Test – MG 5 Extended Autonomy: fuel consumption and autonomy

MG shows that station wagons have not yet said their last word. The MG 5 is the first to grab an electric motor and now goes to the lie detector.

Manufacturers generally see the electric car with two body styles: sedans or SUVs. In both cases, their larger size allows to carry a slightly larger battery than on compact or city cars, and this to better attract customers with a reassuring autonomy.

The Chinese manufacturer MG sees it differently and unveils the first electric station wagon with the MG 5. With its length of 4.60 meters, it is ideally placed between a Fiat Tipo and a Peugeot 308 SW. A compact estate car that could therefore be suitable for modest families (albeit) and for professionals in passenger transport such as taxis or VTCs. It remains only to prove itself in terms of autonomy, therefore subject of our Supertest.

Presentation of the MG 5

Data sheet

Our test model is therefore an MG 5 in the Extended Autonomy version. In this configuration, the estate has a Lithium NMC battery with a gross capacity of 61 kWh (57 useful kWh), which will allow it to announce 380 km of autonomy in its luxury top-class configuration. Like the MG ZS EV, the station wagon is powered by a synchronous front engine with a total output of 156 hp and a torque of 280 Nm. The power is again limited by that of the battery, when the entry-level version (50.3 kWh battery) peaks at 177 hp. Not enough to reduce performance, enough with a 0-100 km/h in 8.3s and a top speed of 185 km/h. It’s better than the SUV.

While there are many common numbers, they should not be confused. In this sense, the MG 5 here is based on a General Motor Delta II platform that has been modified from the previous Opel Astra. More precisely, it is the PATAC-K unit launched in 2015 and initially developed for perfectly thermal cars. The teams therefore had to make some adjustments, such as the raised edge to catch the suit in the floor.

On the loading side, the MG 5 refuels with an 11 kW AC on-board charger in series and a peak power of 87 kW in direct current. On the best public terminals or wallbox, it takes just under 4 hours to charge, while the 10-80% takes 30 minutes on the fast terminals.

All our consumption measurements of the MG 5

Mixed autonomy: 358 km

Upon their arrival on the European continent, Chinese manufacturers have widely put forward their aggressive price lists. However, the varnish burst from the first revolutions of the wheel with an equally aggressive consumption for the final autonomy. But MG was able to quickly acquire the necessary maturity in terms of efficiency, especially because the station wagon profile lends itself even better to the game. Admittedly, the temperatures during these measurements were mild with ambient air at 23°C, which is beneficial on consumption, although we made sure that the automatic air conditioning is set to 21°C. Air conditioning that, let’s take this opportunity to clarify, freezes your body at 20°C, but gives you the feeling of projecting lukewarm air at 21°C. It’s all the more unfortunate that you have to systematically go through the central touchscreen to juggle. That is.

Well helped by the weather, the MG 5 station wagon recorded an average consumption of exactly 15.9 kWh/100 km. With its 57 kWh battery, finally of medium size in the compact category, it has a range of 358 km. It’s just below the MG ZS EV and nearly 30 miles more than the Renault Megane e-Tech, tested anyway in the cold temperatures of March, let’s not forget.

In detail, it is in the city where the station wagon felt most comfortable with an average of 13.0 kWh/100. When the terrain becomes more pronounced, efficiency takes a hit and the counter quickly reaches a maximum of 30.0 kWh/100 km. In the fast lane, it showed a consumption of 19.2 kWh/100 km at an average speed of 105 km/h.

Road vs highway: a record for the moment

In these circumstances, there are also no surprises when passing our very favorable national road. Flat, without relief or almost and with few delays, allowing electric cars to give the best of themselves. Especially since if the weather follows, end consumption can quickly come first: with an average of 12.6 kWh/100 km (452 ​​km of autonomy), the MG 5 outperforms the Renault Megane e-Tech on the strict comparison of figures. Of course, with similar weather, the French could easily regain the advantage. But the performance is there.

On the highway with an average speed of 120 km/h over a distance of 50 km, appetite has increased to 21.5 kWh/100 km, or the equivalent of 265 km of autonomy. After all, the difference with what we found lies in the average: a lesser autonomy of 41.37% can be expected here between the most favorable and the least favorable of the existing routes.

Immediate consumption of the MG 5

Still in terms of exploring the performance in terms of consumption, the MG 5 did not escape our instant measurements at fixed speeds of 110 and 130 km/h. At the most modest speed on the highway, consumption is 19.5 kWh/100 km, or 292 km of total theoretical autonomy. If the tone is raised a little higher, the average rises to 24.0 kWh/100 km, or 237 km.

