However, the reality is seen after the race and the unit has to be changed out. Lotus and Ferrari are on the cusp and I wouldn't be surprised if in a couple gp they are next to get penalized.
All of the Ferraris are on their third batteries. Räikkönen is also on his third generator unit.
So far, I have felt that most of the criticisms of the new engine formula are without merit. The sound is quieter, but there is a lot more texture; you can hear the engine, the turbo, the ERS, the wheelspin and even the car glancing the kerbs. The tail-enders are slower than GP2, but the GP2/11 chassis won't be developed any further.
But if there is one criticism that is valid - and it hasn't really been voiced yet - it's that the part restrictions are too tight, and the penalties too severe. I understand and fully support the way they are intended to cut costs and promote reliability, but I think it would have been better to wait a year for everyone to get their head around it first. As it is, I think there is a real risk of qualifying becoming a pointless exercise as people incur grid penalties. It's a problem that will naturally correct itself with time, but until then, something else it needed. I have a few ideas for temporary solutions, but I don't think they would be too popular:
1) Lose a set of fresh tyres. If, at any point, you go over the allocation of parts, the team has to return a set of fresh tyres.
2) Fastest qualifying time is disallowed. A driver's grid position will be decided by his second-fastest qualifying time; alternatively, by his fastest time on the slower tyre. If a part is changed after qualifying, the grid is simply rearranged.
3) A "penalty box" in pit lane, where the driver is forced to drive a longer distance (where available), or have their speed restricted from 80km/h to 60km/h.
Of course, I think grid penalties for going over quota are important, but I think there is a risk that grid - and even race results - will be decided by penalties, not times.
