This small family, together with the N45 family, has taken the place of the previous N42 family, of which it retains the main construction features, namely:
4- cylinder in-line architecture ;
cylinder head with 4 valves per cylinder;
distribution with two overhead camshafts ;
presence of the Vanos double variable valve timing system ;
presence of the continuous valve timing system Valvetronic.
Few differences compared to the previous family, especially in terms of performance. Structurally, the main differences were in the better balancing and therefore in the reduction of vibrations by means of special balancing countershafts ; There were also new connecting rods, new roller tappets for the camshafts, new spark plugs and a new cylinder head. The two versions that make up the N46 family are described below.
