Erebus Driver Safety E-Cell

Could this become standard equipment. Will be interesting to see if the seat manufacturers step their game. Costs way more?

Wayyyyyyyyy more expensive, but really, who cares? It's a key safety item and not the area to cut corners.

Highlights safety deficit in Utes and what CAMS/FIA hasn't done to protect sport since Brock was killed.

The re-design of the side intrusion, which has largely remained unchanged on the COTF chassis does not appear to be as effective as one would hope.

The move to the E-Cell might be a good idea.

peckstar has a lot of promise if they can keep it on the circuit!
however the side intrusion hold up well today. In what was a pretty extreme example

I dont think it would have done that as well in previous versions

For sure, it's an improvement. But with the concept of efficient driver changes, and the requirement for functioning doors, it's still a compromised design. The NASCAR solution is probably the best idea for a tin top.

For those experienced in cage design, why wouldn't V8SC have specified NASCAR-style door bars for the driver's side? Must be a good technical reason they prefer the cross bar design. Can't just be about driver change efficiency (I hope!!!)

The current design is half-half.

V at the top, NASCAR-ish at the bottom.

The incident in question saw a fair portion of a substantial part of the #34 car, i.e. the left rear wheel assembly, penetrate the apature where the driver enters and exits the confines of the roll cage.

The essence of V8SC racing is the two-driver endurance races. Making the apature smaller may be detrimental to the endurance concept. Mr Stuart of SBR/Erebus made mention in a recent video clip, that the implementation the E-Cell did in fact hamper the efficiency of driver changes, but in my opinion, it would be a compromise the whole field would accept.

I may be mistaken but I thought I saw a pic of the inside of the car and it shows the rollcage sideintrusion bars broke around 2 inches from where the cross is welded in.... I wouldn't say it held up "well"

I was a little shocked to see the bars had just sjeered off where the support gussets are welded on. It's hard to say how good or bad it was though, as that impact was something seldom seen. All in all, we easily could have seen a very serious injury yesterday and for Courtney to have walked away from that collision I think it could have been a far worse situation.

If teams are bringing in ground breaking safety technology that only 3 cars on the grid are using, that has been proven, you would think the category would mandate its use though.

Since the introduction of COTF was supposed to make the cars safer I was surprised that the door bars dont curve out more. At present there is nothing absorbing energy in the door. It would just be another way to get the driver away from the accident a bit more. Or how about a 50mm thick aluminium honeycomb panel?

I acknowledge that JC accident was big but with any impact you need something to absorb the energy. Air does not work.

Apparently they do have a honeycomb insert in the door.

Other FIA stuff like WRC, has two tubes bent in a V, and welded together in the centre to form the X. The placement of the centre of the X is virtually inside the door cavity in some cases. This sees a big improvement in energy absorbtion in side impacts.

Just take a look at the V8Utes.... or what has CAMS done in rallying since Brock was killed....

Some times engineers say that the cage done its job, absorbing the impact, even if it breaks... they all have max load they are designed for. Doubt cage break is a build fault.

V8SC passenger side is better that FIA spec, drivers side cage further exceeds that. Just look at a WRC 2013 or GT3 compared V8SC CoF. Bizarrely the FIA haven't beefed up roll cage spec' after the FIA Institute did crash testing for CoF.

They've had the door honeycomb for more than a couple of years. Some WRC cars have impact absorbing foam in the doors. NASCAR has 6 inchs of impact absorbing foam outside the cage.

Maybe should have layer of foam on inside of cage along drivers legs

Looks even worse!!!!!!!
