MG HS PHEV mpg/range with battery depleted / Engine only

Just checked the Australian MG site, and there is no hybrid model for the HS anymore. It's not even "coming soon".

Correct. There is no hybrid model (PHEV) on the MG Australia web site. Interested to learn from you that it will "not be coming soon". This is what I read : perhaps June 2025?

Hi Phil -
This article appeared in DRIVE last year. It says,
"Head of Product at MG Motor Australia Akshat Ahuja said both a hybrid and plug-in hybrid (PHEV) variant of the MG HS will arrive in Australia by June 2025."

Let's hope so then. Because the new petrol HS is shown on the site.

And two weeks later, the new HS PHEV appears on the Australian MG site.

I have one that is 5 months old done 3,300 miles and is in showroom condition I paid £33,500 cash for it, all the Tweaks done such as uv tinted front glass mud flaps and side steps, body & wheel protection done too £29,000 if your interested?

It does around 3.4 miles per british pound. It's easier using mpp than mpg due to electric. The car is a real fuel guzzler and although it's a nice car to look at it's horrendous on fuel especially in towns and city's where the mpp is even less. Also worth noting a lot of the 'standard' features are missing

Hi JWPALFREY. This is a great question as I am interested in a MG HS PHEV Trophy and was curious what the MPG for the engine only is as occasionally we do long trips to Cornwall / Scotland (from East Anglia) and the battery will have dropped to low well on the way. It sounds like owners of the new model (mid 2024+) are getting 38ish which is what the spec says so am still a little sceptical. Welcome anymore thoughts on this. Did you ever do your 24hr test drive?

Hi Captin 1234x:
Those are very long journeys : e.g. Norfolk to Cornwall is around 650 km. I will try and answer as best I think, or know.
I live in Sydney, have never done anywhere near 650 km in one hit, but will try and give some figures in "our language". Please note these are for the 2022-23 models sold in Australia / NZ, which I drive, and would be DIFFERENT to the 2025 model specs you might buy in the UK (only just arriving in Australia).

The journey starts in my 2023 MG HS PHEV with a full charge = 63 km. And with a full tank = 37 litres.** We are driving on mostly open roads, (M11, M25, M4, M5).

1. The first 410 km.

• The battery has charge and is assisting the 1.5L turbo ICE (so we are driving on both; and that hybrid drive is termed "auto" in this MG car). That reading of 63 km charge will drop by 1 km for every 6.5 km you drive on those open roads. (We will be getting some regen on deceleration as we drive along). We could be down to a reading of 1-2 km charge left after this 410 km.
• The petrol in the tank will deplete for that 410 km journey on hybrid drive by about 4.9 litres per 100 km : so it will deplete by 20 litres from 37 to 17 litres, during that 410 km.

2. The last 240 km.
If you have not recharged the battery, and the battery is of little assistance as you continue the six and a half hour drive from Norfolk to Cornwall the petrol consumption could be around 8.0 litres per 100 km during this last 240 km. Why? Because you are just driving a petrol car while carrying an ADDITIONAL 240 kg of the car's "electrical stuff".

Having said all that, the MG HS PHEV is a good drive, with power, space, and comfort. So far, it has given me zero trouble.

Hi, Many thanks for your reply, this is really helpful. I am 6'4" (192cm) and have found the HS one of the few really comfortable cars to sit in and the interior space means the people behind me are OK as well. So I agree although there is better MPG out there for long runs, I like the idea of a good drive. Very likely to go ahead unless something even better comes along

Hi Captin1234x.

In my note last week I gave these figures for open road driving - almost entirely on motorways - driving in hybrid mode, starting the journey with a full tank of fuel and a full charge on the battery.
- The 16.6 kWh battery depletes down to almost nil charge after around 410 km : in other words the consumption reading is 4.05 kwh per 100 km driven.
The charge reading (which starts at 63) drops by 1 for every 6.5 km the car is driven.
- The petrol consumed in that 410 km journey would be 20 L : in other words the reading would show consumption of 4.9 litres per 100 km driven.

