Engine supply

I was reading on a rival website about the likely distribution of engines next year. Obviously the manufacturers: Ferrari, Renault, Toyota, Mercedes, BMW and Honda will use their own engines, but there seems to be the possibility of change for many of the more independent teams.

Williams (Cosworth) change to Toyota/Lexus
MF1 (Toyota) change to Cosworth (assuming Toyota don't want to supply more than one other team)
Red Bull (Ferrari) change to Cosworth V8
Squadra Toro Rosso (Cosworth V10) change to Ferrari

which just leaves Aguri remaining with Honda, no surprise as they are the Honda B team after all.

Now this isn't a real issue, but given that changing engine supplier means a lot of change - it affects weight distribution, cooling characteristics, gearbox design etc: it's easy to see that a significant cost is involved.

And bearing in mind that it's the independent teams that are all changing engines, for one reason or another, it sort of makes a mockery about the insistence of Max Mosley that costs must come down. Just a thought.
