To make a believer out of everyone of us, a video of the braking prowess of the Porsche 911 GT3 RS 4.0 was released by Sport Auto, the Premiere German performance test magazine. It had set a new braking performance record for road cars during the annual Sport Auto high-speed performance 0-300-0 test event for series models in Papenburg, Germany.
The video shows the 911 GT3 RS 4.0 moving at 300 km/h (186 mph) then getting to zero in just 6.5 seconds without crashing.
It surpassed the world record previously set by the Koenigsegg Agera R, which can go from 300 to 0 km/h time in 6.66 seconds. The other models that took the test include the Bugatti Veyron Super Sport, McLaren MP4-12C, Jaguar XKR-S, Cadillac CTS-V Coupe, Alpina B5 Biturbo, Bentley Continental GT. Only 600 units of the Porsche 911 GT3 RS 4.0 were built. It is powered by a naturally-aspirated 4.0-liter engine. This is the largest engine that has ever been used in a Porsche 911.
This results to an hp/liter figure of about 125 hp/liter (92 kW) and 368 hp/ton. It gives a total output of 500 PS (368 kW / 493 hp) and a torque rating of 460 Nm (339 lb-ft).
With a weight of only 1,360 kilograms (2998 lbs), sprinting from 0 to 100 km/h (62 mph) takes only 3.6 seconds (according to Sport Auto). The GT3 RS 4.0 is capable of running the Nürburgring-Nordschleife track in 7:27 minutes. If you want to see the full test results, buy a copy of the November issue of Sport Auto.
The Porsche 911 GT3 RS 4.0 is indeed a sports car designed and developed to deliver unyielding driving dynamics. In line with this, Porsche specified the high performance sports car with dynamic engine mounts, a chassis tuned for performance as well as with the Porsche Active Suspension Management (PASM). PASM is a sporty version of the Porsche Stability Management (PSM) system that could be deactivated in two phases.
Its particularly light and athletically precise chassis features wheel-bearing components made from lightweight aluminum. Further weights savings are also achieved by employing an increased coil pitch, front axle spring setting and "helper springs" on the rear axle.
Since these components are placed towards the bottom of the spring element, a short and light main spring could be employed while ensuring that the initial tension of the main spring remains in a fully rebound state.
This configuration is typical in motorsport and is even used in all Porsche 911 GT racing cars. Meanwhile, Porsche fitted ball joints on the lower wishbones, tie rods and the tie bar connections on the body as well as the spring strut on the wheel carrier as they are more precise than conventional normal elasto-kinematic bearings.
Astonishingly, users could customize the vehicle height, the stabilizers and the spring system of the new 911 GT3 RS 4.0 to attain certain handling characteristics on racing circuits as desired.
Both the front and rear axle track widths of the new 911 GT3 RS 4.0 have been increased to ensure even faster cornering speeds and more agile steering characteristics.
In addition, the wheels (nine inches on the front and 12 inches on the rear) of the new 911 GT3 RS 4.0 come with central locking and are wrapped in high lateral adhesion tires (sizes 245/35 ZR 19 and 325/30 ZR 19) for high traction and transverse force potential, thereby ensuring greater performance in racing circuits. Offered as standard is a tire pressure monitoring system (TPMS) that consistently monitors air pressure in all four tires.
