Porsche has dropped the covers off its ultimate naturally aspirated 911 – the GT3 RS 4.0. Set to be the grand finale of the current 911 series, codenamed 997 this street-legal track racer will likely be the final special edition before an all-new model is unveiled at the Frankfurt Motor Show this September.
Limited to just 600 vehicles, there is some serious racing pedigree underpinning the GT3 RS 4.0 with the new model’s boxer engine using a crankshaft lifted straight from the 911 GT3 RSR racing car and the forged pistons’ connecting rods fashioned from titanium. It will be available exclusively with a six-speed sports manual gearbox.
The four-litre displacement sports engine, the biggest 911 model line engine ever, is also the most powerful naturally aspirated engine ever built by Porsche. Maximum power is now 368 kW (500
hp) at 8,250 rpm, that’s 92 kW of power per litre. Maximum torque is 460 Nm at 5,750 rpm.
The 911 GT3 RS 4.0 will offer some stunning performance with a recorded lap time of 7m 27s for the Nürburgring-Nordschleife. That’s 1.7 seconds faster than the Carrera GT and 6 seconds faster than the GT3 RS. So it’s a very serious machine.
In as straight line the GT3 RS 4.0 will sprint to 100 km/h in 3.9 seconds and its racing-inspired gearing takes it to 200 km/h in under 12 seconds. Read the rest of this entry »
