Darwin award nominees and IVA
Slimy38 - 30/6/18 at 04:32 PM

Inspired by a certain rough made chassis recently mentioned on here, I have a question about the IVA. In the case of the chassis I would hope/expect the inspector to fail the work. But are there other circumstances where a vehicle might be 100% IVA compliant but still utterly dangerous?

For example, if I put a 1000BHP engine in a locost, and then gave it austin mini brakes, would that actually fail IVA? Assuming that the brakes themselves are in perfect working order and fully IVA compliant, just woefully inadequate for the car/engine/missile they're attached to.

I guess a rollbar not being mandatory is a similar thing, not necessarily illegal but an extremely risky thing to leave out.

I have to admit I can't think of many circumstances where IVA and Darwin (hence the title) are on opposite sides of the coin.

There have been cases where a design has failed IVA - a while back some company made a monocoque chassis (Robin Hood?) and the inspectors said 'no way'. I'm quite sure they'd also reject any design where the 'infrastructure' (chassis, brakes, suspension, etc) wasn't good enough to match a powerful engine.

They do have a "fail all" to fall back on as they can fail a vehicle for being "a danger to the driver or other road users" or similar wording

Recalling that for SVA the tyres could be bald as long as they were correctly rated

The Robin Hood in question was the “Lightweight” an aluminium track only design. The particular one tested was not constructed to the manufacturers design, it was not bonded and had rivets missing from pre-drilled holes. It was right it failed I A and I applauded the testers from doing so however it made this model difficult to get passed.
One determined owner heavily modified the suspension points and some other areas and successfully got several through IVA.
Don’t forget the original steel Robin Hood monocoques pass with ease as did the Quantum.
