Audi Grand Sphere concept to be unveiled on 2 September

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.
