The debate over the use of the Drag Reduction System at this weekend’s Monaco Grand Prix has finally been closed after the FIA decided to ban it in the tunnel section of the track.
However, the system will be allowed anywhere else in practice and qualifying and only, as in all previous races so far this seaqson, down the main straight during the race.
Controversy had arisen following the Spanish Grand Prix last weekend, where despite drivers’ reservations, race director Charlie Whiting had suggested the system could be used at a number of points including the tunnel. The underpass is in fact a difficult right hander, though it is normally taken flat by modern high-downforce F1 cars.
Some drivers might have been tempted to gain time by trying to take the tunnel flat with their wings open, but today matters have been clarified by the sport’s governing body.
