in a short distance. Downforce in the era of Group C
cars helped braking to some degree but presently cars are tending towards low downforce to seek higher speeds in the face of power limiting regulations.
The track, which basically was a triangle from Le Mans down south to Mulsanne
, northwest to Arnage
, and back north to Le Mans, has undergone many modifications over the years, with CIRCUIT N° 14
being in use since 2007.
