Building on the success of Resolute, the 2025/26 challenger represents the next evolution of ECU Racing’s design philosophy. Drawing on multiple seasons of competition experience and data-driven refinement, Gwen was engineered with performance, reliability, and manufacturability at its core.

Gwen embodies a holistic approach to vehicle design, with reliability remaining a foundational pillar throughout development, enabling the team to push performance with confidence and consistency.

Designed to set a new benchmark for ECU Racing, Gwen (GW-7) won the IC Class Overall at the FSAE-Australia 2025 competition, and went on to win Formula Student UK 2026 as Australia's first hybrid racecar, featuring a substantial upgrade package transforming it into the GW-7H.
