When I hear the name Cosworth I immediately think of fast Fords and legendary DFV engine used in Formula One across three decades. But obviously times have changed as iRacing and Cosworth partner on a free telemetry system available to all active subscribers.
The multi-year agreement means Cosworth are an official data analysis partner, and their PI Toolbox software will be available to everyone. The software was originally created for real-world racing with detailed real-time comparisons of driver inputs, vehicle behaviour and lap data, and in 2025 it will add live remote telemetry to transmit that information immediately to engineers, teammates and coaches located anywhere.
You’ll even be able to compare your in-sim data with Cosworth-equipped racing cars in the real world, which is going to be fascinating.
“We’re excited to welcome Cosworth as an official data analysis partner of iRacing,” said Tony Gardner, President of iRacing. “Our engineers have asked for more powerful tools to develop race cars and better understand complex performance data – and here Cosworth has risen to the challenge. Together, we’ve created a system that bridges the virtual and physical racing worlds using a single telemetry platform. This is a game-changer for sim racers of all skill levels.”
“This is more than just a partnership – it’s a performance ecosystem,” said Tom Brown, Head of Product and Solutions at Cosworth. “From grassroots esports to professional-level simulation, we’re delivering tools that don’t just replicate the real-world experience – they are the real-world experience. This collaboration enables us to offer the ultimate platform for performance analysis, training and development, supporting both today’s racers and the next generation of drivers and engineers. It’s a powerful step forward that reinforces Cosworth’s role in shaping the future of racing, on and off the track.”
The partnership will be officially unveiled at the iRacing season launch on September 9th, 2025, with the Pi Toolbox access live from September 16th.
And in addition to the Pi Toolbox, there will also be education support with video tutorials and online resources. Cosworth will also have naming rights for various iRacing championships and competitions, including a ‘Cosworth Cup’ series, plus it covers iRacing Studios games, with a new series for iRacing Arcade as well.
All of which sounds extremely cool, as essentially an iRacing subscription will now include a telemetry and data analysis system with custom sim racing templates, and potentially means you could jump straight from being an engineer for a sim team to doing the same job for a real racing outfit.
The only people who might not be happy about the announcement are the various developers of free and paid third party solutions. I’ve used and recommended Garage61, the VRS telemetry logger and more over the years, and I can sympathise if they find their userbase shrinks or disappears depending on how easy the Pi Toolbox is to use.
Looking at the screens shared by iRacing and Cosworth, the data certainly seems comprehensive, if not potentially the most user-friendly initially. But if you’re a sim racer who enjoys in-depth telemetry analysis, it could put you in more demand than ever.
But it’s hard to argue that the partnership is a bad thing for the rest of us – having a free, standard, built-in tool means it’s easier to share data with team-mates and avoids arguments over which system to use, paying for extra subscriptions, etc.
