The Porsche 911 its 50th anniversary in 2013, and is perhaps no better way to begin the than by opening a fresh in the arena of high performance cars with the new 911 GT3.

In the then-new 911 GT3 set the benchmark for road-going cars with the fastest production car lap of the Nürburgring-Nordschleife, and established a for itself as the definitive circuit-bred car. A total of 14,145 GT3 have since been over four generations.

the fifth generation of the 911 GT3 makes its at the Geneva Salon, and is set to take on the position among thoroughbred sports cars with aspirated engines.

The engine, body and chassis are entirely extending the breadth of ability by the previous 911 GT3 by an impressive margin. they ensure that the characteristics of this track-inspired car are preserved, while also more sophisticated day-to-day – not to mention a highly emotional factor’.

The powertrain of the new 911 GT3 comprises a flat engine developing 475 hp kW) at 8,250 rpm, a Porsche (PDK) double-clutch gearbox, and rear-wheel drive.

The six-cylinder is based on that fitted in the 911 S, but shares only a few common All other components, particularly the and valve train, were adapted or developed for the GT3. For Porsche is once again titanium connecting rods to forged pistons.

These modifications set the stage for an extreme engine capable of reaching up to rpm. The dual-clutch gearbox is feature specially developed for the with characteristics inspired by the gearboxes used in motor thus granting the driver benefits when it comes to and dynamics.

The new 911 GT3 is designed for further in precision and lateral dynamics Porsche is using active steering for the first time. on the speed, the system steers in the or the same direction as the front thereby improving agility and

Among the other new driving features are the electronically-controlled, fully rear differential lock, and the engine mounts.

The height, toe and of the newly-developed all-aluminium suspension is adjustable. The new, 20-inch alloy wheels with locking are used for optimal with the road. Traditionally, the 911 GT3 as a two-seater based on the lightweight of the current-generation 911 Carrera. However, the and rear part are always

For this latest generation, the 911 GT3 is 44 wider than a 911 Carrera S the rear axle. Another identifying feature is the large, rear wing. This a decisive contribution to the exemplary of the new 911 GT3, which combines low air with a further increase in lift (downforce).

As a result, the new 911 GT3 again sets fresh performance values. At full from a standstill, 0-62mph is after just 3.5 seconds, and 124 mph in than 12 seconds. The top speed of 195 mph is in seventh (and thus top of the PDK transmission. The lap time on the Nürburgring-Nordschleife is more impressive: the new 911 GT3 completed track, commonly regarded as the difficult in the world, in less 7:30 minutes.

While Porsche is proven around the this credential is particularly for the new model as around 80 per cent of 911 GT3 also drive their on race tracks.

Completely new engine with high-revving

The Porsche Motorsport Department has an new engine for the 911 GT3. This flat-six is a synthesis of the previous GT3 engine, the potential of which had largely exhausted, and the new powertrain of the current 911 Carrera series. For the new engine comes with motor sports characteristics, as dry sump lubrication, a high-revving and forged titanium components.

are combined with cutting-edge of production engines such as petrol injection, demand-controlled oil and lightweight design and materials. The engine weighs around 25 kg than the previous unit, and motor sports performance thanks to a power output of 125 of displacement.

The structural changes to the engine had one principal goal: to the characteristic high-revving concept of the 911 GT3 still. High engine enable high performance changes, whereby the revolutions in the range of maximum power shifting up.

The consistent development made it possible to increase the engine speed to 9,000 enabling the 911 GT3 to reach peak values among street-legal

Valve control by rocker

The foundation for this outstanding is the low moving mass of the crankshaft and train. As with the previous the new 911 GT3 features forged aluminium and forged titanium connecting Forging these highly components means that are particularly strong, and yet lightweight. besides the hollowed valves, the new rocker arm control was a prerequisite for up to very high speed

The low moving masses mean the 911 GT3 engine also has unique dynamics with excellent across the entire rev range.

The of the new development was the cylinder heads, differ fundamentally from of the base engine, and were developed for the 911 GT3. To enable performance and engine speeds, the new heads feature large and exhaust ports, large and separate valve control rocker arm. Cooling and oil are also particularly powerful to for the high loads.

The valve via rocker arms with valve clearance compensation is unique feature. The concept in the 911 GT3 engine originates from and allows very high speeds on the one hand, while the cams with performance-oriented permit large strokes and valve opening times. The of the rocker arm control is mainly in the low masses that allow engine speeds, and the large area between the cam and rocker

As was the case in the previous-generation engine, is once again using the valve control system The continuous angle adjustment of the allows both high and high performance levels, and to the meeting of emissions laws. The adjuster is made of aluminium to weight. Each cylinder is equipped with an integrated for one of the high-pressure pumps of the direct injection system.

Unlike the engine, which is supplied by an high pressure pump, the new 911 GT3 comes with two radially-driven pressure pumps.

First GT3 with direct petrol boosts power, efficiency

For the time, Porsche has opted for a 911 GT3 with direct petrol Compared with the previously conventional manifold injection, technology has proven itself in sports cars, since it higher power and torque, as as yielding higher efficiency and CO2 emissions.

