I take it you are not a fluid dynamics engineer. Lose 1/3 of the aerodynamics and the other 2/3 then become a) Just drag or b) at worst, a serious cause of imbalance.

In years gone by all this stuff would have happened and no one would know a thing about it. Now in 2016 we get to over-analyse every small thing. Ripping a rear bumper off in testing seems pretty normal. Nothing to see here.
Having discovered last Thursday the Yaris WRC on the Corsican asphalt, Jari-Matti Latvala was in Italy this weekend at the wheel of his Audi Quattro for the Prealpi Master Show (December 10-11).
No rest for the Finn who found on Monday morning the Yaris steering wheel for a new day of testing, still on asphalt, organized this time in France.
The former Volkswagen driver then flew to Finland and more precisely Helsinki, or this Tuesday, the Toyota Gazoo Racing Team officially introduced its team as well as the Yaris WRC 2017.
On Wednesday, Jari-Matti Latvala was back in France for four more days of testing. After a day on the asphalt, which ended in hospital after pain in the back, the Finnishman took control of his new mount this time on earth this Thursday. (=> Videos of the day on earth)
The Toyota driver will finish his "big week" by two more days before being replaced by his teammate Juho Hanninen.

Meeke test https://youtu.be/1DXjuhGcAYg
Is it me, or are the centre vains on that diffuser flexible, made of rubber stop them getting ripped off. You can see them flexing at 3.42

Yaris today

Another great video with Meeke
I think that Citroen have made a really really good car.
Watch at Meeke's driving style. He is using many times the brakes on the exits.

Missing rear bumper doesnt need to be because of an accident.
Citroën has a very good testing methodology, and they also do things as test with missing/damarged aero, to test the handling consequences. (Not only in WRC, but also in the WTCC, where they tested with damaged cars.)
This car will be a rocket!
Perhaps a setting to control the central diff?
Test Stephane Lefebvre Monte Carlo 2017 (C3 wrc drone) acceleration seems brutal from here

Another yaris movie today. It seems to be improving day by day ...

they are improving,but the others are a lot ahead.
Watch how easy it oversteers at dry tarmac,or the blue smoke from tyres at hairpins due to excessive spin.

also haven't see yet a standing start with lunch control

Seb testing the Fiesta WRC2017 in Sweden this week.

yes suspension.central diff mapping,and diff preloads.
A pic on WRC Rally Fans FB page shows damage to the rear of Meeke's Citroen. Also there is a pic from Latvala's test showing that he has already christened the Toyota! (though rear damage is not as bad as Meeke's)
This ? Its been posted here already.

totally night and day. m-sport were testing in the same place a month ago, Camilli https://www.youtube.com/watch?v=Een58mfH6Z4&t=1s
Not defending Toyota or anyone else.
Just when you have few runs on video it's hard to judge about general performance of the car.
Usually things like slight oversteering are very easy solvable with tiny setup changes (or little more deeply with LSD changes, damper shimming, etc). So those things might be misleading. If we don't know the general plan of tests, on what they work, what is the idea of particular tests it's hard to make 100% statements. It might be early state of working on setup for such road, might be checking some settings to see how car reacts, might be some work on diffs or alignment, or working on cambers to suit the tires, etc.
Especialy tires management might be an important factor this season with those new cars creating more downforce - higher corner speeds, etc. Loix was recently testing new tires using old 2l WRC Citroen, so no doubt that's still work in progress.
