A few months ago, we reported on some leaked information from an internal presentation for upcoming Porsche models. This included details about the Macan and the 911 Targa, which we now know to be true, but there was also talk about GTS versions of the Cayman and Boxster.

Well, it appears we're now getting our first look at these GTS models, as our spy photographers have just snapped a pair of Porsche prototypes out testing – one Cayman and one Boxster.

Right off the bat, we can see that both GTS-branded cars will get a slightly tweaked exterior with new fascias (bringing LED daytime running lights to the Cayman) and air diffusers at the rear. The true gem of these cars will be the added horsepower to the tune of 340 horsepower – a 15-hp bump. A manual transmission will likely be standard, as will Porsche Active Suspension Management (PASM).

The original leaked information said both cars will debut in April at the Beijing Motor Show before going on sale in June. Prices for both should start around $75,000.
