Frequently asked questions
Which Ford Focus III engine is the most reliable?
1.6 Ti-VCT (petrol) — Reliable verdict. The naturally-aspirated 1.6 Ti-VCT (Sigma family) is the simple, dependable petrol — port-injected, largely vice-free and good for 200,000+ km on basic servicing. One correction worth knowing: it's TIMING-BELT driven (interference), not chain, so it needs a belt service on schedule. The signature watch item is the variable-cam-timing (VCT) phase shifters: as they wear they clank/rattle on a cold start and clear as the engine warms, with acceleration tailing off — replacement territory at high mileage. Add minor oil-seal weeps and the odd coil/thermostat and that's the lot. Modest on power (adequate, not quick), but the stress-free choice if you don't need a turbo or diesel.
