The racing version of the GranTurismo, the Maserati GranTurismo MC Stradale is featured in this next video shot at the Valencia track.
Described by the company as the lightest and most powerful model ever built by Maserati, the GranTurismo MC Stradale extracts its juice from a 4.7-litre V8 that develops 450 horses (336 kW) and 510 Nm of torque.
Also take into account that the Maserati GranTurismo MC Stradale is 110 lbs lighter than the GranTurismo S, so you will understand why accelerating from 0 to 100 Km/h only takes 4.6 seconds. The Maserati GranTurismo MC Stradale has a top speed of over 300 Km/h.
