Its habitat is the track and it is recognized by the many “extreme” aesthetic elements that break a little what is the clean and elegant line of the classic 911 to which one is accustomed. But the result is an aggressive, sporty and aggressive car at the highest levels.
There are two versions available: 911 GT3 and 911 GT3 RS. Before highlighting the technical differences of these two configurations on the mechanical level it should instead be highlighted the aesthetic aspect. The dimensions are 4.56 m in length, 1.85m in width, 1.27 km in height and a weight of 1430 kg.
Porsche 911 GT3 and 911 GT RS: exterior design
The front is the iconic Porsche, with its rounded full led headlights well integrated into the car’s line. On the lower part there are huge air intakes divided into 3 zones, two side and one central (which in turn is divided into 3 parts). A front extractor is also added to improve aerodynamic performance. The bonnet is clean but in the RS version it is made more nervous with two air intakes.
The side cut in the “base” GT3 version is long and sinuous, in the RS one the multiple air intakes both on the rear wheel arch and on the front one steal multiple glances.
At the rear, in both models the enormous spoiler stands out, a distinctive feature of this car, which also makes room to two additional air intakes placed immediately before the rear window. The optical groups are led and developed horizontally. On the lower part of the Porsche in addition to the extractor, we find a central split exhaust and again other air vents.
After this introduction on the aesthetic components, it is easy to understand the intentions of this car dominated by elements recalling the purely running and competitive character.
Unmatched materials and ergonomics
The interiors of the Porsche 911 GT3 and 911 GT3 RS are designed to be a “second skin” on the pilot. On the driver’s side, the dashboard integrates 5 circular instruments, the central one for indicating engine revolutions.
The instrumentation is in color with a 4.6-inch screen allowing you to constantly keep an eye on speed, average fuel consumption, residual autonomy and outside temperature, but also the tire pressure control management and the Chrone Sport chronometer can be recalled.
Added to this is audio reproduction, communications and the map of the navigation system. The “PCM” system (Porsche Communication Management) is the central control unit with a high-resolution touch display and integrated proximity sensor.
It is infotainment that also implements AUS, USB, DVD player, internal hard disk and two SD card readers. Furthermore, with Bluetooth technology, it is possible to connect the smartphone. Also available the “Connect Plus” which offers a SIM card reader with wireless internet connection and which allows access to the car’s network with smartphones, tablets and laptops. There is also the chance to have real-time information on traffic and the fastest route to reach the preset destination.
The interior is dominated by a fundamental material, the Alcantara, but there is also leather and brushed aluminum or silver dye. Alcantara is used in areas where greater maneuverability is required such as the steering wheel rim but also on the selector lever, door handles, armrests, door panels, rear uprights and the cover of the tunnel storage compartment.
The seats are Sportive Plus that guarantee an excellent habitability in sports driving thanks to the raised sides (padded with rigid materials) and to the electric adjustment. The materials used are leather in the side bands, black alcantara in the center and in the headrests (these have embroidered the “GT3” lettering). The 18-way Plus sports seats or the shell-shaped seats made entirely of synthetic material and reinforced with carbon fiber are also available as an option, allowing for a truly remarkable weight reduction. Finally, the seams are also customizable, with contrasting colors (the same dynamic also for the “GT3” inscription on the headrest).
The sound system is a Sound Package Plus with 8 speakers and 150 watts of power, the Bose Surround-System with 12 speakers and a 100-watt subwoofer and a total power of 555 Watts is also available as an option.
Safety is well kept in mind at Porsche especially if in this case we are dealing with high-performance cars destined for frequent use on the track.
The braking system, for example, uses 6-piston calipers at the front and 4-piston calipers at the rear made of a monoblock structure that allows great resistance to deformation and stress. The discs are 380mm with a cast iron structure and self-ventilated geometry, always guaranteeing maximum braking power even in adverse weather conditions.
“Full size” airbags for the driver and passenger are installed in the passenger compartment. The “POSIP” (Porsche Impact Protection System) is also provided, which guarantees safety in the event of a side impact in the door area thanks to two airbags on each side. Other airbags are integrated in the sides of the seats to protect the chest but also in the door panels for head protection thanks to a system that activates them from the bottom upwards.
Finally, the “Clubsport” package is available, which includes a rollbar housed behind the seats, a 6-point safety belt, a fire extinguisher and a predisposition for the battery master switch.
The main differences between the 911 GT3 and 911 GT3 RS can be found on the mechanical aspect:
Porsche 911 GT3
Boxer engine with 6 cylinders and 4 liters naturally aspirated with a maximum power of 500hp, acceleration from 0 to 100km / h in 3.4s and maximum speed of 318 km/h. Rear-wheel drive. The gearbox is a double PDK clutch which in PDK SPORT mode allows much more aggressive gear changes. With the 6-speed GT sports gearbox (optional) the shifts are very short and precise, increasing the driver’s adrenaline and driving pleasure at the same time. The acceleration with the latter goes to 3.9s and the maximum speed to 320km / h.
The maximum torque is reached at 6000 rpm with a value of 460 Nm. The frame is also reworked, improving roll stability, pitching, trajectories and steering precision. Last but not least, comfort has undergone a noticeable improvement, allowing you to be able to carry out more laps in a calm way from a physical point of view. Another aspect is the steering rear axle which allows different steering angles in different speed situations.
It is obtained a system that at low speeds directs the rear wheels to the exact opposite direction of the front ones, allowing a virtual reduction in the wheelbase of the car, at high speeds the system directs the rear wheels in the same direction as the front ones increasing driving stability and agility in lane changes and overtaking. 911 GT3 also features 20-inch alloy wheels in light alloy with central locking (allows faster tire change and a significant reduction in rotating masses). The price starts from 157.580 euros including VAT.
Porsche 911 GT3 RS
Boxer engine with 6 cylinders and 4 liters naturally aspirated with a maximum power of 520hp, acceleration from 0 to 100km/h in 3.2s, top speed of 312 km / h and maximum torque of 470 Nm. Rear-wheel drive. The gearbox is a PDK double clutch with the PDK SPORT function available. This RS goes to the difficult challenge of obtaining the lowest possible “cx” value: air intakes with a titanium grille, an increased spoiler compared to the 911 GT3 and wider side skirts that increase the surface of the underbody are implemented.
The frame consists of an aluminum and steel structure that keeps the weight reduced. The front is developed in polyurethane and carbon fiber. The wheel arches, the bonnet and some elements of the passenger compartment are instead made of a carbon-reinforced synthetic material. The roof is in magnesium, the rear window and the side windows are made of lightweight glass with a weight equal to polyurethane and very resistant to scratches and breaks.
The total weight-power ratio obtained is 2.75kg / cv. Optional is the “Weissach” package which allows for a further weight reduction of 18kg, to which magnesium rims (optional) can be combined, reducing the weight by another 11.5kg. Price starting from 201.378 euros VAT included.
