A manual transmission may soon return to the left hand of Porsche GT3 purists following strengthening rumours of an old-school 911 R spin-off.

The $293,200 GT3 and $387,300 GT3 RS are fantastic, blissful machines in 991-generation guise, but controversially they are seven-speed dual-clutch-only for the first time. No manual has irked the purists, if not restricted the sales volumes.

Enter the 911 R. US motoring outlet Car & Driver report that Porsche is preparing a manual transmission version of the GT3, complete with wide-body but smaller wheels and deleted spoiler.

It is likely the 368kW/460Nm 4.0-litre flat six-cylinder engine of the GT3 RS will be used, which in auto guise claims a 3.3-second 0-100km/h – two-tenths faster than the considerably cheaper 350kW/440Nm 3.8-litre flat six in the regular GT3.

A source has confirmed to MOTOR that several Australian buyers have already placed interest in the 911 R, even though it hasn’t officially been announced. It is expected to retail at over $400,000, which makes it more expensive than either GT3 model.

With the 911 Carrera grades now turbo-only, it has ended the coupling of manual transmission with naturally aspirated engine. Porsche engineers are likely to be even more disappointed by that reality than 911 traditionalists – making a fix on the way rather more likely.

Look out for the 911 R at the Geneva motor show in March.
