The debut could be just a few months away.
Earlier spy shots and videos already provided nearly undisguised looks at the 718 Cayman GT4. This one is the same. There is visible concealment on the headlights and taillights, but the coupe looks otherwise to production specifications.

The model will reportedly use a naturally aspirated 3.8-litre flat-six making 420 bhp. Initial examples will have a six-speed manual, but a dual-clutch gearbox will allegedly join the range in late 2020. In addition to the extra power, the model will also potentially have tweaks like thinner glass and a more spartan cabin to help cut around 50 kilograms.
The new Cayman GT4 will allegedly debut at the Goodwood Festival of Speed in July – a great spot for unveiling the hardcore model to the many enthusiasts in attendance there. It's not yet clear whether the 718 Boxster Spyder will get the same powertrain but the open roof variant could be at Goodwood, too.
For customers who want to go racing, Porsche also has the 718 Cayman GT4 Clubsport on the way. The track-only model uses the 3.8-litre flat six and a six-speed dual-clutch gearbox. Natural-fibre composite covers the doors and rear wings. The material is similar to carbon fibre in weight and stiffness, but the fibres come from flax and hemp. The standard Trackday variant costs £130,300 plus VAT.
