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.
The 911 Speedster already caused a sensation when it was presented as a concept vehicle. Now Porsche is putting the open-top two seater into production. The Porsche 911 Speedster combines the aspiration of a puristic, driver-oriented vehicle with motor sports technology suitable for everyday use. The 911 R (2016) and 911 GT3 served as a basis for development. A high-revving 375 kW (510 PS) four-litre naturally aspirated boxer engine delivers an emotive sound experience in the cockpit. The six-speed GT transmission is shifted manually. Visually, the new Speedster establishes a bridge to its own history - to the forebear of all Porsche sports cars, the 356 "No. 1" Roadster from 1948. The limited edition of the new 911 Speedster is also reminiscent of this vehicle. Exactly 1,948 units will be manufactured from mid-2019 at the Porsche plant in Zuffenhausen, Germany.As a concept vehicle, the 911 Speedster celebrated its world premiere in 2018 at the ceremony for the "70 Years of Porsche Sports Cars" anniversary in Zuffenhausen. Other public appearances followed at the Goodwood Festival of Speed, the Rennsport Reunion VI in Laguna Seca, California as well as the Paris Motor Show in October. Numerous Speedster elements that characterise the concept vehicle can now be found in the same or similar design on the series production model.Taking centre stage is the aesthetically shaped convertible top compartment lid with its double-bubble streamliners - a quintessential feature of this sports car type ever since the 911 Speedster from 1988. It is the largest and most complex component to date that Porsche has used in a road model made of a single piece of carbon-fibre reinforced plastic. Two trim elements in the double bubbles make room for the roll-over protection system as need, included in the two-seater as a standard feature just like in the 911 Carrera Cabriolet.
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 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.
The Porsche 911 Turbo has been the quintessential high-performance sports car with everyday usability for the past 45 years. Following the market launch of the 911 Turbo S, the next generation 911 Turbo Coupé and Cabriolet are now being introduced – even more powerful, even faster and even more individual. Thanks to their 427 kW (580 PS) engines, 30 kW (40 PS) more than their predecessors, both model variants dip under the magic three second 0-100 km/h mark with a time of 2.8 seconds (0.2 seconds faster). 750 newton metres of torque (up 40 Nm), now without an overboost time limit, make quick sprints even more spontaneous and effortless. Acceleration, power output and torque of the new 911 Turbo therefore all match those of the previous generation 911 Turbo S. Power transmission is performed by an eight-speed PDK gearbox with a Turbo-specific set-up while its top speed remains unchanged at 320 km/h. Options such as the Sports and Lightweight Design packages, sports chassis and sports exhaust system are available for the 911 Turbo for the first time. As a result, customers will be able to adapt their vehicle even more to their individual tastes.
