Tsunoda’s car somersaulted into the barriers after only six minutes as the 25-year-old Japanese driver, who has good experience of racing at the Autodromo Enzo e Dino Ferrari circuit, lost control when he hit the kerbs at the Variante Villeneuve.
His car lifted and flew sideways before turning upside down into a single barrel roll before skewing into the barriers.
He was unhurt, but the session was red-flagged to a halt as he climbed from his car and walked away. (AFP)
