Porsche 991 GT2 RS
The “Widowmaker” has been spied again,
carrying some serious performance intent – the vented front wheel arches from
the 991 GT3 RS have made it on to the GT2 RS test mule pictured here. Its
predecessor ran 0-96 km/h in 3.5 seconds, with a top speed of 330 km/h – this
new version should comfortably top that.
As the performance flagship for the 911
range, the GT2 RS can be expected to produce nearly 700 hp from a turbocharged
3.8 litre horizontally opposed six-cylinder engine, up from 620 hp produced by
the 3.6 litre force-fed “Mezger” engine in the 997-generation GT2 RS. As is the
nature of turbocharged engines, redline will be considerably lower than the GT3
RS’s 8,800 rpm.
It appears to adopt the centre-locking
wheel design from the naturally aspirated GT3 RS, while the front hood and roof
appear to share that car’s wide recess on those areas; as those components were
made of carbon fibre and magnesium respectively, the GT2 RS can be expected to
adopt these materials in the interests of weight saving, as per the modus
operandi of Porsche’s GT-series cars.
Despite the resurgence of the manual
transmission in recent GT Porsches like the Cayman GT4 and the 911 R, the GT2
RS can be expected to pair its engine with a PDK dual-clutch automatic for
speed, as Porsche expects most of its GT model customers to take their cars to
the track.
When applied on the GT3 RS, Porsche’s GT
division boss Andreas Preuninger said that the wheel arch vents double the
level of downforce achieved compared to doing without them. Worth the
additional trouble, then. Further to that end, the front of the GT2 RS also
gains two pairs of dive planes on the front bumper.
Around the back, the GT2 RS mule appears
to have concealed beneath the camouflage additional vents like on GT2s past,
and the exhausts terminate in separate tailpipe units, as opposed to the
centrally mounted one on the GT3, GT3 RS and 911 R. Last but not least, the
rear wing appears yet to be finished but leaves no doubt about its track-biased
intent.
