AERO­DY­NAM­ICS

HWM (Singapore) - - LEARN -

If you caught the first race of the sea­son - the Aus­tralian Grand Prix - you would have no­ticed that the cars looked rad­i­cally dif­fer­ent from last sea­son. This is due to a num­ber of aero­dy­namic reg­u­la­tion changes and the one that is most talked about is the re­duc­tion in nose height. For 2014, the nose must not ex­ceed 185mm from the ground, a re­duc­tion of a whop­ping 365mm, and this has had a dra­matic ef­fect on how the cars look. The rea­sons for this change is pri­mar­ily for safety as the FIA wants to re­duce the dan­gers in in­ci­dents of T-bon­ing and also to pre­vent cars from be­ing launched into the air when the high nose hits the rear wheels of the car in front.

Other cru­cial aero­dy­namic changes for 2014 also in­clude nar­rower front wings, with widths be­ing re­duced from 1,800mm to 1,650mm, thus mak­ing it harder for teams to re­di­rect air to the out­side of the tires. The new For­mula One sea­son will also see shal­lower rear wings and an out­right ban on lower beam wings, which are small wings mounted above the dif­fuser to gen­er­ate low pres­sure and cre­ate more down­force.

Fi­nally, the po­si­tion and num­ber of ex­haust out­lets have also been changed. Cars will now have a sin­gle ex­haust out­let in­stead of two and it must be an­gled up­wards to­wards the rear wing in­stead of down­wards to face the rear dif­fuser. This is to pre­vent teams from blow­ing the hot ex­haust gases over the rear dif­fusers to gen­er­ate more down­force.
