Maybe so, but it would be mean more unnecessary work for the other teams just because Renault cant build an engine as powerful as the others. Why should Brawn, FI, Mclaren, and Ferrari spend money trying to intergrate a restrictor in the car design to not be too detrimental to overal performance when its Renault and Toyota with the problems.
Like I said I am all for allowing Renault and Toyota making adjustments to their engines because to me, though maybe more expensive (maybe not) it will be more simple, and will not hinder the performance of the other cars.
For all we know, alot of this could be down to Renault and Toyota building cars which suffer from more drag than the others. This is Renaults/Toyotas problem, no need to make it everybody elses.
Besides that for two years now, Renault have complained. How well is it going down in the board room that Mercedes next door are having to de-tune their engine so the Frenchies can catch up? I dont suppose it went down well at Honda last year either! The company was all about engines then went to having the worst car, and engine on the grid!
