It’s safe to say that the 718 Cayman GT4RS has been Porsche’s worst kept secrets of all time, almost as bad as the C8 Corvette. Just this week, the new 718 flagship was spotted going flat out on the Nurburgring with little to no camouflage; it was going really fast too.
The test car was sporting some new NACA ducts along with center lock wheels, and some louvers on the rear windows to aid in cooling. Does it look good with those upgrades.
Officially, the GT4RS doesn’t even exist so there are no real specs available to the public. The internals of this car have actually been very well kept from the public despite Porsche’s horrible attempts to keep the car under wraps. Considering that the current 718 GT4 makes 414 hp and does 0-60 in just 4.2 seconds with a manual transmission showcases the sheer potential that the GT4RS has.
From what we’ve seen-and heard-from the Nurburgring, it’s clear that the GT4RS is coming powered by a naturally aspirated flat 6. More than likely a heavily modified version of the 4.0 liter flat 6 in the current GT4. As far as power goes, expect no less than 450 hp although there have been rumors of the car pushing 500 hp. 500 hp in a >3200 lbs car with a properly geared PDK transmission is a recipe for a supercar killer.
Knowing Porsche, the GT4RS will most likely be slower than the upcoming 992 GT3 for the sake of preserving their hierarchy but I wouldn’t be surprised if it completely walks all inferior 911 models; possibly even previous generation GT3s.
Only two questions remain now: When will it be revealed and will there be a Boxster version as well? In my unprofessional opinion, I would say the GT4RS is either going to be revealed slightly before or alongside the new 992 GT3. Given the pandemic, these reveals will likely take place online rather than at an auto show. As far as a Boxster Spyder RS, I’d say it’s pretty unlikely since we haven’t seen any prototypes and the idea of a Boxster track car doesn’t really make sense (that’s why the GT4 is there). Other than that, it’s looking to be a pretty big game changer and I can’t wait to see what the future holds.
