MG MG3

Supermini hatchback · 2013 to present

The MG3 is a budget-focused supermini that has been sold new in the UK since 2013, aimed at buyers wanting a straightforward small hatchback with a generous specification list and a long manufacturer warranty. The original MG3 used a simple 1.5-litre naturally aspirated petrol engine and was withdrawn from UK sale around the end of the 2010s as MG shifted focus to SUVs and electric models. MG revived the nameplate with an all-new, second-generation MG3 launched in 2024, built on a modern platform and offered in the UK exclusively with a full hybrid powertrain. Across both generations the MG3 has competed with established superminis such as the Ford Fiesta and Vauxhall Corsa, typically undercutting rivals on price while offering strong equipment levels. It remains a five-door-only hatchback throughout its UK history, with no diesel or convertible variants ever offered.

Fuel and powertrain options

The MG MG3 is sold in the UK with the following powertrain options across its current and recent model years:

Things to check at MOT

Below are common inspection items that owners and technicians often pay attention to on the MG MG3. These align with standard DVSA MOT criteria. Every individual vehicle is different, and the MOT history of a specific car can be checked on gov.uk using its registration plate.

Check for corrosion around the rear subframe mounting points and exhaust heat shields on older first-generation cars
Inspect front and rear tyres for uneven wear, which can indicate tracking or suspension bush issues
Test all exterior lighting and indicators, as bulb or wiring faults are a common minor fail point
Check the condition of front brake discs and pads, as these can wear faster on higher-mileage town-used examples
Verify the infotainment and dashboard warning lights function correctly, particularly on hybrid models with additional electronic systems

Frequently asked questions

Does the MG3 have a good MOT history?

Pass and fail rates vary by individual vehicle and age, so it's best to check the car's actual MOT history for free on the official DVSA website before buying.

Is the MG3 cheap to tax in the UK?

Road tax depends on the car's CO2 emissions and registration date, with the newer hybrid model generally benefiting from lower rates than the older petrol-only version. Always confirm current VED costs on gov.uk.

What engines does the UK MG3 come with?

The original MG3 used a 1.5-litre petrol engine, while the current, second-generation MG3 sold in the UK is offered solely as a full hybrid.

Is the MG3 a reliable used car choice?

Reliability varies by individual vehicle history and maintenance, so it's worth reviewing the specific car's MOT and service records rather than relying on general assumptions.
