2011 saw Hughes rejoin Team WFR, but this time driving alongside Firth in the new SPEED Euroseries, with the team entering their own WFR WF03-Mugen. It proved a successful venture from the start, with Hughes and Firth winning the first race, and finishing in second in the second race, of the season opener at Paul Ricard. The season finished with Hughes and Firth being crowned champions, beating nearest rival Dean Stirling by three points, having won three races, and taken eight podiums. During the SPEED Euroseries season, he stood in for Ricardo Zonta at Sumo Power GT for two rounds of the FIA GT1 World Championship, partnering Enrique Bernoldi, and finishing fourth and seventh in his two events. Following those two races, Hughes drove for Quifel-ASM at the 2011 24 Hours of Le Mans, driving the now-LMP1 class Zytek 09SC (an evolution of the Ginetta-Zytek used the previous year). Once more, however, he was forced to retire, with the team only able to last for 48 laps before engine failure struck. He also competed in the 6 Hours of Silverstone and 6 Hours of Estoril for RLR Msport, driving their MG EX265 alongside Rob Garofall and Barry Gates, taking fifth in class at both races, resulting in Hughes being classified 16th in the LMP2 category for 2011.
