Sunday 24th September 1989
Gerhard Berger took his first, and only, victory of the season for Ferrari at the Portuguese Grand Prix. Alain Prost finished in second place for McLaren, strengthening his championship chances after his team-mate and rival Ayrton Senna had been involved in a collision with Ferrari driver Nigel Mansell which resulted in them both retiring. Mansell had just been black flagged at the time of incident for reversing back into his pit box after overshooting it during a stop. The podium was completed by Stefan Johansson, who took both his last and Onyx’s only podium, and also Onyx’s last points. During the race, Pierluigi Martini managed to lead a lap for the only time in both his and Minardi’s time in Formula One. Ten drivers from ten different teams finished in the top ten places in the race, with Jonathan Palmer scoring his last ever point in sixth place. The race was also Alain Prost’s 150th Grand Prix start, and Coloni’s last, though it attempted races for another two years without a single start.
