Theirs is HPF. means all the japanese cars are inferior to proton is it. Like vios corolla and camry are more inferior compared to protons. Serious questions. Or its just that japanese are not advertising their processing

yup,its true,bezza scored excellently in it. for iriz, it is due to mark being deduct from modifier. Im hoping they managed to rectify it in persona n iriz(facelift).

1. One of the main contributor for good crash result is the weight. Bezza is 930kg max while iriz 1180kg max. In frontal odb test, the kinetic energy come from the car itself. Crash engineer rule of thumb, 100kg reduction leads to 10% less intrusion @ firewall. Easier to get good result.
2. Engine package. The smaller the size (not cc), the better the crash result. Bezza has good engine package.
3. Crash is stochastic event, very difficult to get consistent result especially @ lower leg area. Let say you can get max 16 points in one test, you can get as low as 15.4 points in another test. So if iriz 14.07, most probably due to it is at the lowest limit (engineer task is to ensure that in the worst variation, it can still achieve the target)
4. Crash result depends on dummy calibration. For each area, head, neck, chest, femur, tibia etc there's a corridor that the dummy need to comply. let say chest deflection, you can have variations up to 6mm between dummy to another dummy. If in the test, you get dummy calibrated at the lower corridor, then you're lucky.

How do I know this? I used to worked as crash simulation engineer for audi.

For you to compare iriz and bezza result is unfair due to huge weight difference, this has been explained in NCAP FAQ. In high speed collision between both car, bezza has less chance to survive. Bezza has max 590MPa steel, iriz has countless 590MPa, a few 780,980,1180MPa parts with a couple of 1470MPa grade of hot formed steel

later accident cannot save people inside, coz bomba lmbt potong.. owaiiii

HPF is ULTRA HIGH STRENGTH STELL (UHSS). When people talk about numbers like 590, 780, 1000, 1200.....that is tensile strength, not their hardness (Hv). HPF can be fabricate with 900 tensile strength and have >500Hv level. That is some tough stuff.

Bezza max tensile is 590. They scored high ASEAN NCAP because of their small engine, which create more space in the engine room, thus during frontal impact, their small engine have less intrusion into cabin + Active Safety features (which if we remove from the package on the lower line, you basically exposed to serious injury)

it's good to see proton is getting serious on safety.
heck they can even become somesort like a volvo of asia if they want.
become obsessed with safety like volvo until make cars with super hard body shell using boron steel.

If say between a 2-airbag Iriz and 2-airbag Bezza, which do you think would fare better in a side impact?

Maybe Volvo of Malaysia, if want to say Asia is too wide.. Subaru already been knew as Japanese Volvo at oversea.. Still Proton still a long way to go.. 6 Air-bags and VSC is a normal in the past.. Now people are gunning Emergency Automated Brake system, lane departure system  or Automated Driving System.. Previously if not mistaken Proton got work with LG (google: Proton Iriz prototype fitted with LG ADAS camera).. But where is the result... 

The japanese may use UHSS up to 1000-1300mpa. It can achieve similar strength level like HPF steel, but at the expense of weight.

Lets say a vios head on collision with an iriz. Who suffers more

1. Have you seen the 360 videos right? There is CAE analysis video of side impact. The intrusion were targeted at b pillar lower area. This means less intrusion at the chest and pelvic area. That should indicate a very good side impact result even without side and curtain airbag. Mind you that iriz use HPF grade for side impact.

2. Bezza has the advantage also, being lightweight, the inertia of the whole vehicle is less than iriz. But Bezza only use max 590MPa (advance high strength steel), the rest 270MPa (mild steel), 340MPa and 440MPa (high strength steel)
I manage to find a picture of bezza body in white. From the picture it is hard to imagine what type of material that they use. The color code is probably not indicate material, but crash load path (front, side etc)

So who knows, unless they test the car and publish the result

In term of frontal crash, it would be equal bcoz bezza small engine+large engine clearance & iriz UHSS.
but if we measure on crash worthiness, iriz & new persona win because their UHSS are well-positioned in all critical area of the body (Front Pillars, Side Members, Center Pillars). I believe new Persona also have HPF on B-Pillar (Center Pillar) for side impact like Iriz

lel...
anything with potong sure discussion up to engineer level
meanwhile.other model
no fuk safety is given. sales like pisang goreng fireworks. haha
