Porsche has made a return to a flat-six engine for the Cayman! The move comes a few years after the manufacturer went to turbocharged flat-fours. The 2020 Porsche 718 Cayman GT4 has shed its camouflage, and it features a new 4.0-liter naturally-aspirated flat-six engine that pushes out 414 horsepower and 309 lb.-ft of torque.
A classically styled body surrounds the powerplant with a focus on improved downforce and a newly designed “sport exhaust system” which has a deeper tone. But there’s more to the 718 Cayman GT4 than a head-turning exhaust sound.
According to Porsche, both the “2020 Porsche 718 Cayman GT4 and 718 Spyder represent the most powerful and engaging variants of the 718 line-up”. The combination of the shared flat-six powerplant and efficient new exhaust system show how “track-oriented performance” helped inspire the 2020 Cayman and Spyder.
But nothing done with an engine and improved exhaust system matters if you don’t have the transmission and suspension to match.
The 718 Cayman GT4 features a six-speed manual transmission that accelerates from 0 to 60 mph in a breathtaking 4.2 seconds.
The 718 Cayman GT4 and 718 Spyder both are equipped with what Porche terms a “track-bred” Active Suspension Management system. Adaptive dampers and helper springs on the rear axle bring the ride height 1.18 inches (30 mm) lower than a regular 718 Boxster or Cayman. The system also allows for making adjustments to camber, toe, anti-roll bar settings, and ride height.
Porche has included a standard mechanical limited-slip differential with Porsche Torque Vectoring (PTV) system for traction of the specifically designed wheels measuring 245/35 ZR 20 at the front and 295/30 ZR 20 at the rear. Braking comes in the form of a design lifted from the 911 GT3 as standard. It includes cast iron 380 mm rotors. The Porsche Ceramic Composite Brake (PCCB) system, features ceramic composite rotors measuring 410 mm in the front and 390 mm at the rear is optional.
The 718 Cayman GT4 improves overall downforce with an improved aero package that includes a front spoiler lip, a central air outlet ahead of the front luggage compartment lid and new look to the rear diffuser. The design not only frames the highly touted sport exhaust system mentioned above but also reduces lift on the car leading to an increase in downforce of approximately 50 percent compared to the predecessor.
The interior is designed for comfort but also with a nod to the snugness a driver wants in a car meant for the track. The steering wheel measures 14.1 inches (360 mm) in diameter and the shifter is 0.78 inches (20 mm) shorter than on standard 718 models which offer a more seamless feel when changing gears. The modern communication system – you can connect with any device you can think of, is impressive and incorporated into a stylish, clean dash design.
Porsche has hit the mark with the 2020 718 Cayman GT4 which will retail for about $99,200 MSRP, not including fees and taxes. The car is designed to handle everyday driving to high-speed workouts on the track. However, with all of the improvements, and a top track speed of 188 mph, the one feature that may draw the most attention is the sound. Car people love the sound of a highly tuned machine sounding fast even when it’s sitting still.
