LONDON, July 15 — Formula One’s governing body said today it will introduce tougher tests on the roll hoops of cars next season as a result of Chinese driver Guanyu Zhou’s big British Grand Prix crash.

Zhou’s Alfa Romeo flipped and skidded upside down along the track at Silverstone, with the roll hoop ripped off, before flying across a tyre wall and becoming wedged between the barriers and catch fence.
