Frequently asked questions
Which Mazda CX-3 engine is the most reliable?
2.0 SkyActiv-G (petrol) — Reliable verdict. The 2.0 Skyactiv-G (PE, the naturally-aspirated mild-hybrid petrol shared with the Mazda 3) is the dependable, deliberately old-school choice — no turbo to fail, a timing chain, and Mazda's high-compression port+direct injection that largely sidesteps the heavy intake-carbon problems of pure-DI rivals. It's modest in a crossover (you work it on hills and loaded) and not the most economical naturally-aspirated unit, but mechanically it's one of the lowest-risk modern petrols you can buy. The honest, fuss-free pick.
