Any range readout from an EV tends to be referred to as a GoM - a "Guess-o-Meter". It is usually influenced by your recent consumption rate and the battery management system's best guess as to the capacity of your battery. Both of these things are influenced by temperature and consumption is highly influenced by both weather and driving style.

 

I don't have an MG5 but the 250 miles stated range is based on the WLTP test cycle which is unrealistic and will not reflect the actual range you will achieve based on several factors.

My 2019 Model 3 was stated 253 miles WLTP I believe but I've never seen more than 232 miles indicated on a 100% charge from new so a similar situation.

 

Just like ICE cars never get the stated MPG, EV's never* get the stated range.

*Maybe downhill in a vacuum.

 

I also don't have one but have driven one recently. The useable battery is "only" about 57kWh with the remainder being held as buffers. If you are getting 220 miles from that then you are achieving around 3.9 miles/kWh which isn't bad for total usage. To get close to WLTP you need warmer weather and to drive very gently and slowly. If the dash reads 100% then your battery is fully charged.

 

It has a 57 kWh usable battery.

To get 250 you need to be averaging 4.4 kWh

Whilst I can get that in my MG5 LR with gentle smooth driving it's usually closer to 3 with my heavy foot / mostly motorway miles.

170 - 230 miles range is 3 - 4 miles / kWh which is normal.

 

Welcome to the "Fooled by WLTP" club! Use percentage, which is more accurate on an EV.

 

Is there a better figure if you turn the car on > but the climate/air con fully off < ?

WLTP should always be read with. " for comparison purposes only" , but for some reason the marketing people forget this and let people think it's easy to get day in day out

I recall an old Audi 100 advert which pushed the "up to 1000km" dribe - at least they kept in the "up to" honesty bit which was supposed to let you know to read "test track conditions" in the small print.

take 2 cars, which one goes further in test track conditions ?

 

Had one of these for a couple of weeks, and it doesn't like cold/wind and is certainly much less efficient than my Ioniq 38kWh. However saying that, it is way bigger/heavier and less aerodynamic so to be expected, I am happy with te range at this time of year in these conditions and I certainly think as they only sensibly priced estate BEV it doesn't do a bad job, ran it down to 1% and it was ~233 miles completed with a mix of driving styles/speeds and weather. Seems to be slightly pessimistic at the higher % vs mileage shown.

Did you drive the MG ZS or MG5?

The MG5 LR is 1550 kg and the 38 Ioniq is 1602 kg, MG ZS LR 1695 kg according to ev-database. The drag coefficient is pretty decent too and comparable.

The Ioniq is far better in motor and battery efficiency though, probably the best out of any EV to date.

 

As alluded to in one of the earlier posts, weather conditions are a factor. Over Autumn and Winter ranges will reduce, even if you drive like a saint. It also depends on your heater (heat pump or no heat pump). At the back end of March when we had a mini heatwave(ish) my battery mileage went up considerably, but in miserable April it has dropped again. I suspect things will improve significantly if we get a proper heatwave. Driving conditions are also a factor, I live in Norfolk and there is not much in the way of dual carriageways and more often than not you get stuck behind a tractor using the A47 as a farm track, once I had an indicated over 8 miles per kW for the first 5 or so miles of a journey courtesy of a tractor that was probably classed as a vintage vehicle.

 

If you want the GOM to show WLTP then reset the long range trip, turn off fan and heater and put into eco mode.
After a full charge it should show a better figure, i believe thats how they do it for test drives.

 

For absolute clarity: your car does not 'have 249 miles of range', nor are you 'only getting 220 miles'. The car 'achieved 249 miles of range' under the standardised WLTP test cycle, and the 'estimated miles remaining' is showing 220 miles.

It is entirely possible to exceed the stated 249 miles by driving slowly in favourable conditions. I've come close to getting 280 miles from my standard range MG5. It's also possible to achieve under 150 miles if you drive fast in the cold. The estimate displayed on the dash will show a reasonable average, but shouldn't be relied as an accurate prediction because it cannot possibly know what journey you are planning or what the conditions will be.

 

Also worth saying - try turning off your climate control lol

 

From experience in my MG5 LR having the heater on full blast on the hottest setting will only take a few miles off the range.

For any other day or with AC in cooling the impact is negligible on normal journeys. Maybe a mile worth of range lost max.

With a very short range and tiny battery by today's standards like the old 22kWh usable LEAF it's a noticeable impact.

Not worth the sacrifice. 😅

Biggest impact is mashing your foot to the floor, or flicking between eco > normal > sport and harsh braking and acceleration. Or driving well above 70mph on the motorway.

 

Turning on my Climate in my E-Niro loses between 10 -15 miles of a full charge of around 290 miles so pretty insignificant to be comfortable.

 

I drive an MG5 Exclusive (2021) sr, my wife & I have just returned from a months holiday, North-East Scotland to Holy Island, Derbyshire, Liverpool, Dumfries and Galloway, Perth then home. Total mileage 1684, recharge cost £148.00 GBP. Depending on conditions we were getting a range of just over 200 miles to the charge at a constant 60mph with the odd heavy right foot to over the ton.
Just love the '5' comfy, roomy with plenty of oomph even in eco & regen 3, so comfortable that my wife falls asleep almost as soon as she gets in the car.

 

I also have just bought an MG5 LR Exclusive and also get a 220 miles charge.
I also am surprisinly pleased with the car which arrived with no defects and is comfortable and competent, if a bit dated externally (my wife prefers a 'not showy' car)
My one small complaint is the rear view camera - poor quality pictures.
The range suits my purpose and I am astounded by price/value compared to KIA EV6 and Hyundai Ionic5
I had ordered an EV6 but was taken aback by the confined cabin space during the test drive. This is a point I had not seen in reviews. While the KIA is a reasonable size externally, the 77 kW battery option seems to impose constraint on the driver's cabin space.
