Just now compare preve with suprima . I found out 1 weird thing, is about the "Hill-Hold Assist". I check on the preve spec don't have this kind of function. Sound like the car will roll back from the hill if no accelerate ? Have anyone having this issue ?

Preve don't have hill assist.

Really scary, cant believe a c-segment car don't have this kind of service. Very disappointed  shocking.gif  sad.gif  cry.gif  shakehead.gif

Why? Hill Assist only recently became available in lower end C-segments. Just use the handbrake unless you fail the slope section of your driving test.

oh, if this is the function u mean, is it like when we stuck in the q at most shopping complex parking lane ? if that is the case, i think mostly all auto will hv no issue but manual got ?
*
Most torque converters AT cars will have no problem, unless the slope is very steep. But Preve uses a clutch instead of a torque converter, and the rollback occurs if the clutch is not yet fully close or not closed with enough pressure.

QUOTE(:3mushy:3 @ Jun 4 2014, 04:33 PM)
Yeah, usually the slope is not that steep. But one who has never driven manual car will never know the experience of balancing the clutch and accelerate pedals laugh.gif
*
Proton's CVT uses a clutch like a manual car, but the difference with a manual car is that the clutch is controlled by computer, not a human. Therefore it is difficult to balance the car on throttle and clutch.

Truth be told, the Preve NEEDS hill assist function more than any other torque converter ATs because of this reason.

I am averaging 8.5 to 8.6L/100KM (18c/KM) for city drive. Highway drive 6.1L/100KM (12.8c/KM), so far I only drove once long distance so lack of better fuel economy.

From what I kept reading about Suprima/Preve/Exora FC....yours seem to be the exception than the norm sweat.gif

maybe he very conservative on boosting? just cruising or something with the turbo still helping on improving efficiency (it works all the time anyways)

then again, he is getting his FC being better than proton's ratings (using suprima, since preve ver is their marketing highway BS ratings, like the inspira one anyways), not to mention using something like xw50 synthium 1000, i am casting huge doubts lol...

or maybe he really drive very unkerly la, which is still very possible, considering i manage to get between 11-12km/l in traffic jam (yeah, i save more fuel while stuck in a jam rofl) and i did pulled a 18km/l which far exceeded proton's overrated ratings laugh.gif
*
Deswai I say he is the exception. Not many Preve owners drive like he does, most of them also komplen high FC.

dear sifu's in preve executive there is S mode and SAT button. May I know what's the use?
*
S = lowers your gear ratio and keeps your RPM high. Useful when you need more torque which is present in the higher RPM range.

SAT = Stepped Auto Transmission. The CVT will simulate a 6-speed automatic, so instead of smooth CVT shifting you will feel the gearbox shifting from one gear to another, like a normal automatic gearbox.

when to use S mode then? can tell in details. abit noob

SAT to use for when then? advisable to use on which situation?
*
S mode is usually for climbing hills where you wanna keep the RPM high most of the time. Also can be use to descent steep hills as the engine braking is stronger in S mode.

SAT is rarely useful so most of the time just leave it alone. The only time I find it useful is when I wanna quickly attain a higher RPM to overtake: switch on SAT and press harder on the throttle to induce a downshift, after overtaking switch it off.

Anyone can help?

That day high rev my Preve CVT , for the first time I wind down my windows while high revving, and straight away smell something like burning smell. Shocked me

Anyone experience before? I worry it's clutch slip.. But so far few days already when I lift my foot off the brake, the clutch still engaging because car still will move forward without pressing throttle..

But I check some comments on Google they say may be the catalytic converter heating up? car is already 12,000km+
*
I won't worry about it, some cars memang will have burnt smell when driven hard, because your exhaust is running very hot and there is fuel mixed in the exhaust due to rich air-fuel mixture during high RPM.

You're lucky if you can only smell it when you open the window, some cars can smell it even inside the car with all windows closed.

Between vt3 and vt3+,except can withstand higher torque, i think also less whinning sound,rite?
*
VT3 and VT3+ has the same torque tolerance. The difference being some different gears used which reduced whining and different mounting. Someone mentioned VT3+ has better soundproofing, I'm not sure.

VT2 has lower torque tolerance and is used on Saga FLX CVT and Preve exec CVT. It has not undergone any improvement exercise like VT3 did (which became VT3+)

but exhaust i thought only exit through the back... so if moving forward it shouldnt enter the car to prevent fume poisoning??

yesterday and today i just tested again in S mode..
If aircond OFF , windows up, i rev however also no smell ..
If aircond ON, windows up, i rev higher than 3000rpm , after awhile can start smelling the burn smell already. If i stop revving, or change back to D and drive normal , the smell goes off in only few seconds ... so strange !

do i still need to be worried bro?
*
The smell is leaking from the seams at the extractor or catcon or whichever part of the exhaust in the engine that has seams, and enters the cabin through whatever tiny holes or seams in the firewall.

Again, if it only happens when hard revving, I won't worry much. If it happens all the time even during normal driving, then there is a problem.

How old is your car?

guys...i heard that the Preve Executive model failed to go Tian Hou Temple is it true?

QUOTE(:3mushy:3 @ Jun 19 2014, 03:54 PM)
Might be true in the sense referring to that particular case, but the real factor may only be known by the complainant. I've seen Exec Auto going up Genting and Bukit Tinggi, Janda Baik just like any other car without problem laugh.gif
*
The complainant was stuck in a jam on the slope. The car failed to launch from a standstill after stopping halfway on the slope, and rolled backwards instead.

My uneducated guess is: due to the slope, weight of the car (5 person inside the car) and underpowered engine caused severe clutch slippage, the clutch overheats, the TCU disengaged the clutch to protect the drivetrain.

The complainant also noted that after the rear passengers got out the car, he manage to ascend the slope (although the passengers had to walk up). So the main factor is that the engine could not cope with the load.

If he ascended the slope without stopping halfway, I believe this would not happen.

HID would blind the opposite drivers if using normal reflectors and adjusted too high.. as we are using the projector for the HID, should not be a problem..just that, dont adjust too high..
*
Normal projectors made for halogens (eg. the ones on Preve, Myvi) are not suitable for HIDs.

Not to mention, retrofit HIDs are illegal.

I see. Thanks.

Is this new or already common in foreign cars?

To me, it makes the steering wheel "ugly". Still prefer the normal steering wheel.

Thanks.

I think I may have used the wrong word. Instead of shaky, maybe "vibration" is better. Due to engine and/or suspension? After Preve, i tried Suprimo, it was better but still more "vibration" than my expectation. The car sales man said that demo Preve is 2 yrs old and it has done a lot of trips to the country side for sales demo. Bad demo to use for customers as I have told him.

*
I know exactly what you mean. One thing to bear in mind is that the new ANCAP Preve (since end of 2013) have had improved engine mounts, same as the Suprima, from the older Preves, so the vibrations should have reduced. Last time PREVOC used to have a minor engine mounting mod that reduces vibration and engine movement, though I am not sure it completely addresses the issue allenultra

Surprisingly, there is another Jap car I drove that has the same vibration during acceleration, can even feel it on the seat.....the new Honda Accord laugh.gif

the reason i asked is because i just changed mine to 17inch rims.

if before i can get around 50km for bar, now can only get around 40-45.

or is it also depends on the type of tyre you're using?

What is the new size of your tires?
