Could this be the ultimate Porsche 911?Welcome to the new 911 S/T. On the face of things, it looks remarkably similar to the GT3 Touring. No shock, really, as the majority of the bodywork is the same.However, lurking underneath the relatively subdued appearance is the upgraded and outright raucous version of the 4.0-litre naturally-aspirated flat-six found in the track-focused 911 GT3 RS. That’s good for 525hp and 465Nm.Rather than using the PDK gearbox of the RS, the S/T takes the six-speed manual from the regular GT3. It comes with a few tweaks, including a shorter final drive and a single-mass flywheel.Despite using the RS’ track-honed engine, Porsche engineers have tuned the chassis of the S/T to be the ultimate road-focused machine. This includes a simplified suspension setup and the removal of rear-wheel steering.With a price tag of £231,600 and an extremely limited production run, you’d hope this to be a truly special entry into the iconic sports car’s storied history.
