What updates have the factories done on their cars for the 2018 season?
changed the liveries...
oh wait...
Toyota is even more uglier than before.
Really? I thought that without taking liveries into account that it was the second best looking of the four cars, second to the i20.Quote:

Can they really do anything extra outside the normal homologation jokers? So 2018 cars are just 2017 carsQuote:

Most normal looking is Citroen, their shapes are good looking, Hyundai and Ford are like Japanese roof styles with those wings.. Toyota is bizarre with those big drawers for cd-s.. Yes they are exciting all of them, but they could produce beatiful and still efficient cars, not just some random styles like in NFS: Underground 2Quote:

Hyundai starting with the updates Neuville had at the end of 2017
Well, i think that at the moment the sophisticated looks are more "rally/racecar" than the previous generation which was more similar to some NFS-style boyracers tuning.
Form follows function.
There is still quite a bit that can be done for the "optional" homologated and non-homologated parts.Quote:

Nice summary, two things:Quote:

- In Sweden it seemed that the ribs in C3 diffuser are now much stiffer since the "flapping" seen during whole 2017 wasn't there so much
Thanks a lot for your great contribution, already incorporated into the post.

Our new post tries to explain how WRC cars use energy from the exhaust to gain downforce - Exhaust blown diffusers in WRC
Hope you like it!

Have the rally cars reached the same issue as in F1, where the aerodynamics are getting to advanced, and cornering speed too high?
In F1 it makes overtaking hard, and in rally it moves us towards safety issues for the drivers.
F1 will make changes, will rally?
no.
the end.
Don't think so, cars are pretty fast and safe. New car homologations will be allowed in 2020, but regulations are expected to be stable for some more years.
F1 is another (sometimes crazy) world
Since the first videos of ‘17 WRC cars testing we got to know they were incredibly fast and last season has proved they were the right choice for the series; their ‘wow factor’ is helping WRC to recover the interest of old fans and attract new ones.Quote:

Anyway, it seems premature to be asking for major tech changes as we’re just on the second year of an initial 3 years cycle; it’d be great for the series to keep current regs till 2022, the end of the second cycle. Regs stability is vital to attract more manus and these cars simply rocks!
This is nearly same accident from 2009 with a gr.N car with roughly 120 Hp less than the WRC (equipped with Prodrive T45 rollcage). Was it less dangerous? I don't think so.

Who are the firms delivering dampers and springs to which WRCars and R5s these days?
AFAIKQuote:

You heard it here first.
See how wheels impact on the aerodynamics of WRC cars and the solutions teams implement to minimize such impact, in our new post

2:19 in the video you can see the covers.
I have a question for the rally guru's on here. In service park, i sometimes saw a wrc car going full gas high in revs (stationary and while on standards). All team members put there fingers in there ears. This is than repeated for three or four times.
What is it that they are testing or controling then?
transmission changes that they have to be sure that gears change properly,to test variable parts that changed they work properly,they dont leak oils/waters/fluids,changes at ecu maps that they have to secure that work proper etc.
Its call a boost check, it is done to make sure the ALS and boost level are correct.Quote:
