The hills of the winelands were filled with the unabashed screeching of the most powerful naturally-aspirated series-production Porsche 911 ever made. I spent a day of thunder in the lizard-green race car for the road.

The lizard brain developed over 100 million years ago and is responsible for our survival. The actions and emotions that spring from the reptilian brain do so automatically, without us having to think about it. It is mostly triggered by sound. While most of the audio around us is dealt with the front part of our brain, the primeval sound of the GT3 RS engine in anger engages the primitive cortex. It’s like the hiss of an ancient predator. A lizard brain sound.
The sportiest Porsche at the moment is still breathing naturally. Its sibling, the 515kW Porsche 911 GT2 RS might be faster (340 instead of 312 km/h top speed), but it is turbo-assisted with less downforce. Hence the glorious noise emitting from the large diameter dual end pipes of the GT3 RS. In order to save weight the engineers at Porsche Motorsport in Weissach reduced the sound absorption in the cockpit, resulting in even more interior aural pleasures. A wellness treatment for the ears of petrolheads.
They could have saved a couple of more grams by leaving the entertainment system out. The engine should be the solo entertainer. Another redundant part in the car is the rearview mirror. As soon as you aim for the horizon in the RS there won’t be anybody close behind you.
But seriously, the developers shed a lot of weight in the newest Porsche RS family member of rear-wheel driven rockets. It weighs just 1430 kilograms. The large rear wing is made of ultra-lightweight carbon. And an optional Weissach package strips even more weight off the ride, almost 30 kilograms. Most of the magnesium parts are then being replaced by carbon. A titanium roll cage sheds 12 kgs alone.
The GT3 RS is the closest to a race car of all street-legal vehicles Porsche has ever built. And that’s regarding power and chassis tuning. The lightweight construction combined with optimum race track dynamics, active suspension, rear axle steering, special race track ABS and road-approved track tyres enables owners of this 911 to not only take part in a race, without any modifications to the car, but winning it. The GT3 RS screams racetrack. Drive it to a course, destroy everyone else and go home in relative comfort – depending on the road surface.
Even parked the car literally takes your breath away. Especially in this almost obscene lizard green. Whether it is the giant rear wing, the enlarged air intakes or the 20inch front and 21inch rear wheels, standing still this Porsche looks fast. So let me just see how fast.
I am grabbing the Alcantara sport steering wheel and climb into the cockpit. The bucket racing seat is hard and has a fixed back rest. Only the leg room can be adjusted. There is a massive roll cage behind me, a racing harness and a fire extinguisher (!). But the car fits like a glove. Everything inside is purist and driver-focused. Man and machine merge into one.
I push the start button and my lizard brain engages. The car is intoxicatingly fast. But as mentioned before made for perfectly surfaced race tracks. The slightest bump in the road and the Porsche jolts like a mechanical bull and I have to hold on tight to the steering wheel. Precision before comfort.
Let’s search for some smooth tarmac. Helshoogte Pass, outside Stellenbosch, is a promising start. Luckily traffic is light and the wide bends are two-laned. Once again I am awestruck by the ballistically quick response of the boxer engine.
The next piece of twisty road is even smoother: Franschhoek Pass. To add to the drama the car is providing me with, mighty clouds glide rapidly over the mountain range. Roaring past the vineyards I picture the ripe grapes getting goose bumps like me. Maybe not so good for wine, but surely great for Grappa.
Luckily all this power and performance comes with a safety net. PSM helps you to survive this frighteningly fast car. Porsche Stability Management assists in tricky situations. Too early on the gas after a tight bend? PSM! Sliding after a sudden downshift? PSM will catch you because it can.
That wasn’t always the case. In analogue times Porsches were just driver cars, without any traction control. I recently had the opportunity to drive one of those legendary widow makers in the cradle of motorkind, in Stuttgart. A 959 from 1986. The most important car Porsche has ever built. In a time when the 911 was about to be replaced by the front-engined 928, the technological marvel 959 showed impressively what a 911 could do. It was years ahead of the competition. The very first hyper car. A limited number were handmade. And they cost Porsche twice as much as the already enormous asking price of $200 000 at the time. Or as the note in the Porsche museum next to the exhibited 959 says: ‘Only 292 cars built – the most expensive promotional gift in company history’.
The 959’s raw power kicked me down the narrow country road – the acceleration is staggering. Famous German rally driver Walter Röhrl described it as one of the best cars he has ever driven. And he added some advice: ‘Don’t go off the gas, when you go around a bend, otherwise the car goes backwards’.
In the meantime I am on my favourite road, Clarence Drive, the R44, between Gordon’s Bay and Rooiels. And as mentioned before the GT3 RS won’t overtake me with its rear end. Thanks to PSM. The road surface is once again perfect and the combination of twisty curves enable some spirited driving.
The enormous downforce of the GT3 RS is responsible for the unbelievable traction. Defying the laws of physics in almost each and every bend. A raw emotional and truly exhilarating experience. My drive wouldn’t be complete without stopping at the end of the private steep road, leading up to the Steenbras Dam gate. It is so Southern France, Corniche de Crête and Rally Monte Carlo. It is also one of only a few mountain roads in South Africa that has a hairpin bend in excess of 180 degrees. And the views from the top are so beautiful, that you might be tempted to finally take your eyes off the green lizard for a second. Could there be a more appropriate ending to an exciting trip in Porsche’s race car for the road?
By the way, just out of interest. Who is going to buy a car that doesn’t leave you with much change after spending R5m? Well, according to Porsche, the typical GT3 RS owner has on average three other cars for day-to-day driving in his garage.
