hmmm have alot ot understand bout electric motors
The PCU (Power Control Unit) is the inverter in case of the city. The electric motor itself is just a motor, is the ECU and PCU are the brains that does all the signal receiving, calculation, controls, communications and send signal out to the electric motors, engines, clutch mechanism on what to do and when to do it.

This City don't need a gearbox coz the wheels are driven by electric motor and has no connection with the engine. The engine only has a single ratio 1:1 when it cuts in to help during the high speed mode. Correct me if im wrong. There's only a mechanism to make the connections switch between the wheels and electric motors and engine. Even for this city the Reverse is powered by the electric motor also.
yeah after some research, the immd system is indeed very next gen.

To understand the immd and the no transmission idea, one must not assume it to be a regular hybrid car. it's quite the opposite, at least mostly when driven in the city.

here are my findings, which i hope will make it easy for all to understand

- It is more like an electric car with a petrol engine
- the petrol engine assists the electric drive
- the petrol engine runs in the background until car hit highway speeds
- Motor 1 does the regen like an alternator
- Motor 2 drive the wheels
- The petrol engine runs to either, or at the same time:
- - power motor 1, to charge battery, to power motor 2, to drive the front wheels
- - power motor 1, to charge battery
- - kick in at highway speeds
- there's no transmission because:
- - the car is driven primarily by an electric motor
- - the engine runs at a constant 6th gear metaphorically



Not sure if the upcoming Honda City immd's version matches but I found this video very helpful, it's not on the 1.5L immd specifically but provides a good idea

Yup, honda make it a bit simpler for the mass to understand so that it doesn't sound so confusing to them so they still called the gear mechanism e-cvt. In the ads and the much spoken 253Nm is actually the torque generated by the electric motor and it has a small workable range for low speed. Much like short burst of power to get things moving up to speed a bit quicker.

My question is, what’s the warranty on this? If ANYTHING goes wrong, you’ll have to pay Honda Malaysia prices for this out of warranty.

5 years, ok fine. 8 years would be amazing and a winner. Then there’s the price. If it’s much higher than the current full spec City, I’ll rather use the same amount of money to get the X70. Get more car for the money.

more electrical parts will be costly to fix. I don't think any outside mechanic can fix it... then, this car has to pakai buang like our other home electrical products.

I think in this city case, probably the bearings on the electric motors, the clutch packs for the direct drive switch gear for the switching mechanism, the batteries but since it's a Li battery it will be better than the older batteries used in older hybrid, and the usual engine parts

Let's wait and see how things unfold

Still can repair, but by changing parts as a whole, like whole motor, whole this and that.......haha

I would treat cars with such tech like a premium brand front load washing machine. The motor that turns the drums, belting, body, doors, power cords, soap/detergent loader will definitely last.
What dont last is the control board...and cost a bomb to replace.
Batteries definitely needs to be replaced at certain point and the cost is key.

Remember our younger days playing with battery powered RC cars? One day it just stopped running even when the motor is still fine if we test it and we replaces the battery. We just cant figure out whats wrong and just throw it away.

Still, i would love to own a Tesla if i can afford it.

We gotta start somewhere. As much as I hate to admit it - electric cars are the way of the automotive future unless someone commercializes hydrogen fuel cell or nuclear power.

However having said that I'd do what Ixeo do and let those who can afford it make it commercially viable for the rest of us normal folks. So in the meantime I'll keep buying petrol.

Actually crude oil has so much reserves, still have alot.
"There are 1.65 trillion barrels of proven oil reserves in the world as of 2016. The world has proven reserves equivalent to 46.6 times its annual consumption levels. This means it has about 47 years of oil left (at current consumption levels and excluding unproven reserves). "

Well with Euro clamping down on emissions, vehicle fuel usage will definitely drop. China also realises it cannot allow pollution to fog up Beijing, so the government would also steer it away from dino juice. Shenzhen for example, can only have EV cabs. So all cabs there are EV.

Which means... don't worry about dino juice!

but to produce electricity, you need fossil fuel/coal to burn.
