The VW R32 is a 3.2-liter VR6 naturally aspirated gasoline engine well known by VW Golf R32 mk4/5 model application. In addition, the engine was used on other Volkswagen models as well as Audi. The R32 engine is a member of the Volkswagen’s EA390 family.

The 3.2 VR6 has a grey cast iron cylinder block with narrow 15 degrees angle between cylinders banks. The cylinders are moved by 12.5 mm from the center of the die-forged steel crankshaft. In this case, there is a 120 degrees firing interval between each cylinder. The crankshaft has seven main bearings.

Due to the narrow V-angle, the need for separate cylinder heads for each cylinder bank was gone. The R32 has a single aluminum alloy head and double overhead camshafts (DOHC). The engine has a timing chain (simplex roller chain). The engine has four valves per cylinder, 24 valves total. Each camshaft has 12 cam lobes, so the front camshaft actuates the all intake valves, the rear camshafts – the exhaust valves. The valvetrain is equipped with low-friction roller finger cam followers with automatic hydraulic valve clearance adjustments. The 3.2L VR6 engine has variable valve timing (continuous timing adjustment) for both camshafts (52 degrees on the intake at the front, 22 degrees on the rear exhaust camshaft).

The engine has an electronically controlled variable intake manifold; it is a twin-path intake manifold. This engine has a traditional sequential multi-point fuel injection. The six injectors are mounted on the intake manifold ports and normally hidden behind the top part of the intake manifold. There are two cast iron exhaust manifolds from the back side of the engine. The 3.2 VR6 engine equipped with an electronic ignition system with six individual single spark coils for each cylinder. The engine also has an electronic drive by wire throttle body. The engine operation is controlled by electronic engine control unite (ECU) Bosch Motronic ME 7.1.1.
