2.5-Litre Turbocharged – The Boxster GTS Engine (2017)

Porsche’s 4-cylinder, 2.5-litre turbocharged engine is the heart of the 2018 Porsche 718 Boxster GTS and 2018 Porsche 718 Cayman GTS sports cars.

2.5-Litre Turbocharged Engine

The 2.5-litre, four-cylinder turbo flat engine produces maximum power output of 269 kW (365 hp). So it delivers 11 kW (15 hp) more power than the 718 S models. And up to 26 kW (35 hp) more power than its GTS predecessor with naturally aspirated engine. The maximum torque is 430 Nm in conjunction with PDK, and 420 Nm with a manual transmission.

The increase in performance is made possible thanks to a redeveloped intake duct with greater volume as well as an optimised turbocharger with variable turbine geometry (VTG) and increased boost pressure. Instead of a maximum boost pressure of 1.1 bar as seen in the 718 S, the optimised single turbocharger with VTG and a larger compressor pushes the air into the combustion chambers with a pressure of up to 1.3 bar.

This means that the high torque plateau begins even at a low engine speed of 1,900 rpm and remains at the maximum value all the way to 5,500 rpm with a manual transmission. With the PDK, the maximum torque is available between 1,900 and 5,000 rpm.

The 718 GTS models come as standard with a sports exhaust system. The specially aligned interplay of the engine and exhaust flap control and the automatic intermediate acceleration function makes sure that the engine’s performance is delivered with a pretty nice soundtrack.
