This paper describes a new 4.5-Liter V8 engine, VK45DE, which was developed for the use in the Infiniti Q45 sporty luxury sedan. The VK45DE engine, the replacement of the VH41DE for the Infiniti Q45 2000 model, is a new generation V8 engine that produces high output power at top-end speed and also generates ample torque at low and middle engine speed. Furthermore, this engine achieved best in class quietness that is pleasing the customer throughout the range of loads and speeds. Development efforts were focused on how to highly balance the need for performance with the need for quietness and smoothness. This paper provides details of this VK45DE engine as well as highlights of individual technologies that support highly balanced performance of this engine.
