The 2025 Porsche 718 Cayman is a petrol sports car with RWD and seating for 2. It belongs to the 982 GTS generation. The GTS 4.0 is the version described here, and the figures below refer to that configuration unless noted otherwise.
Performance
The featured GTS 4.0 version develops 400 hp and 420 Nm (310 lb-ft) of torque. Its listed 0-100 km/h time is 4.0 seconds, which is seriously quick. Top speed is listed at 293 km/h (182 mph). Its power output is about 25% below the peer average. Its 0-100 km/h time is about 18% slower than the peer average. The figures establish its straight-line performance on paper, but they do not substitute for measured braking, handling or ride-quality tests.
Fuel economy and range
The listed fuel consumption is 9.9 L/100km. Fuel-tank capacity is 64.0 litres (16.9 US gallons). Recorded CO2 emissions are 225 g/km. Consumption, emissions and range can be measured under different regional procedures, so like-for-like comparisons should use the same market and test cycle.
Dimensions and practicality
Its exterior dimensions are 4,379 mm (172.4 in) in length, 1,801 mm (70.9 in) in width, and 1,280 mm (50.4 in) in height, while the wheelbase measures 2,475 mm (97.4 in). Cargo capacity is listed at 150 litres (5.3 cu ft). The cabin is configured for 2 occupants. Listed curb weight is 1,420 kg (3,131 lb). That cargo volume is about 29% below the peer average. The measurements are useful for comparison, although seat comfort, access and the shape of the load area still need to be judged in person.
In perspective
Compared with nearby petrol sports car models from the same period, the 2025 Porsche 718 Cayman is strongest on price, while cargo capacity and power stand out as the principal numerical compromise. That conclusion is drawn from the recorded specifications rather than a road test. A final choice should also account for local pricing, equipment, comfort and a test drive.
