Deliver High Performance with ProteanDrive
The formula: 2 x eAxle + 4 x ProteanDrive = 0-100km/hr in 1.9 secs
As with range, many vehicle manufacturers like to offer performance variants of their products because they improve margins, expand market reach and gain footfall in the dealerships.
Increasing performance is challenging due to packaging constraints, unless you use the space within the wheels.
We have modelled that by adding 2 ProteanDrive in-wheel motors and a 100kWh battery, you could get to 0-100km/hr in 2.5 seconds. To put this into context F1 cars accelerate from 0-100kph in around 2.6 seconds. If you’re still looking for more, then there is the option to use the available space in the wheels on the other axle to add an additional 4,400Nm to the vehicle, making an incredible total of 17,600Nm, reducing the theoretical 0 to 100kph time to a class leading 1.9 seconds, again without impacting packaging. Naturally with this level of performance battery and traction limitations need to be considered, and, just like extreme modes on other cars, users may need to accept some limitations when accessing this level of performance.
Note: Our study used a well documented platform, available on the market, in order to demonstrated the possibilities that ProteanDrive offers. We have also calculated that though application of the IWMs does not increase vehicle weight to the same extent as an eAxle, there is some increase and this will have a small but measurable impact on the range. We have calculated this at 5km. In this scenario, the upgrade would not need any major structural modification of the platform and the required engineering efforts would also be well justified with the benefits delivered.
