then why not 2? even lighter...

Bezza got  3 cylinder and  4 cylinder mist people feel 4 cylinder better

Different technologies. Perodua 3 cylinders is no match compare with conti technology.

Toyota also heading 3 cylinders with their Yaris GR, and almera also 3 cylinders.

the whole 5 paragraph, not 1 word mention about "reliability" 

and this "engineer" and doctor wouldn't understand WTF is no replacement for displacement

Charging and storing of electricity are still a huge drawbacks of EV.

I don’t think our government is ready to install charging stations nationwide yet. Even fast charger also need to take more than 15minutes, as compared to refuelling car easily under 5minutes. Also, how will the tariff be since our electric bills are not exactly cheap either.

Unless you’re living in landed and driving mostly in city urban areas, EV is still not quite practical yet.

Perodua 3 cylinder engine is from toyota / daihatsu

which is why the 10 years gap. remember how android phones was 10 years ago? compared to it's norm today?

china nowadays already produce electric cars with very close competition to tesla.
soon, Geely will mass produce them too & be exported to our country.
japanis cars still playing catch up.. toyota going the hydrogen route..

the infras will eventually come when petrol stations are losing customer to electic cars.
petrol stations will have to be phased out / revolutionized to be electic car charger too.

Dude is from volvo, trusted that he know more about reliability and engine than you

perodua....i mean toyota has a lot of 3 pot engine...they had it for a long time already
but it's for japan domestic use only
the reason they don't release it for foreign use is also because that's not how it is being used

dude from volvo but i'm pretty sure he don't even drive 1
i for 1 drive a modern 3 pot car for 9 years now
i know how reliable they can be(over a course of time)

if u learn from these new age modern car(starting 2010)...you'll found out these "engineer" know nuts about anything/car
they just keep putting electronics into it

Typical toyota mindset... old tech = reliable = good

Dude is from volvo, trusted that he know more about reliability and engine than you

I believe he know lot more about car then you, else you can apply to volvo for his job

As outlined in the article 3 pot engine can match the performance of 4 pot engine. Problem is the vibration as it is not even. The complex damping mechanism outlined will give problem if not maintained properly due to wear and tear.

Ev car is definite for  the future, problem is to store electricity is still problematic and have yet to match the cost of storing fossil fuels (for similar capacity).

In fact if human can figure out how to store electricity and water efficiently (as how fossil fuel is stored) then many of world problem now is solved.

Geely-Volvo’s CEVT engine boss explains why the Proton X50’s 3-cylinder is better than a 4-cylinder

[attachmentid=10685433]

[attachmentid=10685435]

...Removing one cylinder is also a super effective in cutting down weight, which is directly related to fuel consumption and exhaust emissions. There’s also the added benefit of achieving better front:rear weight balance in front-wheel drive cars, which is the norm these days anyway.

The benefits of a 3-cylinder over a 4 is very clear. The challenge is to mitigate the vibration problems from a 3-cylinder’s uneven firing order. Solving it is complex, but not difficult if you know what you are doing. Technology for dampers and today’s understanding of engine harmonics is good enough to allow car companies to overcome the problem.

The Geely 1.5TD engine, which Malaysians know as the 1.5 TGDi (identical to 1.5 MPI except for fuel system), contains many of such countermeasures into its engine design.

Explaining them requires a Ph.D but Sandquist briefly said the use of counterweighted crankshafts, dual mass flywheel with centrifugal pendulum absorber damper, single balancing shaft, low noise timing belt, high stiffness oil pan, asymmetric oil pump impeller, engine compartment and vibration dampener – all hidden away from view, allows the 3-cylinder to run very smoothly.

Dr Sandquist adds that vibration (lack of) of the 1.5TD engine is not only controlled, but it’s actually better than some of their rivals’ 4-cylinder engines...

electric will make all these x50/x70 obsolete..

eletric car norm is coming in next 10 years.
