Third Generation of High-Response and High-Output 3.5L V-6 Engine

The VQ engine was developed as a lightweight, compact, low-friction and high-response engine in 1995. In 2002, a new 3.5-liter third-generation version will be introduced in the North American market. The major development aims set for the new-generation VQ35 engine were to improve output and to reduce noise and vibration, while maintaining the VQ's original features. This paper describes the technical approaches taken to achieve power output, noise and vibration improvements. In the design process, CAE modeling and virtual simulations were used in performing a cylinder-block stiffness analysis and an airflow efficiency calculation.
