Porsche’s entry-level sports car and roadster have finally gotten the GT treatment and for the first time ever, the Porsche 718 Cayman GT4 and 718 Spyder shares the same technical base.
Both models are now powered by a 4.0-litre naturally aspirated flat-six petrol engine that is adapted from the engine found in the 911 Carrera Turbo. The boxer engine now generates 420 hp and 420 Nm of torque and revs out to 8,000 rpm.
Sprinting from 0 to 100 km/h takes 4.4 seconds while top speed is registered at 301 km/h on the 718 Spyder and 304 km/h on the 718 Cayman GT4. A 6-speed manual transmission is retained for maximum driving pleasure.
Porsche has made great strides with the 718 Cayman GT4’s aerodynamics, now with 50% more downforce compared to its predecessor without increasing drag. The fixed rear wing also produces 20% more downforce than the model it replaces, additional 12 kg at 200 km/h while the newly designed single-chamber arch rear silencer and diffuser accounts for 30% of the downforce at the rear axle.
The 718 Spyder also shares the same aerodynamic innovations but swaps the fixed rear wing for an active spoiler that deploys at 120 km/h. Like the models that came before it, the Spyder gets a lightweight removable fabric roof that can be stowed away under the boot lid in a few steps. Porsche assures that the soft top can cope at maximum velocity.
Other chassis developments from the GT division include new lightweight spring-strut on the front and rear axles, Porsche Active Suspension Management damping system that lowers the ride height by 30 mm as well as recalibrated Porsche Stability Management (PSM) and Porsche Torque Vectoring (PTV) with mechanical rear differential lock.
Exclusive to the 718 Cayman GT4 is the optional Clubsport package that adds a rear steel roll bar, fire extinguisher and six-point harnesses for the driver.
