The year 2020 is creeping closer and car makers are struggling to meet the new CO2 emission standards set for Europe. Some such  as Volkswagen are already well underway to meet that deadline.

And while all car makers agree that the environment is important and do want to help protect it, some think that the new standards are too high to meet.

BMW is part of this camp, considering the target set for 2020 is impossible to reach. This target refers to an overall 30% decrease in CO2 emissions, and BMW considers that this standard is just a political promise that was made with insufficient data considering technology evolution.

For BMW to reach the levels of CO2 expected by 2020, huge amounts of money would have to be poured into technology research and development. And it’s not like the German car maker isn’t trying to go greener. There are a lot of projects funded by BMW to further this very end, like hydrogen collection, alternatives for EV charging and so on.

After they have announced their frustration at the CO2 emission targets and the sacrifices they will have to make in order to meet them, BMW is now dropping the naturally aspirated engines. And it seems the culprit is the same Euro6 regulations considering CO2 emissions.

The first one to go will be the BMW 5 Series, which come summer and the facelifted version, it will be powered by an N20 4 cylinder engine instead of the N53B30 in line six. That might be a bitter pill to swallow for many community members, but the BMW 535i just didn’t comply with Euro 6 regulations.

And the 5 series is not the only model to drop naturally aspired engines. Once the 2 Series launches and replaces the 1 Series Coupe and Convertible, it will also sport a cleaner 4 cylinder engine, dropping the N52. Even the BMW M3 will lose its naturally aspirated engine, but since the current generation vehicles are all spoken for, you can consider it already gone.
