Gently, gently catchee monkee - MG5 efficiency with light foot

[Tommy]

If you hate efficiency look away now ...
Forgot to charge overnight so when it came to my 45 mile drive to work this morning I was super careful to drive as efficiently as possible, in order to make it there with as much charge as possible.
Started with 31% battery, outside temp 7°C, got to work with 15% battery, 4.7m/KWh
Drove the whole way with the 'powerometer' in the 'efficiency' band, but still kept it at 50-60 mph on dual carriageway and motorway.
Only took me about 5 minutes longer than normal as well.
Love this car

How are you getting home or is it down hill?

Charge at work, but it's not free, so wanted to get here with as much as possible to save a few bob.

Wow, so using 16% of battery you did 45 miles -- leading to a potential 281 miles on a full charge, in the winter! You really were driving miss daisy, right?

Yep, drove it like I was carrying a trifle on my way to granny's house on Christmas Day ... I think the problem is if the power is there you will always use it. I really had to tell myself not to floor it, oh and I didn't use the heater, or ACC ...

I totally rinsed 22% doing 35 miles burning my arse off (literally, damn heated seats are too good in suit trousers), charging at work is free, so no bad consequences beyond poor habit forming.

Heated seats are bad for piles didn't you know. The heat makes the blood vessels dilate

I used 21% doing 35 miles yesterday, mixed urban and A roads, temp 6 degrees, heater on all the way. Showed as 3.3m/kWh but that doesn't make sense.

Ah, free charging at work - that's the dream

Free work charging would be nice. But then again I work from home ha ha.

12,300 miles since March, maybe done 8-9 hours charging at home ?. And it's all from surplus solar, so really is the dream.

Our May 2022 LR was averaging 4.1m/kw in 15C+, 4.1m/kw 10C+ and now sub zero to 5C 3.1m/kw.
This is ALWAYS eco and 3 brake re-gen.
However for the first 6 weeks we were getting 4.5m/kw part of the reason is the tyres had been filled to 2.6 bar not 2.2 bar by Richmond MG Portsmouth
The car is driven 95% single driver with minimal load.
It was notable with this tyre pressure even in efficient mode the tyres " spun" pulling away.
The supplied tyres seem very supple and help give a smooth ride and in our hands an OK drive

Wait so you’re saying that overinflating the tyres can dramatically improve fuel economy??

Yes it can and does.

Try pushing a wheelchair with flat tyres and see how easy it is then blow them up.

A massive difference.

Yes by reducing the rolling reistance it can " improve", at detriment to tyre life and road grip

Spot on.
You don't get something for nothing!
