B207L is a water-cooled, 4-cylinder, 2.0 litre petrol driven in-line engine of aluminum with 4 valves per cylinder, 2 overhead camshafts and 2 balance shafts integrated in the cylinder block. It is crossflow type, i.e. the inlet is located on one side of the combustion chamber and the exhaust on the opposite side. Steel non-exchangeable cylinder liners are pressed into the engine block. The five main bearings are integrated in one common bed plate.

For low sound levels and compact size, the coolant pump is integrated in the balancer shaft chain circuit. The power steering pump and vacuum pump are driven directly via the camshafts. The engine is transversely mounted and is inclined 10° to the rear in the engine bay. The 2-litre capacity provides high torque even at low engine speeds, which is advantageous when driving in normal traffic conditions.
