F1 Mexican Grand Prix: Rear wing DRS flap fault causes Bottas off

Valtteri Bottas says a fault with his rear wing DRS flap caused his crash during free practice two in Mexico as he struggles with the slippery surface
Valtteri Bottas says a fault with his rear wing DRS flap caused his crash during free practice two in Mexico as he struggles with the slippery surface of the Autodromo Hermanos Rodriguez.

The Williams driver recovered from his high-speed off at turn one to end the second free practice session seventh quickest during a testing Friday. The Finn explained under braking his DRS flap – which was open down the long pit straight – failed to shut correctly under braking which produced a lack of rear downforce and his Williams spun into the barriers.

“The rear wing stalled,” Bottas said. “When I braked and the DRS closed it was still as if the DRS was open. We then made some modifications to the rear wing level and then it was okay.”

Reflecting on his first experiences of the Mexican track he felt he was suffering with a lack of downforce like the majority of the F1 field and it was causing the circuit to be extra slippery.

“The circuit seems nice but it's so slippery. On top of the altitude that brings a loss of downforce," he said. "The surface is really slippery so it was difficult to get the tyres to work and to get the tyres to really bite on the surface. That was the main problem today and I'm sure everyone was sliding around.

“We have plenty of work to do to get them working better. I improved more than two seconds with the option. The track will improve the more we run and there's definitely more in it but we need to find more to really make the tyres work.”
