New 2024 Audi A8 will be "very close" to Grandsphere concept

"First class has now shifted to the front row," Audi said, as control of the car is now no longer expressly the preserve of the 'driver'. The front seats are, thus, designed for maximum comfort, with the ability to fold back by up to 60deg, although the expansive interior allows for a near-equally lavish set-up in the rear, where occupants sit on a sofa-style bench with a central armrest. This being a luxury-oriented concept, the air is filtered, temperature controlled and even scented, if required, and each passenger gets a set of speakers that are "inaudible to other passengers". Between the front seats is a cooler with two glasses and a specially designed drinks bottle. 

Notably, and unusually, there are no visible screens, dials or physical controls upon entry into the Grandsphere's cabin, where designers have striven to achieve a "digital detox". On start-up, projections throughout the interior show relevant data and displays to each passenger, while a sensor bar underneath the main front display allows for instant switching between tabs and a rotary-style MMI touch button can be used by the driver to cycle through menus. Eye movements and gestures can be used for the same functions in fully autonomous mode, and because the Grandsphere learns its users' preferences, it can eventually "give personal proposals" to each user.

At 5350mm long, 2000mm wide and with a wheelbase of 3190mm, the Grandsphere is a good deal larger than even the long-wheelbase version of today's A8, but Audi emphasises that it is more a four-door GT car than a traditional saloon, with a sleek silhouette that comes "straight from the wind tunnel". As such, it features a long bonnet despite its electric underpinnings and the rear is heavily streamlined for optimal aerodynamic efficiency. It's unclear how closely related the eventual production car will be, but it will almost certainly lose the outlandish 23in wheels.

The concept uses the PPE platform, developed in partnership with Porsche, who will use it for the new Macan EV coming next year. It has a 120kWh battery capable of charging at speeds of up to 270kW and offering a range of more than 466 miles, and a twin-motor four-wheel-drive powertrain producing 711bhp and 708lb ft. Theoretically, it will do 0-62mph in just over 4.0sec but has a governed top speed to preserve energy.    

Audi admits that "the drive system and the handling are no longer at the top of the design specifications in this new generation of cars", but when Autocar asked if autonomous-capable cars will hold appeal for keen drivers, strategy boss Philipp Gündert said: "We are very focused on giving our passengers and drivers the freedom to choose. This car is focused on autonomous driving but of course we still want to keep that feeling and that close connection."

He highlighted the "monocoque feeling" provided by the steering wheel and seat layout and said an occupant can decide if they want to “enjoy being driven” or still drive themselves. The Grandsphere has rear-axle steering, adaptive dampers and camera-controlled active air suspension, all in the name of conserving some dynamic agility, despite its size. 

Although the Grandsphere majors on premium technology and providing a luxurious experience, its technology will trickle down to smaller cars in the new-era product line-up, potentially with an eye on ride-hailing services and shared mobility solutions.
