1994 BMW M3 Coupe from UK and Ireland - Comments

McLaren commissioned BMW to design a engine capable of 600bhp. BMW took the blue print of the M3 block, adjusted it, and gave it to McLaren. With the M3 you're getting great performance for what you're paying.

To the person who left the comment on the 15th May:

If you had read the above post by someone who clearly understands engines, you should have known you were out of your league.

1. It is not uncommon to make a v engine by welding two in-line engines. All you do is put each block at an angle and then share the crankshaft.

2. A boxer engine is not two banks sat upright next to each other; rather the cylinders are on their side, and are opposite each other (with the camshaft in the middle). It means that almost literally, the pistons 'box' each other, and is what gives Subarus that distinctive engine note. (Called a flat four engine)

As the engine sits flat, rather than upwards, the idea is it gives the engine a lower centre of gravity.

Iv had my 94 m3 3litre for 1 year now and the thing is excellent! I have owned plenty of turbo, d cars and the whole package with the m3 coupe is brilliant in regards to comfort style and performance.

I do however admit depending on how you drive these machines, they love to eat tyres full stop! petrol consumption is a pain, but who cares! out of 10 I rate them @ 8/10.

And less electric gizmo, s on the car unlike its evo brother!

The McLaren V12 is indeed based on two 3.0l e36 M3 S50B30 engines, not the 3.2, hence why the displacement is 6.1l not 6.4. The 3.0 is obviously more reliable than the 3.2 from the evo because of the single vanos rather than double. The F1's v12, also shares the single vanos.

What a load of bullplop!

2 m3 engines welded together!!! haha that's funny.

Why would bmw spend millions developing the engine in such a way, it would be no where near as reliable as taking a standard already proven engine and modifying it.

The engine in the f1 is basically a heavily modified s70 from the 7 and 8 series range and was used in the mate concept to begin with followed by a much more powerful version in the road going f1.

Bmw took there own standard v12 and made it better. no need to mess about welding two engines together. lol.

BTW, to the 20th nov, 5:30 commentor the above poster is correct in what he says.

Engine capacity is measured in cylinder volume and stroke, either cc ot ci, but you already knew that.

Even if the engine was 2 engines welded together like you state then the capacity would still be the same, as that is not being changed on either the head or block.

I can see your logic behind it, however in engineering the science is worked out by cylinder volume (bore) and also the stroke of the engine to create the engine output.

That's why if somebody says they have bored out or stroked the engine this is what they are referring to they have increased the engine capacity by increasing the amount of combustion in the engine cylinders.

Lesson over.
