ktards ain't doing any better here either.
The "vibration damper" mentioned in that article is a specific engine part usually built as part of the crank pulley. It is not related to the engine mount. steady bro, just FYI.
Like I asked, which 3 cylinder engine you know need this part replaced after 5 years? or any other engine internal parts referred to in that article?

You guys keep mentioning engine mount, I already addressed it in my post replying to steady bro.

As for vehicle lifetime, you're just taking that "lifetime fluid" as reference and running with it. If manufacturer deem the car's lifetime to be 5 years, why do some markets enjoy 7-10 yrs warranties on their cars? in fact in Malaysia some Ford cars get 7 years warranty on clutch parts and 10 years for the transmission controller. Why bother with such long warranties if they don't think the car can last that long?

Well you look at the x50 now, only offer 5 years unlimited mileage. What does that tell you?

If its 10 years unlimited mileage warranty on engine and transmission then I will consider.

I am also speaking from experience, was driving Kelisa when I was student so I know what a 3cyl engine feels like. You can say all you want, 3 cyl will definitely vibrate more than 4 cyl because of harmonic imbalance, what car manufacturers can do is implement dampening and counterbalance shaft to negate the vibration. How long this will last time will tell, I certainly wouldnt be touching this from a mile away for the sake of better fuel economy especially from an unproven car manufacturer.

Instead, trust k/tard?

The onus is on those calling him out to prove his statement is wrong though, not using strawman arguments.

Thats akin to how anti-vaccine people work.

You don't know what you are talking about.

Many people wanted more power and turbocharging is a CHEAPER ways to get those extra power. Ever wondered why there are so many turbo charged diesel pickup in Malaysia?

It tells me Malaysian car buyers are being shortchanged everywhere by being given only 5 years warranty with every car sold. Meanwhile in China the very same engine in the Geely Binyue comes with 8 years warranty.

You made a blanket statement that carmakers deem 5 yrs being the lifetime of their cars. I told you that is false. That's the end of it.

My apology.

Yes, there are people who know nothing about turbocharging and talk nonsense. I think with turbocharging, you uses 10% more fuel but get 20+% more power. I don't have the exact figures.

4-stroke 1-cylinder Honda Cub kapchai's do not vibrate like crazy. Maybe you are referring to those 2-stroke noisy and smoky kapchai's, eg Suzuki 110RG Sport.

Number and size of cylinders are optimized for the weight of the vehicle.

Of course have to be blanket statement, different car manufacturers put different lifespan for their cars. European cars have shorter lifespans, again dependent on the specific brand and complexity. Japanese brands tends to last longer.

We'll see how this Proton X50 holds up in 5 years yeah. LOL

Good god the sohai logic being peddled here.....

if 3 cylinder better why not 2 cylinder or 1 cylinder?
because 3-cylinder is the minimum? If manufacturers can make 2 cylinder engines without them vibrating out of the car, they will most definitely do so. In fact the new breed of Ford ecoboost 3-cylinder engine have cylinder deactivation technology, so the engine only runs on 2 cylinders when cruising.

3 cylinder less reliable
Malaysians have been driving 3-cylinder cars for donkey years and praise that brand to be super reliable. Why suddenly now 3-cylinder = unreliable.

Turbo is for expensive cars that owners don't care about fuel economy
Obviously, those small turbo made for economy cars are not the same as big turbos/twinturbos/biturbos/quadturbos you find on luxury cars.

All those additional engine parts to reduce vibration will be expensive to replace
Except for the timing belt, the other parts are not wear and tear parts and are designed to last the lifetime of the engine. Those old 3-cylinder that vibrate like washing machine, how often do you replace the flywheel?

https://auto.howstuffworks.com/turbo.htm
The advantage of compressing the air is that it lets the engine squeeze more air into a cylinder, and more air means that more fuel can be added. Therefore, you get more power from each explosion in each cylinder. A turbocharged engine produces more power overall than the same engine without the charging. ...

Turbochargers allow an engine to burn more fuel and air by packing more into the existing cylinders. ....


Basic science says that turbo chargers in modern post-2010 mass consumer marketed car engines burn more fuel for the normally needed power boost, eg when the driver accelerates from stationary(especially in traffic jams) and cruising at a high speed on the highways. .......

Lol manader. Ayam using one now mileage 110k km, still on stock mounting and everything

Meanwhile the other 4 cyl car at home (poton suprima and pijot 308) mileage baru 105k km already almost needing its 4th engine mounting change

Ayam pesta ekobus fuel consumption around 8-10l/100km, meanwhile the pijot and ploton same driving style and condition around 12-14l/100km

Out of 1000 x50 out there how many will actually reached 500k km in 5 years lol?

For that one or two people, Proton can cover the replacement cost, while the perceived confidence boost that it gives to customers will exponentially increase the x50 sales.

you have to compare apple to apple. Your pesta should be compared with 4 cyl pesta. Comparing with other brands will bring in other quality issues.

4 cyl fiesta 1.5/1.6 actually is even more problematic than the 3 cyl ecoboost ones. They've changed quite a few materials to be stronger on the 1.0 compared to the 1.5/1.6

If your Proton Suprima had its 4th engine mounting change within 10 years, the likely problem is it's Malaysian-invented CamPro engine. .......

Also, for those who say 3-cylinder cannot make big power:

Toyota's latest hothatch the 2020 GR Yaris makes 268hp and 370Nm from a 1.6l turbocharged......3 cylinder engine.

But not a squeak heard from /k's car "experts", maybe because it's toyota so it's OK.
