So glad that you guys made it through without much worse injuries.....god was watching ❤️🇺🇲

There use to be a drop down from the pavement to the ground but now the ground is level with pavement so you don’t have anything to hold you on that side of road and the rest is physics

Vermont maple trees don't budge.

I live 10 miles away and enjoy a cigar after a Ducati ride to the top.

Excellent presentation. I have seen many racing accidents and hear about improvements post accident review, but not to the detail that you provided. Great work

Fascinating Frightening Impressive how much energy and damage that car absorbed. The engineering that goes into safety cages is also impressive. I dont know why I was fed this video other than I'm a heavy truck driver, and a fan of machinery in general. Very clear information

Hope the driver & co-driver had complete recoveries. While broken bones hurt, very impressed with the fact your lives were never in peril during the crash & rescue. Things didn't go perfectly, but they could have gone so much worse. Thankful no fire with the damage to the fire suppressant activation cables. Take care, good luck going forward.

great information very informative

Good you see you are ok-ish. That had to hurt for the next week.

Nice work Margaret

We need to redesign the way that we bolt the restraints, if the only saving grace to the frame was the plate used to hold the restraint, what will happen to the occupants when the impact is larger and the bolt and plate are incapable of holding the forces involved?

Co-driver needs a grab bar, not arm restraints

I hope both of you have had as uneventful a recovery as possible! Thank you for sharing this analysis!

What an amazing comprehensive breakdown & analysis. This generosity will benefit many for years to come. Bravo!

That's great analysis. You guys are lucky to be here. I'm interested in your analysis of the broken clavicle and your opinion that the same outcome would likely have resulted from a hybrid device. I have a different opinion that may be worthwhile for a medical student to consider... Is it possible that it was not the weight of the unrestrained arm that caused the break? I think that the angle of the seat in a rally car being much more upright than in a formula car changes the direction of the forces in an impact... In a rally car, with the HANS device, the weight of the head and helmet moving forward is opposed by the lower braces of the device with the top of the shoulders being the pivot point. In a formula car, because the body angle is much more prostrate, those forces have less opportunity to break the clavicle because they act in a different angle. For this reason I think that it is possible that the hybrid device might not have resulted in this injury. Worth discussing.

great analisys, sorry for your injuries and for that nice car

A well explained video glad both were ok it looked very messy

I really must commend you for conducting the thoroughly objective investigation and the further investment of preparing the video to share the analysis/lessons learned. It's invaluable. The inevitable emotional impact that accompanies such an incident is invisible and too often goes unspoken. The quality of the content is remarkable under the circumstances. Chapeau! I send my wishes for a speedy and thorough recovery re: both the physical injuries (driver/co-driver) and emotional impacts (the entire team and their families).

Very good and informative video. Any reasons why king brand in particular? I find it interesting being from Australia I assumed a product from Europe or the US would be higher quality or better in some way.. lol

amazing safety cage to protect the driver & passenger , after the crash , great unraveling and future planning . Wish well on healing of both occupants

So glad you lived to tell the tale Thank you so much for sharing So much work gone into this car to make safe and you needed all of it.

Hey there really good video about something we all fear, but need to learn from, quick question the seat mounts, bolted from seat to floor bars , where they Aluminum and was there any damage to those ? Seat mounts are under review here in New Zealand, so real world information is the best information, so any news would be appreciated

CHEERS from AUSTRALIA

Glad everyone was safe very good summary of this incident especially important for fabrication of a safer vehicle

That was one helluva shunt. While I'm sure neither occupant is particularly happy with their injuries, that could've been a LOT worse. There definitely was a touch of bad luck in the way that the framerail just missed the tree, as, had it been more involved in the impact, it would've allowed any inbuilt crumple zones to aid in the energy dissipation. Thankfully, some VERY nice design on the cage saved the day. About the only thing I would've questioned was the use of the full dashboard, and the dash support not being integrated into the cage. As you've learned, while a full dash can look nice, they can be a royal PITA when things go wrong. Something more minimal & better padded might be a consideration for the next car (regulations permitting). Similarly, some padded panels covering the cage forward of the seats might be worth adding. Nothing too complicated, just some 5mm high density foam on a FRP/ally panel to spread any impacts with the door bars over a wider area. Other than that, it might be worth checking with the Fire Crews if there are any nationally recognized ways to identify fuel lines - specific colors or patterns that any Fire Crew would see & automatically know what they are looking at. IDK if there are, but between air safety standards, railroad safety standards, commercial vehicle safety standards, and the like, I wouldn't be surprised to find some way that they already know to identify fuel lines. Well, there's my thoughts. Good luck on the rebuild...

Wow, what a major off! Glad it wasn’t worse and hope for quick recovery. Very interesting and thorough analysis

Glad everyone is ok and good info on the rollcages

One of the most interesting things I’ve seen on KZfaq for a very long time. This sort of analysis is invaluable and I have no doubt that it has a place in learning for those who prepare and compete in rally cars and also for rescue and recovery guys in relation to how they train and the types of less common obstacles that were encountered.

Thanks

How are you sure that when unscrewing the nut to remove the wheel you are not unscrewing the same time and the stud given that the stud is torqued with less power than the nut

Wow!

Man that's a heavy impact!!

Great information and very well put together documentary. Glad you both lived to tell a tale. It's amazing how strong those subframe chassis are, and I know because I've used an excavator to straighten them. The machine is lifted off the ground whilst pulling in different directions. I broke a half-inch thick chain as well. Maybe try circuit racing next. There's usually no trees to stop you!

Given the inputs, surface and speed compared to the earlier run, it almost looks like a mechanical failure more than driver error. Glad you two are going to be OK. Thanks for sharing. The community benefits from the occasional reality check and analysis.

What harnesses are those?

An extremely hard hit. I am glad you are (mostly) ok. Thank you for sharing this breakdown. This is exactly what every team needs to think about when building a car or racing

😮 glad your hear to tell the story buddy. That's a rough one

We learn from history! Worth colour coding, fuel lines, brake lines, water lines as internationally recognised. Harnesses have become wider to spread the loads and they also give. That is why the belts should be regularly changed in rally cars. That was a hard bump but glad all turns out ok.

Glad you are ok, thank you for this very well made video. This is real advice which can help keep everyone safer. This could even save someone's life

Great video! Glad to see everyone will make a full recovery 🙏

But will it buff out?

Loved seeing this car around, my personal favorite at the Climb to the Clouds events. Hope the heeling process and everything goes smoothly. Great informational video about the accident and lots of safety pointers a details.

Incredibly well researched write-up, thanks Manu. Do you think the data was lost on the Cobb unit or do you think reattaching the chip would provide any useful information?

This video should be required viewing for all safety workers, race car builders, and drivers. Thank you Emmanuel for this production and wishing you a swift recovery.

Autopsie méticuleuse d'une accident brutale . Cette vidéo risque d'être utilisé dans des formations de secours/motorsports pour des années à venir . Méthodique comme toujours . Bravo !

I know nothing about the data recorder and how it stores data and if it is doing it real time or caching it, but it may be possible to have it repaired and the data recovered. There are many business that offer that kind of service.

I really appreciate the detailed analysis & your openness in posting this. This provides a great leaning opportunity for many different groups. Thank You

Thank you for the detailed analysis, very educational!

Great learning material!

Hopping for speedy recoveries glad both are in good spirits!
