Developed in conjunction with Radical’s long-term data partner AiM Technologies, the SR3 XX benefits from an all-new electrical architecture, allowing drivers access to more data and feedback than ever before.

The SR3 XX is the first production race car to feature AiM’s new solid-state technology, which controls not only power management, but also a suite of data options and technology to help Radical drivers be the fastest in the field. It will also be the first car to feature AiM’s new Formula steering wheel technology, akin to those usually seen in high-level single-seaters and Le Mans Prototypes.

The world’s best-selling race car just got smarter thanks to the rollout of new technology
