The BMW i3s is not only a more powerful version of the BMW i3s but it was also fitted with a few new tech including the new traction control system and help improve the overall drive of the BMW i3s.
The system helps improve the drive by allowing the vehicle to pull away from a standstill faster thanks to the use of instantaneous torque. The use of regenerative braking also helps improve the stability of the vehicle when accelerating out of corners. People that did try out the BMW i3s reported that the upgrade is noticeable.
Well, the good news is BMW is looking to offer the same kind of upgrades to their BMW and Mini models in the near future. While the system currently makes use of the electric motor, BMW did say that the shorter cycles of the system show promise for internal combustion vehicles as well.
