haiya, i thought everybody already know, even in full manual mode, by push lever to tiptronic side, the max engine rev is at 5k rpm lor, so, it give u a bit room for overrev a bit, which not good, overrev, wasted energy. The cvt limit is at 5700rpm, so, it will upshift automatically when u r overreving the engine, its the cvt characteristic by the way n also will downshift automatically around 2k rpm to 1.4k rpm depend on which gear it is on during that time.

nw i wonder how the proton to test the 0-100 and get the 9.6sec result?since i oledi use D drive,and never rev more than 4k rpm(never over the max torque rpm range),0-90 oledi need around 10-11sec(wit aircond on and 3 person in car)..or the proton test wit paddle shift or s mode?

Erm, u said the weight of 3 people around 190, so minus 70kg driver, so left 120kg. 120kg+1340kg means 1460kg of g force(ha..ha..)which means u r drivng the car with around 20kg less then exora bold cfe kerb weight coz already minus 70kg for driver. Exora cfe around 11.3 scd century sprint while u get around 10-11 scnd to 90, so, not that far.

Which means still the cfe still give same performance as in bold coz the weight is nearly the same now with occupant.

Dunno about u guys, but for me its the same based on the timing, maybe just feeling, he...he...sory,i like to laugh coz im a happy person, n im not datuk. But r u sure the test drive car is not the one being abuse by someone before doing drifting@full dougnut last nite...:-). Just kidding.

U all knowla how abusive people can be. Still remember abuse altis until the glove box come down when entering apex coz driving hard but really hate the esp interfere too early, n the door panel rattles. But then, its a good car, i mean altis,just maybe many already abuse like me, but based on chat with sa, its like me the only one, coz he said, abg bwk kete bleh tahan gak, causing him wearing seatbelt from being as usual typical malaysian, seatbelt is for cosmetic n just keep quiet the whole journey :-)

ha..ha.. Its a test drive, so, dont worry,just do what u want, just dont accident or masuk longkang udahler deme.

gudmorning everyone. Did some questioning on sluggish things to my friends, so, technically, even me pening, but try to lay out as simple as i understand.

Whats so much diff in cfe exora n preve throttle response?
Exora bold throttle is sharpen a bit as to counter its weight. While preve being lighter, throttle in d mode is not as sharper as in exora.
This sluggish feeling associate with dbw n cvt clutch based. If torque converter based cvt, normal auto, its not that apparent, but still have lag.
From stagnant, in d mode, is like throttle input ratio changes from 50:50 to 70:30 before its start to become better. It is due to emmision control n safety reason. Its like this. If throttle given out 100% input, its like driving manual car without dbw throttle, rev up to for example 2k rpm where the turbine already spin, lift of clucth, the car will instant lurk forward n n cause wheel spinning or a bit torque steer which is dangerous coz dbw if in full throttle, is very instance. N to control amount of harmful gas emit immediately, so that can reach euro step.

So, its even from stagnant rev up to 2k, turbo still not spooling yet cause throttle still not 100%, until start moving then gradually the throttle change to max ratio, turbine will spooling.

While in S mode, throttle being sharper about 20% from d mode n also rpm also raised 20% from normal d mode, so, u have better throttle response than d mode during stagnant.

Being tuned to be more linear, he used the word refine, the surge is not as strong as bold cfe, but its actually the same.

If used torque converter based, still has lag but then its better, but during moving, pwrloss is higher than clutch based. Same as dsg. Only from standstill to move only. It just a blink of a second. More common term is call throttle lag.

So, he advised, try to go for a second spin. If want to immitate a normal sedate citu driving, rev up a bit like 2k rpm, when the car is already on the move, then ease off a bit the throttle to avoid 2k rpm to have better fc relying on cvvt.

Even when want to take out for sprint, rev up, still feeling slow when start coz of the above mentioned but when it catch up speed, throttle in full,then its ok, when u rev example 3.5k rpm from stagnant, when moving then continue to pressing pedal to reach 4k rpm.

