2017 Porsche 718 Engine Explained In Detail

As before, Porsche’s new 718 Boxster initially comes in only two versions: the 300-horsepower base model and the 350-horsepower S. Either can be had with a six-speed manual or a seven-speed dual-clutch (PDK) automatic transmission.

Fifty horsepower is no pittance, but the difference between the base and S-model 718 Boxsters is nothing relative to the vast chasm that separates them, experientially, from their predecessors. The 718’s turbocharged flat-four powerplants, displacing 2.0 and 2.5 liters, respectively, are the headlining changes. Both yield 35 more horsepower than the 2.7- and 3.4-liter naturally aspirated flat-sixes they replace. Torque is the big story, however, increasing by 74 lb-ft on the base car and 43 lb-ft on the S.
