With every model-year, the 911 undergoes a few aesthetic and mechanical modifications, but the car retains its legendary trademark silhouette. There’s a wide array of models offered, which are defined mainly by their engines and powertrain. All are six-cylinder flat engines, with or without a turbocharger. Besides the Carrera and Turbo, two exceptional versions are being marketed: the GT2 and GT3. The exciting and very exclusive Speedster is one of the newcomers this year.
