Thanks for sharing ^^

Anyone here just gotten their loans this year?
Mind to share bank and rate?

If you didn't pay for anything, then is free package la....

If free package and they still give you the remaining bottle of new oil, very good leh...

When using I-Stop start, the engine starter has to work harder and faster to restart the engine in order to resuming commuting. Imagine the embarrassment when your car needs a few seconds to restart at the traffic light.

The slightly harsher jerking is normal.

shouldn't it be the opposite? by right the engine should start with the combustion in one of the cylinder then the starter is just give a slight boost to make the startup faster to reduce the wear and stress on starter motor

That method is patented under Suzuki, so i believe Mazda have to make do with the starter method. The starter motor is heavy duty type, not the normal type, definitely can handle much more stress of repeated start cycles. The wear will be more focused on the engine internals, whereby the lubrication is paused the moment the engine stops running.

So far, cars with start/stop system is rather recent and there aren't many engine tear downs to really study the wear levels on such engine internals. But if my memory serves me right, i did read an article many months ago regarding a toyota prius in UK running for almost 700k miles (that's 1.12million km), the car is still running fine. Even the battery also doing ok. With the modern advances in material sciences and engineering, the materials simulation should hold for at least the car model lifecycle, meaning about 7/8 years till the next replacement model comes.
Another factor which contributes to the jerkiness is the gear engaging the moment the engine started. So now you have the initial jerking from the engine start and immediately after that, the transmission gear engagement. If you ever driven a manual transmission car before (or still remember the days of driving school), it is almost like shifting your gear to 1 and starting the engine. The result, the car lurches forward quite violently.

Just that the stop/start mechanism is more refined with electronic controls and timing, so not as harsh as the manual transmission example. Remember, the system has to do 2 things in less than 1 second, restart the engine and engage the transmission gear.
The starter is definitely involved. Smooth or jerkiness is depending on the cylinder position, sometimes it is optimum, sometimes it is not.

I do however agree that with the current start/stop system where it turns off everything other than the electronics and ICE, our climate is just too warm for the air conditioning to be off. Hopefully, more models in the future will come with electric air conditioning compressor rather than the current belt driven type. But then, this will require even stronger power reserve requirements, meaning even more power denser batteries required....

Dear all M3 users, how much is the fuel consumption of 2.0l Skyactiv engine?
