The purpose of this second round of testing in Sweden was to fine-tune all powertrain and chassis control systems. Thanks to their low-grip surfaces, the test areas sited on frozen lakes around Arjeplog were particularly well suited for delicately adjusting the drive torque control system in the BMW i5 under precisely reproducible conditions. In the new BMW i5, the DSC (Dynamic Stability Control) system, the near-actuator wheel slip limitation function and the drive torque control system are interlinked so that they can interact and complement each other flexibly in any driving situation. As a result, the all-electric sedan performs at least as proficiently as any conventionally powered model on ice and snow.

The integrated application of all powertrain and chassis systems underpins the outstanding handling abilities displayed by the BMW i5 in winter testing. The more challenging the conditions, the more impressive were the speed and precision of the control systems in the fully electric version of the new BMW 5 Series Sedan. The BMW i5 serves up a harmonious blend of optimum traction when pulling away and supreme driving stability when cornering or braking, which is unique in the competitive environment.
