What reviewers say

Reviewers agree the MG3 is cheap and well equipped and the Hybrid+ quick, but its slow three-speed gearbox makes power delivery awkward at higher speeds. Autocar found the infotainment annoying and rear head room poor; What Car? found the ride firm and the cabin noisy, and cited its low Euro NCAP rating, while Auto Express rated its ride and refinement well.
