About the MG IM5
The MG IM5 is a fastback saloon that signals MG's move upmarket with the IM (Intelligent Mobility) sub-brand developed in collaboration with SAIC's premium Zhiji division. Available with battery options from 73.5 to 96.5 kWh, it offers up to 435 miles of WLTP range in its most efficient configuration — a remarkable figure that would make it one of the longest-range EVs in its class.
The IM5 features a sleek, low-slung design with a full-width light bar and fastback roofline. Inside, it moves significantly beyond the budget MG interiors of the past with a large central touchscreen, digital instrument cluster, and materials that aim to rival European premium brands.
DC fast charging at up to 250 kW enables a 10–80% charge in around 22 minutes. The IM5 is positioned against the Tesla Model 3 and BMW i4, offering competitive specifications at a potentially significant price advantage. Available in single and dual-motor configurations, it represents MG's most ambitious electric vehicle to date.
What the press thinks
Early reviews of the IM5 are cautiously impressed. The range figures, charging speed, and value proposition are highlighted as key strengths. Reviewers note the significant quality improvement over previous MG EVs. Questions remain about how well SAIC's premium aspirations translate to the European and Australian markets.
