The new BMW i5 M60 xDrive is in the final phase of its development – part of this chapter is driver testing under challenging conditions. Making an appearance on the list of locations is the icy test site in Arjeplog, Sweden. Not only does the all-electric powertrain have to prove itself here, but the chassis and control systems of the BMW M GmbH performance model will also receive their final tuning near the Arctic Circle. BMW M engineers Michael Tobias, Functional Design and Integration Powertrain, and Daniel Mögele, Functional Design and Integration Driving Dynamics are part of the development team. We met with them for an interview.
The goal with the BMW i5 M60 xDrive was to achieve a range from absolute sovereignty and comfort to the ultimate expression of the dynamics that M is known for combined with the directness of the powertrain. And we have succeeded in doing just that with the new, all-electric powertrain.
Daniel Mögele: The electric powertrain offers even more possibilities in terms of driving dynamics on loose surfaces such as snow, ice, or wet surfaces. The high dynamics of the driveline combined with the actuator-related wheel slip limitation, abbreviated ARB, is even superior to vehicles with combustion engines. This results in perfect traction, as the system keeps all four wheels in the optimum grip range. Driving performance in the BMW i5 is correspondingly better on surfaces with low friction values than in vehicles with a comparably powerful combustion engine powertrain. This is particularly evident when it is driven at the limit. In terms of precision, it's a completely different world with an electric vehicle.
The BMW i5 M60 xDrive takes full advantage of the driving dynamics benefits offered by the vehicle concept.
Presidents don't run, but they can - that sums up the character of the BMW i5 M60 quite well.
