Porsche is bringing out the big guns for this month’s 2009 Frankfurt auto show, with no less than four world premieres set to take place on the automaker’s stands.

The 911 Turbo (Coupe and Convertible), the 911 Sport Classic (limited to 250 examples), the 911 GT3 RS--and its motorsport twin the 911 GT3 Cup race car--are making their debut at the show, and each is the embodiment of the characteristic sporting dynamism associated with Porsche. The Frankfurt auto show also marks the European introduction of the four-door Panamera Gran Turismo.

The facelifted 911 Turbo is the most dynamic high-performance sports car in its class, as well as the most fuel efficient. Porsche is also introducing the 911 GT3 RS, with its very direct connection to motorsport, and this will be joined by the race-ready 911 GT3 Cup car.

The fourth world premiere is the 911 Sport Classic, which can be recognised at first glance by its fixed rear spoiler in the form of the legendary ‘ducktail’ from the Carrera RS 2.7 of 1973 and distinctive double-dome roof.
