Rally2 (ex-R5) News

"Could be seen in WRC2 next year" ? :-D I thought it has homologation only for Swedish championship. Anyway I am curious.

They applied for FIA homologation.

I'm afraid it's going to be another MG S2000 story but with the PSA misery why not to try. Fingers crossed for every competitor.

Jan Cerny tested 208 R5 today

Don’t they even check what they publish?

Power / Torque: 280hp@7500rpm / 450Nm@7500rpm


With 450Nm@7500rpm the power would be 481 hp (with a 32 mm restrictor) .

What rpm You think this tourque is possible?

[Mirek]

If we suppose the figures are correct (but I doubt them since Fiesta has more power and less torque while it still has pretty flat power curve)

Purely mathematically...

T = 450Nm; P = 280Hp = 206kW = 206000W

T = P / omega
omega = P / T = 206000 / 450 = 458 rad/s (angular speed)

omega = 2 * pí * RPM / 60
RPM = (omega * 60) / (2 * pí) = (458 * 60) / (2 * 3,14) = 4376

Be aware that having 450 Nm at 4376 RPM and 280 Hp at 7500 RPM means having 280 Hp all the way from 4376 to 7500 RPM which is theoretically possible but most likely the maximum torque is in this case in lower RPM.

Anyway it's just theory

[br21]

In theory it's possible to have 450Nm torque, as it's turbo engine, so relatively easy to map it stronger. Same thing was with Fiesta for example, but then engines started to be not reliable. But for sure those exact figures are bullshit as with so small restrictor car chokes above 6,5k RPMs and looses in performance, so no way it has those figures at max rpms. I think those values are just PR talk. And it won't be easy to homologate that car, as FIA is really strict with R5 homologations and way bigger companies (than that Ralliart Sweden) were struggling to do it quickly. Plus I'm not sure what Mitsubishi will do. As car is relatively brand new, not tested enough (comparing to other R5) and when they see now Peugeot problems they might be afraid if their Mitsubishi will have similar issues - it's not good promotion for company for sure. And when you start with some shit, then because of limited Jockers, etc you're in deep shit almost forever.

Anyway I hope more and more manufacturers will build R5 cars, so competition will be stronger.

is it me or does the r5 cars sound dreadful/quiet/boring ? they don't exactly get the hairs on your back standing

Fiesta and Fabia sound boring and silent, yes. 208 and DS3 sound great and very loud.

[RS]

208 and DS3 sound great and very loud.

A lot of the time the DS3 and 208 are even quieter than the Fabia and Fiesta.

[Fast Eddie WRC]

I have to agree the DS3 & 208 sound far louder than the R5 Fiesta (in fact more like WRC cars, especially the DS3).

Regarding torque - these modern 1.6 turbo cars can definitely make 450Nm with the mapping, but it will be at around 3000-4,500 rpm.

(PS. My Focus ST is only re-mapped and makes this much torque too... but it is a 2.5T ! )
