 The first one goes to Erhan Jojowsky across the line, celebration style! Hey guys, Romain here. We are just ahead of the second round of the Formula E Accelerate Championship where we've got Risto Kappet and Erhan Jojowsky racing. And today I'm going to speak to you about the energy management. Formula E is an electric racing car, so in the race you need to manage your battery not to run out before the end. So this is done by Lifton Coast. Lifton Coast is basically lifting the throttle before the straight line is over, letting the car roll, and then eventually when you get to the braking zone you hit the brake. But instead of stalking, best of going on track. Okay, so here we are on the start-finish line and let's go! Full on throttle, getting into turn one, here normal braking, lift the throttle, straight away on the brake. Mr. Biddy, it begs, no big deal. Now we're going into the longest straight of the circuit. So what I'm going to do is when I reach the 200 meters board, right now I'm going to lift the throttle, let the car roll and eventually now hit the brake. That allows me to save a fair bit of energy through all the straights and to manage it. Obviously when you're fighting other drivers it's not something you can do, so really during the race the challenge here is to decide where you're going to do Lifton Coast. Here I can do a little one, so I left and I brake, oh brake too late. Here we go, got the apex, all okay. Here in this corner it's much more tricky to do Lifton Coast just because there's very little phase to slow down the car, but also people cannot overtake you through that here, Lifton Coast. Here people cannot overtake you, so you can actually do more Lifton Coast than then you know ideal. So obviously the challenge at one point is finding where to defend, a little bit of Lifton Coast here and we brake. Where to defend versus others and where not to lose too much lap time. So this is really the big challenge that the guys are facing in the formula e-Chamberchip. This is really how you manage the race, so it's very easy to be fast at the beginning and to get places, but if you burn too much energy then that means you need to do even more Lifton Coast, so it's just finding the right balance between attacking, going fast. So in a perfect world you want to create a small gap with a guy behind maybe two seconds and then you can manage your Lifton Coast exactly where you want, but that's the challenge that the guys are facing and I know I suggest that we go and watch them race.
