Expert Rating

MG 3

(2014 – present)

    Summary


    The MG 3 (styled as MG3) is a small, supermini-class, five-door hatchback. It was launched in the UK back in 2014, with a major facelift arriving in 2019.

    The MG 3 rates very much at the bottom end of the small car segment, based on 19 reviews we have analysed from across the UK motoring media. As of August 2023, it has a very poor Expert Rating of 40% – making it the lowest ranked supermini in our Expert Rating Index now that the Mitsubishi Mirage has been discontinued.

    There is very little to recommend the MG 3 over any other similarly-priced small cars. It had a sub-par three-star safety rating when it was tested by Euro NCAP seven years ago, and that rating has now expired because the car doesn’t even meet the required standard for a three-star rating anymore.

    As a used car, it might be worth looking at if the price was low enough, but the MG 3 doesn’t stack up as a new car. The new Dacia Sandero is both significantly cheaper and significantly better (although it has its own safety concerns), while more expensive rivals are both better and safer.

    MG 3 highlights

    • Seven-year new car warranty
    • Attractive low-cost pricing
    • Decent cabin space
    • Appealing exterior update
    • Agile handling

    MG 3 lowlights

    • Poor engine quality

    Safety rating


    Independent crash test and safety ratings from Euro NCAP

    No safety rating

    The MG 3 was crash tested by Euro NCAP back in 2014 and achieved a three-star rating. However, this rating expired in January 2021 and is no longer valid.

    Euro NCAP’s crash testing standards are raised almost every year, and ratings will expire when a vehicle no longer meets the latest standards for that rating. Sometimes a vehicle will be re-tested against the newer standards and awarded a new (usually lower) rating, but this has not happened in the case of the MG 3.

    Eco rating


    Independent economy and emissions ratings from Green NCAP

    No eco rating

    As of August 2023, the MG 3 has not been lab tested by Green NCAP. The MG 3 is now an old car, so it is likely that it will never be tested by Green NCAP. If it does ever happen, we’ll update this page with the results.

    Reliability rating

    As of August 2023, we don’t have enough reliability data on the MG 3 to generate a reliability rating.

    The Car Expert’s reliability information is provided exclusively for us using warranty data from our partner, MotorEasy. As soon as MotorEasy has sufficient data on the MG 3, we’ll publish the score here.

    Running cost data provided exclusively to The Car Expert by our data partner Clear Vehicle Data displays that, while the MG 3 is an ageing car that struggles when compared to other budget options like the Dacia Sandero, it is certainly cheap to run and maintain.

    Only available with a petrol powertrain, the MG 3 has an average fuel consumption of 43 mpg, which is surpassed by several newer hatchbacks like the Dacia Sandero and Volkswagen Polo by 10 mpg or more. If you decide to opt for this MG however, the service and maintenance costs are quite affordable when compared to the market as a whole, as is the car’s insurance.
