On arriving at the Bonneville Salts Flats they found out that part of the normal track was breaking up. So it was necessary to move the measured mile closer to one end of the timing stretch, thereby reducing the length of the run-in in this direction. Donald Healey drove the car on the straight-away runs and raised the International Class D for 5 kilometres to 182.2 mph and for 10 miles to 181 mph The car was timed over the kilometre at 192.6mph, thereby breaking an American National record. various other runs were completed and one such run broke the magic 200 mph barrier.
Then Carrol Shelby, the Texan driver who competed in many European events during the 1954 season, took over and attacked the International Class D record for the hour, which was duly obtained at a speed of 156.7m.p.h. For this run, a 10-mile circle was used, a course which seemed almost one long straight when seen from behind the wheel of a normal saloon but which seemed more like a rather difficult fast bend from the Streamliner’s cockpit. The car proved very stable, which was indeed fortunate, for conditions were by no means ideal, gusts of up to 30 mph. sweeping across the Salt Flats. Moreover, owing to the complete absence of trees or any other vegetation, the driver received no advance warning of a gust before it struck the car. This is where the tail fin proved to be of real value in such circumstances.
Austin-Healey at speed on the 22 August 1954 on the Bonneville salts USA this modified Austin Healey “100” was timed by the American Automobile association officials over a measured mile at a mean speed of 192.6 MPH. At the same time a number of Class D international records were broken. It is on such occasions that research and development are put to the severest test which motoring have so far devised – record-breaking.
