214 g centimetre(s)
United States (Fort Worth)

Indycar driver Kenny Bräck (SWE) survived a split-second deceleration of 214 g during a 220‑mph (354‑km/h) crash on lap 188 of the Chevy 500 at Texas Motor Speedway, USA, on 12 October 2003. This is according to data registered in Bräck’s in-car “crash violence recording system”.

Bräck suffered fractures of his right femur, sternum, lumbar vertebra and ankles when his Dallara-Honda made wheel-to-wheel contact with Tomas Scheckter's car, sending his vehicle high into the air and into a steel fence post. The in-car information system registered a peak value of 214 g for a fraction of second; for comparison, the maximum g-force felt by astronauts on the Space Shuttle during launch and reentry was 3 g.
