Montezemolo having a moan again I see, blaming both the diffuser regulations and KERS for his teams' woes.
Well Red Bull have neither KERS nor the "trick" diffuser and are close to Brawn GP at the front of the field. Brawn themselves have no KERS.
Whilst he has, to some extent, accepted responsiblity by saying they were too complacent, it's this endless arrogance from Ferrari that fuels my hatred of them. They just can't accept that they're in a hole totally of their own making. Other teams have had to deal with the same regulations as they have and yet have done a far superior job. If they couldn't get their KERS working reliably, as McLaren seem to have managed, then they should have abandoned it prior to the season and introduced it later when they were happy with the reliability, as Williams are doing.
As for the diffuser, they may not have a "trick" one but then most other teams don't and are still doing fairly well and certainly better than they are. McLaren are also seriously lacking in downforce yet you don't hear them moaning about the regulations and claiming it's not their fault.
Ferrari have also moaned about how they're going to have to redesign their car significantly to factor in the new diffuser, well whose fault is that!? This suggests that, during the initial design phase, either the designers totally missed the "loophole" under which the "trick" diffusers are operating (in which case they're idiots) or (more likely) they did see it yet dismissed it out of hand without even considering that such designs could be proven legal (in which case they're arrogant and naive). Granted you can't totally hedge your bets and design a car which can accept both types of diffuser without compromising your overall design, so you have to "plump" for one design or the other but you'd think anyone with half a brain would realise there was a chance the loophole could be upheld and would thus ensure that, in such an event, the "trick" diffuser could be integrated into the car without starting from scratch. Ferrari obviously (IMO) looked at it and thought it would never, ever be proven legal and thus threw all their efforts into a design based around a conventional diffuser. ISTR that, in the run-up to the appeal court hearing, many were of the opinion that the FIA would rule in favour of the appellants simply because it couldn't possibly hand down a ruling which harmed its beloved Ferrari. Perhaps Ferrari themselves had the same thought back when they were designing their car?
