Exactly. It makes no sense whatsoever to combine weak engine with the longest gears hence why I do believe the real issue was not the engine because I don't think they are stupid in M-Sport. It seems like they just didn't get everything together as good as other teams and that long gearing is probably one of the miscalcullations.

It's not a weak engine, it's the same engine as before. It's just weaker than the other because they have improved.
And i wouldn't be suprised if m-sport uses old gearboxes, just like they use old engines. They have nothing to win this year, they are just participating.

Maybe they are lacking in torque on long corners because of the combination of the engine and the long gear ratio? As we know, the engine peak powers rarely increase, but they can increase torque where it's needed for the drivers.

M-Sport's engine isnt the most powerful, hence the coming upgrade.
Isnt a long gear ratio good for when there are long maximum speed sections like the Arctic ?

The event was won by the car with the shortest gear ratios of all.
Look at Rally2. There is most likely negligible difference between Polo and Fabia engines. Polo was faster. Why? I don't know but clearly not because of the engine. Which one had longer gearbox? Fabia. Is it a coincidence? Maybe. For sure such long gearing as M-Sport used, was a mistake.Stupid is as stupid does. Forrest Gump

Sure lack of torque and too long gearing is wrong combination but it's so obviously wrong that one must ask why would someone select that?
I have only few ideas why that would be possible and still be somewhat logical. Either they tested on a wrong track which didn't have a character of Arctic stages and didn't get the right feedback or they changed something last minute which had trown a pitchfork into their previous effort and ruined all what they did before - could be for example last minute change in aero setup. Or they used wrong setup just to use parts they already had available to save money.
I don't know, IMHO it must have been a combination of more things. Everybody likes to speak about engine or gearing but aero, differentials, suspension, everything playes an important role. As I said before - I don't believe that people working in M-Sport are stupid, hence why I hesitate to accept that easiest but rather stupid explanation.
That's for sure right. I just wanted to use that example that long gearing didn't always make the car faster on fast events and in this case both cars had basically same performing engine
Otherwise I mentioned before that I guess that Printsport know-how has played probably larger role than general difference betwen Polo and FabiaStupid is as stupid does. Forrest Gump

Suninen estimated that at the moment they have 5-10 hp less power than the competition. Once they have the new engine he believes that all the cars are within 1-2 hp of each other. He did not comment about the shape of the power curves.
From what I gathered he felt the high speed performance issues were more about suspension development and coming up with setup that would work both with and without the aero loads. At present he said that they are struggling when speeds start to rise above 120 km/h. He seemed quite frustrated by lack of testing and availability new parts to test when they do have tests. He said he had once even brought his own Reiger dampers to a test because he wanted to try something new, but in the end they did not choose those.
Do any of you know how many gear ratios are homologated for WRC cars? Or can they be chosen freely?

These cars were going nowhere,fast. Getting rid of them was crucial for the survival of the championship. Group Bs were amazing cars, too. But, having fatal or life threatening accidents at every...
