Porsche Cayman Gt4
The engine in the coming Porsche 911 GT3 RS will be the heart of the turbocharged engines going into the 2016 911 range coming later this year. It will remain naturally-aspirated in the GT3 models, but get boosted help for every model below those. Elsewhere, the next Boxster and Cayman will get turbocharged four-cylinders, and a V8-powered mid-range Porsche supercar is still in the works.
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.
