IMO the lower exhaust has little effect on tyre temperature or diffuser effectiveness.
1. It simply allows the coke bottle shape to be perfected reducing drag and smooths airflow over the rear aero array.
The negative may be excess heat on the push rod suspension.
I do not think Ferrari will be able to add a pull rod system within the regulations and time frame.
2. I also believe that the FIA has allowed these shakedown runs in an attempt to get teams like Ferrari back up to speed for closer racing.
I would be worried that such a radical change at the rear might upset the aero balance without more work on the diffuser
Although in-season testing is banned, teams are allowed to conduct limited 'promotional running' - which has been used by several outfits this year to try and get mileage on new parts.
Ferrari , over the winter, had found a 10% saving in fuel consumption. This had nothing to do with exhaust manipulation, as there was no back pressure. (it is back pressure that stifles the engine). The answer was in new engine mapping and also in their valve control system, the one that gave problems at the start of the season. This has been rectified, and Ferrari engine is as economical as the Renault engine, and better than the Merc. Changing the exhaust system will make no difference, and in fact may improve the consumption further.CZOLG wrote:I am quite curious about one thing.
Much has been talked at the beginning of the season about Ferrari's effort to lower the fuel consumption and the exhaust was supposed to play a big part in it. Now it's been radically changed. Did they find out consumption is not as big a problem as expected or did they manage to optimise it for the new location too?

I doubt the Ferrari powerplants are as economical as the renaults engine, look at the ferrari powered cars, those are real battleships with their lengths, i dont know why that is needed if they are as economical as the incredibly short renaultgilgen wrote:Ferrari , over the winter, had found a 10% saving in fuel consumption.

They have oil tank in front of engine, behind fuel tank. Can be zillion things actually. Aero, weight balance etc...wesley123 wrote:I doubt the Ferrari powerplants are as economical as the renaults engine, look at the ferrari powered cars, those are real battleships with their lengths, i dont know why that is needed if they are as economical as the incredibly short renault
The length of the car has nothing to do with the fuel consumption! It is to do with the packaging and handling. Merc had to lengthen their wheelbase, but do you honestly think that this affected their fuel consumption??wesley123 wrote:I doubt the Ferrari powerplants are as economical as the renaults engine, look at the ferrari powered cars, those are real battleships with their lengths, i dont know why that is needed if they are as economical as the incredibly short renaultgilgen wrote:Ferrari , over the winter, had found a 10% saving in fuel consumption.
