Formula E Berlin

Actually this post comes a little late as the event is already over
On last years e-cannonball we won tickets to Formula E in Berlin.
I was super amazed when I learned that they complete 41 laps at full race speed with just 40 kWh. I then thought one lap was just 1 km as it seemed quite short but it was 2.3 km or 96 km total! (https://www.fiaformulae.com/de/calendar/berlin)
So under race speed they just consume 400 Wh/km! (equivalent to 5l/100 km or 47 mpg on petrol) How is that even possible? Well it turns out while they "just" output 350 kW from the rear tires when accelerating (the cars are 850 kg, go figure) they use another machine on the front axle to regen at 600 kW. Wow. Not sure how much friction braking is still involved there.
Overall an amazing weekend and great company. I met Mustang Mathieu there and we will meet again in two weeks to fix my battery cooling and his CCS.
