Talk:BMW N55

It should be clarified that there is a clear difference in the brand naming for BMW turbo engines.

N54= "Twin Turbo" = 2 turbos of the same size with single-scroll tech, feeded by 3 cyliners each

N55= "TwinPower Turbo" = 1 turbo with twin-scroll tech.

M57 Diesel (335d/535d) = "Variable Twin Turbo" = 2 turbos of different size (small and big one), feeded by all cylinders, working together or alone based on current RPMs

Sticking to verifiable claims
This edit (and subsequent very similar edits by Touranushertz) contain a significant number of claims which aren't, in my opinion, supported by WP:verifiable references. Therefore I have trimmed it back to content supported by the references. 1292simon (talk) 09:29, 5 October 2012 (UTC)

Picture for infobox would be great
Hi. This article briefly had a picture of the engine in the infobox. Alas, the image violated copyright so it was removed. If anyone has a picture of the engine to share, that would be great. 1292simon (talk) 07:51, 19 November 2012 (UTC)

Weight
Why are there no weights listed? Surely a page about engines should include their weights. It's a very significant aspect of engine design. — Preceding unsigned comment added by 94.175.102.211 (talk) 10:20, 12 June 2021 (UTC)
