Porsche 718 line-up has two top-of-the-line variants, the 718 Spyder and 718 Cayman GT4.

For the first time ever, the 718 Spyder and 718 Cayman GT4 share a technical base. This includes the newly developed four-liter six-cylinder naturally aspirated engine, together with a six-speed manual transmission. The boxer engine generates 309 kW (420 PS) in both models. Whilst the GT4 represents the entry-level GT road model from Porsche, the Spyder lends itself to all kinds of curves. Both rely on highly efficient aerodynamics, a full GT chassis and powerful brakes. The only difference Is one’s a roadster and the other a Coupe.

The 718 Cayman GT4 and Spyder outputs  420 PS and  delivers a maximum torque of 420 Nm between 5,000 and 6,800 rpm. The manual transmission sports cars can both break the 300 km/h barrier: the 718 Spyder has a top speed of 301 km/h, whilst the 718 Cayman GT4 reaches 304 km/h. Both models accelerate to 100 km/h in 4.4 seconds from a standing start.

Both sport cars get a newly designed single-chamber arch rear silencer for more efficient aerodynamics. The front section, which is optimized in the GT style, maintains the aerodynamic balance with a large front spoiler lip and so-called air curtains. As an open-top variant, the Spyder has a fold-away top and a rear spoiler that comes up as you hit 120 km/h.

Making the 718 track=worthy

Porsche Active Suspension Management damping system with 30 mm lower suspension lowers the center of gravity and improves lateral dynamics potential. Next, the Porsche Stability Management (PSM) operates with even greater sensitivity and precision here but can optionally also be deactivated in two steps. Then, there’s the Porsche Torque Vectoring (PTV) with mechanical rear differential lock and the GT4’s optional Clubsport package.

When it comes to braking, the cars have large aluminium monobloc fixed-calliper brakes. Porsche Ceramic Composite Brake (PCCB) is also available as an option. One new feature is that the 718 Spyder now runs on ultra-high-performance (UHP) tyres specially adapted by Porsche.
