Main problem was front wing endplate airflow management. When they introduce complete new endplates at Nurburgring it was rocketship...
exactly
There were more problems with the 24. Firstly they got the weight distribution wrong. Funny thing was people in here already mentioned their design looked strange, when the car broke cover. Because compared to the other cars it was obvious that mclaren didnt put as much energy moving weight forward with the design they choose. And since all the talk in the technical articles was about how, the teams need move weight forward for 2009, people in here got suspicious something was wrong and it was.
Sec. basicly they got the frontwing wrong. The frontwing is maybe the most important component on the car. It decides how well the diffuser and rearwing works. And they got it wrong. So they needed to create a new frontwing and then adapt the other components to that. Thats what whitmarsh meant when he talked about new aero concept. Especially the endplates needed to be redesigned, as it was obvious, looking at the good teams designs, they got it wrong. For most of the year, even redbull had similar endplates to Mclaren, but they ended up changing them also. If they found the exact reason, why the rearend aero was "turned of" in high speed corners, i dont know but i hope. But the new endplates definitely helped solve that problem a lot. In the end we ended up with a car that was pretty decent. Not the best in high speeds, but a lot better then they started out with. It had good traction i slow sections and good top speed so.
About the discussion in here about Hamiltons input, and if he will have and advantage. All he can do is give input. Until it runs on track he will have no idea of the cars characteristics. Ok he knows the previous Mclaren cars characteristics, which will be an advantage. But he will have no idea how the cars handles before he tries it. And him giving input to the engineers will not change that at all.
