Häkkinen followed this up by taking consecutive podiums in the next two rounds—third in France and second in Britain. He managed further consecutive victories in the next two rounds, and followed this up with a sixth-place finish in Hungary. In August, it was announced that Häkkinen and Coulthard would be retained for 1999. Häkkinen retired from the following race held in Belgium when Ferrari driver Michael Schumacher collided with the Finn and was also hit by Sauber driver Johnny Herbert. He later managed a fourth position in Italy despite suffering from brake problems resulting from a spin. Häkkinen finished the season by taking victory in the final two rounds at the Luxembourg Grand Prix and the Japanese Grand Prix, which ensured he took enough points to clinch the 1998 World Championship, with 100 points, ahead of nearest rival Schumacher. Häkkinen was awarded the Autosport International Racing Driver Award for 1998. He was also named the Finnish Sports Personality of the Year by journalists. The Finnish Post Office issued stamps to commemorate Häkkinen's World Championship in January 1999.
