1NR-FE

The 1NR-FE is a compact inline four piston engine featuring Stop & Start technology and

. It was introduced into the European market in late 2008 with the Yaris XP9F. Improved engine performance combined with low emissions and fuel consumption was the principal aim during its development. Advanced engineering has been applied throughout the 1NR-FE engine. Toyota engineers streamlined the engine's intake channel, used computer simulation to optimize airflow, smoothened all surfaces for less turbulence and rounded off all angles and sharp edges inside the engine. One of the key elements of the 1NR-FE engine is its piston design. Smaller and lighter than on the previous unit, they are designed with a smaller contact area and use carbon ceramide, an advanced material commonly used in Formula One engineering, to reduce friction. The engine also features cooled
