2014 Canadian Grand Prix - Montreal

Here's how JB ended up 4th

Thank you. Alonso was breaking at the " Much too late " point here !

Apparently MGP failed to take precautions after seeing that the temps in the Control Unit were getting too high ... seriously ... wtf -.-

from AMuS Race Analysis: "Mercedes-Teamchef Toto Wolff musste nach dem Rennen zerknirscht zugeben, dass der Ausfall der MGU-K wohl zu verhindern war. Man habe die hohen Temperaturen in der Hybrid-Steuerbox zwar erkannt, aber nicht rechtzeitig Gegenmaßnahmen eingeleitet."

Mercedes Team Principal Toto Wolff had to admit compunctiously that the MGU-K failure could have been avoided. The high temperatures in the Control Unit were recognized but countermeasures were applied too late.

The what and the what... what what what?
Really guys stop arguing about Perez/Massa and lets talk about this "technical" issue in this forum.

Vettel's take on the renault PU in the post-race press conference:

Q: So how did you make it past Perez in the end?

“Sergio braked early. They ran into brake problems and it got progressively worse. That’s the only reason I even got a chance to overtake. It was obvious we could have gone faster and Felipe caught our bunch quite rapidly, too. The pace of the Force India was quite slow, but they were clever and defended well. We just didn’t have the oomph to get past.”

“In the end it luckily worked out for me. I came out of the last corner well and he missed his breaking point. That brought us side-by-side. I went out of the slip-stream – DRS open, engine on full pelt and could see him still pull away. Well that’s just frustrating. His DRS is closed, mine is open and that should make about a 15 kph difference and even then we go nowhere. That was that for my race, because we couldn’t came up with something clever in terms of strategy.”

This says it all really.

Indeed, add to the equation that Hulkenberg has older tyres so he couldn't brake as late as he would want to, that was really close!

Is there such a thing as fuel consumption chart per car per race available anywhere?

I also didn't notice the graph (on sky sports) they usually show from time to time during the race

I remember it was shown before the 2nd half of the race ( I think around lap 33) and I only remember Rosberg had used ~46 kilos of fuel while Hamilton had used ~44.

I don't think I helped you that much

I'm still curious about how they got that merc to the finish line at similar pace to competitors without running out of fuel while having basically no kinetic energy recovery from braking, they might have still be able to harvest some out of the exhaust via turbocharger (which would imply even higher overall fuel consumption) generator to have at least some juice in the battery to run the internal combustion engine properly - mainly from driveability aspect - maintaining the speed of the turbo ALS wise (which supposedly is done via same electric motor-generator on the turbo) etc, but all in all - ROS should have had real fuel saving problems at the second part of the race

anyway that whole situation (if indeed ROS had zero MGU-K functionality past aprox mid race distance) raised so many questions and that fuel consumption data might shed some light as to how much energy is actually harvested and used up by MGU-K vs H, it's a shame that none if that was addressed in the post race analysis as far as I remember

one more thing - there was a radio message where Rosberg was asking something about brakes, and I think that most people missed the part where the answer was something in lines of - "..... teammate has the same problems", and, as far as I remember, hosts jumped to conclusion that it was HAM they referred to teammate, when actually it was "Fellipes teammate has the same...", which meant that Rosbergs problems, while similar to Hamiltons (who had another problem on top of that), might have been even more related to why Bottas dropped down at the last part of the race

What actually happend to both Lotus cars?
And what caused Raikkonen's spin? That one looked to have a mechanical reason.

I think I saw in one replay (Marussia incident perhaps) that one Lotus (supposedly Maldo) jumping over kerbs, and later had some sort of bodywork damage (the fin near the side pod entry was loose), and GRO had rear wind side plate damage near the end of the race - they would/should have been black flagged if they would continue racing with those parts loose on the cars

Raikkonens spin looked really weird, like rear end instantly lost traction, which in my opinion, can happen only due to glitch/error of the MGU-K systems power delivery, IC simply wouldn't have been able to instantly brake traction without any warning whatsoever to the driver

Perez had no rear brakes left.

Perez had no rear brakes left.

And why does that excuse him swerving off the racing line?

[tonmeister]

One thing to consider, pointed during live broadcast by Pedro de la Rosa, is that both Merc´s failure came after pits. The pit area in Canada comes after the hardest brake zone in the circuit. If you come into the pits after a harder than recommended braking, there is a good chance that you will toast your brakes for good while stopped...food for thought.

This video clearly shows what happened. Five place grid penalty is lenient:

If anything, he should've refrained from fighting if the problem was this dramatic.
