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.
