Six AMR-Ones were expected to be built, with Aston Martin Racing participating in several international endurance events in 2011, including the 24 Hours of Le Mans. At the 6 Hours of Castellet, the new AMR-One qualified 5 seconds behind the Pescarolo. In the race things took a downturn and the AMR-One finished way down the order. Further problems continued as they only completed a handful of laps at the Le Mans Test Day and were far slower than the top running LMP1 cars. The poor testing was followed by their withdrawal from the 1000 km Spa in order to continue private testing for Le Mans.
At the 24 Hours of Le Mans, the #009 car retired after only two laps, whilst the #007 car spent four hours in the pit before officially retiring, having driven only four laps. Aston Martin decided to skip the Imola round in favour of developing the car, earning them 3 DNS in 4 races and no points. At the 1000 km of Silverstone, Aston Martin dropped the AMR-One and replaced them with their older but much faster Lola-Aston Martin B09/60.
