Flash Engineering signed on several new sponsors, the Swedish mailservice "Posten" among others, for 2006 and dramatically increased their available funds. They also signed on double Swedish champion Richard Göransson and former Flash Engineering Volvo driver Edward Sandström. Göransson and Nilsson drove new BMW 320si E90 cars for the 2006 season, while Sandström drove the older BMW 320i E46. Richard Göransson finished second in the championship while Nilsson was 9th again. Sandström was involved in a major accident early in the season in which the car was completely destroyed, and Sandström had to sit out the remaining races.