For use in the 911 GT3, this has been developed further, with performance in mind, and a specially developed injection with multi-hole injectors and higher injection pressure. with the swirl injectors of the 911 models, multi-hole injectors a larger usable range of quantity injected. The new GT3 comes six-hole injectors, which sensitive injection with throughputs and high maximum for high engine performance.

The two pumps generate a system of up to 200 bar. This means fuel can be injected, which is sprayed more finely. As the sports car for the race track, a dry oil supply continues to be used for the 911 This meant that the oil pan had to be re-developed. Just like the engine, the high-performance engine is with four suction in the cylinder heads, an extraction in the oil and an oil pressure pump.

The engine of the 911 GT3 has two suction points in the oil pan at the front and so as to be able to safely transfer oil to a oil tank during heavy and braking phases.

Dynamic mounts fitted as standard

The equipment of the new 911 GT3 now includes a more generation of the previously optional engine mounts, which specially tuned. The controller the present 911 GT3 sensors to detect a dynamic driving style, and stiffen the normally elastic mount. For this purpose, the are filled with a sealed containing magnetic particles, changes in viscosity when an field is passed through.

emphasises comfort in everyday on the race track, on the other disturbing mass impulses the engine during cornering and are compensated. Another advantage is the traction when accelerating a standstill.

The intake system of the new 911 GT3 is also a synthesis of high-performance that are based on the basic The air inlet is a specific plenum on the engine lid, which according to the ram-air principle and the air flow across the body for intake manifold pressure. the double-flow air filter, this is by the flow and resistance-optimised air intake which was largely adopted the current-generation 911 Carrera up to the throttle

The plastic resonance intake is also completely new. It is not lighter than the aluminium of the predecessor model, but also with further aerodynamic The induction system principle ensured a fuller torque in the previous model.

This was developed and specifically tuned for the new

As was the case with the predecessor, the new 911 GT3 offers the driver the possibility of the pull of the engine in the mid rev-range at the of a button. When activated, the in the sports exhaust system is reduced, improving gas exchange and increasing the torque between rpm to 4,000 rpm by up to 35 Nm.

Switchable sports exhaust with special exhaust

Naturally, the new 911 GT3 still comes a sports exhaust system, was largely adopted from the model. This means a high-performance system with fan-type exhaust pipes and two is used, which are close to the and integrated into the manifolds. The two front silencers and a common silencer with two central ensure that the 911 GT3 meets the for road use.

Porsche (PDK) with special 911 GT3

The dual-clutch transmission (Porsche — PDK) originates Porsche racing, and with the 911 GT3 it to the racetrack. The motor sports have revised the PDK extensively in terms of mechanics and control for the new car. The resulting transmission the driver with all the essential dynamics of the previous manual complemented with the performance of the dual-clutch transmission.

During track use, it can therefore be much like a sequential gearbox – with even performance and emotional driving

Two modes are available to the driver: shifting or the adaptive shift Manual shifting is achieved two paddles on the steering wheel, the for upshifts and the right-hand for downshifts. shifting travel and optimised force result in even gearshifts with concise similar to the operating characteristics of the 911 GT3 Cup car.

Alternatively, the driver can shift using the selector with a shift pattern on that used in professional sports: shifting up is done by the lever back, shifting by pushing it forward.

Ready for the ‘lightning shifts’ with short reaction and gearshift

Gear-shifting strategy and response of the 911 GT3 PDK have been consistently for maximum performance, and both are different to other Porsche cars. This becomes to the driver during manual in the form of a ‘lightning shift’, permits reaction times of than 100 milliseconds.

To enhance performance, lightning shifts are with a torque overshoot, and the change is conducted with a dynamic adaptation of the engine to the newly selected gear. The times are in a range that was reserved for the world of motor

Paddle-neutral: the de-clutching function of the 911 GT3 PDK

The of a sports car driven to achieve lap times is also determined by the That is why the PDK comes with a feature. If the driver pulls shift paddles simultaneously, the of the PDK are opened, and the flow of power the engine and drive is cut off.

both shift paddles are the clutch engages very if the PSM is switched off. With PSM on, the clutch is closed quickly, but in a pulsed manner.

This offers two principal advantages: the can, for example, neutralise the behaviour of the vehicle when in a wet curve by pulling the paddles, and ‘dip the clutch’ and re-direct cornering force to the wheels of the axle.

The second aspect to individual influence of the driving due to the pulsed onset of the driving when engaging the clutch. to a traditional clutch with a transmission, the rear of the vehicle can be destabilised for dynamic leaning the curve. Furthermore, the driver can use the for accelerating from a standstill.

As is the with manual transmission the driver alone decides on how to using clutch and accelerator without any assistance from and dynamic handling control

Adaptive shifting with strategies

For the first time, the PDK the driver of the new 911 GT3 with the alternative of gear shifts to the adaptive control. In principle, the PDK of the new 911 GT3 only with two switching strategies: and Race Track. This that the gear changes are fast. Gear shifts and points are adapted to the dynamic of the driver.

