I've been doing a spot of research on my next car. One of the options is a BMW 320i EfficientDynamics.
Despite the name, it's powered by a 1.6 litre turbo four-pot, and it makes 170ps. It's the same basic engine as an R56 MINI.

I've known about this for a few weeks, but the penny dropped for me on something this morning.

What it means is that all these cars share an engine:

Engines are very expensive to develop. OEMs share this cost.

I just never thought I'd see the day when a BMW 3-series was running about with an engine developed by Peugeot...

Yes, it's used all over the place.

and the point being?

the engine is just a form of power delivery,and as you are looking at the lower end, it isn't going to be bespoke.

the 2.7 v6 diesel was in jaguar and PSA cars.

I understand this of course - but of all the manufacturers, BMW is one of the last I'd expect to do this sort of thing (along with Honda and Ferrari).

Remember whilst they may have the same base engine, all the installation and transmission stuff will be unique. That includes Air Induction, Exhaust, Cooling, Fuel, Electrical, Mounts and HVAC.

That's something I noted on realoem.com while I was looking at something else. Arguably the biggest change to make the engine north-south for the 3er instead of the transverse installation it has in everything else is the placement of the oil filter. Other than that the base engine is, as far as I can tell, identical.

Obviously the rads and so on are different, to fit different shapes of car nose.

Plus the Volvo V50,Picasso,C4,Focus,most Peugeots inc.407s,fiesta etc.etc. BMW diesels are made by PSA and have been for quite a while now.

Rads are installation specific, as with all the components. You don't even necessarily use the same rad for one engine within the same company across all body-styles. In fact, we rarely ever do...

Which is one-upmanship speak for saying the BMW version will be better as a result. This sort of cheese-paring garbage is exactly what brand-conscious idiots cling to.

I've done work for both BMW and PSA, and I know which I'd prefer to be engineering my car.

Why Honda? They used to share almost everything with Rover & (certainly according to Wikipedia), some of the cars were even built at Longbridge.

If you've done work for both then by definition they should be the same, n'est-ce pas?

Or are you suggesting you were deliberately sloppy for one of them...?

You get to see how the companies in question behave. If you're asked the wrong questions by the wrong people in the wrong way and the comping mechanism for things going wrong is to ignore those things, it teaches you about how the company deals with things in general, from an engineering point of view. If you deal with a customer where you're asked the right questions by the right people in the right way, and when irrespective of whether things go right or wrong the company has processes to improve stuff, it teaches you about how the company deals with things in general, from an engineering point of view.

Honda because they are great at engineering engines, as with the other two companies.

The important bit is the engineering nous, for me. I couldn't give a damn if my 3er is built by BMW in Regensberg or Rosslyn, Magna Steyr in Austria or Valmet in Finland, because by the time you get to screwing the thing together you've already done the important bit of the engineering.

Likewise, I don't mind honda developing stuff other people screw together. If Honda started buying mainstream engines in from a 3rd party (I dunno, say from Toyota or GM), I'd be shocked. If the reverse were true I'd not be shocked at all.

I think the old PSA TU engine (that the prince engine is based on) seem's to be a more reliable engine.

It's also kind of weird to think if you look back in time, it all goes back to the 104

The prince was based on the TU which came out in 1986 in the AX, (powering the AX, Saxo, C2, C3, BX, ZX, Xsara, C15, Nemo, Berlingo, 106, 205, 206, 207, 309, 306, 307, 405, Bipper and Partner).

But the TU was based on the X engine (Douvrin) that came out in 72 in the 104 (powering the Citroën LN, Citroën Visa, Citroën BX, Peugeot 104, Peugeot 205, Talbot Samba and Renault 14.

So your new fancy bmw, mini, peugeot or citroen could be powered by something that owes its roots to this.
