Character

1.8 TDDi / DI (Endura-DI)

"Pre-common-rail Ford 1.8 diesel (Focus Mk1 TDDi 75/90 hp, Fiesta Mk4 1.8 DI). Direct injection with an electronically controlled rotary pump. Owners rate it far better than the later 1.8 TDCi; the injection pump and its control unit are the one known weak point, typically after 120,000 km."

Sigma 1.25

"Fiesta/Ka. Simple Yamaha co-developed engine. Timing chain (good). Reliable. Low power. Thermostat housing. Coil pack. Perfect first car/city car engine."
