VR5 Engine

Specifications

The Volkswagen VR5 engine is a unique naturally aspirated five-cylinder powerplant that blends compact design with smooth performance, using Volkswagen’s narrow-angle VR configuration. With a 2.3-liter displacement, it features a cast-iron engine block, aluminum cylinder head, and a 15-valve SOHC layout in early versions, later upgraded to a 20-valve DOHC design for improved airflow and efficiency. Power output ranges from approximately 150 hp to 170 hp, depending on the variant, with torque figures around 205–220 Nm, delivered in a smooth and linear manner.

The VR5’s narrow cylinder angle allows it to fit in tight engine bays typically designed for four-cylinder engines, while still providing the distinctive sound and refinement of a five-cylinder layout, making it a technically interesting and character-rich engine in Volkswagen’s lineup.

Engine Variants

AGZ (10-valve)

The AGZ engine was a naturally aspirated 2.3-liter inline-five petrol engine featuring a 10-valve SOHC cylinder head with two valves per cylinder (one intake and one exhaust). It delivered an output of 150 PS (148 hp) and around 205 Nm of torque, using multi-point fuel injection. The engine was known for its smooth power delivery, strong low-to-mid-range torque, and distinctive five-cylinder sound, making it well suited for everyday driving and long-distance comfort.

AQN / AZX (20-valve)

Manufactured between 2000 and 2006, the AQN and AZX engines were updated 2.3-liter inline-five petrol units featuring a 20-valve DOHC cylinder head with four valves per cylinder and variable valve timing for improved efficiency and performance. Power output increased to 170 PS (168 hp) with torque of approximately 220 Nm, while retaining multi-point fuel injection. These engines offered improved throttle response, higher rev capability, and better overall performance compared to the earlier 10-valve version, while maintaining the characteristic smoothness of the five-cylinder layout.
