2025 MG3 – Supermini Hatchback (All-New Generation)
1. Vehicle Overview
The MG3 has been MG’s value-packed supermini since its debut in 2013, and for 2025, it has been completely reinvented. The all-new second-generation MG3, launched in early 2024, enters the competitive supermini hatchback segment with modern hybrid technology, a more premium design, and MG’s trademark affordability.
Built to take on rivals like the Toyota Yaris Hybrid, Renault Clio E-Tech, and Hyundai i20, the new MG3 blends city-friendly agility with low running costs and a well-equipped interior. It’s MG’s first full-hybrid (HEV) model in Europe — not a mild hybrid, but a true petrol-electric system capable of electric-only driving for short distances.