So, i dunno whether my layman explanation is understandable coz cant explain in tech things coz me oso pening :-).

But coz me so used to all prtns using dbw whether from prtn or renault previously, so, dont have any probs.

Maybe everyone shud take a second spin.

ha..ha...elantra using torque converter based auto, already mentioned is better, same as cvt torque converter based.

Is not burning fuel too much since rev up to 2k rpm since throttle input is not 100%.

When the tyres already rolls, its not a problem, is cfe gimmic or something, still give u the same as 2.0, just initial, doesnt means when on the move,its not slow.

Is it really the diff between 2.0 n 1.6 is based on 0-5kmh or 0-100kmh or 0-10 metres length is the measurement of engine? If yes, then, preve is bad then. No harm done.

Prevention for upshift n downshift, yes, depend on virtually gears, not the same for every gear.

I dunno, but feedback from journo, that is not a prob, the only thing they ask is about the surge when enter the tubo one is not as powerfull as in exora bold.

But then, everyone has their own perception n opinion, so, is not rite or wrong here coz no one wrong here.

Just try to help giving info, if u said bad, then bad. Its not wrong. As far as ive been informed, everything already taken into account on tuning.So, happy motoring :-)

in cvt, what kristof said is known as creep function. Where clutch pressure is maintain to initiate forward movement when brake pedal is release. There also crawler function n pull-away(set off), slow sat mode when full throttle application to name a few. Some functions are to assist n for safety reasons.

and safety means safety on driving behaviour n situation, safety to powettrain(engine) n driveterrain(cvt).

If it means easily accident, then, many cvt's cars user already involve in accidents.

Every engine, every trans has its own pros n cons. There is no best trans in the world, if u said dsg, just google the probs n troublesome for dsg, or even manuals has diff characteristics. Try out getrag one, mitsu one n aichikikai one in prtn's,they are all diff. By the way, if not mistaken flx se manual already on sale but still dont see any marketing of it, maybe overshadow by preve launching.

Aiyo abg, prtn mane ader issue official statement 5 stars ANCAP, prtn issue preve design to MEET 5 stars NCAP by doing various testing according to ncap(whether euro@auncap) procedures n more that is under unece procedures, thatchams, adr n many more.

Aiyo, already tarnish the name before arrived there :-). Whay u heard is unofficial statement by somebody on the net.

Yup, not soo good coz not well equips. But then, try checking frontal n side impact scores for well equip cerato forte or rondo. Maybe give u some hint.

people keep thinking coz prtn cap ayam, like china brand, not china made underlicensed.

Ecu update, reflash n etc, is common. Even for famous tsi n dsg, even changing design, updating material n etc. It is all over the world, common things among manufacturer. When its not related to safety, rarely doing announcement for recall. Just updating during service n even by letter.

Not all discomfort appear during testing. When complaining,its standard across all manufacturer to inspect first, determined whether all are affected n whether just few isolated case. Everything need to check, is it the product, the design or even causing by human factor, then, after inspecting, countermeasure been table, tested first whether it solved the probs or not, before handed in back to customers. All things need to sort out between manufacturers n vendors such punch as oem for driveterrain, ecu by conti ag, turbo by borgwagner n etc.

Sometimes, it just one bad part among thousands. So, its not design probs, not really part probs. Sometimes, its not a probs, just diff characteristics. Thats why experienced testers who test so many cars like journo, sometimes dont even mentioned it coz it is normal. Many cars have the same characteristics, so, why become a probs when it comes to prtn.

All i can see is becoz prtn is being associate with cap ayam. Thats all. Thats why all the slamming appears to all prtns showroom, n rarely happened to others.

I dunno whehther u have seen this or not, but as my observation, rarely seen people even crawling to peek under the cars in other showrooms, but common things in prtn. Even for preve.

Just heard someone investigate the multilink system to search for the strut bar. Even some thats trying gores n menang method, n knocking method. Do u know how strong is the metal by knocking? If pedded a soft steel with dampening, it sound solid.

