Overview
The Audi Grandsphere concept is a vision of ultra-luxury electric mobility, designed to redefine premium long-distance travel. Revealed as part of Audi's trilogy of Sphere concept cars, this 5.35-metre-long grand tourer represents the pinnacle of the brand's future. Positioned as a 'private jet for the road', the Grandsphere is built from the inside out, focusing on passenger experience and Level 4 autonomous driving capability. It serves as a direct preview for a future electric flagship model destined to succeed the current Audi A8 limousine in the premium segment.
Key Features
- Level 4 Autonomous Driving: Fully automated capability triggers the steering wheel and pedals to retract into the dashboard and floor, transforming the cockpit.
- Proximity Activation & Gait Recognition: Advanced sensors identify the driver upon approach, automatically opening the reverse-hinged doors and adjusting seating, climate, and ambient lighting preferences before they enter.
- Projected User Interface: Elimination of physical screens in favour of high-resolution digital displays projected directly onto the premium wooden surfaces of the dashboard.
- Premium Touchless Response: Infotainment controls operated via eye-tracking, natural voice commands, and hand gestures that allow interaction even when front seats are fully reclined.
- First-Class Comfort Pods: Independent front seats capable of reclining up to 60 degrees, complete with integrated individual air filtration, scent diffusers, and targeted audio zones in the headrests.
Design & Interior
The exterior of the Audi Grandsphere ditches traditional saloon proportions for a sweeping grand tourer silhouette. Measuring 2 metres wide and just 1.39 metres tall, its dramatic stance is accelerated by a massive 3.19-metre wheelbase. At the front, a flattened, hexagonal Singleframe grille sits behind a transparent cover, featuring lights illuminating it from above. A short front overhang and a windscreen that pushes far forward maximize cabin space, while the top edge of the bonnet flows seamlessly into the side to retain classic grand tourer shape. 23-inch alloy wheels and a sharply tapered, aerodynamic rear end complete the exterior.
Steering away from traditional automotive layouts, the cabin is accessed via rear-hinged doors without a central B-pillar, opening up an uninterrupted view of the 2+2 seating configuration. The interior prioritises a clutter-free environment, using high-quality, sustainable materials such as hornbeam wood veneers, wool, and recycled synthetic textiles. When manual driving mode is disabled, the controls slide out of sight, expanding the space. For connectivity, casting from a phone or tablet transfers to the car's display. The center console also houses an integrated, cooled water dispenser between the front seats to enhance the lounge-like experience.
Other Technical Specifications
Built on the Premium Platform Electric architecture developed jointly with Porsche, the Grandsphere utilizes a dual-motor setup providing permanent quattro AWD. The combined power output stands at 530kW along with a massive 960 Nm of torque. This powertrain is capable of propelling the luxury grand tourer from 0-62 mph in 4.1 seconds. The vehicle is fitted with a 120 kWh battery and advanced 800-volt electrical architecture, supporting fast charging speeds up to 270 kW. This allows the battery to charge from 5% to 80% capacity in 25 minutes, or gain 186 miles of range in 10 minutes. The total projected driving range is estimated at 466 miles.
Production Plans
While the Grandsphere remains a concept show car, Audi has confirmed it is the closest of the Sphere concepts to a viable production vehicle. It serves as the blueprint for an all-electric production limousine, linked to Audi's highly efficient vehicle development. This upcoming production flagship model is likely to be the A8 or A9 e-tron, sitting above the current line-up to replace the combustion-powered A8. Audi intends to launch only fully electric new models globally from 2033, positioning the production variant of this concept as the technological and luxury panicle of their electrification strategy.
