but my SV got knocking sound when left corner, not right corner

NASA grade aluminium. It's a super car after all.

Bigger and wider car of course more heavier

But not exactly, did you know satria neo heavier than alza?

Because the Macampro IAFM 1.6L engine is casted using a stone furnace due to the lack of proper facilities as there aren't enough R&D funds (that's why proton asked for 3billion recently), therefore the end result is that the weight of the engine is very heavy. Without it the Persona is actually as light as a kancil  .

Donno why. Just recently comparing car spec, surprisingly alza kerb weight are lighter than neo.

Yup, it's untrue.

Why is the Vios lighter? I don't know. But even after debunking my claims on how heavy the campro is, and after removing the campro engine the car will still probably be heavier/slightly heavier than a Vios unless the engine's weight is more than 200KG. Even so, if you remove the engine in a Vios, it'll probably still be lighter than a Persona without an engine. So eliminating that factor, it probably can be assumed that the panels are thicker, body is heavier due to thicker /heavier material and et cetera. I don't think soundproofing would be a significant factor here since the Persona's soundproofing probably isn't too heavy to begin with anyway.

. You mean Skyactiv body? If a car's weight can change on the fly (aside from losing things or down/up force) that would be very interesting .

1. Find an SA
2. Go to showroom, meet up, ask for discounts and promo
3. Everything ok, pay partial/full downpayment
4. Give 3 months payslip and photocopy IC
5. Bank will contact you and do verification
6. Few days later, bank will call saying loan approved/not
7. SA will call to notify you on your allocation and tentative delivery date
8. Choose a number plate
9. SA will give you your loan docs to sign, pay remaining downpayment if not, give 2nd driver for insurance if needed
10. Wait for car

good for properly breaking in the engine.

the right term is "varying"

keep your rpm at different point at different interval. combination of slow driving, cruse driving, fast driving and moronic driving.

1K service is very important.
