Series Manager: Ary.
This series will be raced in the second quarter of 2017 (Q2).
Described by British magazine Motor Sport as the ‘greatest racing car in history’, in addition to its Le Mans wins, the Porsche 917 – powered by an air-cooled, boxer, 12-cylinder, 4.5-litre, 520-horsepower engine – holds, to this day, the record for fastest qualifying lap, an incredible 3:13.90 done in 1971 by Pedro Rodríguez. Will the NSR scale version also break all the records at ASCC?
