Lower downforce in cornering will result in understeer or oversteer and the slower you are in a corner the easier it is to handle the effects of these.
With regards to Vettel's performances, the narrative that has come out from a few sources recently is that Vettel is still driving the car as though it was exhaust blown (2013). With exhaust blown diffusers you want to get the power down hard on the exit in order to induce more downforce and speed up the exit of the corner, however with 2014 cars that type of throttle application won't help with "additional" downforce and with massive torque and more limited downforce generally it'll just chew up the tires. Horner himself has commented that, for the first time with the Pirelli's, Vettel is getting through them much more aggressively.
Conversely I wonder if this is where the 2014 rules are playing a little more into Hamilton's abilities - for him the story seems to have turned on it head from eating through the tires to suddenly being able to manage them better than many in the field, at the same time being very fast and having one of the lower fuel usages in the field. Previous interviews have suggested that Hamilton's speed comes from his braking prowess; he brakes later by being able to graduate the brake application less as the car decelerates and scrubs off downforce, hence he's getting close to the maximum between braking and locking the wheels. It might be that his sensitivity and control with his left foot is now being equally applied to his right foot on corner exit, being better able to control the balance between traction and wheelspin with these torque heavy low downforce rules. Could certainly point to why there seems to be both better tire management and low fuel usage from him, while maintaining high speed (relative to his teammate).
Well thats nearly correctTo add to this the fastest way around a track is also the most economical.
Kimi still here, which is unheard of this long after the race, in deep discussion with engineer. He's not happy about that strategy call.
It only takes 1 person in the pit crew taking slightly longer or "making an error" for the stop to have time artificially added to it.So do you guys think some senior Mercedes figure comes to wheel mechanics (mostly British) and tells them - guys, today you have to be slow on Hamilton's car, eg. add 1 to 2 seconds per stop but be quick on Rosberg's car! Clear?
Do you really think no one from the pit crew would spill the beans?
Realistic explanation for slower pit-stops is that Lewes was the one complaining about car handling all the race so pit crew had to do additional front wing adjustments plus I suspect check the floor at the rear and clean rubber from veins.
