Through even more efficiency! – Although in the world of combustion engines it was actually said: “There is no substitute for displacement except … even more displacement”. This is because displacement usually goes hand in hand with high torque available over a wide speed range. But with an electric motor and especially with the TWIKE 5 drive, torque is available. More than enough.
The challenge lies more in efficiency. The TWIKE 5 is already good in this respect thanks to its low weight and optimally reduced size. So why make it even better? Because it makes sense. And because it is still possible in the current development phase. But also because the eventual switch to an equally robust but smaller-capacity battery cell means that we don’t want to jeopardize the targeted WLTP range of 400 km. A short vehicle length does not generally offer the best conditions for this. However, an intensive simulation shows that a cd value of 0.24 can be achieved with minor modifications.
Although a further improvement to 0.21 requires more in-depth measures and, above all, more intensive simulation work, it can reduce the WLTP consumption from an already impressive 7 to 6.5 kWh per 100 km of driving distance in the foreseeable future. The focus of development work is still on the body shell, the chassis components and the drive system. This gives us the opportunity to further optimize the exterior surfaces. And we would like to take this opportunity. Over the next few weeks, the source of each disruptive air vortex (magenta blue in the illustration above) will be successively traced from the front spoiler to the trailing edge of the diffuser and the resistance reduced once again.
We look forward to your questions and comments in the comments.
Let’s TWIKE!
