I'm loving the car, but the acceleration is... weird.
If the car is at standstill and I put my foot down, the acceleration gradually ramps up until about 50km/h, where it seems to reach its peak. However, if I'm rolling along at 15km/h and put my foot down, it feels much more instantaneous, which is what I expected the acceleration to feel like on an EV.
So, why is there a difference? Why does the acceleration have a ramp-up when starting from standstill? Is it to prevent wheelslip? To reduce wear and tear? And how exactly is the ramp-up programmed? Is it designed to take a certain amount of time to reach maximum power, or is the available power determined by the current speed?
I'd appreciate any information on this, as Google has not been very useful.
Be wary of using a "butt-dynomometer" to determine acceleration rates.
There is a slight lull when accelerating from a dead-stop. Imho this (initial slew rate) is done to protect the drivetrain.
