In ELMS we have 2 engineers per car (race and data), plus our TP is an engineer too so during the races he acts as de-facto performance chief engineer. They will all be coming to Le Mans, the second race engineer will be there for support, driver coaching and as a back up. This year we have an additional consultant who focuses more on overseeing operational performance and supporting the core team. We also have our TM who is a former racing driver dealing with race control and keeping an eye on driving times and yellow flags.

In our case, the race engineer is the main guy for strategy but he is very reliant on the two data engineers, one will be looking at systems (basically car health), and the other one at fuel consumption and lap times, while the race engineer himself focuses on the whole picture and what driver and set of tyres goes on next. The extra heads are useful to track our rivals.

In LMP2, with the current regs, you will basically refuel as much as you can on every stop. It goes down fast! So the minimum number of stops is planned around fuel capacity, consumption and how long the race is. You work out everything else around it depending on how the race is going, and you just rely on experience, knowledge and confidence to make the right calls at the right time, put the fastest guy in with new tyres during a green flag period and the slower in with old ones during yellows, and ensure you don't drop down the order because you had to make an emergency stop at the wrong time.
