Frequently asked questions
Which Peugeot 107 engine is the most reliable?
1.0 (1KR-FE) — Reliable verdict. The 1.0 VVT-i (1KR-FE — the legendary little Toyota three-cylinder, the same engine that powers the Aygo/107/108/C1 trio and turns up in the Yaris) is one of the most dependable engines in this whole catalogue: chain-driven, port-injected, no turbo and famously frugal and long-lived. It's slow, especially loaded or on hills, and three-cylinder-thrummy, but mechanically it just keeps going. The one historical caution is an early-life coolant/exhaust-stud niggle on some very early 1KR units, long since sorted. The honest, bulletproof city-car engine — buy on basic history and enjoy near-zero running costs.
