Returning to the current 918-generation models, we’ve spied Porsche testing a track-addicted Cayman on numerous occasions and while the name hasn’t been officially confirmed, you should expect this to wear the RS Spider moniker.
Nonetheless, a recent winter spy stroll brought us a similarly-gifted open-top version, which means Porsche is currently working on a Boxster RS Spyder.
A ducktail spoiler on the Boxster, againThe prototype sports Porsche’s famous Ducktail spoiler, a move borrowed from the 987 Boxster RS - we’ll remind you the aero element was born back in 1973, when the Neunelfer moved from rally racing to GT motorsport. As for the street debut, the Ducktail first appeared on the 1973 911 Carrera RS 2.7.
Sorry, we forgot this is not the 911, so we don’t have to start the description of the prototype from the rear. Moving to the front of the Boxster GT4 test mule, we find the same apron from the Cayman GT4 prototypes, but while those have already shed the camo, the Boxster test car still has it. The 911 GT3-like upper vent is on the house.
As for the tech package, while the Cayman GT4 is expected to squeeze between 370 and 400 horses from the same 3.4-liter flat six used for the S and GTS models, the Boxster GT4/RS Spyder will fall about 10 hp behind its coupe counterpart. While Porsche explains the level of performance the 911 GT3 has reached means a manual would only slow most drivers down (you can only have it with a PDK), the Boxster prototype here sported a three-pedal arrangement.
Both will also be put on a diet that will see them lose about 50 kg (110 lbs), so we’ll enjoy an uber-focused swansong duet before the next generation of the models lands.
