MG4 Weight: The Complete Guide to How Heavy the MG4 Really Is

Electric cars are reshaping the way we think about weight, balance, and real-world performance — and the MG4 is one of the best examples of this shift. When we talk about MG4 weight, we’re not just discussing a number on a spec sheet. We’re talking about how the car feels on the road, how it handles tight roundabouts, how it accelerates silently from a junction, and how much energy it burns to get you from Point A to Point B.

In this complete guide, we explore the MG4’s weight figures across all trims, why the car weighs what it weighs, how its mass compares to rivals, and what that means for everyday driving. We take a casual but authoritative approach — as though we’re sitting inside the car with you, pointing out each detail as it matters.

Let’s dive in.

Understanding MG4 Weight Across Trims

The MG4 lineup has several trims and battery sizes. Each brings a slightly different weight depending on equipment, battery capacity, and added technology.

MG4 Weight by Trim (Approximate Kerb Weights)

These figures vary slightly by market, options, and wheel choices, but they give us a clear sense of how the MG4’s structure scales with battery size and performance components.

Why Weight Matters So Much in the MG4

Weight shapes everything from acceleration to range. In electric vehicles, weight is especially important because the battery accounts for such a large portion of the car’s mass.

Weight Influences:

• Range — heavier batteries = more stored energy, but also more mass to move
• Handling — low-mounted weight improves cornering stability
• Efficiency — every extra kilogram affects real-world consumption
• Acceleration — the motors must work harder with more mass
• Tyre Wear — heavier EVs are known to wear tyres faster
• Braking Distance — mass directly impacts stopping performance

We can summarise this with a simple concept:
EV weight is a blessing and a curse — stability increases, but efficiency takes a hit.

Where MG4 Weight Comes From

The MG4’s weight is not random. It is distributed across a carefully designed architecture: the SAIC Nebula platform. The main contributors to the MG4’s mass include:

1. The Battery Pack (Largest Contributor)

The single heaviest component by far.

• 51 kWh pack: lighter, cheaper, more efficient
• 64 kWh pack: balanced range and weight
• 77 kWh pack: significantly heavier

2. The Electric Motor and Power Electronics

Motor + inverter + reduction gearbox add notable mass.

3. The High-Strength Steel Chassis

EVs require extremely rigid platforms to handle the battery load.

4. Safety Systems

Crash structures, reinforcements, airbags, sensors — all add grams that become kilograms.

5. Interior Equipment

The Trophy trim has more tech, more features, and thus, more weight.

MG4 Weight vs Rivals

Let’s compare the MG4 to competitors in the compact electric hatchback/crossover space.

Weight Comparison Table

The MG4 positions itself on the lighter side of the EV segment — impressive considering its price point and generous equipment.

How Weight Affects MG4 Range

If you’ve ever driven an MG4 across mixed terrain, you’ll know its range is influenced heavily by the model’s weight. Here’s how each weight level impacts real-world performance.

MG4 Charger Type – The Complete Guide to Understanding How the MG4 EV Charges

MG4 Standard Range (51 kWh, ~1,655 kg)

• Best efficiency in the lineup
• Lightest battery = easiest acceleration
• Good urban range

MG4 Long Range (64 kWh, ~1,680–1,700 kg)

• Sweet spot for weight vs capacity
• Balanced motorway and city performance

MG4 Extended Range (77 kWh, ~1,800 kg)

• Heavy battery but excellent motorway endurance
• Slight efficiency penalty in town

MG4 XPOWER (~1,800 kg)

• Massive performance
• Weight offset by dual motors
• Efficiency drops if driven aggressively (and it will be!)

Does Weight Affect MG4 Handling?

Absolutely — but mostly in a good way.

Thanks to its low centre of gravity, the MG4 handles like a heavier hot hatch that actually enjoys being pushed.

Handling Pros of MG4 Weight

• Stable at high speeds
• Predictable body roll
• Planted during sweeping corners

Handling Cons

• Quick direction changes feel “dense”
• Light steering masks the car’s actual mass
• Trophy trim feels slightly heavier on tight city manoeuvres

Weight Distribution: The Secret Sauce

The MG4 features near-perfect 50:50 weight distribution.
That’s sports-car territory.

This happens because:

• The battery sits low and centered
• The motor is at the rear axle
• No heavy engine at the front

This symmetry gives the MG4 an unexpectedly engaging driving feel — something reviewers often highlight more than its acceleration numbers.

How MG4 Weight Impacts Braking

More mass means longer braking distances, but the MG4 counters this with:

• Regenerative braking
• Strong disc brakes
• Good tyre grip

Regenerative braking also recaptures energy, but heavier trims (77 kWh and XPOWER) need stronger regen to match the deceleration feel of the lighter models.

MG4 Towing and Payload: Weight in Practical Use

While the MG4 is not designed as a towing champion, weight still influences what it can safely pull.

MG4 Towing Capacity

• Light towing only
• Varies by market (typically limited)

Roof Load

• Usually around 50–75 kg depending on accessories

Payload

• Around 400–450 kg

Because EVs are heavier by nature, payload numbers tend to be tighter compared to petrol models.

Weight and Tyre Life: What You Should Know

Heavier cars eat tyres faster — that’s EV life.

MG4 drivers often report:

• Front tyres last 20,000–30,000 miles
• Rear tyres (where the power goes) last slightly less on spirited drivers
• XPOWER can chew through tyres very quickly

Weight + torque = tyre bills.

MG4 Weight and Charging Efficiency

Here’s a fun fact:
Heavier MG4 versions often charge slightly less efficiently.

This is because:

• Heavier batteries heat up differently
• More mass increases rolling resistance
• Energy per mile goes up

Still, MG4 charging remains competitive in its class.

• Mass
• Power
• Repair complexity

Heavier EVs generally land in higher groups because repairs involve more specialised structural components.

In most regions, MG4 sits in:

• Group 27–30 depending on trim

The heavier XPOWER sits even higher.

Can You Reduce MG4 Weight?

Not meaningfully. But you can avoid adding unnecessary weight:

Tips

• Don’t leave heavy items in the boot
• Remove roof racks when not in use
• Choose SE trim if maximum efficiency matters
• Use lighter aftermarket wheels (if approved)

Weight reduction always feels good — even if the impact is small.

MG4 XPOWER: When Weight Meets Power

The XPOWER trim is the perfect demonstration of how EV weight can be turned into performance.

At ~1,800 kg, it still does:

• 0–62 mph in 3.8 seconds
• Launches harder than most petrol hot hatches
• Feels planted thanks to its mass + dual motors

This is where weight transforms from “efficiency penalty” into “performance glue.”

Is the MG4 Too Heavy? Our Verdict

All EVs are heavier than their petrol equivalents. But the MG4 uses its mass wisely:

• Low centre of gravity
• Balanced weight distribution
• Solid efficiency for its class

We’d argue the MG4’s weight is not a flaw — it's a characteristic that shapes its personality, much like a good song shaped by deep bass.

If you’re used to light petrol hatchbacks, the MG4 may feel hefty at first. But within a few days, that planted stability becomes second nature.

Closing Thoughts

The MG4’s weight is more than a number — it’s a story:
A story of engineering choices, battery architecture, handling dynamics, and EV practicality. Whether you choose the lighter SE Standard Range or the heavyweight XPOWER, the MG4’s mass is a deliberate balance of range, safety, performance, and driver confidence.

In an EV world where every kilogram counts, the MG4 proves that thoughtful weight distribution can turn a heavy car into a light-footed companion.
