The 2.3-liter 10-valve Volkswagen AGZ 2.3 VR5 engine was produced from 1996 to 2001 and was installed longitudinally on the Passat B5 model and transversely on the Bora, Golf 4 and Seat Toledo. This power unit, after upgrading the cylinder head to a 20-valve one, received a different AZX index.
EA395 or VW VR5 engines
The family of 5-cylinder Volkswagen VR5 EA395 engines was produced from 1996 to 2005 and was installed only on advanced versions of models on the Golf 4 and Passat B5 platforms. These power units are essentially an EA360 motor, but without one cylinder.
EA395 VR5 10v engines
In 1996, the VR-class engine cut down to 5 cylinders debuted on the Passat B5 model. In all other respects, the new unit completely repeated the already massive VR6 engine at that time: a cast-iron block with a camber of 15°, an aluminum cylinder head for 10 valves and a timing drive from two chains.
Unusually, the longitudinal and transverse aggregates had the same index:
- AGZ (10v, distributed injection, 150 hp / 205 Nm);
EA395 VR5 20v engines
In 2000, the power units of the VR5 family finally received a new cylinder head for 20 valves. There is also a modern ignition system, and the power and torque have grown.
This time, the power units of the longitudinal and transverse arrangement had different indices:
The 2.3-liter Volkswagen AQN 2.3 VR5 gasoline engine was produced from 2000 to 2005 and was installed on the Golf 4 and other platform models with a transverse engine. A similar power unit, which was installed longitudinally on the Passat B5, has the AZX index.
The 2.3-liter 20-valve Volkswagen AZX 2.3 VR5 engine was produced from 2000 to 2005 and was installed only on the fifth generation Passat and only in a restyled modification. A similar unit for a transverse arrangement under the hood is known under the AQN index.
