As above. Bernie claims that the only team/company who doesn't want the rules changed is Mercedes/Daimler. I'm sure they have signed the concorde agreement so the team can't suddenly pack up and leave... So lets say F1 engines are simplified. 2.5 V10 with direct injection, capped at 19000 RPM, 8 units a year, cost capped at say 300k per engine. Add in a bolt on (K)ERS system, with a large battery so that like now, more power can be used for a longer period of time. We know there are several KERS manufacturers, several independent engine shops who could be interested in (a return to) F1 (Cosworth for example). Renault is still interested in F1, since they're looking to buy a team. They would do anything for a new engine formula. Honda not having much success either and would they really pack up after a season? I highly doubt it. We know Ferrari is game. If Mercedes stick to their guns and don't want to participate with a new engine, then that means no V10 from Mercedes. I'm pretty damn sure they can't just let their team sit there due to the concorde agreement...hell, it would be a pretty good buy for Honda or Renault if they're selling! Sticking to the no Merc V10 engine, that leaves a bunch of teams (Williams, Force India, Lotus, Mercedes) without an engine...Renault/Honda (and Cosworth, if they would return) could recoup a sizable investment by selling engines to new teams. ------- So would it be so bad if Mercedes ''leaves''? I think not. Only a tiny percentage of F1 fans like the current engine formula. Stick them on a race track, let a V10 drive past, then a GP2 car, then a current car...their opinion will change for almost all of them.
