Porsche 718 Cayman GT4 RS Manthey

The spec table says the Porsche 718 Cayman GT4 RS Manthey reaches 100 km/h in 3.4 seconds, but the more interesting figure is that it ranks 166th out of 600 cars in acceleration. It is faster than 434 cars in the catalogue, yet its power rank sits at 342nd. The lesson is that headline figures do not tell the full story of where this car belongs.

What separates this 718 is not a single maximum number, but the combination behind those numbers. It is one of only 28 cars in the catalogue that pair a naturally aspirated flat-six with the rear wheels, a configuration that places it in a particularly focused corner of the 600-car collection. The engine layout appears in just 47 catalogue cars, and only 36 combine a flat-six with RWD. That context matters more than the 493 bhp figure alone.

The Porsche 718 Cayman GT4 RS Manthey is a track-focused two seater fixed-head coupé with a 4.0 litre naturally aspirated flat-six producing 493 bhp and 450 Nm. Its performance sits in a broader pattern: the 308 km/h top speed ranks 234th, while the used price of £140,000 ranks 243rd. Those positions show a car that is not defined by chasing the highest number in every category, but by the balance of attributes it brings together.

At £284 per bhp, the ownership proposition sits within a catalogue where price, speed and output tell only part of the story. The car comes from Germany, a country represented by 197 cars in the collection, and it carries the Porsche name from a manufacturer founded in 1931. Within the 65 Porsche cars in the catalogue, the Cayman GT4 RS Manthey occupies a distinct space through its combination of rear-wheel drive, naturally aspirated power and flat-six character.

For a collector building a garage from 600 choices, this is a car that asks for a particular kind of judgement. Its appeal comes from the relationship between its engineering choices and its place in the wider collection, rather than from a claim to dominate every chart. The final decision is personal: whether the garage needs another peak performance figure, or whether it needs the specific character of a naturally aspirated flat-six, rear-wheel-drive track-focused coupé. The Porsche 718 Cayman GT4 RS Manthey is defined by that choice.
