368 kW Porsche 911 GT3 RS and turbocharged 911
A series of leaked documents have revealed the power output of the new Porsche 911 GT3 RS, confirmed the existence of a new entry-level Cayman, and that the 911 will be moving to turbocharged engines.
It has almost been year since Porsche was meant to release its most track-focussed production car, the GT3 RS, but the hard-core car was delayed after the GT3 engine’s much publicised fire hazard. According to the documents, Porsche has managed to wring 368 kW and 460 Nm of torque from the naturally aspirated 4,0-litre engine powering the RS.
Along with the extra power, the GT3 RS will also receive the most radical aerodynamics package of any road-going 911, as well as the wheels and tyres developed for the 918 Spyder.
Given the car’s additional power, it’s assumed that the RS will be able to execute a 0 -100 km/h sprint in between 3,2 – 3,3 seconds, but due to its increased downforce it is unlikely to break the ‘normal’ GT3’s 313 km/h top speed.
But this is minor detail compared to some of the other information the document reveals. Perhaps the biggest news, although already widely predicted, is confirmation that mainstream 911 models will swap their normally aspirated flat-six power plants for turbocharged versions.
The change is rumoured to be scheduled for as soon as the end of the year, with the engine based on a detuned version of GT3 RS unit. The new engines are expected to deliver slightly more power than the current versions, but will offer significant gains in torque, fuel efficiency and CO2 emissions.
The nomenclature of the turbocharged 911 range is unlikely to change, as Porsche has retained the S and Turbo designations for its Macan and Cayenne model ranges as ways to denote power output, and not necessarily engine specifications.
More news is the expected addition of an entry-level Cayman, powered by a new four-cylinder turbocharged unit, with an expected displacement of 2,0 litres. The engine is said to offer sufficient muscle to ensure performance worthy of the Porsche badge.
It also explains why Porsche’s much debated entry-level roadster was finally shelved – the Cayman is still one of the best handling cars on the road, and linked to a smaller, lighter engine with more torque and a more affordable price tag, the result could make for something spectacular.
If the new ‘junior’ Cayman does materialise, one would expect Porsche to offer the same engine in the Boxster, which would end up being the most affordable Porsche in the revised range.
