The FIA (well, Max Mosley actually) is hell bent on restricting F1 engine development. This whole idea of engine homologation means that the championship entrants will have submit an engine to the FIA, which the FIA will certify. After this the team/supplier will not be allowed to modify the engine (basically make improvements in performance to it) for a whopping 3 years!!! I couldn't believe it when I first read it. The whole idea is to reduce costs. While it will definitely reduce costs it takes a big chunk out of the technical pinnacle that F1 really is. I mean, this thing is extreme. I could understand a 6 month to a 1 year freeze. That would also reduce costs, but this is taking it too far. I mean, they could just as well have asked them to use existing road car parts. While it would still be F1 and still be motor racing, but that not at all exciting in anyway.
F1 is supposed to be unique, not something that is ChampCar pretending to be unique. I totally support restrictions on design modifications for the running season, but not something that restricts design across seasons.
