More info here:

http://www.ilmor.co.uk/concept_5-stroke_1.php

That's confused me.  I thought they had become Mercedes and were powering the Brawns, Maclarens etc.

Ilmor have been making and doing most of the Merc engine design work for years......just dont tell the germans  ;D ;D

With the middle cylinder being double the size as the outer  two I would say its got the power of a V8 in a V6, there fore having less weight but more power, and its still 4 stroke.

Add a small injector to the centre cylinder and you have a 5 stroke with a 2 stroke booster stage.

1 and 3 fire 360 degrees crank rotation apart, so on alternate rotations. This is why they are in the same position on the crank, but their cam lobes are 180 degrees out.

Just like cylinders 1 and 4 on a GM V6 or 1 & 4 / 2 & 3 on a 4 pot.

I wonder how well balanced this engine would be?  :-/

I was right :y

Also it will be balanced if 2 weighs the same as 1 & 3 together.

Laverda have done 180 degree triples, but 120 is normally better.
