The BMW 3.0 Si was a variant of the BMW E3 New Six that was introduced in 1971. These sporty rear wheel drive sedans were powered by a fuel-injected, 3.0L version of BMW's M30 engine, which had an output of 197hp. This engine was available with manual or automatic transmissions. Interestingly enough, the 3.0 Si was actually quicker than its coupe equivalent, the 3.0 CSi, due to the lightweight nature of the sedans body in comparison to the bulkier coupe. In production until 1977, the BMW 3.0 Si left a legacy as one of the E3 New Six's most capable offerings.
