Porsche's RS legacy (Part 2) : The Water Brigade

Following in the footsteps of its famous predecessors, the new model again came in White as its base colour, with the model designation either in Blue or Red.
In its road-going version, this top athlete boasted technical features later to be admired also in the RSR racing version. Just some examples are the wheel bearings in all their features, the split wishbones front and rear, optimised suspension geometry, and a particularly light rear screen made of polycarbonate, as well as the front lid and rear wing produced in carbon.
Displacing 3.6 litres, the fast-revving power unit delivered no less than 381 hp at 7,300 rpm, with maximum engine speed of 8,200 rpm.
A stripped out GT3 with uprated suspension, Cup tyres, half roll-cage and naff decals would become the RS. Actually, Porsche took a baby steps with the GT3 as the very first version of the 996 GT3 did not spawn a RS version.
Only the 996 GT3 ver. 2 included the 'RS', with total production around 682 units.
Revving freely up to very high speeds, the power unit delivered 415 hp at 7,600 rpm from an engine capacity of 3.6 litres – and although these were the same figures as in the “regular” GT3, the RS offered even more outstanding performance, the close-ratio six-speed gearbox with its single-mass flywheel and a reduction in weight by 20 kg or 44 lb enabling the engine to rev up even more spontaneously, accelerating the 911 GT3 RS from a standstill to 100 km/h in just 4.2 seconds and reaching 200 km/h in 13.3 seconds – all the way to the car’s top speed of 310 km/h or 192 mph.
Despite its different body, the RS was 20 kg or 44 lb lighter than the GT3, weighing in at a mere 1,375 kg or 3,031 lb. This reduction in weight was ensured, inter alia, by the use of an adjustable carbon rear wing, a special rear lid made of plastic, and an extra-light syn thetic glass rear window. The power-to-weight ratio provided as a result was an impressive 4.5 kg/kW.
This version reached a production of 1909 cars before the facelift.
Like the latter, the RS power unit now displaces 3.8 instead of 3.6L, delivering even more power and revving up even faster and more dynamically. The engine featured in the new 911 GT3 RS delivers 15 bhp more than its counterpart in the 911 GT3, that is maximum output of 450 horsepower from the fast-revving naturally-aspirated power unit.
This means specific output of more than 118 bhp per litre from the six-cylinder, an extremely high figure for natural-aspiration technology even in the strictest worldwide comparison.
