Porsche's new track weapon hits the Nurburgring.
It wasn't very long ago when Porsche was caught testing the all-new 911 GT3 at the Green Hell. But it turns out this wasn't the only new high-performance sports car Porsche brought to the Nurburgring. After being spied in the snow last month, the long-rumored Porsche Cayman GT4 RS has returned to its more natural track habitat. Spied during a recent Nurburgring test pool session, our sources say Porsche's new track weapon looked like it was setting some "very quick" lap times.
Compared to our last sighting in Sweden, the GT4 RS prototype has been fitted with the same massive rear wing featuring a swan neck-style mounting we saw on the 911 GT3 prototype last week.
The center lock wheels are gone, but the cooling vents on the hood have returned. These prototypes could represent different stages of the car's development, or Porsche could be testing different components that may not be fitted to the final production car. One thing every prototype has in common, however, are louvres replacing the rear wide windows to provide extra cooling for the engine.
Powering the Cayman GT4 RS will be the same naturally-aspirated 4.0-liter flat-six engine as the regular Cayman GT4. In the current Cayman GT4, this unit produces 414 horsepower, but the hardcore RS version will reportedly boost the output to 500 hp, putting it in the same territory as the current 911 GT3. And no, Porsche won't resort to turbocharging to extract more power.
We're expecting the Cayman GT4 RS to only be offered with a PDK dual-clutch transmission since this setup will allow for quicker lap times. This is also the only transmission option for the 911 GT3 RS. Look closely, and you can even see the paddle shifters. Also expect Porsche to modify the chassis to make the RS version lighter and stiffer than the regular Cayman GT4. Sadly, we still have to wait a long time for the hardcore Cayman GT4 RS to break cover, as a recent report claims the reveal won't happen until late 2021 or early 2022.
