Williams driver Kazuki Nakajima has walked away from a high-speed crash on a day of testing at Circuit de Catalunya in Barcelona.

Nakajima was driving the new Williams FW30 when he went off-track on the first corner at 11:25am local time. The area has recently been changed from being a gravel trap to plain asphalt meaning his car did not slow down before smashing into the crash barrier head-first, severely damaging the front of the car.
