GP21, otherwise known as 'Phoenix', brought PSEM into a new era. It was designed with a focus on lightweight construction and enhanced aerodynamic efficiency. Although its initial design work began in early 2020, the pandemic delayed its debut until September 2022. GP21 has demonstrated significant improvements compared to its predecessors and has also earned recognition with impressive achievements: securing two third-place finishes at the Greenpower races in Aintree and Dunsfold, a 1st place at the Iberian Final in Navarra Circuit, and a 5th place at the 2023 International Final in Goodwood. Some of the newest features implemented include the integration of a robust telemetry system and advanced software development, enabling more efficient data collection and analysis. This valuable capability has helped us acknowledge what works and the areas that require further improvement. The Phoenix proved its longevity in 2024, scoring its best ever result at the first time of asking, with a 2nd place at Aintree.
