We're all familiar with the succession of numbers that follow the letters GT on a hard-core Porsche 911: the GT1 that was Stuttgart's Le Mans contender in the late 90s, the GT2 that packs turbochargers but without the Turbo's all-wheel drive and excess weight, and the naturally aspirated GT3 that's the enthusiast's choice. But a GT4? That's something new, and exactly what Porsche has in store.
To say that Porsche is big in racing is like saying that Warren Buffett dabbles in mergers and acquisitions. But while it fields the 919 Hybrid at Le Mans and in the FIA World Endurance Championship, the bulk of its racing activities are undertaken by private teams that buy customer racecars from the factory. Those in turn are largely based on the 911, but the latest intel from the motor racing world indicates that Zuffenhausen is planning a more accessible customer race car.
It was just the other day that we first caught wind of Porsche's plans to build a GT4 version of the Cayman, and now we're already looking at spy shots of the vehicle in question undergoing testing at – where else? - the Nürburgring.
The old wisdom when it came to the Porsche lineup was that the Boxster and Cayman needed to be kept in line so as not to encroach on even the lower end of the 911 range. But with the latest versions of the compact roadster and coupe, that logic has gone out the window. Especially with the introduction of the latest GTS models (pictured above). But that's not the end of the story.
