By the end of the season and in spite its extensive development programme, "The Device" was never raced. However, the concept was carried over to the Lotus E20's successor, the E21, with the team pledging to continue development throughout the 2013 season. The system was finally raced for the first time at the 2013 British Grand Prix, when it was fitted on Kimi Räikkönen's car; the team opted not to use it on the sister car of Romain Grosjean so as to evaluate its performance relative to the older specification of car.
