As in their S variants, Cayman GTS and Boxster GTS feature mid-mounted 3.4-litre horizontally opposed six-cylinder engines, which each see bumps of 15 horsepower and 7 pound-feet of torque, bringing the Boxster to 330hp and 273lb-ft and the Cayman to 340hp and 280lb-ft. With the optional PDK dual-clutch automatic transmission, the Boxster GTS will sprint from zero to 60mph in 4.4 seconds; the Cayman GTS will make the trip in and 4.3sec. Top speed for the Boxster GTS is 174mph with the standard six-speed manual transmission; the Cayman GTS is good for 177mph. It perhaps bears mention that Porsche's standard 911 Carrera takes 4.5sec to reach 60mph (with the PDK) and will press on to a top speed of "only" 173mph (manual).
The new GTS models announce their performance intent with unique front and rear fasciae, blacked-out bi-xenon headlamps, a sport exhaust system with black tailpipes and 20in Carrera S wheels with 235/35-series front and 265/35-series rear tires. The cockpits get the full Alcantara treatment and standard Sport Seats Plus.
In the US, the Boxster GTS starts at $74,495; the Cayman GTS commands $76,195, inclusive of $995 destination charges. Both models commence delivery this summer.
