WRC Testing

c3 seems to have longer suspension travel from ds3.Dont remember to have see so much travel at any ds3 photos.

The wider track of 2017 cars shall help to achieve bigger suspension travel for all teams since the main limiting factor (as per words of VW designers) is the reliably useful angular range of the driveshaft joints.

Ever since the cars have gone to long travel suspension I have wondered repeatedly just how much travel they actually have. (since I pay the rent making among other things suspension).
Early 1990s it was around 200mm travel.. Mid 90s I have some Group A Lancia front inserts and they were 225mm...

Most of what I make is 200-210mm...

Clearly the really long arms and the gentler arc they make allows the CVs to be less stressed but I really still cannot find any real published number for the travel...

Does anybody really know?

And Latvala breaking things... Well some people just break things..
I had a friend who did the same events I did in '77 and 79 doing International moto-cross mostly in France but also Suisse and Belgie and he was just a bit faster and just a bit heavier but same bikes and same wheels...and same suspension--about 310mm back, 300mm front..and he broke or collapsed wheels frequently, while I would do a check occasionally but could do 2 seasons without any worries or thoughts.. KTM and Husqvarna had good wheels,..
But he's break them..

maybe br21 can help us with recent r5 travel at gravel and asphalt.

Focus WRC -06 had 280mm travel rear and 300mm front(with rough rally option +20mm)travel. This is damper travel not wheel travel.Current WRC Fiesta is very close though I don`t know exact figures, R5 Fiesta has slightly less travel than WRC.
New C3 has dampers situated like VW, Skoda and Ford next to driveshafts not on top which allows more travel. As has TMR Toyota(TMG Toyota had as Hyundai and DS3)

Now it finally looks and sounds like WRC should.

no lunch control and antilag though yet.

Do we know exact regulations? Not saying it's the case but it would be interesting to know if they can use electric turbo to completely avoid ALS.

Do we know exact regulations? Not saying it's the case but it would be interesting to know if they can use electric turbo to completely avoid ALS.

2017 regulations say the following:

The turbocharger must be single turbocharger, with single stage compression and expansion, and must not have variable pitch or variable geometry.

I guess the electric turbo count as a second turbo, so not allowed.
