2021 Porsche 718 Cayman GT4 RS spy photos and video

If the 2020 Porsche 718 Cayman GT4 doesn’t seem like enough, keep in mind that the German brand still hasn’t thrown every ounce of performance into the car.

Yes, there is a tougher 718 Cayman GT4 RS, or something like that, something that Porsche executives have been hinting at for years and is now testing in prototype form.

Spy photos and video (starting at mark 3:13) show a prototype that may resemble the standard GT4, but it’s hard to miss the new NACA ducts in the hood, the vents that replace the three-quarter rear windows and the huge car racing-style rear wing.

There should also be more power on the table, given Porsche’s past habits with other RS ​​cars, with rumors suggesting close to 450 horsepower. The GT4 features a new 4.0-liter 6-liter flat engine that delivers 414 horsepower and 309 pound-feet of torque.

For the GT4 RS, Porsche is expected to add borrowed internal parts from the 911 GT3’s 4.0-liter engine that is rated at 500 hp, specifically the titanium connecting rods and the GT3’s dry sump system. This could help the GT4 RS’s engine rev up more to produce more power.

The only transmission offered on the GT4 is a 6-speed manual with rev adjustment and the transmission is to the rear wheels via a limited slip differential. There were rumors of a dual-clutch transmission installed in the GT4, although perhaps this will be saved for the RS version.

There will surely be some chassis updates to go with the extra power and aerodynamic modifications as well. The GT4 already has adaptive dampers and a 1.18-inch lower ride height than standard 718 models. The cars also feature manual tilt, dropout, ride height and stabilizer bar settings.

It is unclear when the GT4 RS will debut, but it is likely to be revealed in 2020. What is also unclear is whether the related 718 Boxster Spyder will also receive RS treatment, though such a move is unlikely given the unconditional nature of the RS designation. from Porsche.
