Why the GT4 Has Earned Its Reputation
In a market flooded with high-performance sports cars, the Porsche 718 Cayman GT4 stands apart through a deliberate focus on driver engagement over outright speed. It isn't the most powerful car in its price bracket — that's precisely the point. Porsche has tuned every system around giving the driver maximum feedback and control.

The Engine: A Naturally Aspirated Jewel
In an era dominated by turbocharged powerplants, the GT4's 4.0-litre flat-six is a rare holdout. The absence of forced induction means a linear power delivery that climbs smoothly all the way to the 8,000 rpm redline. There's no turbo lag to manage, no sudden surge — just a pure, predictable build of power that rewards commitment.
The sound alone justifies a significant portion of the asking price. At full throttle approaching the redline, it produces one of the most characterful engine notes in modern motoring.
Handling and Chassis
The mid-engine layout gives the GT4 a balance that front-engined sports cars struggle to match. Weight distribution is close to ideal, meaning the car rotates willingly on corner entry without feeling nervous. Key chassis highlights include:
- Adaptive PASM suspension — adjustable between road and track modes
- GT3-derived front axle geometry — sharper steering response than the standard Cayman
- Larger brake discs with GT calipers — exceptional feel and fade resistance in extended track sessions
- Michelin Pilot Sport Cup 2 tyres — semi-slick grip levels in dry conditions
On Track: What It's Actually Like
The GT4 rewards precise driving above all else. Carry too much speed into a corner and it will understeer honestly rather than swap ends. Get the braking and turn-in right, and the rear squats and rotates with beautiful predictability. The six-speed manual gearbox has a short, precise throw that makes heel-and-toe downshifts satisfying rather than stressful.
Over a full day of track driving, the brakes remain consistent, the cooling systems keep temperatures in check, and driver fatigue is surprisingly low — the ergonomics of the cockpit were clearly developed with extended driving in mind.
Should You Buy One?
If your priority is lap times per pound spent, there are faster options at the GT4's price point. But if you want a car that teaches you to drive better with every session, one that communicates honestly and rewards skill rather than masking it — the GT4 is in a class of its own. It is, quite simply, one of the most complete driver's tools on sale today.
