As the days progress from Test 1 and on into Test 2, you’ve got the car up to speed and you’ve been through all of the basic systems checks, then you’re really into core reliability and core performance tests.
We’re always mindful in the teams that the drivers do need to start getting a feel for the car at the limit of its performance envelope. But the reality is that there’s such a lot of data to collect, and the only way to collect it nowadays, really, is during the winter tests. Because of that we have very prescribed tests across Weeks 1 and 2, and we need the drivers to perform in a certain way during those tests – and that rarely involves driving the car as fast as they can.
Sometimes, we do actually want the driver to push the car to the limit of its performance envelope, because without that, we’re then not going to get the data that we need. If we’re testing, say, a new front suspension which has more castor in the car, which essentially gives you a little bit more camber and a little bit more turn-in in the initial part of the corner, then you will want the driver to push to the limit of the envelope and equally, you want their subjective feedback. You’ve got all of the objective data taken from the car, but what you need is their personal feedback, as well as what the all-important stopwatch is telling you.
But there’s more routine stuff still to get through in Test 2 as well. We might want to do constant speeds on the straights. You essentially put the car in cruise control at some speed, be that 120kph, 150kph or 180kph, and because you’ve then got the car in a steady state, neither decelerating nor accelerating, the quality of data that we can take from that is usually quite high.
Equally you might be doing constant speeds in a cornering condition – so Turn 3 in Barcelona, for example, is a great place to do that; you usually get the driver doing somewhere between 120-180kph through there, depending on the fuel mass and tyre grip they’ve got on the car, and it’s just about collecting all of the data that we can.
It might not be very glamorous, but all that data that the teams collect across Test 1 and Test 2 is going to put them in a much more favourable position by the time they get to Australia.
