The MG4 EV has a 363-litre boot with the rear seats up (about 350 litres on the Essence 77), expanding to 1,177 litres with the 60:40 seats folded. The load floor is wide, square and flat with no lip, plus a handy underfloor compartment for charging cables. It is average on paper but very usable in practice — and an underfloor tray plus a boot organiser make it far tidier.
MG4 Boot Space: The Numbers
If you are cross-shopping or planning a big load, here are the figures you actually came for. The MG4's boot is average in raw volume for the class but better than the numbers suggest, thanks to a square shape and no load lip.
| Measure | Figure | Note |
|---|---|---|
| Boot, seats up (standard) | 363 litres | Excite / SE and most trims |
| Boot, seats up (Essence 77) | ~350 litres | Long-range trim, slightly less |
| Boot, seats folded | 1,177 litres | 1,165 L on Extended Range & XPower |
| Seat split | 60:40 | Folds to a near-flat floor |
| Vehicle length / width / height | 4,287 / 1,836 / 1,504 mm | Compact-hatch footprint |
| Load lip | None | Flat entry, easy to slide items in |
For context, that 363-litre figure sits just behind a VW ID.3 (385 litres) and ahead of a BYD Dolphin (345 litres). You can confirm the current figures on the official MG4 EV page or in Parkers' practicality review. Numbers aside, the real issue owners run into is not volume — it is layout.
Why the MG4 Boot Feels So Shallow
On paper the MG4's boot is competitive. So why do so many owners feel like they are fighting for space? The answer is layout, not volume.
Layout, Not Volume
The MG4's boot is wide and reasonably deep, but the way the space is arranged makes it awkward. Items slide around on the flat floor, and the height available means taller items tip over rather than stack.
The result is a boot that holds a respectable 363 litres yet feels chaotic in daily use — shopping bags topple, cables tangle, and small items disappear into corners.
The "Floating Floor" Dilemma
The MG4 uses an adjustable boot floor that can sit high or low. In the high position you get a flat load lip but lose depth; in the low position you gain depth but create a step.
Neither position solves the core problem: without dividers or trays, the space is one big open box where everything moves around. That is where a proper storage setup earns its place.
The Fix: An MG4 Underfloor Storage Tray
The single most effective upgrade is an underfloor storage tray — it turns the wasted, awkward cable space beneath the floor into organised, usable storage.

What Is an Underfloor Tray?
An underfloor tray is a moulded insert that sits in the compartment beneath your main boot floor. It divides that space into sections, so your charging cables, tyre kit and small tools each have a home instead of rolling into one tangled pile.
Sorting Out Cable Chaos
Every MG4 owner knows the cable problem. Your Type 2 charging cable and granny charger are bulky, heavy and awkward. Left loose, they slide around the boot, tangle together and get in the way of your shopping.
A tray gives them a dedicated slot below the floor, freeing the entire main boot area for everyday loads and keeping the cables clean and accessible.
Is It Worth It?
For most owners, yes. An underfloor tray is an inexpensive upgrade that solves the single most annoying boot issue — cable chaos — while freeing up the main floor for actual cargo. It is the highest-impact change you can make.
Taming Daily Mess: The Right MG4 Boot Organiser
With cables sorted below, the next step is controlling the main floor — and that means a boot organiser sized for the MG4.
No More Rolling Groceries
The classic MG4 complaint: you get home and your shopping has slid the length of the boot, with eggs cracked and bags tipped over. A firm-sided organiser holds bags upright and stops them moving under braking and cornering.
Types of Boot Organiser
Organisers range from simple soft-sided caddies to firm, collapsible boxes with dividers. For the MG4, the best choice is a collapsible organiser with a rigid base and adjustable dividers — it holds its shape when loaded but folds flat when you need the full boot.
Does the Anti-Slip Base Actually Work?
A non-slip base is the feature that matters most. On the MG4's smooth boot floor, an organiser without grip just slides around itself, defeating the point. A rubberised or textured base grips the floor and keeps everything anchored.
The Complete System: Tray + Organiser
The tray and the organiser are not either-or — together they create a complete two-tier storage system that transforms the MG4 boot.
A "Two-Tier" Ecosystem
Think of it in layers. Below the floor, the underfloor tray holds cables, tools and the tyre kit — the heavy, occasional-use items. Above the floor, the organiser handles daily loads like shopping, bags and kids' gear.
The result is a boot where everything has a place, nothing slides around, and you still get the full flat floor by folding the seats when you need to carry something large.
Protecting Your Bumper
One more area owners overlook: the rear bumper top edge, which gets scuffed every time you slide something heavy in or out. A rear lower bumper protector guards that painted lip from scratches — cheap insurance for your resale value. Browse the full range in our MG4 accessories collection.
MG4 Boot Space & Storage FAQs
How big is the MG4 EV boot?
The MG4 EV boot holds 363 litres with the rear seats up on most trims (the long-range Essence 77 is about 350 litres), expanding to 1,177 litres with the 60:40 rear seats folded down (1,165 litres on Extended Range and XPower models). There is also a useful underfloor compartment for cables.
What are the MG4 boot dimensions?
The boot opening is a usefully square shape with no load lip, which makes it more practical than the 363-litre figure suggests. The car overall measures 4,287mm long, 1,836mm wide and 1,504mm high. The wide, flat floor easily takes a single buggy or a large suitcase.
Is the MG4 boot big enough?
For everyday family use, yes — 363 litres handles a weekly shop, a pram or airport luggage, and the square shape uses the space well. It is slightly smaller than a VW ID.3 (385L) but the flat floor and underfloor storage make it practical. If maximum boot space is your priority, the MG4 Urban trim offers far more.
Does the MG4 have underfloor boot storage?
Yes. There is a dedicated compartment beneath the boot floor, primarily intended for the charging cables so they do not roll around the main load area. An underfloor storage tray organises this space so cables and small items stay tidy and separated.
How do I get more usable space in my MG4 boot?
Three steps: use the underfloor compartment for cables to free the main floor, add a boot organiser to stop shopping sliding around, and fold the 60:40 rear seats for large loads (up to 1,177 litres). A tray-plus-organiser system gives you tidy everyday storage without losing the flat load floor.
What is the best boot organiser for the MG4 EV?
The best organiser is one cut to the MG4's boot width with a firm, non-slip base and collapsible dividers, so it holds shopping upright but folds flat when you need the full space. Pair it with an underfloor tray for a two-tier system: cables and tools below, daily items above.
Will a tray still leave room for my charging cables?
Yes. A well-designed underfloor tray organises the cable compartment rather than filling it — it separates your Type 2 and granny cables from other items so they are easy to grab and do not tangle, while still fitting within the factory underfloor space.
Reclaim Your Boot
The MG4's 363-litre boot is not the problem many owners think it is — the raw space is competitive, and folding the seats unlocks 1,177 litres. The real issue is organisation: loose cables below and sliding loads above.
Fix both with a two-tier system — an underfloor tray for cables and a non-slip organiser for daily loads — and the MG4 boot goes from chaotic to genuinely practical, without spending much or losing any of your factory space.
