how do you figure that out when even the teams have not got their hands on the engine yet?
As for no limitations on development they still have to work to the same rules.
Yes we all know Cosworth have built a lot of F1 engines but they have not built any in the last few years and the engines have moved on a lot since the last time they powered an F1 car.
Would you care to elaborate on the changes in the last few years that is of such a revolutionary art that Cosworth, with the aid of at least 4 of their former engineers that they have gotten back from Mercedes, isn't going to understand?
Yes, they have to work to the same rules, which lays down a few basic guidelines and limits. The rest of the engines are having to deal with those regulations with a engine from 2006, designed for other limits. Cosworth, while using their 2006 engine as a basis, can make fundamental modifications and changes to that engine that the others cannot (Cosworth can do this as they are considered a new engine supplier). This means that Cosworth has the potential to avoid some of the compromises the others have to deal with. And on top of that the 2006 Cosworth was considered the best engine of the season, so even without the modifications they are allowed to do, Cosworth would arguably have the best base engine for the current rules.
