MG IM5: Long Range or Performance?
Both use a 100kWh battery. Long Range prioritises distance between charges; Performance adds a second motor and all-wheel drive. Here is how to choose the IM5 that fits your week.

UK figures checked 22 October 2026 against MG’s IM5 specification data and Invicta’s current variant pages. Prices are listed OTR figures before individually quoted options; finance offers are separate. WLTP is a comparison test, not a promise of road range.
Choose Long Range for fewer charging stops
The Long Range has an 84-mile advantage in the published combined WLTP figures. If you regularly drive between cities, that extra rated range is a practical reason to start here.
It is already a powerful car: the manufacturer quotes 407PS and 4.9 seconds to 62mph. The decision is whether you would use the Performance model’s extra response often enough to prefer it to the longer official range.
Base your charging plan on the journeys you actually make. Winter weather, speed, cabin heating and load can all reduce the distance available from either version.
Choose Performance for its dual-motor character
Performance combines front and rear electric motors with all-wheel drive. Its 751PS output and quoted 3.2-second acceleration are the clearest reasons to choose it.
The larger Sport wheels also change the specification you are buying. Compare wheel and tyre sizes, replacement costs and ride preferences on your normal roads, rather than choosing from the acceleration figure alone.
All-wheel drive does not remove the need for appropriate tyres, sensible speed or adequate stopping distance. It is one part of the vehicle’s behaviour, not a guarantee of grip in every condition.
Charging is a shared strength
Both 100kWh versions use MG’s 800V electrical architecture. MG quotes 10–80% charging in 17 minutes using a suitable 350kW ultra-fast charger under standardised conditions.
That is a charging-session comparison, not a guaranteed stop length. Battery temperature, starting charge, charger capability and shared site capacity can affect the result.
The lower-priced 75kWh Standard Range is a different specification. Its quoted 26-minute charging time should not be substituted for these two 100kWh cars.
The cabin does not become bigger with Performance
MG lists the same 457-litre luggage volume for these two versions, rising to 1,290 litres with the rear seats folded, plus an 18-litre front compartment. Choosing Performance does not add passenger seats or luggage capacity.
Bring your regular luggage or pushchair to a viewing. Opening size, bag shape and access matter as much as a litre figure, particularly if the rear seats need to stay in use.
Try your driving position and rear-seat comfort before discussing upgrades. A more powerful motor cannot compensate for a seat or storage arrangement that does not suit your routine.
Make the £3,500 difference work for you
At the listed prices above, Performance costs £3,500 more. Request written quotations with the same paint, accessories and purchase method so that you can see what changes the final total.
For regular longer journeys, start by considering Long Range. For an owner who specifically wants the dual-motor response and all-wheel drive, Performance is the clear alternative.
Ask Invicta MG to confirm the exact available specification and a suitable appointment. Compare current MG offers separately from the car’s underlying OTR price.
Your questions answered
Do both versions have the same battery?
Both are labelled 100kWh; MG’s specification lists 96.5kWh usable capacity. The 75kWh Standard Range is a separate version.
Which IM5 has all-wheel drive?
The 100 Performance. The 100 Long Range is rear-wheel drive.
Is 441 miles the range of the Performance?
No. Up to 441 miles WLTP applies to Long Range; Performance is quoted at up to 357 miles WLTP. Actual driving range varies.
Does the 17-minute charging claim apply at home?
No. It is a 10–80% DC ultra-fast charging test figure for suitable conditions and equipment. Home AC charging takes considerably longer.
