In the open Porsche 911 Turbo S the wind from the airflow and the lusty boxer engine sound mix to create an incomparable feast for the ears. For the devotees of the brand from Zuffenhausen, the model is the optimum combination of relaxed cruising and high- speed curve dynamics provided by 580 HP at the rear. Watch out - that power is being released. That’s when the SIKU traction tyres are required for the transverse acceleration forces. The new Porsche 911 Turbo S Cabrio thus extends the already impressive SIKU fleet of sports cars that provide much driving fun, particularly with the roof down: BMW 645i Convertible (1007), Audi R8 Spyder (1316), Lamborghini Murciélago Roadster (1318), Bugatti Veyron Grand Sport (1353), Wiesmann Roadster MF5 (1320) and Bentley Continental GT V8 Convertible (1507).
