Hamilton Vs Rosberg 2014

[MercedesAMGSpy]

Hamilton would be well advised to handle this spat carefully while Alonso seems to be looking to jump ship. It's a pretty well informed assumption that the team will be more likely to side with Rosberg if things got really bad..(having been with them longer and also being German). I don't think anyone down the padock will be hard pressed to replace Hamilton with Alonso.

I think they appreciate Lewis believed in the team before 2014, now it's easy to want to move to Mercedes. Lewis did something a lot of people/ex-drivers told him not to do.

Hamilton has always been known as a late breaker, and I still think what he's doing better than Nico. If I understand the The "break by wire" systems, the harder the driver breaks the more breaking force KERS Generates.

Another way to think of it is that if the driver is using 50% of the breaks, KERS might be 35% and the other 15% is coming from the actual breaks. If the driver is using 100% of the breaks KERS might be 85% and the other 15% is coming from the actual breaks. Thus drivers that break later (harder), can recover more energy with the caveat, that they can control the car under heaver breaking.

If you break later you might be coasting longer as well. This would increase fuel saving as well.

there is only X amount of energy to recover. Braking later doesn't make more of it. It shortens the duration of the KERS recovery and most likely lowering its efficiency as the current flows are higher wasting more of the energy as heat.

Doesn't this ignore the fact that if you brake later, you might have achieved a slightly higher top speed, therefore there is more energy to recover?

[SiLo]

Same amount if energy, its just expelled over a shorter period of time.

[bonjon1979]

Same amount if energy, its just expelled over a shorter period of time.

How is it the same amount of energy if one car is going faster than the other?

There is more energy in the event of a car traveling at 205kph braking down to 150 kph, than a car traveling at 200kph down to 150kph.

[Pierce89]

Bonjon is obviously correct on this one.

[SiLo]

I assumed the cars were moving at the same speed prior to braking. Otherwise its a stupid thing to argue.

It's like saying the braking energy released braking from 200mph to 0 is greater than one going 20mph to 0. You have to have only one variable there to actually determine what is different.

So assuming the same speed at the point of brake application, the energy should be the same. There are a few different scenarios here though:

1. The person that brakes LATER could still be braking for the same amount of time as the person that brakes earlier.
2. The person that brakes earlier does so for a longer amount of time with less braking pressure.

In situation 1, the person braking later has a later turn in point or is turning slightly at the end of the braking phase. In situation 2, the person braking earlier can have the same turn in point and same point of release for braking, it's just that they take longer to do it (which isn't as fast).

My two cents. Hope that clears some things up for people.

Jackie Stewart said something along the lines of "it's not when you brake but when you come off them that matters". Being the latest braker isn't necessarily the fastest way around a track - especially if doing so unsettles the car. If you brake slightly earlier, come off the brakes slightly earlier and then go in with the car perfectly working all four tyres and then are able to get on the power a bit earlier than the late-braker you'll probably be quicker. Or more simply: corner exit speed is more important than corner entry speed.

I'm not so sure it's that simple when you consider KERS harvesting.

[PlatinumZealot]

Late breaking done right gives a higher cornering speed and thus you spend less time on the throttle through the exit. Equals less overall fuel usage.

After Malaysia Toto said the engineers will work hard to find out why lewis finished the race with 4 percent more fuel than nico. Up to this day we havent heard the result of that investigation, but we do know that that fuel usage gap still exists.

I assume they know what it is. However, I'm betting that whatever Lewis is doing that saves fuel, is something Nico has a hard time adapting to, or feels uncomfortable doing.

[alexx_88]

In my mind, a late braker will have a lower cornering speed, but he will happily trade that for more time spent on the straight at top speed. That means that his braking period will generate more energy compared to the normal braker, but will also use up more by being at top speed for longer. The energy gain could only be made by the fact that he'll actually slow the car down to a lower speed compared to the normal braker.

I think Hamilton might be the better and later on braking than Rosberg. If you bring in the 'lift and coast' topic, then Hamilton might be more efficient on that one. He has better fuel consumption than Rosberg, maybe because he lifts and coasts better and longer than Rosberg. If Hamilton lifts and coasts longer, then he will also brake later.

In Monaco radio messages were about gear changing: longer/higher gears by Hamilton. Whatever it is can be difficult and only shows how weird fuel saving importance is in F1. The goal is to be as fast as possible and in case of Rosberg (let's say) if it's this particular gear-changing pattern that makes him drive at optimum he should not be disadvantaged to such extent and adjust mid-race.

Who cares if they are friends, why do they expect fake hugs after losing races, will Merc sell less cars because of that?

LEWIS HAMILTON AND NICO ROSBERG ANNOUNCED AS NEW AMBASSADORS OF IWC SCHAFFHAUSEN

Outwards appearances are extremely important. Happy smiley people with their wonderful watches....

is that not an old picture?

I think Hamilton being the latest of the late brakers is an urban legend. In my view he doesn't brake later than anyone else can brake... he just seems to be able to be more comfortable doing it and he does it more often. And, Just by observation, Nico can get just as aggressive on the brakes but he tends to be too aggressive when the car's weight changes - a bit inconsistent and locking up both front wheels as we see in a few races so far. I think I am beginning to buy into the notion that Canada will be the track to separate the true late brakers from the pedal pushers... should be fun watching the pretenders lock up left right and center...

For the coasting bit... for the life of me I don't know why FIA don't show the RPM/throttle and brake display more often during the races.. It's like you need a Sky account to get any meaningful watching these days. let's not even mention the God awful camera angles which stick to cars like all I'm seeing is a chassis and some tyres for the whole race...
