Yep wwbroe, you're right it was day 2.
The Sadev rear diff has a hydraulic clutch that should release when the handbrake is used for turns. I know there were some issues with the pressure it needed to release being quite high. That meant that it didnt always fully release on pressure from the handbrake hydraulic system.
Tazz: Thanks.
So, here it is. Peugeot 207 S2000 doesn't have central differential. Confirmed.
Thank you Tazz for the information.Quote:

Isn't Abarth also using Sadev? So the Abarth and all others using the Sadev should have the same clutch?
There is a lot of torque going true the clutch so I think the problem with relesing the clutch is that it need a high hydraulic pressure to relese the clutch.
I suppose not having the centre diff also saves them some weight and saps less power.Quote:

They would need to have at least beter engine and reliability...
Yesterday I saw the MotorsTV coverage of rally Russia. The Pugs had a lot more punctures in Russia apparently due to wheels that were strong enough for the Russian conditions.
There was an interview of Anton Alén in the Finnish motor sport magazine “Vauhdin Maailma” (07/2008) where Anton told that he yearn for more torque and broader rev band. Further he says that the revs shouldn’t drop below 7000 rpm because below 7000 rpm the engine is very lazy.Quote:

Whatever the correct figures are for the Punto, Pug has a broader rev band and the peak torque on lower revs compared to the Punto, or has higher torque at 6500 rpm.
Don't get that numbers too serious. Those on database are partly my work... :D
225 Nm can't be engine torque. It must be on wheels since such engine would have less than 270 Hp. In fact private Puntos had about 260-270 Hp in last season.
But the torque difference between 207 and Punto is obvious. The more because Pugs are usualy going on medium gearbox on stages like we have. Fiats on short.
