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.

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.

they have actually,during preve,suprima,iriz,but persona i think will come later when they called up the media for media drive in open road,rather than tracks. even during exora,they also explain it.

This is just my own opinion, for general public, we can say it strong,we can put figures 1500mpa n etc,but the question still remains,how strong it is? unless u r car enthusiast or have engineering background,then it shudnt be a problem. But for general public, they need to see something that easier to comprehend and you have only 2 minutes to explain in a short video.

htss or uhtss always appear in any car launching in malaysia,but what make proton diff then?

and it also to show the improvement proton has made from old model to the newer one. if talking about uhtss,what a fuss about that,gen 2 already use it eventhough minimum. That is what it means he evolution from old persona to new persona.

i believe its clearly evidence in the video, from mild steel being process using hpf method create stronger material, it stated 5 times,but anyone can write that.

like 5 star ncap,eventhough ita already stated 5 star ncap,general public will question,just 64kmh,48kmh,56kmh,35kmh,just hitting barrier,not hitting an actual car n bla bla bla,n it only be prove when actually accident happened,after then people will say,oic,thats why its 5 star,thats why its strong n etc.

but make a teaser video showing real accident isnt really good for launching/traser of a new car(eventhough its being used prev,but not video,with consent of the owner).

how many times u still hearing tin milo of proton cars,even its not tin milo to begin with. since gen2,proton has started use htss n slowly use uhtss(roll forming uhtss for side beam impact),n still u can hear it now even during persona launch.

general public isnt like lowyat forum. safety never been 1st things in their mind,so,it is a part of safety education.

if not,since gen 2 they already know and understand it.

as i mentioned previously,i dont care about proton sales cuz im not selling proton cars or what ever cars. i just want them to improve,be better,and sometimes improvement need to be told,or people wont realise that. even being told, it is still unheard.

same as bcm. so many technical things being highlighted during exora launch,but many dont realise it. thats why now they just simplify things,hopefully it reach the public in general.

and for techie part,i think upcoming media drive will explain what matter most for those who do understand those techie part.

i just pity those in rnd, they work their ass out despite a lot of limitations especially on budgets n man power. Those otai2 in rnd already flock to bigger companies. They need to be highlighted nd to be heard, its the 1st time if i can recall,their work behind the scene being put in video teasers.

If not,just faz & fairuz,which you know it just an ads,like any others ads.

im deeply sorry for long comment.
