It was “Top Secret” when the streets of Adelaide were mysteriously closed down between 9.30pm and 11pm, on Wednesday 27th September. 

The roar of high-performance cars and motorbike could be heard rumbling through a circuit in the city.

You could have caught a glimpse of three Formula One cars, a Peter Brock Torana race car and a Superbike.

The impromptu circuit was used to film a short promotional video for the upcoming Adelaide Motorsport Festival to be held on December 9 and 10 at Victoria Park.  

Our very own Mark Soderstrom got a cameo too check it out.
