The Cayman is strictly a two-seater because the engine sits where the rear seats would otherwise be. This means that the engine is not quite readily accessible, although there's a way into the oil filler via the boot. Under that long tailgate, is revealed a generous luggage area to supplement the front 911/Boxster-sized boot. Like all other Porsche, the Cayman is not very big, which makes it very practical and usable. And for all its obvious Boxster genes, the Cayman is very much its own car with its curvaceous rear wings and neat fastback roof. As with other Porsches, there's a movable rear spoiler, which deploys above 120km/h.

Going back to were we started, the engine, the Cayman has 3.4 litres, a mix of the cylinder barrels of a 911 with the crankshaft of a Boxster. A 911 engine is of 3.6 or 3.8 liters and a Boxster S has a 3.2-litre engine. It's a strange thing, but even though today's Porsche engines are water-cooled, they still overlay their intake and exhaust notes with a breathy whine like that of the giant air-cooling fans of old.

Basically, the Cayman is a mix and it doesn't have a huge number of new and unique parts. In short, the Cayman is a structure two and a half times stiffer because it's just a Boxster with a roof. In turn, that means that the driving experience becomes much more focused because its suspension can have tauter, sportier setting.

Porsche Cayman reaches a maximum speed of 275 km/h and gets from zero to 100 km/h in 5.3 seconds, even if the fuel thirst is low for such pace. The Cayman is especially good with the optional Porsche Active Suspension Management (PASM), but unlike a 911, it works well enough without it, thanks to a ride that's firm but seldom turbulent. PASM makes the Cayman sit 10mm lower, and in its Sport mode it tautens the damping. And it feels absolutely fantastic when you have the Chrono option (complete with stopwatch for timing your hot laps).

Bottom line, Porsche Cayman is a remarkable illustration of a rigid, solid-roofed bodyshell's advantages. The Cayman S has all the positive Porsche attributes you could want, and none of the snags. It's not the fastest Porsche, not the fiercest, not the most breathtaking. It is a pooling of other Porsche parts, which means that the Cayman is not expensive to develop but it will generate big profits. The new car, by the way, takes its name not from a tax-haven archipelago, but from a type of crocodile.
