The E46 3 series has a 320i model with the familiar 2.2 in-line 6 engine developing 170bhp. This engine is also available in the E60 520i.However, this engine has been phased out for the new E90 3 series. The E90 320i would use the present E46 318i's 2.0 4 cylinder engine with power bumped up slightly to 150bhp (the E90 318i would be a 129bhp 1.8 4 cylinder).Does it therefore mean that the 2.2 6 cylinder engine would also be phased out for the E60? Worse still, does it mean that thereafter the E60 520i would only have a 2.0 4 cylinder 150bhp engine? I think the 2.0 4 cylinder 150bhp engine is no match for the 2.2 6 cylinder 170bhp engine.
