The Porsche 911 GT3 is still a strong enthusiast choice in the 911 range, and the GT3 RS has gone more hardcore. But both versions are PDK-only. The upcoming Porsche 911 R, spied undergoing testing in Germany, is tipped to adopt the naturally aspirated engine from the aforementioned GT3, producing somewhere in the neighborhood of 475-500 horsepower. Only instead of an automated dual-clutch transmission, it'll feature a proper manual.

Other changes are expected in the form of skinnier tires to provide less grip but a more approachable limit of adhesion. It may or may not feature a small ducktail spoiler at the back. We wouldn't be surprised to see it ditch the four-wheel steering system, either. Weissach may also give it some retro cues as well, but the question all those purists will be asking is how many Porsche will make. The last 911 R yielded only 22 examples way back in 1967. This time they'll have to make far more, but we wouldn't expect this particular version to be exactly what you might call "ubiquitous." No matter how rare, it'll definitely be the purist's choice.
