New MG ZS high fuel consumption and frosty glass shattering

You calculate MPG from miles done & amount of fuel put in. Price does not come into it.

Stop looking at the average MPG on the dash & run tank to tank checks. But need several to get any sort of average.

"You calculate MPG from miles done & amount of fuel put in. Price does not come into it".

I calculate it correctly, amount of mpg from the amount of gallons put in for the money paid.

"Stop looking at the average MPG on the dash & run tank to tank checks. But need several to get any sort of average".

I've been calculating tank to tank since i've had it, that's over 15 months now. The remaining miles goes off at below 30 miles, every time that's happened i've put fuel in, then calculated how many miles I get before the remaining miles goes off again. For 15 months.

Clearly, the OP does incredibly slow journeys with massive amounts of engine idle time, I don't think any car would get much better economy.

Nope, I do shorter journeys and never leave my car on idle unless it's in the morning for maybe a few mins before driving off.

I think we already know precisely why MPG is so poor, despite what you say, your average speed of 9-10 mph is the issue, cycling speed.

Why would you need to do a few mins of idle before driving off? That is the exception for me, a few winter days when I wait for the heated front screen to clear some frost or ice, literally 1-3 mins but other than that set off immediately after starting.

If you are still dissatisfied you need to change your car at this point. I have a 2014 2.0 turbo diesel with 163PS that averages 43.9 mpg long term - it is bigger and heavier than your car (7 seater), I drive briskly and live in a big city and often queue in "rush hour" traffic. Manufacturer tests say 43.5 urban so I can't really complain.

If I've got the right model, your car is 35 mpg urban and your dealer got 33mpg so looks about right. I only ever pay attention to the lowest of the official MPG figure as this is nearest to the real world, the others are optimal conditions. The discrepancy is down to the way you use the car.

Coming back to this as the fuel consumption was recently checked by the dealer, they emailed several pictures showing 32/33mpg in the current mileage screen, I asked them for the accumulated mileage screen as they drove it local for a week but they didn't send this. As I was having issues with the central screen and dashboard screen also, they reset the software.

I've had it back a week and the mileage has gone up by a few mpg, i.e. to approx 22mpg from 19mpg but this may not stay the same. Since i've had it for nearly 15 months, it's never got to 20mpg local.

I don't know how they got 33mpg but i don't think it was all local from the distance and time taken.

As others have said, it sounds like it's the way you drive and not the car. I think the MPG achieved when your dealer had the car proves this. Though it's still terrible MPG for a 1ltr.

I have Toyota Corolla 1.8 hybrid and currently getting around 60mpg. This will increase to 70+mpg when the weather is warmer. I do mostly short journeys.

I looked at the MG ZS before i decided on my current car and so glad i didn't go for it.

I don't think I drive any more aggressively than the dealer would have done, i've had it back over a week and am still getting almost the same mileage give or take a mile. I drive sedately and don't speed or anything. I've no idea how they got 33mpg, even on 40/50mph it'll give around 26mpg. I asked them to drive it local on town roads.

Poppy, good thing you didn't buy the MG ZS, it'll never reach anywhere near the toyota hybrid mpg.

Anyway, i need to change it that's a given. I would've preferred to return it to the dealer, i've been telling them about the poor mpg from week 2 of owing it and, like I said, they initially said drive it 500 to let engine 'bed in' then they said drive it 2,500 miles. I did 4,000 miles in the year so 2,500 took me 8 months.

So where are you getting 26 mpg @ 40/50 mph from? Unless you can drive a full tank of fuel at that speed.

I meant when i drive 40/50mph the mileage shows around 26mpg for that time, even 10 mins is enough to show that, overall it goes up and down and accumulated (trip computer) always shows 18/19mpg from refill to empty. On motorway driving it will show around 33mpg.

That is truly pants for a 1 ltr...when I was looking and test driving similar 1ltr cars, (eg T-Roc, Vitara), I was seeing an easy 40/50 mpg figure . I would be looking to sell and get something more economical?

That's what i'm doing. Was going to sell it in November 2022 then a few weeks later the window shattered, couldn't get one from the dealer for some weeks.

Ideally I was wanting to return it to the dealer/finance company but they're not interested. I was told the engine is enough for the car and they wasted 8 months making me drive it to at least 2,500 miles. The issue was raised with them within the first month and technically they've had the car 3 times to look at excessive fuel consumption. They say nothing wrong with it.

The dealer's offer is the lowest at the moment, they're sticking to what they offered in first week of December 2022 when prices dropped, since January prices have risen. Even webuyanycar are offering more than the dealer and £1,000 more than their December 2022 price. Carwow and motorway are higher prices but they're an auction in a way so no way of guaranteeing their guide prices. Dealers are free to offer what they want. Cazoo was higher than all others previously but now same as webuyanycar.

If you're only doing 4000 miles a year, then does a lot fuel economy matter that much in the grand scheme of things?

33mpg @ £1.60/l gives you about 22p/mile or £880/year.
22mpg @ £1.60/l gives you about 33p/mile or £1320/year.

So you're paying about £440/year more in fuel, but how much will you have lost in depreciation already?

I can understand if you want rid of the car anyway, but I don't think it makes sense to do it based on fuel economy alone especially since a large part of the problem is your driving patterns; the 9mph average speed over presumably short journeys, which is going to be horrendous in any car. My 1.5 diesel will do over 60mpg on a long slow run, but easily low 20's on the local journeys.

Indeed, it is surprising how big a difference you need in fuel consumption to make it worth changing the car with all the attendant costs.
If you are really concerned about fuel costs most sensible thing to do is to look at not using the car for some of those journeys. In your position I would be tempted to get rid of the car, buy a cargo e-bike and/or some individual bikes and put aside a budget for taxis or by the hour (Zipcar et cetera) hire cars.
