Porsche takes the new 911 GT3 off the leash. The seventh edition of this high-performance sports car was also developed in close collaboration with Porsche Motorsport. It transfers pure racing technology into a production model even more consistently than ever before: the double wishbone front axle layout and sophisticated aerodynamics with swan neck rear wing and striking diffuser originate from the successful GT race car 911 RSR and the 375 kW (510 PS) four-litre six-cylinder boxer engine is based on the drivetrain of the 911 GT3 R, tried and tested in endurance racing. The acoustically impressive, high-revving engine is also used practically unchanged in the new 911 GT3 Cup. The result is a brilliant driving machine: efficient and emotional, precise and high-performance – perfect for the circuit and superb for everyday use.
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.
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 Carrera Cabriolet offers unfiltered driving pleasure. The fresh-air version of the eighth 911 generation is now being launched just four months after the world premiere of the Coupé. The Cabriolet is a model with particular importance for the sports car manufacturer: this is because the first Porsche sports car, the 356 "No. 1" Roadster from 1948, was an open-top car. Its convertible top was made of simple canvas. Full-featured Cabriolet versions have also enhanced the 911 family since 1982 - and have been equipped with electrically operated high-tech roofs since 1987.The new Porsche 911 Carrera S Cabriolet is equipped with the most technically advanced roof design that Porsche has to offer. The electrohydraulic system is now even lighter and closes the fabric hood in just twelve seconds, and can even do this while driving up to speeds of 50 km/h. The integrated wind deflector also extends electrically in two seconds and calms the air movement in the interior.The new Cabriolet offers pure pleasure even when the top is closed: the squat roofline mirrors the unmistakable silhouette of the Coupé. At the same time, special magnesium panel bows prevent the soft top from ballooning when driving at high speed and also offer optimum protection for the vehicle occupants. The heated glass rear window improves all-round visibility, while the automatic roll-over protection system increases safety. An additional layer made of heat- and noise-insulating material ensures comfort in all weather.
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.
