Everyone’s aware that Porsche’s working on a new 911, but at the same time they’re also making the final adjustments to the 718 Cayman GT4.

The most anticipated version of the car comes dangerously close to its larger and more expensive siblings in terms of performance. And it does so with a little help from the latest 911 GT3 – or its naturally aspirated flat-six engine, to be more accurate.

The 4.0-liter boxer unit produces 500 PS (493 hp / 368 kW) and 460 Nm (339 lb-ft) of torque in the 911 GT3, and will probably put out about 100 PS (99 hp / 74 kW) less in the upcoming Porsche 718 Cayman GT4. That should be an improvement over the previous iteration and its 911 Carrera S-sourced 3.8-liter flat-six that was making 385 PS (380 hp / 283 kW).

Porsche will probably offer it with a choice of two transmissions: a six-speed manual and a dual-clutch automatic, just like the 911 GT3. The previous GT4 sped to 62 mph (100 km/h) in 4.4 seconds and hit a top speed of 295 km/h (183 mph), so we expect its replacement to beat those figures.

Visually, the 2019 Porsche 718 Cayman GT4 will be easily distinguishable from the rest of the range thanks to the aero package that’s partially visible in the following video. The footage shows a prototype of the car testing at Italy’s Monza track, and reveals the sonorous engine under heavy throttle once again, so you may want to turn up the volume before clicking play.
