WRC goes Super 2000!

But it has to be a very low efficiency turbo if they only plan to take out 50 horsepowers from it ?

They are probably aiming more for torque then. How much more torque will it produce ?

You dont need 4wd or turbos to be competitive. I think it would be better if they made the rules so you didn't have to have 4wd or turbos to be competitive. That would be cheaper too. Have a look at the links.

looks nice. but when you look at the cars, you see how old they are. 2wd and especially rear wheel drive is just not commercial anymore, only few manufacturers make them anymore for everyday cars. and what it comes to front wheel drive, its just mostly horrible to watch. its ok for juniors who can practice handling with cheap cars.

but here's one link for u since you like those:

there's also more videos of Toni driving his hobby M3, they are all pretty furious to watch!

There is a 30k€ price tag for the kit and the whole purpose of it is that it's removable within short time so that you can use the car in different events as well not just in WRC.

As was said, that is nonsence. You can't get working turbo car from S2000 by fitting turbo in 30 tousand Eur.

With turbo You have to use new cylinder head, new pistons, new crankshat, new piston rods, new valves, new camshaft, new cylinder sleeves, new exhaust, new electronics, new air intake, new clutch, new gearbox, new propshaft, new driveshafts, new differencials etc.

That would always cost more than 30 tousand and would never be easy and fast to mount.

No way! National championships have always been at their strongest when running the same equipment as the WRC (and I include the Formula 2 British series of the late '90s in that, as F2 cars were also WRC equipment.)

Morrie Chandler said that they couldn't stop any ASN from letting the new WRCs run in that ASNs duristriction..

Correct

Apologies I meant that the new spec World Rally Car should be allowed in national championships and Regional so if you don't have a WRC event in your country but do have a regional round the national championship entrants will be able to battle with visiting compeditors who also can have the new spec WRCs as well

So those countries could have a WRC type event without it being a World Championship event

]Mike, that joke was in fight for PWRC victory...

On day 1 it wasn't. When it gets a little muddy, then the S2000 car is just to unspectacluar (IMO). Sandell critisied the car himself because he couldn't put the power down...

True. Nice video. Nice car too. Although alot of the cars over here are 2wd but anyway it will probably never be that way again. And like you said its ok for juniors to practice with. Anyway it looks like the WRC is heading in the right direction and once the get the kinks worked out it should be good.

But 2wd can also mean the very exciting-looking F2 cars of the 1990s, which demanded a lot of skill to drive quickly. I think that sort of car should still have a place at the top of the WRC alongside four-wheel-drive equipment, which, let's face it, is far less representative of the average road car.

The FIA WMSC decisions about the new WRC regulations:

"From 2012, it was agreed in principle that world rally cars will be four-wheel drive and turbo-charged, based on mass-produced Group N and S2000 specification cars” (27/06/2007)

"The new technical regulations for the future World Rally Car will become effective from 2011. The WRC Car will be based on the current Super 2000 and Group N cars, fitted with a supplementary kit, which includes turbo and rear-wing additions. The kit must be able to be fitted or removed within a defined time limit, to be determined.” (26/03/2008)

"The WRC Commission will therefore review the current direction of the proposed 2010 technical regulations, in order to ensure that the original decision to use no more than a removable, bolt-on kit to change a Super 2000 or Group N car into a World Rally car is maintained.” (05/11/2008)

"As already announced, the 2010 World Rally Car will be S2000 based. However, the removable kit, already adopted by the WMSC, will be redefined with no electronic benefits, or similar upgrades, to ensure cost reductions. The new S2000-based World Rally Car will only be permitted for use on World Rally Championship events.” (12/12/2008)

They took one and a half year to decide that the new WRC will be based just on S2000 cars and have electronic restrictions…how much time they’ll get to determinate the kit technical regulations (putting in other words, when will they realised that the removable kit format it’s impractical?!?).

[quote="OldF"]
What does FIA actually mean by “the 2010 World Rally Car will be S2000 based”. Does it mean that the manufacturer has to first homologate a S2000 car and thereafter the WRC kit?
quote]

Regarding the previous kit-cars regulations (KC1600 and 2000), you’ll have to get a homologated S2000 base car and then produce and homologate the kit variant. That could be good news to the S2000 market, spreading the range of competitive cars for privateers and regional teams.

[BDunnell]

Here is a rather dull question, but I'll ask it anyway. In which Group will the new cars be categorised — A7.5 or something? Or will the FIA introduce a new Group system?

Mirek, you forgot the cylinder head bolts and maybe the joints in the wheel hubs.

The parts list for the turbo kit is quite long and replacing all these parts take some time.

There is a 30k€ price tag for the kit and the whole purpose of it is that it's removable within short time so that you can use the car in different events as well not just in WRC.

A S2000’s torque is about 250 Nm and if the boost of the next generation WRC cars were limited to 2 bar (as mentioned in Gpweek, issue 21, page 35), the torque would be about 600 Nm. That is 2,4 times the torque of a S2000. This means for a NA engine and a turbo engine, that have similar cylinder diameter and stroke length, the force pushing down the piston at combustion stroke is 2,4 times bigger for the turbo engine. So all the parts beginning from the engine to the wheel hubs have to cope with this increased torque.

Here is a link where it’s explained why the compression ratio for a turbo engine has be lower than for a NA engine.

http://www.turbobygarrett.com/turbob...o_tech102.html

“Factors that influence the compression ratio include: fuel anti-knock properties (octane rating), boost pressure, intake air temperature, combustion chamber design, ignition timing, valve events, and exhaust backpressure. Many modern normally-aspirated engines have well-designed combustion chambers that, with appropriate tuning, will allow modest boost levels with no change to compression ratio. For higher power targets with more boost, compression ratio should be adjusted to compensate.”
