“There was only one rally where we did not finish at least second. It wasn’t superior outright performance of the car, but of the whole team. All the drivers were quick, not just one driver.“Reliability is for sure fundamental to all of that, but it isn’t just reliability. We had all the drivers win one rally, they should have all won two (we screwed up in Argentina and Elfyn Evans should have won that rally easily), but we had some stuff going on which didn’t help him and he lost it by a fraction of a second.

“The engine technology has been reasonably stable. Yes, we now have a bigger restrictor, but the base regulations are where we are since 2011. We have quite a lot of knowledge on that. “There are always bits we’re finding and we are picking up a bit here, a bit there. To pick enough up to make a big change is not easy.

“Damper technology is always moving quite a pace. I think this is where you’re going to see the differences, but I don’t think any team is going to make a sudden step forwards.”When you talk about transmission, is this in relation to learning more about the operation of the central differentials? “Yes, probably. Interaction between differentials is something you can develop when you try and look at the way they work as a whole, and try to balance them in different circumstances.” What particular changes have arisen in the regulations for 2018 World Rally Cars? “Nothing major really in the regulations. There’s nothing significant that’s changed from last year to this year. Little bits and pieces. “I think the biggest impact for us is a new tracking safety system. That is probably the single biggest new thing for everybody to get used to in 2018. Otherwise, we’re very much where we were last year, regulation-wise.”

“We are reasonably happy with our aero package, we’ve changed the sills and some other bits and pieces, but again we don’t make a big step change. We are just refining the original architecture we have.“If you were to do it again you could again adopt a different philosophy, but that would be outside of the jokers that are available at the moment. When we look to design the car next time there are some large architectural changes you could make, but at the moment it’s all refining, optimisation really.” Looking around at the other World Rally Car teams, are there any particular neat opportunities taken by other teams that have given them an advantage, or a particular innovative design feature which they took a risk on being able to use and found it worked? And how do you view the other three teams? “It’s hard to say. People have done different routes for different reasons.

“Slowly all the cars are going in a similar direction now. You will see aerodynamic features that are similar amongst the cars, slowly going one direction, though there are some differences still.“We’ve made some choices, architectural choices, that maybe others have gone a different way, I don’t know. I’m happy where we are, I don’t tend to look too much at the other cars. “We tend to look at our car as we know how it all integrates and works together. “Trying to bolt on someone else’s perceived advantages is not the way for us! It’s trying to evolve our car as best we can.”
