The fourth-generation Mazda 3, launched in 2019, certainly looks special. As well as a hatchback body style, it’s also offered as a four-door saloon with a very striking fastback design. In e-SkyActiv-X mild-hybrid form, it aims to offer efficient running alongside an engaging drive. How well does it compare with rivals such as the Audi A3 saloon and Mercedes-Benz A-class saloon? Find out in our full Mazda 3 Saloon review.
