Audi Grand Sphere concept to be unveiled on 2 September
Autocar's impressions of what the Grand Sphere could look like
Ingolstadt firm will preview high-tech 'Landjet' machine, due in 2025, at Munich motor show
Audi has signed off the design of the high-tech Project Artemis electric car that will arrive in 2024 as the firm’s new flagship – and will preview it with a concept at the Munich motor show in September.
The Grand Sphere, to be revealed on 2 September, will be one of three show cars that the German brand will produce in the next year to showcase its approach to vehicles equipped with level-four autonomous driving systems (allowing for unsupervised self-driving in certain conditions). The production version will succeed the A8 saloon as Audi’s luxury flagship. It is due to be revealed in 2024, before going on sale early the following year.
Audi design chief Marc Lichte told Autocar that the Grand Sphere will be “a very concrete teaser of the Artemis project” that will showcase “a new revolution in design” with a focus on interior space. He said: “I asked our design teams not for their vision of an A8 successor but for something completely new. [Sales] volumes for three-box saloons such as the A8, BMW 7 Series and Mercedes-Benz S-Class are going down, and there are new, more attractive bodystyles.
“Honestly, I think the S-Class has been a lot more successful than our A8, so we have to come up with something completely new to attack the S-Class. This is the result.”
*Artemis EV design nearing completion*
Initially run as a stand-alone business but recently taken fully in-house, Project Artemis is tasked with developing new platforms and software to underpin a new generation of fully electric, autonomous- ready Audi models.
These will introduce the next major technology step after the latest Audi EVs, such as the E-tron GT and Q4 E-tron.
Project Artemis was charged with developing a long-range grand tourer that would benefit from those autonomous systems, which will initially be available only on a limited number of roads installed with the necessary infrastructure.
The Project Artemis production car, developed under the codename Landjet, was conceived as a successor to the A8 and will serve as a rival to the new Mercedes-Benz EQS electric luxury limousine. The Landjet name is understood to reference the focus on the interior offering 'first-class' luxury similar to a private jet.
Audi considered using the A9 name but has now decided to introduce a new naming convention, due to the new car’s radical differences from traditional saloons and SUVs.
The Landjet will be the first Volkswagen Group model to use the advanced new SSP architecture, which combines elements from the mainstream MEB and performance-focused PPE EV platforms. It will also use an advanced new VW.OS software package developed by Cariad, the Volkswagen Group’s in-house software arm.
It will be one of the first cars to utilise the Volkswagen Group’s unified-cell battery technology, enabling it to offer a range of around 600km (373 miles) on the WLTP test cycle. The Landjet is likely to use an 800V electrical architecture so that it can accept charging rates of up to 350kW from ultra-rapid devices.
Audi has yet to give any further details on the car’s performance or power output.
As with the related Volkswagen Trinity concept, its advanced software will be twinned with a number of sensors and connectivity features to enable advanced autonomous driving.
From its beginning early last year, Project Artemis was run by Alex Hitzinger, a former boss of Porsche’s motorsport programme, but Audi technology chief Oliver Hoffmann assumed control when it was brought in-house.
That move followed reports that Volkswagen Group bosses had concerns about the progress of the project, including that the team was pursuing too many ideas unsuitable for mass production.
*Grand Sphere previews bold new design language for Audi*
Lichte explained that Project Artemis’s focus on autonomy required a radical change in design process, with a focus on the interior design and the exterior then sculpted to fit.
The result of this approach will be seen on the Grand Sphere. Audi has shared preview images showing a car that looks to have a sleek, grand tourer-style silhouette but a large, SUV-esque body section.
Lichte revealed that design work on the concept began three years ago. He said: “We started with a use case around long-distance travelling, and then created a layout that is a revolution for a D-segment car. Because we designed it from the inside out, we designed a huge interior space. From the outside, the Grand Sphere is almost a mono-box volume, but it’s not visible. A mono-box volume is like a van; it’s not sexy. So I came up with some clever ideas that I’m really proud of.
“There are perspectives where the Grand Sphere will look like a classic grand tourer, but when you look, there’s a wide, low windshield to create the maximum interior space.
“When you open the door there’s a huge volume: it’s like going from a 30-square- metre apartment to a loft.”
The Grand Sphere will also showcase the next generation of Audi’s design language, which will feature a greatly reduced use of lines, in part due to the cars’ simplified shapes.
The concept will highlight the “breathtaking proportions” of the final car but will retain a number of recognisable design cues. These include ‘muscle’ lines and Audi’s signature single-frame grille – although the latter will surround a glass housing for ADAS sensors, rather than a traditional engine-cooling grille.
*Radical ‘first class’ interior*
Lichte said that the interior was designed to offer a ‘new living space’, with a focus on allowing occupants to relax when the car runs in autonomous mode. The concept has luxurious seats that can recline to up to 60deg (which Lichte claims exceeds the maximum of any seats in a previous production car) and a large centre console for the front occupants that contains a built-in drinks bar.
“In the A8 and S-Class, there are business-class seats in the second row and in the first row is the driver,” said Lichte. “But in this car there’s the opposite, because the car is the driver. So there’s a lounge in the back, and then the front row is business class. Except it’s not business class any more; we’re now offering first class.”
While the Grand Sphere has been designed around its autonomous capabilities, Lichte insisted that it will retain a driver focus. “It’s an Audi, and an Audi must be a pleasure to drive,” he said.
The concept retains a steering wheel, although this will retract into the dashboard when the car is in autonomous mode. That dashboard will also introduce a radical new design, with the removal of all physical buttons and screens.
“We’re already thinking beyond the screen,” said Lichte. “In this car, there are no displays any more. There’s no dashboard; there’s a huge open space, and we’re working with projection mapping.
“We have some clever ideas on how we will integrate the displays in driving position. There’s a very nice application, and if you need a screen for sat- nav or watching a movie [when the car is] in autonomous mode, we will project all the content onto this application.”
While some of the interior features of the Grand Sphere echo those seen in more conceptual autonomous design proposals, such as its retractable wheel and radical interface, Lichte insisted that “there’s no big gap” between it and the Landjet production car that will be revealed in 2024 and go on sale the year after.
Audi interior design boss Norbert Weber added: "The new leeway afforded to us [by EV design] in the cabin is something we want to utilise to underscore what the exterior design shows. We want to continue to develop the interior with a new expressiveness. We've always had strong interior cabins, and this unique character shows a new importance developing to the inside from the outside."
*Sphere concept trio to explore autonomy*
More Sphere concepts due The Grand Sphere will be joined within the next year by two more concepts that will explore the future design of autonomous-enabled Audi cars, both of which have been previewed in a short video.
Audi exterior design chief Philipp Römers said that the trio would all explore themes around the interior car as a living 'sphere'. He said: "We have the claim 'inside bold, outside magic'. This is the paradigm shift that runs through the different classes. It's not specific to the D-segment, for example, we can also see these concepts radiate into other segments."
The Sky Sphere will be the first of the trio to break cover, and is scheduled to be shown at the Pebble Beach Concours d'Elegance in August. The teaser image suggests it will take the form of a long, two-door coupé that, unusually for an EV, features an elongated bonnet. Audi sales boss Henrik Wenders described it as “a driver’s car and an autonomous car at the same time”.
The Urban Sphere takes a more compact, boxy SUV form, and shows similarities to both autonomous shuttles and Audi’s recent AI:ME electric small SUV concept. Wenders dubbed it “a private space in urban environments".
