The Cayman 718 engine represents the heart of Porsche’s most engaging sports car, blending refined efficiency with driver-focused performance. This mid-mounted powerplant delivers a balance of accessibility and excitement that has defined the model lineage for decades.
The Evolution of the Flat-Four
Originally introduced with the 987 Cayman, the M97.01 engine was a naturally aspirated 2.7-liter flat-four derived from the Boxster. Its successor, the M97.02 found in the 987.2, increased displacement to 2.9 liters, adding low-end torque and a more linear power band. This evolution laid the groundwork for the modern 718, which honors this heritage with its naming convention.
Modern 2.0-Liter and 2.5-Liter Powerplants
718 Boxster/Cayman Models
Today’s 718 models utilize a pair of turbocharged engines that prioritize responsiveness and efficiency. The base 718 comes equipped with a 2.0-liter turbocharged flat-four producing 300 horsepower. This unit features direct injection and a sophisticated wastegate, providing immediate torque from low RPMs.
For the 718 Cayman GT4 and Spyder, a naturally aspirated 3.6-liter flat-six takes center stage. However, the true performance flagship is the 718 Cayman GT4 RS, which utilizes a specially developed 4.0-liter naturally aspirated flat-six. This high-revving engine, drawing from the 911 GT3, produces an impressive 500 horsepower and is celebrated for its screaming exhaust note and track-focused calibration.
Engineering and Performance Characteristics
The turbocharged 2.0-liter and 2.5-liter engines in the current 718 lineup are masterclasses in packaging. Porsche mounted the turbochargers low on the engine, near the exhaust manifolds, to minimize lag and improve throttle response. The result is a surge of power that feels immediate rather than delayed, keeping the driving experience visceral and connected.
The Driving Experience
What sets the Cayman apart is how the engine integrates with the chassis. The low center of gravity provided by the flat configuration enhances handling, making the car feel planted and precise through corners. The exhaust note, particularly from the naturally aspirated six-cylinder variants, is a symphony of mechanical urgency and combustion that cannot be replicated by alternative propulsion methods.
Inside, the driver is cocooned, with the engine note and sensation feeding directly through the steering wheel and seat. This is not a car that hides its intentions; it communicates constantly, ensuring the driver is an active participant in every maneuver.
