A sixth constructor in Norma Auto Concept has been granted a licence to build cars for the new LMP3 category.
Le Mans organiser the Automobile Club de l'Ouest, which launched the P3 prototype division for last season, has decided to extend the number of allowed chassis for a second time courtesy of the success of a class that has attracted 21 entries for this season's European Le Mans Series.
That success resulted in the ACO reopening the selection process to companies that had bid for the fifth licence that was awarded to Japanese constructor Dome last October.
Norma will be the last licensed constructor for LMP3, according to the ACO, and joins Dome, Ligier, Riley-Ave, ADESS and Ginetta.
Founded in the mid-1980s by Norbert Santos, Norma is best-known for building a line of successful hillclimb cars and Group CN prototypes.
Its chassis have also raced at the Le Mans 24 Hours on four occasions.
A Ford-engined LMP900 competed in the 24 Hours in 2003 and its LMP2 M200P with Judd/BMW power took part in 2010-12 (pictured).
