Munich. BMW Motorsport SIM Racing presented three spectacular world premieres at its digital BMW SIM Live event, each of which take the transfer of technology between real and virtual racing to a totally new level. The BMW M4 GT3, which is set to become the new flagship in the BMW M Customer Racing range of race cars from 2022, made its debut on the iRacing sim racing platform as a prototype ahead of its first real race outing. The steering wheel in the BMW M4 GT3 has been developed in cooperation with Fanatec and is the first of its kind to work in both a race car and a race simulator. The third global innovation is the concept study of the “Fusion SL” sim lounge furniture. In just a few simple steps, it can be converted from a designer table into a fully-fledged race simulator. With these developments, BMW Motorsport is underlining its aspirations not only to use the event characteristics of sim racing, but also to actively promote the industry through such innovations as the hardware that forms part of its holistic involvement.


“With BMW Motorsport SIM Racing, we are following a 360-degree approach. This means that we have our eye on the big picture,” said Rudolf Dittrich, Head of BMW Motorsport SIM Racing. “We have achieved an awful lot in the first year of our involvement. At the same time, we have also identified great potential and, based on that, have decided to continue to focus strongly on hardware developments in 2021, with which we can promote technical innovations and develop new product categories and markets. With this alignment, we are positioning ourselves in our competitor’s environment in a totally unique way. We really enjoy developing creative solutions and seeing fast results with our process partners, with whom we are developing the world firsts of today and tomorrow.”


BMW M4 GT3 steering wheel, the first of its kind for race car and simulator.

BMW Motorsport has collaborated with sim racing hardware producer, Fanatec, to develop a steering wheel for the BMW M4 GT3 that can be used in both a race car and a race simulator – a technology transfer, the likes of which has never been seen before in motor racing. Absolutely no modifications are required for it to be used in the race car. The carbon steering wheel is a motorsport design, with illuminated buttons and magnetic, dual-action shift paddles also made of carbon. The fact that the hybrid steering wheel perfectly fulfils both roles was demonstrated emphatically by BMW works driver Philipp Eng (AUT) at BMW SIM Live. He entered the stage in the real BMW M4 GT3, emerged holding the steering wheel, inserted it into the simulator, and promptly completed a number of laps in the car’s virtual counterpart. Extensive tests allow the BMW Motorsport engineers to constantly monitor the durability of the steering wheel in real racing situations. It will be available from Fanatec in the first half of 2021.


“The first time I heard of the idea to design the BMW M4 GT3 steering wheel to be compatible with a simulator, I was flabbergasted – because I was thrilled by the concept from the word go,” said Eng. “You have to take your hat off to the pioneering role that BMW Motorsport and Fanatec have taken on here, and to the courage to implement a project of this kind. I know the people who were involved in the development at BMW Motorsport and at Fanatec, and never doubted that they would design a superb steering wheel. Compared to the steering wheel in the BMW M6 GT3, for example, the new wheel has extremely good ergonomics. It is very comfortable to hold. You can tell that real professionals have been at work in every area.”


The BMW M4 GT3 as a prototype on iRacing.

As with the BMW M8 GTE and BMW M4 GT4 before it, BMW Motorsport has worked very closely with popular sim racing platform iRacing over the past few months, in order to integrate the BMW M4 GT3 as faithfully as possible in the simulation. The difference this time is that the car is being used as a test car on iRacing even as it is being developed. As such, the sim racers can follow the development together with BMW Motorsport, and can help drive the development forward until the final version is available on iRacing and to real motor racing customers later in 2021. At the same time as the real car is being developed, BMW Motorsport engineers have provided their colleagues at iRacing with CAD data and photos as a reference, which they can then use as a basis when programming and designing the virtual BMW M4 GT3. In an additional data package, iRacing received all the information on the driving dynamics of the BMW M4 GT3. BMW Motorsport engineers use the same set of data to operate the BMW Motorsport simulator, for example. In total, over 70 GB of data has already been exchanged. The common goal: to recreate the actual driving dynamics as realistically as possible.


Philipp Eng was impressed by how successfully this had been achieved when he took the virtual BMW M4 GT3 for a spin for the first time on the simulator at BMW SIM Live. “I find it extremely cool that the BMW M4 GT3 has been introduced on iRacing parallel to its actual development. After all, I am not only a thoroughbred racing driver, but also a thoroughbred sim racer,” said Eng, who, as an alpha tester for iRacing, plays a role in ensuring that the handling of the BMW M4 GT3 is as close as possible to reality. “iRacing is doing a fabulous job when it comes to being realistic. Just a few years ago, I would never have believed that something like this was possible. iRacing has achieved an incredibly high standard in cooperation with BMW Motorsport. I am very excited to see how good the digital BMW M4 GT3 will be in the end.”


BMW Motorsport, BMW Designworks and Sedus combine functionality and home design in the “Fusion SL” concept furniture .

Sim racing is growing in popularity all over the world. As such, the number of users building comprehensively-equipped rigs at home is also growing. At BMW Motorsport, this raised the question of how to integrate these rigs in everyday life. Together with BMW Designworks and furniture manufacturer Sedus, they have come up with a solution. The concept study is called “Fusion SL” – a unique combination of sim racing rig and lounge furniture. The idea was to develop a piece of furniture that would save space and could be aesthetically integrated into a modern living environment. It can be converted into a rig in just a few simple steps, but which is otherwise folded down to serve as a desk, coffee table or seat, thus making “boost” and “ease” concepts that can be experienced not only in the car, but also in the living room.


To implement the project, the engineering quality of BMW Motorsport, design expertise of Michael Scully and his BMW Designworks team, and the production performance of Sedus – one of the leading full-service providers for office furnishings and workplace concepts – were brought together. “The ‘Fusion SL’ concept combines the best of two worlds,” said Scully. “It is not necessarily intended to replace the high-end sim rigs used by professionals. Our goal was rather to make sim racing and the hardware required attractive for new target groups – and, to be honest, their fellow occupants. It is not easy to strike the right balance between the necessary stability, portability, flat profile, torsional rigidity and a visual impression that will bring the piece of furniture out of the cellar and into the living room, as many of these aspects contradict each other. However, design is all about overcoming these challenges.” Ernst Holzapfel, Head of Marketing at Sedus Stoll AG, added: “The ‘Fusion SL’ concept is the perfect home office for sim racers. The Wooom chair is its perfect partner. One minute you can be relaxing comfortably in it, the next it offers you everything you would expect from a good racing seat, with its sporty seating position and good lateral support, thanks to the padding provided.”

CO2 emission information.

Fuel consumption, CO2 emission figures and power consumption and range were measured using the methods required according to Regulation VO (EC) 2007/715 as amended. They refer to vehicles on the German automotive market. For ranges, the NEDC figures take into account differences in the selected wheel and tyre size, while the WLTP figures take into account the effects of any optional equipment.

All figures have already been calculated based on the new WLTP test cycle. NEDC figures listed have been adjusted to the NEDC measurement method where applicable. WLTP values are used as a basis for the assessment of taxes and other vehicle-related duties which are (also) based on CO2 emissions and, where applicable, for the purposes of vehicle-specific subsidies. Further information on the WLTP and NEDC measurement procedures is also available at

For further details of the official fuel consumption figures and official specific CO2 emissions of new cars, please refer to the “Manual on the fuel consumption, CO2 emissions and power consumption of new cars”, available at sales outlets free of charge, from Deutsche Automobil Treuhand GmbH (DAT), Hellmuth-Hirth-Str. 1, 73760 Ostfildern-Scharnhausen and at
