The Brabham BT26 was designed for the 1968 racing season. The concept proved to be quite disappointing, with the Repco engine designed by John Judd and Norman Wilson proving very unreliable. The car was longer than the BT24, the tracks were wider and the tires were bigger. The BT26 was the last F.1 Brabham to have a tubular chassis. Gradually, the BT26 received updates, including particular aerodynamic appendages, without the results improving. For 1969 the chassis was modified to accommodate the Ford Cosworth DFV engines: the first car was purchased by Frank Williams while the official team used three other chassis. Jack Brabham achieved a first victory at the International Trophy, while Ickx won in Germany and Canada. In that year Brabham ranked second in the constructors' championship.
