BMW says new 3-cylinder engine might not make it to next 3-Series [video]

The new 1.5 liter 3-cylinder power plant will feature Twin Power turbocharging and be good for an output of around 110 kW / 150 PS

A recent BMW CGI presentation revealed how the brand's upcoming 3-cylinder engine is basically devised from splitting an inline 6-pot in two, which you can see in the CGI animation video posted above.

That upcoming engine will feature Twin Power turbocharging technology which should make the 1.5 liter unit good for around 110 kW / 150 PS - a proper fit for an entry-level variant of the upcoming 2012 3-Series.

But the video shows the power plant being mounted transversely into an engine bay and BMW sources have told Autocar that there are issues involved in fitting that new 3-cylinder engine into the next 3-Series.

BMW customers may balk at what has always been an longitudinally-mounted engine in a rear-wheel drive 3-Series. BMW also says there are costs involved in making the modifications required to mount the 3-cylinder transversely in the next 3er.

BMW may simply opt to use the engine on MINI models as well as on its upcoming lineup of front-drive vehicles including models such as the i3.

I love this future for BMW. If only for the anguish that it causes the pimply faced teenage masses that post on WCF.

Yap I totally agree with you benz_man. There are so many issues with a Tranversely mounted FWD, such as: 1. Torque Steer issues 2. Drive Shaft (wear and tear and precision driving issues) If I can just get my hands on the Jerk who came up with this stupid idea? BMW has been the Ultimate Driving Machine all these years because of one thing and one thing only and that is because of their Longditudinally mounted RWD configuration. It is your most valuable Trade Mark...dont loose it BMW.

Such a chore to mount it longitudinally? Caterham seens to have no problem taking traditional front wheel drive engines and mounting them north south with drive channeled to the rear, so I can't see it defeating the boffins in Munich.

kinda weird to pop the hood of a BMW and see a transversely mounted engine. it will be interesting to see if they can make it with their famous 50/50 weight distribution with that layout in a future 3'er

Correction: the i3 is not FWD. It will have a MR layout according to Autoblog. Anyways 150HP is a bit anemic for a 3000lb car, but that 3-cyl turbo diesel would be awesome in the city cars, minis or any of the new hybrid lineup!
