How Driving Mode Affects The mpg.

[dStan]

Ok so I've checked the service manual we have linked in other thread, and for sure it doesn't mention anything about alternator, so I'd assume there is none in MG3. But also, unfortunately, it doesn't mention anything about how 12V battery is charged, or how petrol engine is started

I've just had a good look under the bonnet, and I can't see any sign of an alternator, if there's one there, it must be smaller than the average alternator, and very well hidden.

I've had a little peek under the bonnet and all I can see is what appears to be one of those integrated, starter motors/alternators. Kinda like, when an alternator and a starter motor starting dating and one thing led to another. This is to the front of the engine near the middle.

ISG - integrated starter generator: "The ISG is installed between the engine and gearbox, linked directly to the crankshaft. ISG replaces both the starter motor and the alternator. In addition, ISG supplies power in certain operating conditions, thereby saving fuel, as not all the power is supplied by the engine alone."

That 0-60 time of 6.8 seconds is impressive.

So is the MPG, test average 48.2 compared to combined 64.2 claimed by MG.

I suppose if you include a 27mpg track session in the overall figure, it's bound to drag your average well down.

Yes suppose if they are hammering it. Would be interesting to read what conditions were, will have a rake see if can find autotrader review. Never really checked my overall mpg since I got it just know filling up less frequent and not as much cost as my ill fated MG HS so that's OK.

Same here. But does it make a difference?

The difference is that in the absence of an alternator, it is an important mechanical part that is unlikely to fail.

I suppose you've heard of this website where users upload their consumption over a long period?

That is actually my own profile on Spritmonitor

Unpaid advertising ???

Have you noticed any difference in fuel consumption when using SP95, E10 or SP98?

 

[Deleted member 19052]

My dealer told me to use SP95 E10 mainly for daily driving, and sometimes for long highway trips you can use SP98.

It's obvious that the engineers at MG (like the others) put the health of the combustion engine first.
So when you start up, EVERYTHING is organised to ensure that the combustion engine reaches its ideal operating level without damaging it. You can check on the engine temperature gauge on the dashboard that EV mode will not be triggered BEFORE the target temperature is reached.
In these conditions, the outside temperature has a direct influence on the start-up of EV operation.

This is not specific to MG and all full hybrid cars operate in this way.

Ours runs in Eco regen 2 EV at the start of any journey, the engine does NOT cut in at all for a mile or two.

Some is downhill and it can be in HEV or EV.

Why does regen give a minus figure on the dash? it should be a plus as you are putting amps into the EV battery, using EV should be a minus.

My Honda garage advised me to use E10 then SP95 then SP98 alternately for the Jazz hybrid.

In use, the SP98 gave better acceleration and slightly lower fuel consumption.

The negative figures for EV can be explained as follows:

You have to look at things from the point of view of CONSUMPTION.

6W means that you consume 6W of your HT battery.

- 3 W means that your consumption is negative and therefore NIL and that in addition the 3 W will directly supply your HT battery - this is the principle of regeneration.

Very interesting Copilux ?
