Featured in slides claimed to be taken from a US dealer meeting in Atlanta, Jalopnik reports the leaked information covers new GTS variants of the Porsche Boxster and Cayman twins, the new 911 Targa and the Macan compact SUV.
Following in the footsteps of 911, Panamera and Cayenne variants, the 2014 Boxster and Cayman GTS models are set to sit above their respective 232kW/360Nm and 239kW/370Nm S models and cost around US$75,000 ($80,000) in North America.
According to the leaked information, standard equipment will include a manual transmission and Porsche Active Suspension Management (PASM) with a dual-clutch PDK automatic transmission and an 11kW power increase optional. A slightly improved 0-100km/h time is also expected.
Signalled for an April 2014 premiere at the Beijing motor show, the GTS pair is also planned to feature Sport Design front and rear bumpers, GTS badging, 20-inch Carrera S wheels and an upgraded steering wheel and leather interior.
A road-biased GTS version of the Cayman was first discussed by chief Porsche 991 engineer Andreas Preuninger in March, when he disclosed the car maker’s plans for a hardcore GT3-style version of the smaller mid-engined sports car.
Previously spied testing in Sweden, the new 911 Targa and Targa S will see the return of the model's iconic rollover hoop that was deleted on both 996 and 997 generations.
Shown in the slides with a completely removed centre panel, the 911 Carrera 4 and 4S-based Targa models are said to employ a "fully automatic roof system to satisfy customer demands for comfort".
Whatever the logistics end up being, the roof mechanism is expected to debut on the car at the Detroit auto show in January.
Available internationally in 2014 following its LA auto show unveiling in November, Porsche's smallest SUV, the Macan, will reportedly be powered by a choice of two turbocharged engines.
The slides indicate a 3.0-litre unit in the Macan S and a 3.6-litre in a Macan Turbo. Likely V6 petrol powerplants tied to seven-speed PDK gearboxes as standard, they are expected to be similar units to those found in the new 309kW/520Nm Panamera S and 4S and 220kW/400Nm base Cayenne.
This also allows Porsche to offer a less powerful, more affordable entry-level Macan to sit below the presentation-listed US$52,000 ($55,500) Macan S and US$75,000 ($80,000) Macan Turbo, potentially powered by an Audi-sourced turbocharged 2.0-litre four-cylinder.
The slides’ validity remains unconfirmed at this stage. Porsche Cars Australia public relations co-ordinator Stephanie Schmidt offered only: "We cannot provide any comments on future models and speculation."
