Jean Alesi and Simona de Silvestro were black flagged from the race for not enough speed. Alesi had completed 9 laps, de Silvestro had completed 10. This is a very disappointing finish, because de Silvestro was looking at a good 500, and Alesi came out of retirement from Formula1 to race.
Lotus Engines needs to be completely embarrassed by this turn of events, because they provided sub-par engines to two world class racers in the biggest race in the world. Alesi and de Silvestro had hoped for a power boost to their engines, but they did not get any help.
I hope these two drivers return next year with better engines from a much better engine manufacturer. Lotus needs to apologize for providing them with the auto racing equivalent of a windup toy.
