From pure technical point of view (i.e. disregarding the tech regs), in theory yes, but in practice very unlikely, as the current state of the readily available structural foams is such that their...

Went through the rules (or what is publicly available) and can't see a ban on MMC. Actually, as is usual, the rules are very badly written talking about where "composite material" is allowed,...

Thanks racerx1979, I am happy to leave it at this.

All good reads, thanks racerx1979.
For clarity I should point out that race car suspension component design is part of my daily job.
In general anodizing (either of the hard or decorative kind) is...

ESTR - very simple - the suspension did not see loads exceeding its envelope :)

racerx1979 - I would be very surprised if the colour comes from hard anodizing rather than shot peening. Structural...

Going back to the Hyundai upright failures and looking at them from structural point of view rather than drivers' errors, I was wondering where do the rules stand on MMC (metal matrix composites)? I...

Thanks Jan, I am aware of these facts and vehicles. To clarify what I meant by “from the ground up”, for me it is when the designers are given “clean sheet of paper” (or a “blank screen” these days)...

Hi Jan, no need to shout, I am very happy to clarify what I meant - you quoted the last 50 years - would you list all the rally cars that have been designed from the ground up as rally cars, i.e. not...

All good points Jan.
On another note, although probably nobody cares, but to correct myself, I mentioned the Beta Montecarlo Turbo as not being constrained to the use of Macpherson strut suspension...

Itix and Mirek - good assessment of the pros and cons of the double wishbone vs Macpherson strut suspensions.
Given sufficient space and provided it is allowed by the regs (i.e. car does not have to...

Hi boys and girls, haven’t been able to post in a very long time, but was able to enjoy Rally Germany and was happy to see that the doom and gloom predictions for a dull 2017 course proved to be very...

I wouldn't be surprised if the answer to this question is no due to the homologation regulations.

Watching Rally Finland SS1 and it is incredible to see how flexible the Citroen diffuser streaks are (topic discussed previously), flapping about a lot, good views at 17:17, 26:17 and 33:40.

Thanks Mirek, so hard working it is then.

Once again very helpful insight. Also very interesting what you are saying about the gurneys - should we assume the same applies to the wing trailing edges? And even more to the point, presumably the...

Thanks for the insight Mrpengski, this is really appreciated - you are quite right, there was so much discussion about the damage all these fins will suffer and yet it is not really happening.

On...

Citroen keep persevering with their "nice" lift creating mud flaps in front of the rear wheels, only team to do so, I find this very peculiar:
...

Yes, cracks in carbon fibre parts are more challenging to detect and properly assess, it usually involves ultrasound inspection (more commonly) or CT scans (computerised tomography - more rarely in...

The reasons for the failure would be any one of these:
1. Design does not account for ultimate loads encountered in service.
2. As above but in respect to fatigue loads.
3. Material batch problem....

racerx1979 is right, the centre one has the right size pipe for an intercooler (interestingly it is an air-to-air one), while the hoses on the two radiators either side are the right size for the...

Looking at the image below, I can't see mud flaps in front of the rear wheels:

Actually to add to my post above, the mud guards in front of the wheels are not part of the FIA requirements as far as I can see.

Correct. I was just pointing out to the fact that they are testing without them, no doubt in pursuit of finding some answers.

Wrc2017 – wheel cambers: yes, the positive cambers in full droop are inevitable consequence of the type of suspension used, but there are some differences between the teams, which I would like to...

The only thing that would give you the optimum grip for each wheel in all conditions (short of using one electrical motor per wheel) is a transmission consisting of one clutch pack per wheel with...
