First look at the hot Porsche Cayman and Boxster GTS models, both developing an extra 15bhp

Porsche is about to up the ante with the Boxster and Cayman - our spies have caught higher-performance GTS models winter testing in Germany. Information about both models leaked late last year, but this is our first opportunity to see them in the flesh.

Both the Cayman and Boxster GTS are virtually undisguised and look almost production ready, so an official reveal can't be far away. Noticeable changes for the GTS variants include a redesigned front bumper and the addition of a rear diffuser for added downforce. The Cayman can also be seen fitted with carbon ceramic brakes for the first time.

Mechanically, the Boxster GTS will use the 3.4-litre flat-six engine from the S model, tuned to develop a round 15bhp more bringing the total output up to 330bhp. The Cayman will use a more powerful version of the same engine, with power up from 325bhp to around 340bhp.

Further upgrades are also likely to include 20-inch alloy wheels, Porsche’s PASM (Porsche Active Suspension Management) and a manual gearbox all fitted as standard – a PDK automatic ‘box should be offered as an option.

An image from a Porsche dealer conference leaked online last year, which revealed both models would make their world debuts in April – indicating the New York or Beijing show will be their first point of call. There is no official word on pricing, however, but around a £5,000 premium for both models is likely, with the Boxster and Cayman GTS priced from approximately £53,000 and £55,000 respectively.
