Character
1NZ-FXE
"Toyota's first mass-market hybrid petrol engine (Prius NHW11/NHW20, Yaris Hybrid 2012-2020). An Atkinson-cycle 1.5 with a timing chain and an easy life thanks to the electric motor. Wear arrives late: oil burning past about 200,000 km and chain wear; on the 2004-2009 Prius the electric water pump was recalled. Check the recall and the oil level."
1KR-FE
"Toyota three-cylinder in the Aygo, Citroen C1, Peugeot 107/108 and Yaris. Simple, light and cheap to run with a maintenance-free chain. Watch two things: the water pump on 2005-2009 cars (an uprated pump came in 2009) and the oil level, which owners report dropping on some engines."
