BMW’s marketing machine is a keen unit that knows how the world goes round. The people are specialists, and they surely have an idea of how to attract people not only to test the products they are selling but also to buy them.
In this endeavor to break sales record after sales record and bring in as much cash as possible, you’re bound to make some mistakes. Apparently, the trademarked ‘TwinPower Turbo’ name is one of those mistakes.

According to, BMW USA has a class-action lawsuit going against it at the moment, claiming that the name is confusing and tricking people into buying the plants.

The plaintiff claims that the ‘TwinPower Turbo’ phrase has been designed specifically to trick people into believing they have twin-turbo engines under the bonnet whereas, in reality, that’s not the case. The whole thing is just a big misunderstanding if you ask us.

First of all, the complaint is based on 2007 to 2009 power plants that indeed used two turbochargers for the same engine. That was the case only for the N54 units though, not all of them. Those inline 6-cylinder 3-liter plants had two single scroll turbos that worked in tandem.

However, that platform had some engineering issues that led to overheating most of the time. Therefore, starting with 2009, BMW introduced the N55 plant that was an upgrade. What this unit had was a single turbo with twin-scrolls. It delivered the same performance without the overheating issue.

I can see how it might be confusing at first, but just the smallest Google search will enlighten you in a matter of minutes. We even wrote a full guide explaining what’s new inside the TwinPower turbo engines.

What people need to understand first and foremost is that the phrase is used to describe a host of technologies, not just the turbos used. TwinPower Turbo describes the combination of a turbocharger, double-Vanos technology and direct injection, all of them contributing to better fuel consumption and performance.

That’s also why the plaintiffs have a case because BMW used the same term for both the twin-turbo setups without VANOS and the newer ones with one turbo and VANOS included.

The lawsuit was apparently filed on behalf of all current, and former owners and lessees of BMWs fitted with the N55 engine by Deepkarn Bedi in the United States District Court for the District of New Jersey.
