Following this past week’s unveiling of the GranTurismo MC GT4 comes a second Maserati race car, this time based on the four-door Quattroporte saloon. The new car is set to debut in the 2009 Superstars Series and driving it, on behalf of the Swiss Team, will be former F1 driver Andrea Chiesa.

The Superstar Series is a European touring car event that sees sedans from various generations compete, including cars like the BMW 5-series dating back to the 1980s, as well as the Chrysler 300 and some Cadillac models.

In racing spec, the Quattroporte develops more than 450hp (336kW) from its 4.2L V8 engine and its kerb weight has been reduced to around 1,430kg. Other modifications include the addition of a sequential manual gearbox, new Pirelli tires, and a few minor aerodynamic modifications.

The Swiss Team are still working on the chassis development for the new race car and hope to carry out the first test sessions in the lead up to the first round of racing at Imola, Italy, on April 19.
