Audi unveils its Grandsphere self-driving luxury car
The electrically-powered ‘private jet for the road’ is set to replace the A8 as Audi’s flagship sedan
Audi has offered a preview of its luxury-car future with the unveiling of the Grandsphere concept car at this week’s IAA motor show in Munich.
The German carmaker recently announced its intention to stop developing internal-combustion engines by 2026, and the all-electric Grandsphere is likely to go on sale in 2025 as successor to the petrol-powered A8 luxury sedan.
Audi calls the Grandsphere a ‘private jet for the road’, and the car combines a luxurious interior with level 4 automated driving, where the vehicle can handle the majority of driving situations independently, though a human driver can still take control.
At 5.35m car the Grandsphere is longer than the 5.18m Audi A8, and unlike in a conventional sedan, first class has now shifted into the front row. This is because the interior turns into a spacious “sphere of experience” when the car is in self-drive mode: the steering wheel and pedals retract and the front seats become a first class lounge with maximum space and freer views.
The four-seater’s rear doors open backwards and there is no B-pillar to maximise cabin space and airiness.
The lounge-like cabin has a natural-coloured, reduced-design interior. The Grandsphere’s cabin gets a digital detox and the usual screens and dials are absent upon entry into the cabin. When the vehicle comes to life at the touch of a fingertip, the displays take the form of projections on the wooden surfaces under the windshield. The car’s functions can also be controlled touch-free by eye tracking and gesture control.
It’s the second of three “sphere” concept cars from Audi, following the recent unveiling of the electrically powered Skysphere concept roadster that transforms into a self-driving sports car with a variable wheelbase.
These two concept cars — as well as the Audi Urbansphere to be revealed in 2022 — are linked by their ability to drive automatically at level 4, a technology Audi expects to introduce in the second half of the decade.
The infotainment system continues playing content that was on the occupant's portable devices before entering the vehicle.
The roomy interior is housed under a swoopy aerodynamic shape that looks nothing like a traditional sedan. The headlights reference the four rings brand logo and the size of the light areas can be adjusted depending on whether they’re used as daytime running lights or as dynamically staged blinkers — depending on the traffic situation.
Quattro drive is supplied by two electric motors - one at each axle - delivering total outputs of 530kW and 960Nm for a claimed 0-100km/h sprint in just over four seconds.
The range is over 750km depending on the drive mode, and the car can be charged from 5% to 80% in under 25 minutes at fast-charging stations. Ten minutes is enough to charge the battery to a 300km range.
The car rides on adaptive air suspension which provides luxurious waftability but stiffens up for enhanced handling when needed.
