GP Week : Issue 197
What is the rev range of the engine? It will normally be between 9500 and 11-five [rpm]. With an eight-speed gearbox, that will be the range in the first two or three gears but then, when you go up into sixth, seventh and eighth, it will be something like 1000 more than that. Nobody has done any testing in the rain yet. What happens if it rains? The race will be slower! Will it affect reliability? I don’t think so. In a way, it means that there will be crashes. In the races, it will be hard to say. The teams tested in Bahrain and there is not any rain there. If we have a rainy race, there could be some surprises. There could be something that we do not expect, that we have not explored. But, we do a lot of work on the dynos, to figure out what would be the optimum set-up. To what degree has this [project] taken you into new technological areas? At Renault, there is quite a lot of road car technology that we can learn from. There are quite of lots of guys that are working in different areas. Direct injection and turbocharging are areas that are well- known to our engineers. It is different in a way, because we have to apply it from road cars to Formula 1. It is not massively different, so we are basically going the one way. I would imagine that all the drivers have been on simulators. They would have practiced deploying the energy from the different systems. Are they locked in to which part of a circuit they will deploy that energy, or do they have some flexibility on how they do it, for the best performance? There has been a lot of work on the simulator but we are still in the phase of the driver deciding where it will be used. I think that all the [different] engines are similar on this, and there are some different things that you can apply – whether you are in a race, in qualifying, even on an out-lap or in-lap, in which you want to recharge or discharge your battery. There are a lot of scenarios that we practice, and we are looking at how close we are to the reality. But it is still a learning process. Who supplies other componentry to your team? We do not comment on who supplies what! Be sure, we are no doing everything on our own, but we do not publicise this. At what point did you get the Power unit dyno testing with a transmission from one of your customer teams? Good question. [Long pause]. It was last year [Another long pause]. It was October or November last year. When the gearbox was available, basically. F1 >>> TECH 21 GPWEEK.com // 21 GPWEEK.com // PARTNERS:
