After the Audi skysphere roadster, the German automaker Audi introduced the second member of the sphere trio – a large premium sedan Audi grandsphere (the third Audi urbansphere concept will only be announced next year). The model is the prototype of the next generation Audi A8 and is positioned by the manufacturer as a private “plane for the road”, which, with the comfort of a first-class air flight, will take the passenger from point A to point B.
In unmanned mode (Level 4), all controls, including the steering wheel, pedals and even unnecessary screens are hidden from view, turning the interior into a closed living room-sphere, where passengers can relax as much as possible without being distracted by the traffic situation. The concept does not have a central pillar, and the doors open 90 degrees (while the rear doors are opposite the direction of travel), which allows you to take your place in the cabin as comfortably as possible. Each passenger can get their own climate control settings, lighting and access to the necessary digital services based on projection screens, touch controls, voice and gesture control, and even eye tracking.
The dimensions of the Audi grandsphere are 5350x2000x1390 mm, the wheelbase is 3190 mm, which exceeds the indicators of the current generation of the Audi A8 model. The concept is based on the proprietary platform (PPE) Premium Platform Electric. Separate motors on the front and rear axles with a total power of 530 kW and a torque of 960 Nm, paired with electronics, allow for full-fledged all-wheel drive. As a result, the first 100 km / h takes only four seconds, and the maximum speed is limited for the sake of energy efficiency.
The battery pack for 120 kWh (800 V) is located in the bottom of the electric vehicle between the axles, a full charge is enough for a mileage of 750 km. The battery is capable of charging at 270 kW, which is enough to replenish the 300 km range in just 10 minutes. A typical 5% to 80% charge takes only 25 minutes.
The design and technological solutions of the Audi grandsphere concept will form the basis of future production electric vehicles of the German automaker.
