Detailed Analysis: The BMW B58 Inline 6-Cylinder Engine

The upcoming 2016 BMW 340i will be equipped with a 3.0L turbocharged I6 engine (code name: B58).

Along with the face-lifted 2016 3 series, BMW has also released one image of the new-designed B58 6 cylinder turbocharged engine, which is used on the upcoming 340i (replacing the 335i).

1. It is using a single turbocharger, a similar design as the current N55 engine; the turbocharger will be a twin-scroll type;

BMW Will Roll Out the New Engine, July 2016

In our previous article we reported that BMW will make some changes to the 3/4-series. BMW will rename the 35i models to 40i, and also the 28i will become 30i.

This is not JUST a name change because the current N55 6-cylinder engine in the 35i models will be replaced by the newly-designed B58 engine.  The same for the N20 engines in the 28i trims: it will be replaced by the brand-new B48 4-cylinder engine as well. BMW is going to roll out this engine swap starting July 2016 and we can NOT wait.
