VR6 Engine Configuration

Combining elements of both inline and V engines, the VR6 design offers a harmonious balance between performance and packaging efficiency.

The key feature of the VR6 engine is the narrow angle between its cylinder banks. Unlike V engines with wider angles, the VR6 engine features a tighter angle—usually around 15 or 10.6 degrees—which allows for a more compact overall size. This narrower angle enables the VR6 engine to fit within the engine bay of compact vehicles without sacrificing performance.

The VR6 engine’s cylinder arrangement is unique as well. It features two sets of three cylinders sharing a single cylinder head. This configuration allows for a more streamlined design, reducing the engine’s length compared to traditional inline engines with separate cylinder heads for each bank.

By combining the cylinders into a single cylinder head, the VR6 engine achieves improved airflow and combustion efficiency. The close proximity of the cylinders enhances the engine’s torque delivery, providing robust low-end power and a smooth power band throughout the rev range. This characteristic gives the VR6 engine a distinctive and engaging driving experience.

The VR6 engine series offers a range of displacements to cater to different performance requirements.
