For , Boutsen left Benetton to join Williams and was replaced by rookie Johnny Herbert. The new engine developed by Ford for the B189 was not ready for the start of the season, and the previous year's engine did not fit in the new car. The team therefore had no choice but to continue using the B188. Despite this setback, the B188 still proved competitive, with Nannini claiming a podium finish at Imola. Prior to making his Formula One debut, Herbert was involved in a serious crash in Formula 3000 that broke both his legs. Despite achieving some impressive results, including 4th place in his first race, he was dropped by the team after failing to qualify for the Canadian Grand Prix as it became clear he had still not fully recovered. He was replaced by rookie and McLaren test driver Emanuele Pirro. The B189 was finally ready to compete at the following race. Nannini would go on to achieve Benetton's first victory since 1986 at the Japanese Grand Prix after Ayrton Senna was disqualified. Pirro was only able to secure a single points finish in his ten races with the team, taking 5th place in Australia. Benetton ended the season 4th in the championship with 39 points.
