good try but not good enough if compared german engine, if can exert >150hp then i think is very good liao

140hp ?

cvt lancer 155hp oso not enough near c200k

The emphasis on the development of CFE focuses more on torque rather than horsepower.

when malaysia release RON 88?

even torque also not that high le

btw can we tune for more power? does it affect d durability of this engine? i see BMW/Merc/VW all got special tuning kit to boost more powarrr duno proton has it anot.

An
electrical pump which is actuated
on key-off to provide coolant to the
turbocharger bearing housing after
engine shutdown. This pump also
circulates coolant around the rest of
the coolant circuit to prevent boiling,
an important feature in the high
ambient temperature of Malaysia
and Proton’s export markets.

Merc manage to extract 270Nm of torque from it's 1.8 litre 4 cylinder engine though.

More expensive to maintain as well?

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

Add direct injection and it will be like ford ecoboost

Turbocharging is getting more common though...

VW, BMW, PSA, Ford 

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..

I would like to hear comments from Exora owners, for CFE real life reliability 

- Engine volume is 1,561 cc instead of 1,597 cc on standard Campro due to reduced stroke, but retained bore
- Different bore and stroke

What the hell,the first one retained bore the second one different bore?how is it possible? variable bore technology?hahaha

french car european like this kot ..............

my savvy also gt issue especially on all sensors

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

sure can wan....

I would like to hear comments from Exora owners, for CFE real life reliability 

have to wait for their 30k, 50k 80k field report  feedback kua.. 

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.

french car

it's funny cos their older NA engine quite reliable (with lower power) maybe just glitchy electronics and sked overheat... 

that you called quite reliable?

it still take you back home mah..    nowadays some car terus shutdown at roadside how?

overheat and eletric glitch can still drive?

you  sure bo

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...

how about cfe+hybrid.. 

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.

stilll got but maybe used for their version of proton emas.. our proton emas dunno yet will use which engine..
if family Y is not ready then theyll source mitsu? engine agen?

Hybrid Campro engine

In March 2007, PROTON and Lotus have announced their concept model of a Proton Gen•2 powered by a hybrid powerplant that uses the CamPro engine. The concept model was revealed during the 2007 Geneva Motor Show from 8 ~ 18 March 2007.[7]

The hybrid power-plant system, which is known as EVE system (Efficient, Viable, Environmental) will be using the same S4PH engine as the one that powers the present gasoline version of the Gen•2, combined together with a 30 kW, 144V electric motor. The main purpose of the hybrid powerplant system is to provide a hybrid system that can be retrofitted to existing models, retaining the same power-plant and also eliminating the need to develop a completely different platform, like the Honda Civic Hybrid. Unlike the IMA (Integrated Motor Assist) technology in the Civic Hybrid that uses a bulky Ni-MH battery pack, the EVE Hybrid system will use a Li-ion battery pack inside the engine bay.

The EVE Hybrid System will have 3 key technologies:

    "Micro-hybrid" start-stop system - An integrated starter-alternator system is installed to switch off the engine automatically when the engine stops, for example at a traffic light. The engine will automatically restart when the gas pedal is depressed.
    Full parallel hybrid technology - Combines the existing S4PH engine with a 30 kW, 144V electric motor, resulting in higher power (141 bhp combined), higher torque (233 N-m combined), lower emission (up to 22% carbon dioxide reduction) and better fuel economy (up to 4.6 L/100 km). The system also includes regenerative braking system.
    Continuously Variable Transmission (CVT) - The CVT system provides an infinite number of gear ratios for better efficiency.

The combined power and torque for the power-plant system are as follows:

    Max power (gasoline engine only): 110 bhp (82 kW; 112 PS) @ 6,000rpm
    Max torque (gasoline engine only): 148 N·m (109 ft·lbf) @ 4,000rpm
    Max power (combined): 141 bhp (105 kW; 143 PS) @ 5,500rpm
    Max torque (combined): 233 N·m (172 ft·lbf) @ 1,500rpm (limited to 180 Nm continuous)

Merc manage to extract 270Nm of torque from it's 1.8 litre 4 cylinder engine though.

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.

But the initial acceleration too sluggish liao. Even after remap everything on preve. They should do something about the initial acceleration. Maybe install another scroll in the engine.

Not sure about Preve, some said the one install on Exora is tuned more aggressive because of weight 1.5tan. I'm currently owner of exora CFE, no problem accelerate from 0 to 100 in 10 second. Preve should do better.

3 weeks ago, I asked the foreman to tune it to exora one.got slightly better but still sluggish. Below 2000rpm,even Kia picanto feels more responsive than preve. In high speed,preve is unbeatable by most similar priced car but in traffic jam and crawling situation 

i think is the CVT ratio problem instead on engine

I just own a proton saga FLX SE recently compare with old avanza which i still drive i can fee the saga pick up which late respond compare regular AT. I can feel it need abt 1 or 2 second only can change  to ratio that match ur engine output if u maintain ur pedal with out press deeper.

I can feel the power but it like late coming only >< i guess there still need improve in tuning the CVT to math Malaysian drivestyle more

Seems legit maybe its the cvt. yours is 1.6 or 1.3?

SE is 1.6

How is the fuel consumption? My sis in law want to buy one but I asked her to go for almera or myvi extreme.

Maybe causes by safety feature on CVT3 GB. As inform by kristof (cvt supplier for proton) the clutch will half open for smooth acceleration from static and also to prevent engine die on low rpm until certain speed before clutch fully closed. You can refer here for CVT3 GB.

What is your fuel consumption for your car?

Mine is exora BOLD CFE currently 11-12L/100km. Still 3000KM.

SE is 1.6 but also might be their purpose to doing so also cause i heard Honda give up CVT on city because malaysian driver attitude on slam and drive which kill the CVT faster than  expected

Mine is 12L/km twice the amount they claimed on the brochure. 6.6L/100km my bontut. Currently is about 7000km liao.

nice, bump year old threads

That was very high for preve which weight around 1.3 tan compare with exora which 1.5 tan. What modification had you done? racing chip or only ECU remap?

No modification,only the remap in the service center. Do you know the normal fuel consumption for preve?

city driving a lot?

Only city driving,never go out of town by this car.

juz wanna ask. my fren got a new preve. keep puji. say naik genting win camry 2.4 ... smoke him kaw kaw.

then someone told me more comfort than bmw 320d.

ada betul ka?

than u will hard to archive 6.6 ><

City drive involve a lot stop and go which will drag FC to the worst

My avanza regular 60 highway 40 city give me 450km per tank but if i go in KL for whole day long >< which make it 50:50 my FC will drop till 380-400 per tank only

If at least 8 or 9L still understandable but this is double the amount it supposed to be liao. Even though preve's fuel consumption is high,my sis Kia picanto is higher. Preve rm50 can last for 7-8 days but the Kia can only last for 5 days and some time even less.

if u r 100% city drive definitely nothing strange to double up cause jamming also comsume Fuel too leh.... BTW also depend on driving attitude too la.. some ppl heavy foot one (like my boss my avanza if he drive sure can't archive 400km even highway lol

then why choose such low rated torque gearbox to mate to a turbo engine? sounds like asking for trouble in long run..
