Not bad

They are using UHSS on exora before Preve. A mixed of UHSS+HSS.

The point of HPF process, is to achieve similar level of strength like UHSS, without adding more metal.

To add, the Persona 2016 have 8 HPF parts.

dia cakap 1 ...maybe uphill? lolx 1:50

see your mata tajam or not

dunno ..but 508 and teana enough to secure 5 stars ..just like what uncle said ..janji 5 bintang

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

u stupiak dengar aja orang cakap. bodo piang.

he claim he is sifu + from the star ma

as i said to earlier reply ..look carefully on his video

HPF just to avoid driver/passenger cockpit from deformed. NCAP test based on sensor from dummy inside the car. Iriz score low not because of HPF but sensor detect leg area of dummy get damage signal by those part from engine bay/dashboard. Remember bout Aussie Accord got 4 star ANCAP later Honda make adjustment to get 5 star.

since when did they manage to cut cost with each car they build? if they did . they wont lose 1.6bil building 100k cars right? i.e. 16k per car in losses.

uhtss can be from 550mpa above. depend on method and type of steels used. hpf is a method use to form uhtss.

for proton,hpf method around 1500mpa, roll forming method around 900 to 1200mpa. thats what ive been informed. it has been used since preve onwards.

Hahahaha whats with you and your anti with jazz since the thread bezza vs jazz in which you argued with a fellow /k

Hahahaha
Just having fun bro

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).

The importance of hard shell/cage,when it is tested in frontal under-ride, front pole,30 degree oblique,side pole and dynamic roll over,dynamic rear impact and full frontal fix barrier like adr 69/00.

thats why the video 360 showing front underride crash,rather than 40% odb frontal crash test.

that is the info i got.

Is this why bezza has excessively long foot well?

I think it's the dashboard though, the iriz has a very hard plastic underneath the steering that limit the space for look perhaps? That annoyed the hell out of me.

ur life must be very boring. they are just joking around with the mannequin. it is not even a true crash test dummy. who drives a mannequin around a chassis assembly plant on a golf cart.

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.

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
