The prototype seen here is equipped with the Sports Design package's front bumper and rear diffuser. If the pre-facelift Boxster GTS is anything to go by, these elements should be a close approximation of what we'll see on the production model.

The wealth of testing paraphernalia on the dashboard indicates this vehicle wasn't purchased from a showroom. The prototype also features cross-drilled front brakes with red callipers.

The new GTS is expected to ditch the old model's 243kW/370Nm 3.4-litre horizontally-opposed six-cylinder motor for a version of the 718 Boxster S' 2.5-litre four-cylinder boxer engine.

While the motor in the S produces 257kW of power and 420Nm of torque, the GTS should have a little bit more oomph to its name. Given the facelifted 718 Boxster S is already quicker to 100km/h than the old GTS, a 0-100km/h time around the 4.0 second mark should be no problem.

Standard features should include active suspension, styling modifications, and a snarlier exhaust note. Six-speed manual and seven-speed dual-clutch transmissions are expected to be offered.

The new 718 Boxster GTS will likely make its debut at the 2017 Frankfurt motor show in September.
