About six months after the virtual BMW M4 GT3 made its debut on iRacing the upgrade of the car is due to be launched. This was worked on by Spengler in collaboration with Chris Lerch, the head Vehicle Dynamics Engineer for the simulation platform, and an internal iRacing test driver. The team focussed primarily on working on the driving physics, chassis and optimisations in selected aerodynamic areas. “The aim was to make the handling as similar to that of the real car as possible,” explained Spengler.

The BMW works driver was the perfect point of contact for this as he has already tested the real-world BMW M4 GT3 himself and is also an experienced sim racer who has already brought home countless wins and titles on iRacing. “Bruno’s input was invaluable to this project,“ said Lerch. “His test drives and his feedback advanced the development from start to finish. We are extremely grateful to him for his input.”

“It was a cool challenge bringing sim racing and real-world racing together like this,” summed up Spengler. “The collaboration with iRacing was fantastic and was a lot of fun. From my perspective, the virtual BMW M4 GT3 is now very like the real thing. I’m excited to hear what the sim racers have to say.”

The real-world BMW M4 GT3 is set to make its race debut in the new BMW M Motorsport design next Saturday, in the Nürburgring Endurance Series. The same design is now available to all sim racers on iRacing.
