Here’s a video from BMW TV showing a “billed” secret testing facility in Miramas in the south of France.
The test facility is the usual gated compound but the track is surrounded by public highway and even google streetview has photographs of this “area-51”.
Anybody with step ladders can gain Photography from this location.
BMW invited a select few M customers, to be exposed to the many variants of the M3 including the M3 GTS and the GT4 Track variants.
Enjoy the Video:-
