Graham Hill finished second in this Lotus 49B at the 1968 U.S. Grand Prix; after sharing it with Jackie Oliver, for most of the season. This was chassis 49B/R6 which was driven to victory by Hill in Mexico later in the 1968 season. Graham Hill also drove this chassis during the first part of the 1969 season. He unfortunately, did not score anymore victories. After Hill was entrusted with a new car, chassis 49B/R6 was put in the hands of the newest Lotus team member, Jochen Rindt. The latter scored his maiden Grand Prix victory at Watkins Glen in October 1969. Rindt also drove 49B/R6 to victory at Monaco in May 1970, and driver Alex Soler-Roig made a final appearance of this Lotus 49B while attempting to qualify it at the French Grand Prix in July 1970.
