A pair of GranTourismo MC will spearhead the Maserati challenge at this weekend's 6 Hours of Vallelunga.

The two cars will be in 2011 with additions to ensure faster pitstops during the race. The lead entry of the two cars – which will run the GT Cup category – will be driven by two of Maserati's regular drivers in the FIA GT1 World Championship Alessandro Per Guidi being joined by Andrea Bertolini, who leads the championship with just two rounds remaining. Per Guidi already has race wins this year with the MC, taking two wins the GT4 European Cup at Paul Ricard and another pair at Brands Hatch.

The GT Cup-spec car will feature uprated aerodynamics, brakes and engine compared to the GT4 example.

The second car will be shared between Phil Baastians and Lorenzo Casè. Dutchman Baastians is a past champion in both Renault Clios and Alfa 147 competition in Europe, as well as having several starts in the Spa 24 Hours. Casè, perhaps more immediate experience for the race, again having driven the car in GT4 spec in the GT4 European Cup last year.

A single example of the GT4 machine will be in action at the Italian track in the hands of a Swiss privateer team and driver Andrea Chiesa and Gabriele Gardel.
