 Continuing a theme of his presidency , in 2006 Mosley called for Formula One manufacturers to develop technology relevant to road cars . In recent years , a large proportion of the enormous budget of Formula One has been spent on the development of very powerful , very high @-@ <unk> engines , which some say have little <unk> to road cars . Mosley has announced a 10 @-@ year freeze on the development of engines , which would allow manufacturers to spend more of their budgets on environmentally friendly technology such as the <unk> Energy Recovery System ( <unk> ) introduced in 2009 . In July 2008 , he sent a letter to the Formula One teams , in which he called for the teams to propose future sporting regulations to address specific issues including reduced fuel consumption .