Later this week I am doing a clean, open road run, on the motorway for 120 km and will make a careful note to see whether those two are correct or not:
1. 4.05 kwh per 100 km driven.
2. 4.9 litres per 100 km driven.
Will keep you informed (and would also like to double check for myself).
------
Bear in mind, the car you are likely to buy is the 2025 model, not my 2023 model MG HS PHEV.
The new 2025 car has :

• a much higher pure EV range of 75 miles (120 km).
• a 2 speed gearbox, unlike the old MG HS PHEV with a 10 speed DCT gearbox.

Hi Captin1234x.

I lot of what I gave you earlier appears to be incorrect. My apology. This is what I noted on some actual trips. I have done more long-distance driving and made careful notes. Here it is….

Long Distances on MOTORWAYS in hybrid (“auto”) mode.

- Average speed travelled 105 km per hr. (65 mph).

- The 16.6 kWh battery depletes @2.1 kWh per 100 km of travel (2.1 kWh for every 62 miles travelled).

- The full battery charge starts at 62-63 km reading (for EV only driving), drops by 1 for every 13 km, to drop down to 2-3 km reading after about 780 km (485 miles) of travel in hybrid (“auto”) mode. So, the fully charged 16.6 kWh battery is almost fully consumed after about 780 km (485 miles) of travel on MOTORWAYS in hybrid mode. Seems ok for you to complete the full 650 km (404 miles) journey East Anglia – Cornwall, without any need to recharge the 16.6 kWh battery.

- The petrol consumption on this long motorway drive in hybrid (“auto”) mode is around 6 L per 100 km of travel (47 MPG - UK).

Long Distances on URBAN ‘B’ roads in hybrid (“auto”) mode.

- Average speed travelled 37 km per hour (23 mph)

- The 16.6 kWh battery depletes @6.5 kWh per 100 km of travel (6.5 kWh for every 62 miles travelled).

- The full battery charge starts at 62-63 km reading (for EV only driving), drops by 1 for every 4 km travelled, to drop down to 2-3 km reading after about 245 km (152 miles) of travel in hybrid (“auto”) mode. The fully charged 16.6 kWh battery (if not recharged), would be almost fully consumed after about 245 km (152 miles) of travel on URBAN ‘B’ roads in hybrid mode.

- The petrol consumption on these longer drives on Urban ‘B’ roads is around 5.5 L per 100 km (51 MPG - UK). A lot of the low speeds, slowdowns, traffic lights, round abouts etc is done on the HV battery, with little petrol use.
-------------
The new car (2025 MG HS Plug-in) available in the UK has just won car of the year 2025 for plug-in hybrids category at ‘WHAT CAR?’ It has a driving range in ‘EV Only’ of 120 km (75 miles) which is almost double my (2023) car in Australia. Given that range - you should be consuming virtually zero petrol on a weekly basis – as you do not drive to Cornwall every week! With MANY short, daily, weekly, local trips [under 100 km, in EV only], and some long trips out of town, you could easily get Combined 2.2 litres/100km (141 MPG-UK).
See this Annual Example below:

• 6 round trips to Cornwall = 1300 km x 6 = 7800 km (4847 miles). 6 x 78 L = 468 L of petrol. That is 6 L per 100 km (47 MPG - UK).
• 330 local round trips in hometown, and around hometown, each trip less than 105 km ( 65 miles) = ZERO litres of petrol (all done on EV only). Distance travelled : say 330 trips x 40 km average = 13200 km (8202 miles).

Total annual distance 13200 + 7800 = 21,000 km (13,049 miles).

Total Petrol consumed = 468 L = 103 UK gallons.

Consumption averages 2.2 L per 100 km or 128 MPG (UK).

Hope that is helpful.

The all new MG HS PHEV has a full 55 litre fuel tank along with a 75 mile EV range, the set up on the new HS PHEV is different, in the case that even at higher speeds the wheels are being driven by the electric motor, with the engine providing charge and driving support, it only has a 2 speed gearbox also, unlike the old HS PHEV with a 10 speed DCT gearbox

Bear in mind, most people will be talking about the old model HS PHEV, rather than the All New HS PHEV that launched mid 2024

It’s not a DCT gearbox. It’s a full auto six speed which combines with an electric motor, with four speed gear
