The Ultimate MG5 "Real World" Energy Consumption Thread

[Alb]

at 50 mph I get around 4.5 kw/m

That would be a miracle!
4.5 Miles/kWh on the other hand .........

 

[Dino]

So my best month so far, still trying to lighten my right foot.
High was 4.7 and low was 2.9 for individual trips.
Mostly in Normal mode with air con on and KERS 1/2 on open road and 3 for the school/shopping trips

 

[Rocinante]

Ah yes. This seems about right. I tend to drive "very relaxed" on motorways at about 60. This seems to be a reasonable compromise on getting there in a reasonable time and getting good consumption. I never go anywhere in a hurry. I do though keep a lookout for lorries creeping up on me and then get out of their way!

How are you getting out of the way of HGV's ?

I might be misreading the situation, but it sounds like you are hogging the middle lane if you are able to move over to allow HGVs to pass ?

If there is room for you to move over for HGVs, then there is room for you to be in the inside lane and move back out as necessary. You do realise it is an offence to sit in the middle lane if you are able to move over, punishable by a £100 fine and 3 points.

Apologies if I'm misreading the situation and for derailing the topic, but if he had said he regularly ran red lights, I think someone would comment, which is awarded the same punishment.

If you're doing 60 then they shouldn't catch you up.

? You made a lot of assumptions there based on one small statement! Perhaps he meant if a lorry catches him up he will slow down for them to overtake?

Lots of foreign lorries and sometimes the Irish lorries overtake me when I'm doing 60, especially down some of the bigger hills. I tend to slow down so they can clear the middle lane as quickly as possible and then I increase (it only takes a few movements of the stalk to achieve this).

I did say "I might be misreading the situation", so I recognise the situation isn't clear, but he says "get out of their way", not "slow down".

Birmingham to Dover this morning. Light traffic and. Steady 60mph. Topped up at Maidstone.

 

[CuriousIslander]

Oh dear - what have I started????
Just to clear things up..
No I don't hog the middle lane...
No I don't get in the way of lorries ... If they are approaching from behind, when they get to within a hundred yards or so I speed up and pull away. In that way I "get out of their way"........ I am quite happy to overtake slower vehicles, but generally find that traveling at 60ish is a good compromise between getting to where I am going with no stress and in a reasonable time with reasonable battery consumption.
HTH
Incidentally, with the current good weather this relaxed way of driving is earning me 4.7 miles per kwh overall since April 1st.

4.5 Miles/kWh on the other hand .........

Oops. I’m knew to kw’s and miles. Used to litres and kilometres

 

[Fluffykins]

Just got back from a 500 mile round trip 5o the Lake District plus plenty of touring miles up there.
The final leg of the run home was 120 miles. We started with the GOM estimating 39 miles would be left in the battery when we got home (excellent weather. E mode and KERS 3).
In actuality we had at least 52 miles left on arrival, probably more.

 

[ArfurM]

Bit late to the party, but this was my Jun summary for my Standard Range:

Just for context we drive in normal mode/KERS2 and live in rural Wales, so LOTS of up and down (I live on a 1:5 hill, altho' the top is !:4!). Don't use the A/C much TBH....

 

[amackayj]

Just done a 600 mile round trip up the M1, A1, A19 and back.
Way up was very hot, so had the AC running. Got into a spot of bother thanks to Zapmap sending me on a massive detour to find chargers (this was my first long trip in a full EV). So ended up doing 70+ for the last 100 miles and boy did it hit my mi/kWh! A steady 4.0 quickly dropped to 3.7 and never really recovered. It was also quite windy, which would not have helped.

I suspect that the indicated mi/kWh value is similar to the estimated range i.e. an estimate rather than an absolute value.

Moral of the story: don't expect good efficiency if you are going to be doing motorway speeds.

Ok so I have been monitoring this thread from the start, and i decided I would do a little test with my MG5 SR.
For the past few months now, I have been doing the same journey every few weeks to take my wife, this is for medical treatment on a foot injury so she as been going to a Specialised podiatry clinic in Leyland, it’s around a 14 mile trip from home, with varying speed limits of between 20-50 MPH, and is mainly trough built up areas, and with varying traffic conditions.

