Porsche appears to be testing a new RS variant of the 718 Spyder, which could be powered by the same 4.0-liter flat-six found in the 911 GT3 and the spectacular Cayman GT4 RS. If Porsche’s engineers were trying to squeeze more than 500 horsepower into the lightweight Spyder, you’d be looking at one of the best cars Stuttgart has ever seen.

The prototype lacks the track-ready rear air handling of its Cayman sibling, but is as popular as the Spyder’s ducktail profile, and we’re inclined to believe this will carry over into production. It does come with the wheels and brakes we’d expect to find under the hood of a Spyder — namely a naturally aspirated 4.0-liter flat-six that revs at 9,000 rpm and produces 502 horsepower at 8,400 rpm in the 911 GT3 and Cayman GT4 RS. We expect the Spyder RS ​​to get an output that matches the Cayman GT4, as both will use the same exhaust path, which is slightly more restrictive than the 911.

With the Cayman GT4 RS already in production, we expect we’ll be hearing more about its Boxster sibling before long, although Porsche’s current production queue is lagging behind and there’s a chance we won’t see these in the real world for quite some time. time.
