Porsche has introduced the new 718 Boxster GTS and 718 Cayman GTS, both of which offer higher levels of performance when compared to the current S and base variants.

The mid-engine GTS models are powered by a 2.5 litre turbocharged four-cylinder petrol unit that delivers 365 PS and 430 Nm of torque. For comparisons sake, the uprated engine has 15 PS and 10 Nm more than the 718 S models, and up to 35 PS and 60 Nm more the previous generation 981 GTS models.

Available with a choice of a six-speed manual transmission or a seven-speed Porsche Doppelkupplung (PDK), the 718 GTS models also come standard with the Sport Chrono Package, Porsche Torque Vectoring (PTV) with a mechanical rear differential lock and Porsche Active Suspension Management (PASM), which lowers the body by ten millimetres.

In terms of performance, the GTS models with the PDK will sprint from a rest to 100 km/h in just 4.1 seconds, which is one tenth quicker than the 718 S cars. The top speed for both vehicles is 290 km/h, which is also 5 km/h more.

The GTS cars also get a new Sport Design apron at the front to set itself apart from the regular 718 models, along with black-tinted headlights and taillights. More black elements are seen with the logos, rear apron, 20-inch wheels and centre-mounted tailpipes of the standard sports exhaust system.

On the inside, the GTS cars are fitted with Alcantara sport seats featuring GTS logos embroidered into the headrests. Drivers will also find an Alcantara-wrapped steering wheel and a stopwatch that is part of the standard Sport Chrono Package. The Porsche Track Precision App (PTPA) is also available here, allowing drivers to automatically record, display and analyse driving data on their smartphone.

Prices start at 76,137 euros (RM379,311) for the 718 Cayman GTS, while the 718 Boxster GTS goes for 78,160 euros (RM389,390), and both are available for order now in Germany ahead of a mid-December 2017 rollout.
