The 320si is a limited-production sedan built for European markets and homologated to support BMW's involvement in the World Touring Car Championship, using a bespoke 2.0-litre naturally aspirated inline-four producing 173 hp rather than the inline-six found in most of the range. Torque is a modest 200 Nm and the 0 to 100 km/h sprint takes 8.1 seconds, but the engine's high-revving character and motorsport origins give it a distinct identity within the E90 lineup.
