The route is out, quite much new again compared to last year, only two stages have remained. Friday driven in the South end of the island, Saturday at North-West near Bastia and Sunday at Nort-East near Calvi (for the first time since 2013). And stage count is now up to 14!
entrylist http://www.tourdecorse.com/site/wp-c...Corse-2019.pdf
only 2 guys in WRC2PRO, Rovanpera and Pieniazek but otherwise amazing WRC2 list with Camilli, Kajetanowic, Veiby, Katsuta, Loubet
and of course JWRC too.
Bonato, maybe Gryazin and especially Ciamin I would find more interesting for Corsica than Veiby or Katsuta.Quote:

This WRC2Pro turned out to be a real joke...
Andolfi was strong last year there.
Now back to Hyundai, I don't know if he will be able to be as fast.
Kajetanowicz is testing his new car with BRR in Austria. Tour de Corse will be his debut.

FIA Rule says that WRC2 numbers start from 41-Quote:

Yes it is weird that these things seem to happen every year, and it is either Monte or Corsica (or both).Quote:

Also are the permanent WRC numbers always "frozen", even if the crew is not taking part in a certain rally? I noticed that for Corsica Bertelli's permanent number 37 is used by Solans in WRC2, but Mikkelsen's number 89 is not used, it is skipped over - typical FIA "logic". Also, what constitutes a permanent number - a single entry in WRC in one rally and you can lock that number down? For how long? Idiotic system.
I truly hope that most of the drivers in WRC will continue to choose small (2-20) numbers in general, so that entry lists don't become totally unreadable. Or that the whole system is ditched in couple of seasons time.

- Most of the stages are new, only two have remained from last year
- A couple of stages are familiar from 2014-2015
- New power stage at Calvi is familiar from IRC and seems very fast
- Long Castagniccia stage seems quite tricky and narrow
- Start, service and finish are in three different cities
So, Antti, please forgive me for a slight OT, but, as I can see, you are very much dedicated to the special stages. Can you please correct me if I'm wrong, but it seems so far we got this for 2019 season:
Monte Carlo, start: Gap, finish: Monte Carlo
Sweden, start: Karlstad, finish: Torsby
Mexico, start: Guanajuato, finish: Guanajuato
Corse, start: Porto Vecchio, finish: Calvi
Is this correct?
Correct. I think these are the only rallies where the start or finish is in a different location to the service park. In Corsica both, with service park in Bastia. In the previous years Monte Carlo also started from Monaco, and in 2017 Sardegna had a night break in Olbia. Germany 2017 also started from another city.Quote:

Gryazin testing for Corse (3 days!)
https://youtu.be/XdV5odNOcI0
Interesting that on Michelin, in the past he was on Pirelli.
Those are Sanremo stages?
according to youtube comments test was at Erli 70km southwest of Genova
I think he last year as well did all tramac events on Michelin and the others on PirelliQuote:

no, the WRC one that points to the left and the dashboard takes 60% of the screen is better...Quote:

Likely mikkelsen will be the "expert commentator" on RedBull TV for the week end. He may see the light and change career :)
It's terrible. It doesn't show any action. The promoter shouldn't consider it unless if it wants to attract new fan base.Quote:

Being installed on a helmet, if the helmet is not homologated to have that installed.Quote:

having a camera on the helmet may increase the risk of injuries, because they are not tested like that. There shouldn't be any extra unnecessary stuff on your helmet. If you remember, when Schumacher fell while skiing, there were stories that his helmet camera made it worse.
stickers can't be compared to cameras or other accessories
Best helmet camera I can remember (with a proper flat 6 soundtrack!)

you can't attach camera to the helmet, you can't glue to helmet any camera holder (by normal glue, 3M tape, etc.) it's simply like that, G-forces play here big role also I believe
The peak G-force during a crash can reach well over 100G (per time period of milliseconds or even less). GoPro weights around 0,1 kg which means at the peak acceleration the force reaches over 100N (>10 kg). This is an additional force to what your spine and muscles (with the help of HANS) have to keep in place. It's clear that ideally the weight of anything attached to your head including helmet shall be the lowest possible.
Than there is a risk that the camera gets released in an accident or due to long-term vibrations and shocks in harsh environment in terms of temperature, humidity or dust and flies like a projectile in the car.
And last but not least the camera alone can penetrate the helmet if the helmet with the camera mounted on it hits the rollcage/roof or whatever.
I would personally never wear it.
how plastic can penetrate kevlar is something that puzzles the scientists to this day...
Can't the dashboard/rollcage mounted cameras act as projectiles ?
Ask yourself whether the screws, lens, acumulator or PCB will easier brake through the rollcage tube or the helmet in the moment when they find themselves in between.Quote:

I am sure if those useless blobs of fat over at the promotion of the WRC had the energy and the will to move the sport further they could figure something out instead of the joke angles we get today.
Braking a helmet by hitting a rollcage is not that unusual (for example here: https://www.ewrc.cz/images/2009/suma...jf-crash-4.jpg ). If a camera is present on the helmet in such accident it's likely that some of it's parts penetrate into the helmet and you don't want to have metal joint or screws being pushed in your helmet by the rollcage. Moreover hitting a rollcage with the camera is far more probable than without simply because the camera takes some of the space between the helmet and the rollcage.Quote:

In case of a helmet hitting the rollcage what is moving is the whole head with the helmet and the camera together, i.e. the moving mass has roughly 6,5 kg which means that it doesn't need so high speed for similar effect (6,5 kg heavy head @ 82 km/h has the same energy as 700 grams heavy thing @ 250 km/h). The speed in which the helmet can hit the rollcage is hard to estimate but it can get close to the vehicle speed at the moment of the crash, i.e. it is not a magnitude lower than in Massa's case.
For your information a 200 grams heavy thing @ 200 km/h has a 3/4 energy of a 9 mm bullet and 1/2 more than a 0.32 ACP bullet (Škorpion submachine gun for example). That is not negligible at all like you imply.
Anyway any added weight on the head makes the risk of injury or even death higher. That's a fact hence why it's a bad idea to have a camera on the helmet no matter how well it is fixed. If there is a need for camera on the helmet than it shall be as light as possible, as small as possible and fixed on a helmet which is actually tested together with the camera.
It´s probably not the helmet hitting the rollcage. It´s the rollcage hitting the helmet. A camera made of mostly plastics seems not to be the problem when the rollcage coming with loads of G after a heavy impact.
Cameras or not - this is thread of Tour de Corse, not technical thread.
So who will win? Pickems starting in a few hours... :) :)
Sorry for off topic but You are wrong. It's the head of the occupant which keeps moving after the bodyshell/rollcage already hits the obstacle (tree, wall or whatever). This is the very basic foundation of passive safety topic. And the camera of course is a problem.Quote:

if you crash a rally car at 200km/hr on a solid object you are going to die no matter if the camera is present in the car or not... how many corners at 200 km/hr does the whole wrc have ?Quote:

comparing the energy of bullets what fly at a straight line with the forces developed in a car crash and are in multiple directions almost at the same time is beyond stupid...
i wonder why people put cameras on their helmets during testing videos...
