FIA Institute Academy performance manager Robert Reid says the drivers have shown the biggest improvement yet since joining the scheme after their latest training session in Chamonix this week.
All but one of the drivers attended the five-day workshop in the French Alps, the final classroom session before the on-track instruction begins next month. The focus from the FIA Institute was on planning, following on the from the fitness work which was completed in Edinburgh last month.
Former world champion Reid said: "There was a feeling that some of the drivers might not have understood the link between the training we're doing and the track or stage. After Chamonix, they absolutely get it - you can see that. This workshop has been fantastic, we've seen the guys all coming together and working as one.
"We've done stuff like rock climbing and dry tooling, not to mentioned climbing a mountain, but when you're up a crag at the end of a rope and your life is depending on your team-mate down below, it does tend to forge a bond. Like I say, the guys have got it now - we've made some really big progress with them all at this session. It's been very satisfying to see."
Swedish Formula Renault Eurocup racer Timmy Hansen was full of praise for the second of six workshops. He said: "In the last five days, I really feel I have become a better team player. People might think in our sport that there is only one driver in the race car, but, just to get out on to the track you are dependent on the whole team. One of the things which helped us become a team, was the rock climbing.
"I have never done this before and I thought it was so nice! I loved it. The adrenalin rush was incredible, just the same as when you have a big moment of oversteer in the car or when you make an overtaking move that works - this was the same. This has been fantastic."
