665 gear ratio and 0.3498m wheel radius to 155.54 km/h

For the i3s BMW used the same motor (same part no.) but raised rpm limit to 12000rpm and limited top speed to 160km/h
Doing the same calculation as above I get 163.73 km/h

I have seen "performance tuning" packages for the i3 & i3s to 156/157 km/h & 165 km/h respectively which would correlate with the above.

Remember EV has only 1 gear and rated power is for the i3 is listed in the datasheet @ 4800rpm, these are NOT built for top speed runs (even before considering the draw on battery/overheating).

What is surprising is the 223km range in the photo above, 123km is closer to what I get. That must be pootling around town mileage.

165km/h is for the i3s which is on 19s so even lower top speed for the mini (mine is on 16s) combined with the smaller battery 32 vs. 42 kWh you can see why they set the limiter on 160 & 150km/h respectively.

You are gear limited which is why you can’t go quicker, ICE with same power will do 235 km/h but has 5/6/7/8/etc. gears, and yes the drivetrain is built for top speed meaning it is geared for 280+ but will happily sit at 235 (where it’s power limited) without overheating in a couple of minutes.

You have a 135kW motor in the mini combined with a 32kWhpower source which is designed for acceleration NOT top speed. If it was geared for top speed acceleration would be lower, and you would need a beefier motor/bearings/cables/thermal management system/etc.

A Tesla geared for top speed will have for example a 100kWh battery with a motor that spins at 18000 rpm, taycan has a 2 speed gearbox (different approach)

Travelling at high speed in an EV is very inefficient, same for high loads such as towing which is why the cars are designed for the specific range we mention, removing the limiter in eDME won’t magically bring your top speed to 235km/h, need to change gearing or overspeed the motor to go above 160ish
