Ferrari F14T

So, it was 18kg a few days ago, now it's 13kg. At this rate their engine will be underweight by the time they get to Malaysia.

ROFL

Gray Matter says ..

The Italian team was fairly invisible throughout the weekend and Raikkonen was well off the pace of his team-mate Fernando Alonso as he complained that the car did not suit his driving style.
The team knows the problem - most likely poor handling under braking and corner entry due to the functionality of the energy recovery systems – but they have admitted it’s not a quick fix.
It will require different parts to be designed and manufactured – but at a time when he needs to bed into the team and get to grips with Alonso, it’s just what Raikkonen didn’t need.

He doesn't mention anything about weight.

I think there's 3 seconds per lap from getting these systems optimized and calibrated properly. Think about how much trial and error has to go towards making the mgu-h synchronize perfectly with the mgu-k and the hydraulic brakes, and transfer these three negative torque forces into precisely the amount of braking pressure required by the driver. Calibrating the pedal weight to the perfect amount of corresponding torque along with the electronic differential, and most important of all generating proper braking feedback is not an easy task. On the one hand you have the completely unassisted front hydraulic brakes which can lock up, whereas the rear braking system has a completely different feel, and difficulty in tuning the whole system for proper dynamics during trail braking is daunting to say the least.

I dunno about three seconds but I'm happy to be wrong.

I just went back and watched the race and I have to say what I observed was basically a bad brake imbalance on KR which is devastating when trying to pass or fending off being passed. A lack of power on both cars. Kimi's start was great, but Massa just passed him back up under acceleration to the first corner. It's an outstanding example of the power differential they are suffering with. Another example...even when down a cylinder, Hamilton was able to hold off Fred's Ferrari all if lap 3.

That said, the car seemed strong cornering. Fred would often finish corners well inside the car directly ahead. He was able to stay glued to the incredible Hulk lap after lap without tire destruction or aero issue seeming to hinder his ability to stay close. Had Ferrari a synced PU, he'd have been passing guys like Hulk much quicker imo.

I really think with their improving the regeneration power system sync to the rear brakes & engine, they really will be very competitive. I just want em competitive. No team being dominant makes for better racing in general and I'd like to see Fred on similar form to 2006, 2007 in a competitive car.

brake by w. is not developed by the same company who use other teams? Brembo! why installation is so problematic????

[alexx_88]

Brembo probably supplies just the mechanical parts. The main difficulty this year is that, while the front braking is still done like on a normal car - driver presses pedal -> braking fluid pressure increases -> pads are pressed against the discs, the rear brakes are much different.

The brake pedal load cell is read by one of the ECUs on the car (possibly the Standard one) and determines how much brake force the driver wants to apply. Then, in theory, by using maps and some algorithms, the ECU splits this braking force across 2 components: the MGU-K generator and the actual rear brake cylinder. When and by how much these two contribute determines the mapping of the brake by wire system. Now, they probably were able to simulate and map the system pretty accurately before actually getting the car on the track, but, as you know, driver feeling is more important than rough numbers, so they probably just need to spend some more time adjusting the system to each driver's liking.

What I don't get though, is how much different is this system compared to the years before when a similar mapping was employed because of the KERS.

The difference is because KERS was twice less powerful, so the driver could sufficiently adjust braking action using his own brake biasing.

Yeah, this year the entire system is controlled electronically and you'd probably have predefined braking maps which can be selected on the steering wheel. The problem is optimising these maps.

The mgu-h doesn't slow the vehicle but it does have an effect on engine braking.

Doesn't sound like something is broken as much as an adjustment limitation.

Tobias Grüner of AMUS is reporting that the Ferrari PU turbo layout is similar to that of Mercedes. Turbine at the rear, MGU-H in the middle of the V, compressor at the front. Wonder how long it will be before we see actual photos of the three power units.

[Owen.C93]

Looking at the Marrusia, I doubt it.

here is the photo that I had already 'posted, I tried to improve it with phoshop but it is always poor definition
