The subtle body tweaks over the S will be complemented by a bump in power.

The 718 Cayman range only has the standard and S versions for the moment, but the family is all set to grow soon when Porsche will unveil the GTS. Spotted from a close distance undergoing final testing, the hotter version of the coupe was not shy about exhibiting the body changes it’s going through to distance itself from the S.

The front bumper now hosts more prominent air ducts, while at the back we notice a reshaped diffuser hosting the pair of exhaust tips. In addition, the taillights appear to be missing the two red strips and instead adopt a monochromatic look that in this particular case blends nicely with the body’s colour.

Beyond the visual changes, the GTS will also feature larger alloy wheels backed by beefier brakes to match the more powerful engine. While the S version has 350 horsepower from its turbocharged 2.5-litre engine, expect Porsche to massage the four-cylinder engine and squeeze roughly an extra 20 hp for the GTS. Torque is also bound to increase a little bit over the current 310 pound-feet. Rounding out the tweaks will be some suspension upgrades and some chassis tuning to make the new Cayman more nimble around the corners. While the prototype pictured here appears to have a roll cage, don't expect to see that on the production model.

It goes without saying the extra oomph will make the coupe quicker than the current 718 Cayman S, which needs 4.2 seconds to reach 100 kilometres per hour from a standstill when configured with the PDK transmission and Sport Chrono Package. The S version tops out at 285 km/h, so expect the GTS to go beyond that velocity.

Considering the Frankfurt Motor Show will open its doors next month, chances are Porsche will decide to unveil the 718 Cayman S and its droptop Boxster counterpart in the weeks to come. Further down the line, the engineers from Stuttgart will install a flat-six inside what will be the Cayman GT4 RS limited edition rumoured to be blessed with a 4.0-litre developing somewhere in the region of 400 hp.
