The 2009 ADHDRC season was the fourth season of the ADHD Rally Championship. It saw the retirement of the Subaru Impreza WRX. This would be the last appearance for the Hurligdon Manor Rally Team. As an act of charity, Warwick Davis entered a specially adapted Lancia Delta. His co-driver was Rowan Atkinson. The crew did impressively well, almost beating Holtz's winning streak on the Rally of Ruislip.
