If this latest report holds true, the mainstream Porsche 911 range will soon adopt a fully turbocharged engine range in order to deliver both more power and reduced fuel consumption.
Porsche's head of research and development, Wolfgang Hatz, spoke to Autocar about the upcoming Porsche 911 GT3 RS, as well as what's heading down the company's production engine pipeline.
On the soon-to-be-revealed 911 GT3 RS, which our spy photographers nabbed without camouflage back in December, Hatz said that the new car will be "far more extreme" than the previous-generation model and will be the first car to be powered by Porsche's next-generation horizontally opposed six-cylinder engine.
For the 911 GT3 RS, the next-gen motor is expected to generate around 370kW of power without the aid of turbocharging. The current 991-series GT3 has 350kW/440Nm available from its 3.8-litre flat-six.
According to the magazine, Hatz stated that the new flat-six will be available only in turbocharged form when it's dropped into the rest of the 911 range.
A new turbocharged four-cylinder boxer engine, displacing around two litres, will power the mainstream Boxster and Cayman families from early 2016 onwards. This motor will not appear in the flagship 911 range because Hatz and others at Porsche believe that "a 911 has a flat-six engine".
Hatz confirmed that the company will soon launch a GT4 variant (above) of its Cayman coupe, which will feature significantly more power than the 250kW Cayman GTS, but should fall shy of the much rumoured 300kW mark.
Porsche's R&D head also told the British publication that Porsche is working on a supercar that will slot in between the 911 and 918, and which will debut before the end of the decade. If earlier reports about this car are correct, this vehicle will be powered by a new Porsche-developed V8 engine mounted amidships.
