More expensive to maintain as well?

murphy's law.. biggrin.gif too many parts.. 1.8 to 2L more simple..and more reliable.

Turbocharging is getting more common though...

VW, BMW, PSA, Ford  hmm.gif

Japanese and Korean manufacturers are not caught up in this though.

common but don't need it, japanese go for reliability minimal downtime..

just go 308 turbo thread ler.. everyday got problem..

heard the AMT think scary right, got some owners lost power during gearshift/acceleration..
if only they put the basic saga1.3 auto into the savvy, even used one at 15k sure got many people sapu.. since it look quite decent, saga hatch..

i see the koreans and japanese focusing towards hybrid on most of their best/projected selling models...

while, the westerns....turbo engines.

and I see hybrid is the future direction....

CFE isn't going to be fuel saving...so, people need to figure that out....don't get the car and lament later that you were hoping for good economy.
*
small turbo engine also got limit, cos at the end of the day energy conservation is more important, you can only get so much out of efficiency to move a car, but we also need to recover kinetic energy from moving vehicle also since already paid with fuel to get it moving, so hybrid is still way forward...

overheat and eletric glitch can still drive?

you  sure bo

overheat as in temp rise.. nearly to red , still can drive wot..

electric glitch, error code come out warning sign, engine still running, if more serious like bad coil (which i kena before on 407) they will put engine to limp home mode, maybe hard to rev over 3k rpm so why cannot drive?

i remember lotus did a range extender engine with 50KW right? to power the pure electric vehicle on gas if needed.. that would be interesting as well.

The emphasis on the development of CFE focuses more on torque rather than horsepower.
*
but only 200Nm wor, and every other manufacturer with a forced induction engine of 1.6-1.8L would be producing 240-260NM of torque..

They need to retain torque below 215nm to preserve CVT3 GB. But if you not sayang your GB you can increase the boost pressure more than 1 bar(Currently 0.6bar=8.70228psi) and remap ECU to release this real CFE performance.
*
then why choose such low rated torque gearbox to mate to a turbo engine? sounds like asking for trouble in long run..

For fuel efficiency. Compare with manual and auto, cvt is better. But durability is unknown.

CVT like xtronic - nissan or toyota 7s CVT is reliable.. cvt from punch who didnt supply to any big int'l manufacturers (from their powerpoint 1-2years ago they say supply to china market mostly),..that is unknown ..

if i can remember correctly, the new unit of preve GB would cost around 17k. and punch powertrain already open their branch in malaysia, specifically in tanjung malim to sell a reconstructive unit for a cheaper price.. Proton and Punch Powertrain is having a long term partnership.. the first cvt gearbox by punch powertrain are being used in the saga flx.. its been 3 years, no major problem in a large scale.. it should be fine, i think... just pray hard lah hahahaha
*
not to say the current cvt is weak but you know la.. AT gearbox where got so tahan like 8-10year or 200-300k without shifting errors wan.. if keep the car long time, then have to keep back up plan also.. biggrin.gif

From what i know, VVT cracking only causes oil leaking from VVT bay which my self also face on 2nd day i received my car. About that car burned up, i not knowing the causes.

i do believe in a prompt maintenance... my uncle is using an old volvo. i was told the car is almost 20yo already. and the GB is one of those early adopters of cvt. and according to him, it was produced by the same manufacturer of preve gb, punch powertrain. the engine and gearbox is still intact.. no major overhauled, no major issues with the gearbox. just a few times leaking, and wear an tear problem. i dont know the exact model of the V. i dont think my uncle told me half truth...

for the owner's sake lets hope it can tahan until so long, since we already know this preve version cannot tahan high torque.. biggrin.gif
