Violent g-force, cockpit temperatures over 40C, and the constant threat of a crash: Formula 1 drivers are under intense physical pressure on the track. But what happens when emotional pressures boil over? At the Hungarian Grand Prix in August, McLaren is about to find out…and how. An extraordinary incident in the pitstop seems to suggest Fernando Alonso is playing tricks on Lewis Hamilton - but as is often the case in Formula 1 things are not always as they seem. Tensions boil over, culminating in a season-changing ultimatum for Ron Dennis.
