This was the final day of a two day test at the Spielberg circuit that hosted last Sunday’s Austrian Grand Prix. Fortunately, the rain that blighted Tuesday’s session kept away today and so track time proved more useful for everyone. This was also the very last day of in-season testing for 2015. After Max Verstappen drove yesterday, today the STR10 was piloted by a man more used to racing “tin tops,” the reigning DTM champion, Marco Wittmann.
Phil Charles (Chief Race Engineer) “We’ve had a very productive day, completing a high number of laps, with Marco making no mistakes and impressing us all with his approach and feedback. There was a short time of adjustment as he got used to the difference in braking from the DTM car to a Formula 1 machine. He then settled into a rhythm, as we started off our programme with a series of long runs. After that, it was time to proceed with the items on our test agenda; aero, tyre and set-up work, with some performance runs in the middle of the day, mainly for the driver’s benefit.”
Marco Wittmann (Car 38) “This has been an amazing experience for me. I was surprised at the power of the car; if I compare it to DTM, it’s got quite a lot more power! I enjoyed the whole day, which was trouble free, so I was able to do a lot of laps. I’m happy with my day, I hope the team is too. I would like to thank Red Bull, Scuderia Toro Rosso and BMW for giving me this great opportunity.”
