A new generation of porsche 911 was officially launched at the los angeles car show on 28 november 2018, with the roll-out of the later carreras and the four-way carrera 4s models。
The 8th-generation model continues with the unique motion and porsche unique design gene, with a more powerful appearance. As the core of the porsche brand, the 911 model has always been a pronoun for the dream of racing cars and the best interpretation of the porsche principle, taking into account the sporting and daily practicality of the course. Today, porsche 911 officially entered the eighth generation, with the new model code “992” and “992” being its latest chassis age number. The new carreras model code of 992 is used together below。
While the appearance of 992 did not appear to have changed significantly, the structure of the car itself had undergone considerable adjustments. In order to withstand loads under the state of limits and control the weight of the vehicle, high-strength steel has been used in key stressors such as the frame, door frame and so forth, effectively resisting most body distortion. Outside key areas, porsche has significantly reduced the use of pure steel from 63 per cent to 30 per cent. The outer body is heavily aluminum-based and the door is fully aluminium-based, effectively reducing the weight of the white body. In addition, the porsche has enhanced the processing of sections such as the threshold floor, while parts such as the front and back shock-mitigating towers, the back and back arms, the side racks, etc., have also been heavily used for casting aluminium parts。
The appearance of 992 is also not static and the width of the bridge is widened。
Its wind resistance factor of 0. 29 was also re-engineered in parts such as transformable gas grids, motor caps, and even in order to further reduce wind resistance, even the mantra became electric ejection. And there's a retrospect of 992. The mid-deep hood, round headlights, and back-stretch-style radiator designs are another tribute to the classic first generation of 911 (901)。
The tail part of 992 has also undergone significant adjustments: all of the 911 family models of the new generation have a uniform tail width and highlight the fine line in the middle of the tail. Such a significantly wider tail is supplemented by modulated tail-disturbing panels, as well as a nuanced light belt, which adds to the new 911 offensive and sporting breath. The 992 is equipped with the largest lift-down tail wings in history, not only more dynamic visual effects but also aerodynamic efficiencies。
The following is a detailed account of the excellence of 992 in aerodynamic performance:
Maximum cooling while minimizing air resistance while driving。
Compressed air cooling capacity has been further improved compared to the previous generation。
The new integrated tailings are more “original”, which rises not only in a larger area, but also with a dual function of heat dispersion for the cold. Up to the maximum opening angle, the visual effect is more like the second generation of duck tail-forming 911 (930/964), while the area of effective exposure through air flows is as high as 45 per cent. New lift-down wings provide three angles of lift-down depending on the mode of driving or speed of the vehicle, with a small rise of more than 90 km/hour and a balanced flow through the tail。
More than 150 km/hour will be fully raised, thereby increasing high-speed downward pressure and stable driving performance. However, when low-speed travel occurs, the system detects high air temperatures after increased pressure, as long as the speed of the vehicle reaches 60 km/hour, the same tailing will automatically rise and force wind cooling for the medium chiller。
At 70km/h, the entry grid was completely closed to reduce air resistance
Below 90 km/h of the tail wing (post-disturbing fluid) is in a energy-efficient mode and can reduce air resistance。
The entry grid is open at 170 km/h, and the disturbance panels continue to rise and enter the track mode, thereby optimizing driving aerodynamic performance。
Compared to the generation of 911 (991), a new engine with greater power and wider rotations has made the car more fast and steady in the bends, and a more mobile rectification school has also made it harder to drive, and the above-mentioned optimisations have resulted in the official 7 minutes and 25 seconds of new zealand, which is now four seconds faster than the previous generation。
When the road is extremely wet, it is flexible to adjust the driving pattern to the "wet-sliding" mode to enhance aerodynamic performance in rain conditions。
If an emergency requires an emergency brake avoidance, the tarp is raised at high speed (170 km/h) to reduce brake distance by rapidly increasing downward pressure。
In order to optimize the control of vehicle movements to achieve high driving stability, the wet-sliding pattern reduces abs action thresholds, stability and towing control. The wet slide model also adjusts the responsiveness of power transmission systems to ensure greater stability at acceleration。
Under the wet-sliding model, the four-drive system allocates different rectangular output to the front wheel to ensure better pull and more stable acceleration. At the same time, the wet-sliding pattern reduces the locking of the rear differential to enhance driving stability。
Under the wet-sliding mode, the grid is fully opened, and the back-disturbing stream is extended to the track mode to optimize the aerodynamic balance and drive stability。
These improvements have led to a new generation of 911 performance in aerodynamics, and the new porsche 911 once again defined a new age's reference to high standards。
