Porsche 981 Cayman GT4 / Porsche 718 Cayman 2.0
The Porsche 981 Cayman GT4 and the Porsche 718 Cayman 2.0 represent two distinct approaches within Porsche’s mid-engine sports car lineup, each catering to different performance expectations and driving experiences. While both share the iconic Porsche DNA, their engine configurations, power outputs, and track performances highlight their unique characteristics and target audiences.
The 981 Cayman GT4 is powered by a naturally aspirated 3.8-liter flat-six engine producing 385 horsepower and 420 lb-ft of torque, paired with a 6-speed manual gearbox. This setup delivers a classic, visceral driving experience with immediate throttle response and a robust power band. Weighing in at 3,050 lbs, it achieves a 0-60 mph time of 4 seconds and a top speed of 183 mph. Its mechanical simplicity and higher output make it a formidable track weapon, especially on circuits demanding strong mid-range power and precise handling.
In contrast, the 718 Cayman 2.0 features a turbocharged inline-4 engine with 300 horsepower and 380 lb-ft of torque, available with either a 6-speed manual or a 7-speed PDK dual-clutch automatic transmission. Slightly lighter at 2,976 lbs, it reaches 60 mph in 4.9 seconds and tops out at 180 mph. The turbocharged engine offers a different character, emphasizing efficiency and torque delivery at lower RPMs, while the PDK option provides rapid shifts that can aid lap times on technical tracks.
Examining their lap times at Circuit of the Americas (COTA) in the counter-clockwise configuration reveals the 981 Cayman GT4’s clear advantage. With medium modifications and similar tire grip levels, the GT4 clocks a 2:25.740 lap, outperforming the 718 Cayman 2.0’s 2:30.990 by over five seconds. Even with lighter modifications and lower tire grip, the GT4 manages a 2:24.240 lap, underscoring its superior chassis and powertrain combination for this demanding track.
However, the 718 Cayman 2.0 shows competitive pace on shorter, more technical circuits like Hallett Motor Racing Circuit, where it recorded a 1:25.440 lap compared to the GT4’s 1:27.20. This suggests that the lighter weight and turbocharged torque curve, combined with the PDK transmission, can offer advantages in tight, twisty sections where agility and quick gear changes are paramount.
On tracks such as Motorsport Ranch-MSR Cresson and its shorter 1.7-mile CCW variant, the GT4 generally maintains a faster pace, though the 718 Cayman 2.0’s lap times are close, especially when equipped with medium modifications and higher grip tires. The GT4’s naturally aspirated engine and balanced chassis provide consistent performance, while the 718’s turbocharged engine and transmission options allow for adaptability depending on driver preference and track layout.
In summary, the Porsche 981 Cayman GT4 excels as a raw, driver-focused machine with a powerful flat-six engine and sharp handling, making it the superior choice for drivers seeking outright lap time performance and engagement on a variety of circuits. The 718 Cayman 2.0, with its turbocharged engine and modern transmission options, offers a compelling alternative that balances everyday usability with competitive track capability, particularly on tighter, more technical tracks. Both cars embody Porsche’s commitment to precision engineering but cater to different driving styles and performance priorities.
