The entire philosophy of this new car is about reducing dirty air, the major factor that makes it incredibly hard to overtake. And on the current car the hundreds of complex aero surfaces create lots of downforce, but with the bi-product of dirty air. When driving behind another car, your wings no longer work and you have to take different lines and work your tyres harder to keep up. Wind tunnel research says that you can lose as much as 35% of your downforce when following a car within three car lengths, and as you close that up to one car length - you can lose as much as 57%!