So there as been many times on this forum and others, that questions and options on what is the best mode to use and the best regeneration setting, I normally drive in Eco1 and my left hand is used to change the Regen levels when I can see I am going to be slowing down or stopping, to get as much Regen as possible, I will switch from Regen 1 to 2/3 and back to 1 again as I move off.
So for this test I left the settings the same and never change anything for the whole of the journeys, no heating or Air-conditioning was ever used at first and this is what I found, I started the test using E3= economy mode with the highest regen setting.

Then same journey a few weeks later car in Eco 2

Again same journey this time car in Eco 1

As you can see not much difference in any of the settings, when in Eco mode, yes there is some small variations in temperature but nothing else, and trough out my testing I did my level best to drive in the same manor and keeping to the speed limits every time.

So next I decide to leave the car in its default mode of N 2= Normal with Regen set in level 2,

So this was better than Eco mode only a small amount but better, and to double check this was right I did the same again today and again better than the Eco mode, plus today the whole of the Journey was driven with the Air-conditioning on full for the whole of the journey.

So coming home today, I made a small detour to a garden centre for some large bags of compost which where quite a weight, and a short stop off for a pub lunch Air-conditioning still full on and got this result,

So I think I will from now on leave the car in the default mode, as there as to be a reason why, that’s how the car was set to operate when it came from the factory, and not to default into Eco mode, plus we know the car is far more responsive in the feeling of the steering and it’s acceleration response. Plus the fingers on my left hand will no long be heading for a repetitive strain injury perhaps.

Les, one thing I do notice from all those photos is that the lower the average speed, the higher the m/kWh.
16=4.9
19=4.7 (N2)
19=4.3 (E3)
20=4.4
23-4.2

 

[Deep purple]

From my interpretation of what the dashboard displays say the KER systems in the MG5 will vary the amount of regeneration when the throttle is released, as we all know well.
But what I suspect not everyone has noticed is that if you are in KERS 1 and release the throttle then GENTLY depress the brake pedal this increases the regen applied (without using the brakes themselves) until max regen is reached. Only then do the brakes start to be applied.
So KERS number only really determines whether you have to move your foot from accelerator to brake very often.
A very good Youtube on EV efficiency makes an argument that strong regeneration wastes energy as it incurs losses (20%?) in the process. So the best strategy is to use KERS1 and release the throttle well ahead on any obstruction rather than leave it until later and either invoke KERS3 or use the brake pedal which will apply full KERS and then brakes if needed.

 

[Jomarkh]

I think that the temperature has more effect on the M/kWh.
Take a look 9*c 4.2m/kWh in the morning then 20*c 4.9m/kWh late afternoon....

Hiya Gomev, your right, I had seen this myself, but over a very short distance about 14 miles, the MPH I wouldn’t have thought would have much effect and as I said, I did try to drive the same way on each run depending on traffic, we all no if you drive more gentle or slower, you will get better range out of any vehicle but the difference over such a short trip is minimal a longer and faster journey it would be different this I know.

Now Jomarkh, #76 has commented above about the temperature this is another valid point as well which does have an effect

Said, quote, So the best strategy is to use KERS1 and release the throttle well ahead on any obstruction rather than leave it until later and either invoke KERS3 or use the brake pedal which will apply full KERS and then brakes if needed.
Unquote,

This is the right way to drive any vehicle EV or not and something I have always done it’s called anticipating the road ahead, and it works that’s is for sure.

Anyhow I was trying to show that on short journeys I think the default mode as been set up quite well by MG in my opinion. But many thanks for the input by everyone.

Les, found this very informative.
I do runs the Heathrow every day and like you have tried out every setting there is to try. Without a doubt though the temperature is very high on the the list that affects your miles / kw.
Early mornings (3am to 7am) I get 3.8 to 4.1 depending on settings.
Afternoons I get 4.4 to 4.8 depending on settings.
Of course this is through July this year.
So far I think the best I am getting is with Eco on and Kers 3. I have had the AC on full blast most of the time and don’t really notice much difference with it off or on.
This all needs a lot more study and data input, but it’s great that everyone is giving their own input to make that happen.
I am always a careful driver and anticipate what’s ahead of me (30 years NCD) but I am going to try out Kers1 and touching the break. It sounds like it might work.

Avoiding hard acceleration and high speeds, slowing early before a stop and doing as much lift and coast as possible will always give you the best mi/kWh whatever regen or throttle setting you choose.
