We know the next generation of the 718 Cayman will be fully electric when it arrives around mid-decade. In the meantime, the German automaker’s entry-level sports coupe offers a wide selection of engines, from a turbocharged 2.0-litre flat-four to a naturally aspirated 4.0-litre flat-six. Output ranges from 300 horsepower in base trim to nearly 500 horsepower in the case of the Cayman GT4 RS.
