Character
1NR-FE
"The 1.33 petrol in the Yaris XP90/XP130, Auris and Corolla E150/E180, iQ, Urban Cruiser and Verso-S. Chain-driven, port injection, no turbo. German and French used-car data rate it durable, but it is known for oil consumption that grows with mileage, and engines run low on oil can fail. Check the dipstick and the service history."
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."
