Ross, have you got the same economy targets that were placed for the four cylinder engines or do you need to reduce the ambitions?
No, we're keeping the same efficiency objectives that we had with the straight four, [it's] probably be a little bit more challenging with a six but we want to keep the same efficiency objective, and one of the objectives is to increase the targets in terms of lowering them in future years, so that can be the target for the engineers to try and achieve increasing performance or keep maintaining the performance with less and less fuel, which I think is a really interesting challenge. What we don't want is a situation where we have an amount of fuel you race with and you might run out on the last lap. We don't want that. We want measured fuel efficiency, maximum fuel flow rates and try and control it in a way that still encourages interesting and exciting racing.
