Porsche 718 Boxster Spyder prototype spotted with RS induction and centrelock wheels

Porsche might be on track to apply some of the GT4 RS’s tricks to the 718 Boxster Spyder

Porsche Cayman GT4 RS, 911 Sport Classic, GT3 RS, 911 Safari – there’s already a myriad of incredibly special Porsche’s that have already been recently revealed, or are just about to be, but fresh images of a new prototype based on the current Boxster Spyder have now surfaced revealing that there might be another super special model in development.  

From the images the new model is clearly a 718 Boxster Spyder, but it’s fitted with some curious additions that look to be derived from the new Cayman GT4 RS. These include the RS’s centrelock wheels, but of more resonance (excuse the pun) are a pair of snorkel-like intakes that sit up on the rear tonneau in a position usually used for tie down points for the Spyder’s part-electric fabric roof. As a result, it does without (the largely aesthetic) strap-downs, giving this prototype a different silhouette.

The snorkels themselves are placed in largely the same position as they are on the GT4 RS, suggesting that under the tonneau sits the same intake plenum, and therefore possibly the same GT3-derived 4-litre flat-six engine. In the RS the engine is rated at 493bhp, 10bhp down on the GT3 due to a more complex exhaust system – but it’s applicable packaging does mean it could find its way into this Spyder derivative without too many technical challenges. 

It must be noted that while it might be easy to call this a new Spyder RS, there are a few reasons why it’s unlikely to be the case, as first and foremost the GT4 RS’s wider front axle and bespoke front wings have not been carried across, nor the modified front bumper or the dual-layer exhaust outlets. 

This, together with the fact that Porsche’s GT department flatly doesn’t do open-top versions of its series production RS models, means that this is most likely to be another limited run special being developed and engineered by Porsche’s Individual department. 

This fact has was quantified during a conversation with Porsche Individual during the launch program for the Sport Classic, suggesting that more models with a GT engine like the previous 991.2 Speedster and 911 R were on their way alongside the ‘decades’ series that include the recent Sport Classic and Targa Heritage Edition before it.

This new model's development by the Individual department also means it doesn’t have to conform to the RS's rules, meaning it might just pick up a six-speed manual where the GT4 RS is PDK-only – a convention that only applies to Porsche’s GT department. 

So while the possibility of a Spyder RS (or RS Spyder, which just sounds better right?) might sound extremely appealing if it were derived from Andreas Preuninger and his GT department, its existence might be a little more specialised and a little less affordable (in relative terms) than the GT4 RS on which it is likely based. Still, with one more super special Porsche to look forward to, we’re not complaining.