By reducing the speed, the theoretical range is thus increased by 21.66%. In the case of the MG 5, this corresponds to a range difference of 55 km, or 38 km on a “useful” full tank of between 10 and 80% load.

Immediate consumption – 23°C ext.
110 km/h 130 km/h
disadvantages average (kWh/100 km) 19.5 24.0
Theoretical total autonomy (km) 292 237

Long distance travel: 255 km range

But driving on the highway is not just about consumption at 130 km/h: the different delays, changing limits and topography always lead to lower consumption and thus greater autonomy. At the end of our 500 km journey between the suburbs of Lyon and Paris, we crossed the finish line with an average of 22.3 kWh/100 km. That is in this case 255 km of autonomy.

The MG 5 is 100% charged and can travel 230 km before charging 10%. Then it will be necessary to count on 180 km of autonomy between two stations on the highway, our measurement between 10 and 80% of the load. In short, nothing new in the tropics, the MG 5 is in the average of the other compacts, but with other practicalities.

Comfort and performance of the MG 5

And especially at the level of the trunk, it benefits with a very cubic capacity of 479 l. Each modularity is not really reflected in this station wagon, but you can still transport some more things with it than in a Volkswagen ID.3 or Renault Megane e-Tech. And he has nothing more to be ashamed of than in front of the 488 l of the MG ZS EV. But the break also doesn’t use the space under the trunk to carry a storage box, which could accommodate the charging cables. However, there is sufficient space under its imposing plastic plate. Unfortunately.

The interior has not suffered any criticism. A few surprising details are obvious, such as certain color choices, the creaking of the upholstery, the center console that burns the eyes with the reflection of the sun or the perfectable driving position. But the whole thing is pleasant. The digital instrumentation is complete and the central screen seduces with its speed, organization and definition. The soundproofing is correct, that’s all: our sound level meter indicated levels slightly higher than those recorded in a Megane, and persistent air sounds at the top of the uprights can be heard at high speed.

The MG 5 stands high on its wheels, which will not appear in the books of the most beautiful rims in history. This is the only solution the engineers have found to include the battery pack under the body. That does not create confidence if one refers only to appearance. But handling is surprisingly under control. Yes, the suspension is very soft and the Michelin Primacy 3st tires are average. But the title is stern, despite some pumping effects in support. However, the shock absorbers deserve better rebound guidance, while compressions resonate loudly in the body.

The locomotion is generally correct, but probably a little less on the fat/wet. The ESP takes care of the grain, but it must be said that the health of the engine is good. Count 8.3 s for 0-100 km/h and 5.75 s for 80-120 km/h at 80% battery. But the capacities decrease as the load decreases, without giving any visual signal to the dashboard about the remaining power: with a battery of 10%, the same exercise takes more than 13 s. An eternity in overtaking!

Supertest MG 5: the results

No one can match the Dacia strategy, especially not the Chinese manufacturers who, despite exotic price lists, are entering the SUV segment. But MG pulls the carpet from the bottom up and offers a car suitable for small families, or for those who need some luggage space without signing up for an imposing SUV. The MG 5 could easily be the spiritual descendant of the first-generation Dacia Logan MCV, which offers a pragmatic, adequate formula based on technical solutions already proven elsewhere.

But it is not a cheap vehicle, with a completely correct presentation and perfect handling. A good family car that keeps its promises in terms of autonomy and versatility. In any case, this is what its powers and charging times suggest, which should require more than one person to go on holiday, provided they are well prepared in the absence of a trip planner on board. We will come back to this with the second part of this Supertest.

If the Romanian break were suitable for modest homes, the MG 5 is not for all budgets and will not soon become the darling of families. Of course, it is in a good position compared to other proposals and offers convincing value for money. But we must not forget that in the Luxury version of the configurator alone, you have to sign a check for €37,490, which brings the ecological bonus to €31,490. The MG ZS EV with its larger battery requires an effort of just €1,500. Too bad the border isn’t better marked in favor of the MG 5…

What is the Supertest?

Lovers of numbers and allergic to official datasheets, the Supertest, the new test format from Automobile-Propre, is made for you and collects data collected during a test in real conditions and according to a transparent and precise protocol. We will add them on the Wednesday after the publication of the second part dedicated to the MG 5 Extended Autonomy to our summary article making it possible to compare the noted values ​​of the tested models, making all the head value.
