Audi grandsphere concept - luxury sedan with an electric drive system

4 September 2021, 16:08:26

Audi grandsphere concept - luxury sedan with an electric drive systemThe Audi Audi grandsphere concept is a luxury sedan with an electric drive system which will debut at the 2021 IAA Mobility which sets off on Monday, September 6. The 5.35 m (17.6 ft.) long Audi grandsphere sedan combines the luxury of private travel in the greatest of comfort with a comprehensive onboard experience offering. Level 4 automated driving makes new dimensions of freedom possible: in this mode, the interior turns into a spacious sphere of experience without a steering wheel, pedals, or displays. And the front seats become a first-class lounge with maximum space, more open views, and access to all the functions of a holistic digital ecosystem that the Audi grandsphere is integrated into.

As the second of three "sphere" concept cars from the brand with the four rings, the Audi grandsphere has a special place. That is because the technologies and design features assembled in it are expected to turn up again in future Audi series. The Audi grandsphere concept illustrates the brand’s claim that it is becoming a trendsetter at the top of the automotive industry for technological transformation and completely new, holistic mobility offerings.

The technology platform of the Audi grandsphere – what is known as the Premium Platform Electric, or PPE – was conceived exclusively for battery-powered electric drive systems and therefore it takes full advantage of that technology. The key element of PPE is a battery module between the axles that holds around 120 kWh of energy in the grandsphere concept. A flat battery layout is possible because Audi uses the entire vehicle base between the axles.

Nonetheless, the Audi grandsphere does not forego the quattro drive system, which is essential to the brand. That is because the concept car has separate electric motors mounted on the front and rear axles that use electronic coordination to deliver all-wheel drive on demand and execute a perfect balance between driving dynamics and energy efficiency. The Audi grandsphere concept's two electric motors are capable of delivering a total output of 530 kW and a torque of 960 Newton meters.

The heart of the drive system is the 800 volt charging technology. Like the Audi e-tron GT before it, this technology is designed to ensure that the battery can be charged with up to 270 kW in a very short time at fast-charging stations. Just ten minutes are enough to charge the battery to a level sufficient to power the car more than 300 kilometers (186 miles). In less than 25 minutes, you can charge the 120 kWh battery from 5 to 80 percent.

Together with a range of more than 750 kilometers (466 miles) – depending on the selected drive system and power output – the Audi grandsphere concept is unconditionally suitable for long distances. Furthermore, its range and charging speed can keep pace with those of combustion engines, making it the perfect universal car for everyday needs.

In terms of dynamic qualities, the Audi grandsphere concept – as is typical for an electric car – truly outshines its rivals with combustion engines. Thanks to the high torque that is available from the first revolution, acceleration from 0-100 km/h (62 mph) takes just over four seconds; maximum speed is limited in the interest of increased range.

The front wheels are connected via a five-link axle, specially optimized for electric vehicles. In the rear, there is a multi-link axle that, like the front, is made of aluminum. Despite the long wheelbase, the steerable rear wheels provide excellent maneuverability. The luxurious Audi grandsphere concept touring sedan utilizes Audi air suspension – a single chamber system with adaptive dampers. Quite well suited for dynamic driving when necessary it guarantees gentle comfort without noticeable vehicle body movements, under normal conditions.

The reason: the Audi grandsphere concept has active suspension. The high-tech system can separately pull up or push down on each wheel separately in milliseconds via electromechanical actuators. That makes it possible to actively control the state of the chassis and therefore significantly reduce pitching and plunging when accelerating or braking. Thanks to the front camera, which recognizes unevenness, the adjustments happen predictively. The navigation system's topographical data are also used to integrate curve radii, gradients, and inclines into the system's projection.
