M20B25

The German version of the M20B25 produced 170 hp (130 kW) with a catalytic converter and 171 hp (128 kW) without. It featured the newly designed "885" head featuring an open, higher-volume combustion chamber design. The new engine had an 84 mm (3.3 in) bore, and 75 mm (3 in) stroke. The redesigned pistons and combustion chambers made better power, resisted detonation better and had higher thermodynamic efficiency. It was equipped with Bosch Motronic 1.1/1.3 Adaptive fuel injection. The new 12 valve engineering gave M20B25 the name 'verschieden', meaning 'different' in German. The engine is often referred to as 'the differing one' due to the anomalous valve system. With a minor modification that adjusts the idle speed of a cold engine, the 325i fulfills Euro 2 emission requirements in Germany, resulting in a lower tax compared to Euro 1 (as of 2005).
