Last week Tim closed his article on the TTA Saab with this sentence:
Flash Engineering and Team Tidö will test the car for the first time on a secret location sometime next week.
Sometime next week is sometime this week, and thanks to Saablog-in we have found out that the car is being tested in the circuit Alès near Nimes in southern France.
Alès is only 160 km from Venelles, where Solution F is based, so maybe this is the reason why they have tested the car there.
And yes, I would have preferred to see a 9-3 Griffin silhouette like the CGI pictures from the presentation.
