The Bavarians really stand behind their own and, to prove that Ludwig Willisch’s claims that the i3 is the most eco-friendly car produced in the world right now is correct, the BMW Group decided to post some videos of the production process.

Amongst them, I found one that’s particularly interesting. It’s about the production process of the much-praised transmission used on the new EV. After hearing so much about the one-pedal driving the Munich-based company is marketing so much, seeing exactly what’s inside that ‘box’ became a must for me.

The whole process looks extremely simple: press-fitting the bearings and the joining shafts, teeth combing, joining the wheel set inside the housing, applying sealant (by a robot), bolting the lid and sealing the whole thing. Doesn’t sound that complicated, does it? Furthermore, it seems like it was done in under 5 minutes, making the process seem like a walk in the park. Check it out!
