Volvo, which had been competing in the BTCC since 1994, partnered with the newly founded Halmstad-based racing team, and provided financial support and the cars.
Nilsson kept the name "Flash Engineering" and formed a new, independent team, driving a BMW 3 Series.
Porsche appointed Flash Engineering as promoter for the one make-series Carrera Cup Scandinavia in 2005.
The team is also going to run three cars in Carrera Cup Scandinavia for Price Carl Philip, Roar Lindland and Matte Karlsson.
Flash co-founded the TTA – Racing Elite League in 2012, entering two Saab 9-3 for Robin Rudholm and Mattias Andersson.
The team returned for the 2016 STCC season with drivers Björn Wirdheim, Reuben Kressner and Linus Ohlsson.
