During the SCC500 Rolling50 1000 I have filmed this BMW M5 F10 tuned by Swiss car tuner Hifhperf. They have changed the exhaust to Akrapovic Exhaust, new downpipes, BMC filter and RRahmani software remap. Engine output is now around the 720HP! You will see some accelerations, donuts, revving and drag racing against other supercars! It did a drag race of 1000 meters with a rolling start of 50 km/h with best VMAX: 272.79 km/h!
