If the Cayman's at it, so will be the Boxster. Porsche is rolling out the same GTS performance package to its open-air roadster as it is offering on the closed Cayman coupé. Well, nearly. You see, the Cayman is designed to be a little more hardcore than a Boxster, a bit more of a focused driver's car. So while the Boxster gets the same 15hp increase in power and 10Nm increase in torque as the Cayman, it's starting from a lower base. That means the Boxster GTS develops 330hp (compared to the Cayman GTS' 340hp) and 370Nm of torque (380Nm for the Cayman).
That makes the Boxster GTS 0.1 seconds slower to hit 100km/h from rest compared to the Cayman, with a time of 4.7 seconds. That's helped by the standard-fit Porsche Active Suspension Management (PASM) and Chrono Sport Pack, which brings with it launch control. You also have to spec the car with the PDK paddle-shift gearbox to get the fastest possible 0-100km/h time.
It helps to have the PDK from a fuel consumption point of view too. It gains you a full 3mpg compared to a Boxster GTS fitted with a manual gearbox, clocking in at 34mpg.
As with the Cayman, the Boxster GTS is distinguished by black 20-inch wheels with 235/35 (front) and 265/35 (rear) tyres, a subtle aero kit and a leather and Alcantara interior. You can also have an optional Sports Chassis that drops the car by a further 20mm, but Porsche claims that with the clever electronics of the PASM, the GTS is still comfortable and refined on a long journey.
Anything else?
Porsche claims that both of the new GTS models can trace their lineage right back to the original 904 GTS race car (which won the Targa Florio amongst others) of 1963. That's a lineage claim that would be a lot easier to believe if the hulking Cayenne GTS weren't in there somewhere too...
