 Although regarded by its designer as a " lash @-@ up " , BT19 had a very successful Formula One racing career , almost entirely in the hands of Jack Brabham . BT19 was entered in several non @-@ championship Formula One races before the beginning of the 1966 world championship season . At the non @-@ championship South African Grand Prix at East London on 1 January , BT19 was the only new 3 @-@ litre car present . It recorded the fastest time in the qualifying session before the race – therefore taking pole position for the start of the race – and led the majority of the event before the fuel injection pump seized . Similar problems stopped the car on the second lap of the Syracuse Grand Prix in Sicily , but at the International Trophy at the Silverstone circuit , Brabham set pole position , a new lap record , and led the whole race to win ahead of 1964 champion John Surtees in a 3 @-@ litre works Ferrari .
