Porsche has rolled out its PDK dual-clutch transmission to the 718 models that employ the naturally aspirated 4,0-litre six-cylinder boxer engine.
The Boxster and Cayman 718 GTS 4.0 variants, as well as the flagship 718 Spyder and 718 Cayman GT4 derivatives, are now available to order with an automatic transmission. They had, of course, launched in manual guise.
Porsche claims the Spyder and Cayman GT4 accelerate from standstill to 100 km/h in 3,9 seconds when equipped with the PDK gearbox, which is a full 0,5 seconds quicker than the manual versions. Furthermore, these 309 kW models reach 200 km/h in a claimed 13,4 seconds (which is 0,4 seconds faster).
The 294 kW Cayman GTS 4.0 and Boxster GTS 4.0 likewise improve by 0,5 seconds in the 0-100 km/h sprint (taking a claimed 4,0 seconds) when fitted with the PDK, and reach the 200 km/h mark in 13,7 seconds (also 0,4 seconds faster compared with the manual models).
The Zuffenhausen-based firm says the standard Sport Chrono package in the GTS 4.0 models adapts the gear-shift characteristics of the transmission according to the four different driving modes. In Sport mode, Porsche says the PDK “operates with faster gear changes, shifts down earlier with automatic throttle blips, and supports optimal acceleration with later shift points”. Sport Plus mode, meanwhile, “fully exploits” the rev reserves of the naturally aspirated flat six.
Porsche also says the PDK versions of the Spyder and GT4 benefit from “enhancements made to their mechanical locking rear differential”. This, claims the company, has a “positive effect on the longitudinal and lateral dynamics as well as traction, and increases driving pleasure”.
Meanwhile, a model year update for the broader 718 family will soon see Race-Tex material replace Alcantara fabric. In addition, a new Python Green paint finish will be added to the colour range of the GT4 and Spyder, with the latter model also set to become available with 20-inch wheels in Aurum (previously available only for the GT4).
