We saw GTS versions of Porsche Boxster and Cayman back in January testing in heavy snow near the Arctic Circle in Sweden.
Porsche has now unveiled both models ahead of their public debut at next month’s Beijing Motor Show.
Based on the S models, the new top of the line Boxster GTS and Cayman GTS get more power, improved performance and revised styling.
Power comes from a 3.4-litre flat six engine that complies with Euro 6 emissions regs and delivers 15bhp more than the S variants. the Boxster GTS packs 325bhp and Cayman GTS 335bhp. Torque is also up by 7 lb-ft and is now at 272 lb-ft in the Boxster GTS and 280 lb-ft in the Cayman GTS.
Sport Chrono package is standard on both models and when fitted with the optional seven-speed dual-clutch auto, the Cayman GTS accelerates from 0-62mph in 4.6 seconds and the Boxster GTS in 4.7 seconds.
When fitted with the standard six-speed the top speed is higher than with the PDK. The Boxster GTS has a top speed of 175mph and Cayman GTS 177mph.
Porsche Active Suspension Management (PASM) is standard, as well as the 20-inch alloy wheels borrowed from the 911 Carrera S.
Visually the new GTS models are distinguished from S models with revised front and rear bumpers and blackened bi-xenon headlights.
Inside, there are sports seats and leather trim as standard, as well as Alcantara elements.
Both new GTS models will arrive at Porsche centres in May with Boxster GTS priced at £52,879, and Cayman GTS at £55,397.
