Mazda L engine
Mazda L engine
The Mazda L-series is a mid-sized inline 4-cylinder gasoline piston engine designed by Mazda as part of their MZR family, ranging in displacement from 1.8 to 2.5 liters. Introduced in 2001, it is the evolution of the cast-iron block F-engine. It was co-developed with Ford, who owned a controlling stake in Mazda at the time. Ford uses it as their 1.8 L to 2.5 L Duratec world engine and holds a license to develop engines based on the L-series in perpetuity.