Thats why in prtn, crumple zone is known as tin milo. But other makes, wow, thats a good crumple zone. Same as start push button n etc, even the fonts becomes a debating topic. Neverheard this font topic on other makes when introducing push start button :-).

just saw one, overall very nice car for 72k

but the problem that i noticed is with the auto light and rain sensor, it is way too big till it causes vision problems

also, the glovebox needs to redesign, i knw why it breaks. plus the driver's compartment, below the steering has issues with opening and closing. feels like it is going to snap off in a moment.

did i miss something,which glovebox break? This thread is too fast to catch up

the reminder@indicator is normally place in info display, but its good to put reminder to passenger side so that the passenger also being remind if not fasten seatbelt, airbag is off. Part of meeting 5 star, the safety reminder. The unlock is for passenger for easyness to unlock the door. The driver's side also has one on the door panel if not mistaken. Only part that involve driver such esc n heating elements on the right side of h u. Isn't it ergonomics or not?

The design, i think just to make it nice flowing with right n left side. It will be explained by sa(they shud do when u test drive the car), but dont worry, normal things to proton, everything need to scrutinised or molest or abuse 1st to check quality. If u just touch nicely n push even the indicator nicely, then not a prob at all. Probs when u push with force,like something rosak.

Its under unece n euroncap rules to have reminder.

But i think its ok, maybe they need to design it diff so that people wont misunderstand(but the owner wont coz they will be informed about all functions).

i think u can close it without pull the latch. Somebody already pointed out it was the same mechanism used for golf, then why become a prob in prtn? Maybe becoz those interested in golf a nice n gentle one, just maybe...

Actually, dontlike the close compartment under the driver's side. But i think they dont want to make it open just like saga. If closed, can hide things. But agree on it shud be smooth operator. I think they will fine tune it for production.

60 designers from prtn,italdesign,lotus, magna steyr sits together on designing, and they found mutual agreement. But i know, some may likes n dislikes. But they are doing the best. Opting the best materials within the budget, sub 80k in malaysia, equip with textured soft plastic on important touch point, its creditable job, even some says cheap when its not cheap, thats why only certain segment japs n koreans have it(but korenas nowadays really good in playing with materials).

Germans, look at the price. People accept its coz its reputable brand,so justify the price, its like pitting polo with global yaris. Check the price,check the equipments offer, check the interior materials, then u know which one better. Both has strength n weakness. But people buy both coz both brands are good.

Prtn, always been underated brand even already push the product to the limits.

But they are trying hard nowadays. Thats why u have names like sid, protronic, ress and prtn ride n handling coz its one way of uplift the brand.

Yep, some says marketing gimmic, but toyota say goa, everybody gaga n whoa, n goa just the name, n its not the same for every product, not all goa 5 star.

i already mentioned earlier from the 1st thread, im not protonians but i know some of them reading the forums on the net silently.
I think so many times i stated this :-), sometimes kinda weary n tired , hu...hu...

I think they will take note when preve sell all over its target market coz every opinion takes into account, not just malaysian. Same thing when the make the design, based on market survey i think nearly 26 markets that they target to sell preve. If not, u wont have the steering emblem, the teh tarik hook, soft touch material, intergrated gps, esp,tc, multilink, paddle shift the price that people willing to pay for it n many more. Thats what i heard.

off topic, just insigt, polo sedan, 1.6 mpi, 77kw 5250rpm, 153nm 3800rpm, euro step 2 engine(lucky for us, our g still implement euro 2, if not it will be pricier with tsi), 6 speed auto tip tronic. With using tip tronic, century sprint 12.3 scnd, weight 1182kg, wheel base 2552, dimension, 4384L/1699W/1466H. Combined fc 6.5/L 100km, urban 8.6L/100km, all fc get by using tiptronic function.
4 airbags, abs n ebd.

The best part full digital a/c, he...he...price...100k+-, more or less. For sure less than polo.

Hu...hu... Just trolling...

That is what called afta, foreign as asean made being tax same as locals, not more, not less. U think afta means no tax lor??? :-). Afta means no import tax to asean, but local tax as being tax to local still applied.
