Robert Kubica crash in Montreal
Data released from Robert Kubica's crash at the Canadian Grand Prix in Montreal shows just how lucky the BMW-Sauber driver was to escape with relatively minor injuries.
According to the onboard accident data recorder, Kubica hit the wall approaching the hairpin turn at 230 km/h and experienced a 75-G impact.
Former Lotus engineer Peter Wright, who is now the head of the FIA safety commission, studied the data and concluded that all of the safety measures worked perfectly.
To put it in perspective, F1 drivers usually experience g-forces of 5 when under heavy braking and 4 while going through a corner.
Former F1 driver David Purley is believed to have survived a 178 g crash during pre-qualifying for the British Grand Prix in 1977.
