    MG One Revealed With Brand New Sigma Platform

    by Mahesh Yadav on Wednesday, Aug 04 2021

    MG recently revealed their new MG One SUV. This new car uses the brand’s all-new Sigma platform. The new modular platform uses more than 100 substructures, which allow MG to adapt it to any body style and all of the new generation engine-transmission configurations in MG’s pipeline.

    MG Sigma Platform Body Styles

    The MG Sigma platform is capable of becoming the base for any of the following body styles:

    Body Style



    Tata Altroz, Hyundai i20

    Notchback (sub-4m sedan)

    Maruti Dzire, Tata Tigor

    Small SUV

    Kia Sonet, Tata Nexon

    Mid-Size SUV

    Hyundai Creta, Kia Seltos

    Large SUV

    Hyundai Alcazar, Tata Safari


    Mahindra Thar, Force Gurkha

    Mid-size sedan

    Honda City, Hyundai Verna

    Sports Car

    Mazda MX-5, BMW Z4


    The modular platform can transform into pretty much any imaginable body form allowing MG the flexibility to adapt to evolving market demands. For instance, if the demand for sedans increases, MG can quickly bring a sedan to market. If there’s demand for a sports car, MG can launch a new sports car with a very short turn-around time.

    MG Sigma Platform Powertrain Options

    That’s not all. MG are working on a new generation of powertrains for the future and all of those will work with the Sigma platform. The new frame can accommodate normal petrol, turbo petrol, petrol hybrid as well as electric drivetrains. It’s unclear at the moment if MG are also working on diesel engines for India. However, the fact that this platform is suitable even for off-roaders tells us that MG may have some new diesel engines in the pipeline. That’s because off-roaders generally need a lot of torque and diesel engines offer that by the bucket loads. Alternatively, MG could meet all that extra torque demand with electric motors - either in hybrid or all-electric format.

    MG One and Sigma Technology Features

    The MG One also has a flat rectangular part hiding in the bumper. So, we can say that on the technology side, at least some Sigma architecture cars could come with advanced driver assistance features such as:

    • Radar-based adaptive cruise control
    • Full automatic emergency braking
    • Lane keep assist
    • Lane change assist
    • Bline-spot monitoring
    • Automatic parallel and perpendicular parking
    • Auto-follow and crawl in traffic

    In addition, we can also expect the Sigma-based cars to come with telematics features. MG have recently announced a partnership with Reliance Jio

    On the packaging front, the new Sigma frame leaves up to 70% of the car’s volume to the occupants in the form of cabin or storage space.
