Winter testing of BMW i7 to prove out suspension and drive systems

LinkedIn +

Engineers from BMW are currently evaluating the i7’s driving dynamics at the car maker’s winter site in Arjeplog, Sweden. Testing of the luxury BEV saloon on the area’s snow-clad roads and frozen surfaces will encompass fine-tuning of the performance of all suspension and drive systems, including the steering, braking and vehicle stability systems. In particular, the springs, dampers and various regulating technologies are undergoing assessments to make those final tweaks that will ensure maximum driver feedback and enjoyment across the various drive modes.

According to the German giant, the tough winter conditions, specifically Lapland’s frozen lakes with their low road friction coefficient, enable meticulous development of the steering, dynamic stability control system and accurately regulated interaction between friction brake and deceleration by means of energy recuperation.

Testing of the i7’s all-electric drive system will cover the electric drive, high-voltage battery, power electronics and charging technology, which all originate from the fifth generation of BMW eDrive technology, as found in the iX. Above all, the motor, battery and temperature control system of the i7 must prove their performance and durability in the extreme sub-zero temperatures of northern Sweden.
