The Italian automaker announced that it will debut the lightest and most powerful variation of te GranTurismo, called the Maserati GranTurismo MC Stradale, at this year’s Paris Motor Show.
With inspiration drawn from the GT4 race models and the Trofeo GranTurismo MC, the Maserati GranTurismo MC Stradale is a two-seater that promises top speeds of beyond 300 Km/h, and the company says that the car itself is a balance between road driving roads and race driving desires.
The Maserati GranTurismo MC Stradale features improved handling characteristics and increased aerodynamic downforce, plus the output level has been increased to 450 HP (336 kW) without an increase in fuel consumption.

Maserati press release :
Modena, September 20, 2010. The new Maserati GranTurismo MC Stradale will be the fastest, lightest and most powerful car in the Maserati range when it goes on sale in the first quarter of 2011.
Inspired by the Trofeo GranTurismo MC and the race-winning GT4 motorsport models, the two-seater Maserati GranTurismo MC Stradale that will debut at the Paris Auto Show will feature razor-sharp handling and will break the 300km/h barrier.
The GranTurismo MC Stradale responds to demands for a GranTurismo which can balance on-road driving needs with race-driving desires, incorporating the handling and aerodynamic lessons from Maserati’s three racing programs.
The GranTurismo MC Stradale produces more aerodynamic down force without producing more aerodynamic drag, it produces more power – 336kw, 450 hp – without using more fuel and it is more agile without sacrificing the GranTurismo S’s highly praised ride quality.
