BMW B58 tagged posts

I am sure all consumers in the US know that, for the 35i trim of the 2015 BMW X5, they are still coming with the company’s famous N55 6-cylinder 3.0L turbo engine.

But perhaps unknown to most people, the N55 engine on the 2015 X5 sDrive35i and xDrive35i, is a different version that only exists in US-spec X5. In fact, even though they are named “3.0L” in all documents and advertisements, it does not mean an exact number of 3,000 cc. Specifically speaking, the N55 engines installed in all other BMW vehicles (except the 2015 X5 35i) have a displacement of 2,979 cc.

Starting from the 2015 model year, BMW is providing a special version of the N55 engine on 2015 X5 35i models,...

We get the latest news for the BMW F3x models. Starting from the 2016 model year, the current N20 4-cylinder turbo engine will be replaced by the newly designed B48 engine; and the award-wining N55 turbo-6, will be upgraded to the B58 engine.

Therefore, the current N20-equipped models (328i/428i) will be renamed 330i and 430i. The N55-equipped cars (335i/435i) will be designated as 340i/440i.

This is not just a name change, according to our insider source, those two engines will be at least 10% more powerful than their predecessors. More specifically, the 330i/430i will be around 270ps; the 340i/440i will be approx. 330-340ps (depends on options chosen).

Starting July next year (2015), BMW will put the new designed 4 cylinder turbon engine (code name B48) in its 320i sedan, to replace the old N20 engine; Also the new B58 six-cylinder engine will appear in the 335i too.

The B48 engine uses piezoelectric direct injection, valvetronic, Double VANOS...
