Rally2 (ex-R5) News

Is this why it nods it head and bucks around like a mad dog on a lead too?

, dunno what exactly this means but sounds funny. I have no idea for the car behaviour, I'm only commenting the sound.

All current R5 cars have ALS, but their strategies are little bit different.

Only one corner, and poor picture quality but quite interesting seeing the different performance out of this corner of the various cars. Fabia seems to have significantly more "spunk" out of that corner than the other R5s:

R5 has 32mm restrictor.
Biggest problem in R5 cars is that FIA control pop-off valve which is purely mechanical and car manufacturers can't control them as they would like to. So they are forced to make a lot of strategies to limit boost just below pop-off activating level, so sometimes throttle is closing automatically a little bit, sometimes wastegate opens, etc.

The restrictor size of N4&R4 is of course 33 mm and not 32 mm as my old head suggested.

Is the waste gate controlled by a spring? If it is, the waste gate starts to leak before the boost reach 2,5 bar absolute.

At which revs is the torque 400 Nm and power 300 hp? Peugeot & Citroen says the torque is 400 Nm @ 2500 rpm and power 280 hp @ 6000 rpm. At least the revs must be above about 5270 rpm (for 300 hp) otherwise the torque would have to be higher than 400 Nm to achieve 300 hp.

280 Hp is most likely bullshit value

Also the torque peak is probably in reasonably higher rews. The turbo-pressure is too low for such characteristic with so small engine in my opinion.

Ooo, undisguised 'real' photos of the new Fabia road car:

280 Hp is most likely bullshit value

Your estimation?

[Mirek]

BR21 already said Fiesta R5 has 300 Hp. No way Peugeot would have 20 Hp less.

[Sulland]

The sound of 208 T16 or DS3 R5 is OK for me. It's VERY loud, louder than S2000 cars and although it has no anti-lag sound it's still great to listen. For example today on Pindula I heard Magalhaes like 30 seconds before he came while with Kopecký it was some 20 seconds for quiet bubbling and only around 5 seconds for the engine itself. On the city stage in the crowd I didn't hear the Fabia R5 at all!

What is the db level allowed by FIA, or isnt it any limit?
Skoda need to put a louder exhaust system on the new R5, and problem solved.
Sound is a large factor for the fans, it should sound like a competition car!!

“For all cars used in Rallies and unless the limits imposed by the local authorities are lower, the noise level on the open road must not exceed 103 dB(A) for an engine rotation speed of 3500 rpm for petrol engines and 2500 rpm for diesel engines.”

What the dB(A) is you can read more about here:
