is a 3.8 km (2.361-
Mi )
Motorsport Race Track located in
Prenois , near
Dijon ,
France .
Built in
1972 , Dijon-Prenois played host to the
Formula One French Grand Prix five times, and the
Swiss Grand Prix once. The first F1 race was run in
1974 on the circuit's original 3,2 kilometres (2-mile-long) layout; with lap times under the 1-
Minute mark, there was an extreme problem with congested traffic between the race leaders and the backmarkers. Therefore, an extension was added to lengthen the circuit, as well as to reprofile many of its corners, by the time F1 returned to Dijon in
1977 .
Although Formula One has not returned to Dijon since
1984 , the circuit continues to be used today for minor, local races. Also, several
Swiss racing series use this circuit, as motor racing is still banned in Switzerland.