Race Track mode is by pressing the correspondingly labelled on the centre console. In this the PDK uses shift maps are tailored to the requirements of pure track operation. Gears are longer, and upshifts occur at engine speeds. The race optimisation also entails the shifting programme is still even at a moderately sporting style.

The car is therefore always at the performance-oriented operating points, and traction is available at any time the driver having to shift

Shorter gear ratios

The changes primarily relate to the structure of the PDK. For instance, the use of gears and wheels optimally the engine speed dynamics of the motor. Moreover, the total of the PDK transmission has been reduced by two kilogrammes.

Shorter gear provide completely new characteristics, that the maximum speed is in the seventh and highest gear. In with the rear axle which was shortened by 15 per cent, the new 911 GT3 comes with significantly gear ratios than the ratios of a 911 Carrera models – in all

Even faster lap times: 911 GT3 new rear-wheel steering

Just as as the engine, the chassis of the new 911 GT3 combines the of the previous design with of the current 911 Carrera chassis. The wheelbase and wider track improve the support base, increasing both longitudinal and stability.

All developments had only one in mind, namely to increase the dynamics even further. the new car, the performance package of the 911 GT3 has extended by yet another new feature: rear-wheel steering. The system two electro-mechanical actuators, which are at the left and right side of the axle instead of the conventional arms.

These allow the angle of the rear wheels to be by up to about 1.5 degrees, depending on the

At speeds of up to 31 mph (50 km/h), the system the rear wheels into the direction of the front wheels. The 911 GT3 the curve faster, which more dynamic cornering. The shortening’ of the wheelbase by around 150 also results in significant in agility and everyday usability; the radius is reduced, and manoeuvring and become much easier.

At above 50 mph (80 km/h), the system the rear wheels parallel to the wheels. This results in a virtual wheel extension of 500 millimetres, thereby increasing particularly at high speeds. the side force on the rear triggered by the steering input of the is built up much faster with a non-steered rear which leads to a more and harmonious initiation of the change in

This variability means the rear-wheel steering contributes to resolve the inherent conflict of dynamics between agility and stability. This results in when it comes to agility, safety and practicality, as well as driving performance. The rear-wheel thus played a decisive in the further improvement of lap times at the

Independent all-aluminium chassis by 30 millimetres

The chassis of the new 911 GT3 is a largely new based on the chassis of the 911 Carrera, by 30 mm. The Porsche Active Suspension (PASM) variable damping with two pre-selected specially maps is part of the standard as was the case with the predecessor At the front axle, independent mounts, as well as extended bearings and hubs, provide stability and strength.

The transverse control arm at the front is also a new development that additional stability and reduced

The consistent lightweight design involves to the use of lighter springs and struts with an aluminium tube. These two measures resulted in a weight reduction of three kilogrammes compared to components.

The multi-link rear was also largely developed for the 911 GT3. Again, independent mounts and wheel hubs, as as larger mounts, result in stability and strength. The subframe of the including side panels and arms, are exclusively made a hollow aluminium casting, brings about a weight of around 3.9 kg, as well as increased

The rear axle now also a spring-damper element with a helper spring.

Leaving with more traction: PTV

The rear axle of the new 911 GT3 is equipped Porsche Torque Vectoring (PTV Plus) as standard. The which was adapted specifically for the consists of an electronically-controlled, fully locking rear differential and braking interventions at the rear Together, these features high traction on changing surfaces, an improvement of lateral more precise cornering, and driving stability.

The electro-mechanical system was also modified for the new The use of characteristics specially developed for the 911 GT3 that the direct steering with an appropriate response was in all conditions.

The bespoke wheels the package of measures for a further of driving dynamics. Compared the 19-inch wheels of the previous the current 20-inch GT3 wheels are not one inch bigger, but also an inch wider at the front. The on the front axle are also

The new 911 GT3 therefore rolls on 9 J x 20 wheels 245/35 ZR 20 sports tyres on the axle, and 12 J x 20 wheels with ZR sport tyres on the rear

The wheels are made of forged for the first time, offering low and high strength. Despite larger dimensions, the total of the wheels including special UHP High Performance) tyres is than that of the previous This reduces not only the weight, but also unsprung to enhance driving dynamics.

the wheels come with a locking system, which has optimised further.

Further in braking power

Quintessentially In the new 911 GT3, more dynamic performance goes hand in with further improvements in performance. At the rear axle, brake discs of 380 mm diameter are the ventilation holes of the discs been redesigned, and cooling was by ways of additional brake ducts on the rear axle.

To reduce unsprung weight, the new 911 GT3 the option of racing-derived ceramic brake discs with rings made of cast and aluminium pots, just its predecessor. The two components are still by stainless steel pins.

It comprises of three the continuous horizontal middle element, as well as the lateral before the wheel arches.

All elements have a scoop-shaped, lip, which improves the generated by the front axle.

The identifying feature of the rear of the new 911 GT3 is its cover with fixed The completely newly-developed rear lid is made of a composite material of glass fibre and carbon Wing supports, the large intake for the air supply of the engine, and the lip are all integral components of the design.

The wing is mounted on the supports, remains individually adjustable for use on the track.
