Boxster vehicle's 2.7L engine power increase over the previous 3.7kW, maximum output power of 180kw, torque is increased to 273N · m; per 100km fuel consumption of 9.3L, compared with a decrease of 0.3L; from accelerates to 100km / h time for the 6.1S, the maximum speed of 258km / h. BoxsterS vehicle engine displacement increased by a 3.2L 3.4L, at 6250r/min Output power is 217kW, an increase over the previous generation engine 11kW, the output torque of 340N · m; from 0km / h acceleration to 100km / h in just 5.4S, faster than the previous generation model 0.1S; maximum speed of 272km / h. Both flat-six cylinder engine is an upgraded version are installed VarioCam valve control system, the system with variable valve timing and valve lift switching (upgrade version) function. Inlet camshaft timing by a 4O. Range of leaf-type regulator to adjust; valve lift switching mechanism on the inlet side of the bucket-type tappets with double-digit, it is driven by an electric hydraulic valves. Bucket-type tappets consists of two lifters, of which one root is located inside the other, two tappets can be driven by a hydraulic pin lock together.
