Is NCAP testing a comprehensive test of a car's survival and also the occupants inside it ?
Probably NO !!!!!!!!!
?
Its an indication but IMHO, like all tests/legastlative things that come from the EU its a very biased and misrepresentative that favours the sort of car the EU wants us to buy (low CO2 french made cr4ppers). Like for like NCAP is useful and I used to put a lot of weight on it, but not so sure now. Look at a 202 vs 204 and you can see how modern cars have progressed but a 4* Q7 or a 5* Fiat 500. Q7 atomises the 500 so the test is flawed.
I think this because
1) The test is only carried out at 40mph. This is far to slow. A small hatchback can now complete with a large saloon with a frontal impact in this regard and I admit thats a credit to the makers of small cars, but I'd like to see a test for a higher speed (120kmph-75mph) impact too and lets separate the men from the boys.
2) I think rear collisions are important and how are these measured. Smaller cars put the rear passangers perilously close to the rear of the car making them very vulnerable. In an E class (211) not so. In Pontoneers 126 not so, in an Toyota Iq inches so.
3) Roll over test, would be nice to have one and would favour better made cars but probably not SUVs due to the greater mass being exerted on the A and B posts but a useful test.
4) Points are awarded for padestrian safety. Soon NCAP will do an overall score which includes this. A padestrian friendly car may not be so safe for those who are in it, but it could outscore a occupant safer car with crap padestrian safety. Don't know about the rest of the members on here but padestrian safety is not a consideration when I buy I car. I trust myself not to ram into people and would rather be safer when someone rams into me. Small eco boxes with sloping bonnets fare well, Audis Q7 not so well.
5) points are awarded for frivalrous things like seat belt reminders, air bag stickers. Good for racking up NCAP points, but doubt the sticker will save you if you stick it into a barrier at 100mph.
