The technological progress in the area of aerodynamics is particularly apparent. It is the first time that a suspended rear wing has been fitted on a Porsche series production car. Its swan-neck mounting is used in a similar form in the GT racing car 911 RSR and the one-make cup racing car 911 GT3 Cup. Since two aluminium brackets now hold the wing element from above, the airflow can pass undisturbed across the underside, which is aerodynamically more sensitive. This new design led to a reduction in the flow losses and not only increased the downforce, but also resulted in well-balanced negative lift conditions together with many other detailed measures. “We developed the aerodynamics of the new 911 GT3 in around 700 simulations. We spent more than 160 hours fine-tuning the car in the wind tunnel,” explains aerodynamics engineer Mathias Roll.
Porsche completes its sports car trio: following on from the Coupé and Cabriolet, the third body variant of the new 911 generation now makes its debut with the all-wheel drive 911 Targa 4 and 911 Targa 4S models. The defining feature of the Targa remains its innovative, fully automatic roof system and, as on the legendary original Targa from 1965, it consists of a wide Targa roll bar, a movable roof section over the front seats and a wraparound rear window. The roof can be conveniently opened and closed in just 19 seconds.It is powered by a six-cylinder, three-litre boxer engine with twin turbochargers: in the 911 Targa 4, it delivers 283 kW (385 PS) and, in combination with the optional Sport Chrono package, facilitates the 0-100 km/h sprint in 4.2 seconds – one tenth faster than before. In the 911 Targa 4S, it boasts 331 kW (450 PS), enabling the new model to reach the 100 km/h mark in just 3.6 seconds under the same conditions – four tenths faster than its predecessor. The top speed of the 911 Targa 4 is 289 km/h (up 2 km/h), while the 4S peaks at 304 km/h (up 3 km/h).
Porsche presented the new-generation 911 Turbo S for unprecedented power, driving dynamics and comfort. The new range-topping 911 is being launched as a Coupé and Cabriolet, both powered by a new 3.8-litre boxer engine with two VTG turbochargers, which delivers 478 kW (650 PS), 51 kW (70 PS) more than its predecessor. Maximum torque is now 800 newton metres (an increase of 50 Nm). The Turbo-specific eight-speed Porsche Doppelkupplung (PDK) cuts the sprint from zero to 100 km/h to 2.7 seconds (0.2 seconds faster), while top speed is unchanged at 330 km/h.The dimensions of the Porsche 911 Turbo S have been increased significantly in line with the enhanced driving dynamics: the body is now 45 millimetres wider above the front axle (1,840 mm), and the overall width is 1,900 mm above the rear axle (an increase of 20 mm). Modified track widths, further developed aerodynamics and the new mixed-size tyres contribute to its agility and sportiness: the track is now 42 mm wider at the front axle and 10 mm wider at the rear axle. The adaptive aerodynamics now include controlled cooling air flaps at the front, while the larger rear wing has been designed for even more downforce. For the first time, the Porsche 911 Turbo S transfers its power to the road with mixed tyres in two different sizes: it has 20-inch tyres with their unique 255/35 dimensions at the front and 21-inch 315/30 tyres at the rear. New equipment options underline the much sportier image of the all-wheel drive 911. These include the Porsche Active Suspension Management (PASM) sports chassis that has been lowered by 10 mm and the sports exhaust system with adjustable flaps that guarantees a distinctive sound.
Six weeks after the Coupe's launch, attention turns to the Porsche 911 Cabriolet. The open-top 911 continues in a decades-long tradition, established when Porsche unveiled the prototype of the first 911 Cabriolet at the International Motor Show (IAA) in Frankfurt in September 1981: customers and fans alike were instantly captivated. The first open-top 911 variant rolled off the production line in 1982, and it has been a constant feature in the model range ever since. The open version of the 911, which marks the start in 2019 of an unprecedented product fireworks display, has all the innovations of the coupe. One of the Cabriolet-specific advanced features is the new hydraulic system which get the roof opened and closed more quickly.The new model echoes the modern lines of the Coupe, though it remains unmistakably a Porsche 911 in Cabriolet form. The fully-automatic soft top has an integrated glass rear window, while the soft top structure contains magnesium surface elements known as bows, which reliably prevent ballooning of the roof at high speeds. The soft top can be opened or closed at speeds up to 50 km/h. New roof hydraulics reduce opening time to around twelve seconds, while an electrically extendable wind deflector ensures that necks are shielded from wind impact.The Porsche 911 Cabriolet is initially available as a Carrera S with rear-wheel drive and Carrera 4S with all-wheel drive. Both rely on a 2,981 cm³ charged six-cylinder boxer engine with 331 kW (450 PS) at 6,500 rpm and 530 Nm torque between 2,300 and 5,000 rpm. The drive efficiency has been increased and emissions reduced by way of an improved injection process; other optimisation measures have also been implemented, such as a new layout for the turbochargers and charge air cooling system. The power is delivered by a newly developed eight-speed dual-clutch transmission. The Carrera S accelerates from zero to 100 km/h in 3.9 seconds (with optional Sport Chrono Package: 3.7 seconds) and can reach speeds up to 306 km/h. The Carrera 4S attains a top speed of 304 km/h and achieves 0-100 km/h in 3.8 seconds (with optional Sport Chrono Package: 3.6 seconds).
The new Porsche 911 GT3 RS is synonymous with precision at the very highest level. This high-performance 911 weighs just 1,430 kilograms and its six-cylinder engine now delivers an output of 383 kW (520 hp). Developed by the Porsche motorsport department based on the 911 GT3 and its racing colleague the GT3 Cup, the RS has a clear focus on delivering optimum race track dynamics. Among the features that help deliver this emphasis are the enhanced four-litre flat engine and the new running-gear setup. The rear-axle steering has been adapted to suit the new tuning and also supports the agile design of the vehicle, while simultaneously enhancing stability. The appearance of the wide, weight-optimised body is dominated by an aerodynamic design with an emphasis on downforce. And despite the strong downforce, the GT3 RS can achieve a top speed of 312 km/h. The large rear wing, like the widened front wings with high-mounted ventilation slits, is made from ultra-lightweight carbon. The interior is also dominated by a racing feel, and the full bucket seats made from carbon provide secure lateral support even when strong lateral forces are present. Lightweight door panels and reduced sound absorption are further illustrations of the consistent lightweight construction.
