Porsche's 718 family consists of the Cayman and the Boxster. But by choosing the 420 horsepower atmospheric 6-cylinder engine, the choice comes down to between the 718 Cayman GT4 and the Cayman Spyder. The PDK gearbox is double clutch. With active suspension, chassis lowered by 30mm, electromechanical steering with variable assistance, mechanical self-locking differential and torque vector system, the Spyder follows the characteristics of the GT4 but does not offer the same chassis adjustments possibilities.
