The 718 gets a naturally-aspirated flat-six engine mated to a six-speed manual.
After taking the GTS trim level down from the configurator, we knew something big was coming for the Porsche 718 Boxster and Porsche 718 Cayman. As it turns out, we were correct because Porsche has just announced two new trim levels for the 718 lineup. The 718 Cayman GTS 4.0 and the 718 Boxster GTS 4.0 replace the outgoing GTS models, which used a 2.5-liter turbocharged flat-four engine. In its place sits a 4.0-liter naturally-aspirated flat-six engine, which is essentially a detuned version of the one you get in the Spyder and GT4.
This application produces 394 horsepower and 309 lb-ft, which is an increase of 29 hp over the outgoing model and just 20 hp shy of the Spyder and GT4. We thought Porsche might offer a seven-speed PDK transmission in this trim level but the company's press release only makes mention of a six-speed manual. Perhaps a PDK would have made it quicker than the Spyder and GT4.
Porsche says the cars will hit 60 mph in 4.5 seconds when equipped with the six-speed manual and the sports exhaust system on its way to a 182 mph top speed. The GTS 4.0 models also include standard features like Porsche Active Suspension Management (PASM), a millimeter lower ride height, Porsche Torque Vectoring (PTV) with a mechanical limited-slip rear differential, and Sport Chrono package. As with the Spyder and GT4, the GTS 4.0's engine revs to 7,800 rpm and will certainly make a nicer sound than the four-cylinder.
Inside, the GTS 4.0 trim still uses black contrasting design elements with Alcantara material. A Porsche Communication Management (PCM) system with a seven-inch touchscreen comes standard while Bose and Burmester sound systems are available optionally.
Both cars ride on 20-inch light-alloy wheels painted in Satin-Gloss Black wrapped in 235/35 ZR 20 tires at the front and 265/35 ZR 20 tires at the rear. The Porsche Ceramic Composite Brake (PCCB) package is available for greater braking performance. Pricing has only been announced for Germany but expect US prices to start around $87,000 for the Cayman GTS 4.0 and around $100,450 for the Boxster GTS 4.0. Both cars should arrive in the US in late 2020 or early 2021.
