F1 » Spanish Grand Prix 2013: New hard tyre won't change much – Vettel


A forced induction engine is more efficient than an NA engine. Size being equal, a forced induction engine will be able to use more fuel for the simple reason that a much bigger mass of air will be forced into the cylinders. The fuel/air ratio will still stand at one part of fuel to every fourteen point seven parts of air. A forced induction engine will run a lower compression ratio. And finally, the pure petrol head will only see the real challenge of the ability of extracting the maximum power from an engine design when the design is NA.

F1 » Spanish Grand Prix 2013: New hard tyre won't change much – Vettel


The stoichiometric ratio is the perfect ideal ratio, it is a technical term used to express a perfect combustion were no left over’s are left, unburned air or fuel. The problem in real life is, there is and will never be anything mechanical which can be said to be one hundred percent perfect. The 1.6l v6 turbo will have a lot more torque at much lower engine rpm. The 1.6l v6 turbo engine running at max 15k rpm will consume less fuel than the 2.4l v8 running at max 18k rpm, even if the combustion is of the same size and efficiency there will be less combustions per minute.

F1 » F1 2013 driver salaries published – but who earns most?


Ben, Richard was quoting Berger, before one disagrees with a man the calibre of Berger one has to take into consideration his direct experience. Richard like most experienced posters on this forum can calculate with easy the difference between Berger’s experience and that of an unknown poster following the sports and most probably blinded by his support to a driver. I for one fully understand your opinion as to what the experienced Berger said.

F1 » Hill: Tyre change to favour Red Bull?


All teams except Mercedes out to benefit from Pirelli’s changes to the hard tyre, of course only when the hard tyre is being used. It is imperative to keep in mind that overheating a tyre is as bad as not being able to get the tyre into its working temperature range, a car which overheats its tyres in a short time will be capable to set a fast time over one or two laps. Regardless of the technicalities Hill spoke or was quoted about the tyres “being harder”, what Pirelli did was it lowered the hard tyre minimum working temperature from 110 to 100 degrees so it is now closer to the 90 degree minimum working temperature of the medium tyre.

F1 » F1 Spain 2013: Hamilton seeks to close gap


According to Prof X “Disparity to other cars” mean lack of equality between cars. And “tyre wear has a lot more to do with car setup” this statement lays bare the level of understanding of race car preparation by a professional team such as Mercedes, it sort of implicates that Mercedes has been setting up their cars in such a way as to wear their tyres in the shortest possible time for the last three years, it is a waste of time arguing F1 technical racing matters where such mentality is ingrained.
