Car Manufacturers Like Porsche Have High Safety Systems Installed, But
No Amount Of Safety Systems Can Help A Bad Driver
This 911 is the first in the world to feature an innovative system for recognising significant wetness on the road, including the Wet driving programme that can be manually selected at any time.
This program has been specially developed to support the driver in wet conditions. The system uses acoustic sensors in the front wheel housings to recognise sprayed-up splash water, and in this way can detect wetness on the road.
This makes it fundamentally different from windscreen wiper rain sensors, which only react optically to water droplets on the windscreen, independently of the road conditions. The response behaviour of the PSM and PTM systems is preconditioned if a road is recognised as wet. The system informs the driver of the detected wetness and recommends manually switching to Wet mode.
The corresponding function can either be activated in the new button bar above the centre console or is integrated in the mode switch with the optional Sport Chrono Package. If the driver activates this mode, the Porsche Stability Management (PSM), Porsche Traction Management (PTM), aerodynamics, optional Porsche Torque Vectoring (PTV) Plus, and drive responsiveness are adapted to the conditions in such a way as to guarantee the best possible driving stability.
From 90km/h, the rear spoiler is adjusted to maximum downforce, the cooling air flaps open, the accelerator pedal characteristic is flatter, and PSM Off or Sport mode can no longer be activated.
New brake system setup with optimised brake response
The wheel sizes with further-developed tyres led to a completely new chassis setup. This resulted in renewed improvements in wet grip and dry handling as well as in rolling resistance.
The spring and anti-roll bar rates are higher and the brake system operates more precisely. Because the new rear wheels can transmit a higher braking force, the diameter of the rear brake discs has been increased from 330 millimetres to 350 millimetres. The brake pedal ratio has been shortened.
The pedal is now made of an organic sheet composite material consisting of steel, carbon fibre and plastics. It weighs around 300 grams less than the previous steel component. There is a more immediate brake response, and the driver can also feel a very precise pressure point because of the firm connection.
Sporty drivers in particular will value this optimised feedback. The brake system modifications are rounded off by the change from a pneumatic brake booster to an electric booster.
Direct steering ratio for greater agility
In order to further increase the agility and dynamic turn-in behaviour of the new 911, the steering ratio is around 11% more direct on the standard sports cars and approximately 6% more direct on vehicles with optional rear-axle steering.
This 911 is even more agile as a result and provides even greater driving pleasure on winding roads. A new, typically Porsche steering controller is also used for improved feedback on the steering wheel. Thanks to the enhanced algorithm, the road conditions – dry, wet or snow – can be better taken into account to achieve the desired handling.
The comfort-oriented Power Steering Plus is optionally available. At low speeds, this steering operates with an adapted steering support, enabling particularly easy manoeuvring and parking.
