So I will fill this with a long rant later about the conclusion of 2014 and what I expect from 2015 along with some items I've found about possible 2015 changes that could shake up the foundation that was laid in 2014... @MHPALA if you don't mind showing what you found now that I actually created the thread like you and others @GTPorsche had wanted. So yeah, let's have another great season of tech talk and changes in the teams as well. ENGINE RULES CHANGE 2015 OLD RULES BEFORE LOBBY Other than any parts solely associated with power unit installation in different types of car (which have no performance benefit and which may be changed from time to time during the homologation period with the consent of the FIA), any such power unit is one which is identical in every respect to either: a) A power unit delivered to the FIA no later than 28 February 2014. b) A power unit delivered to the FIA after 28 February 2014 which has been modified in accordance with the Annual F1 Power Unit Homologation table […] c) A power unit delivered to the FIA after 28 February 2014, or modified and re-delivered to the FIA after that date, which the FIA is satisfied, in its absolute discretion and after full consultation with all other suppliers of power units for the Championship, could fairly and equitably be allowed to compete with other homologated power units. […] 2015 FIA F1 Sporting Regulations, June 29th draft, Appendix 4, Article 1 (read the current rules in full – PDF link) NEW RULES/TOKEN CHART These are the items that can be changed this year during the course of the year but at the cost a certain amount of tokens, with each manufacture only being allowed (aside from Honda) 32 tokens. Honda at first were not going to be allowed any tokens and run under the same method of last years homologation after Feb 28th. however that changed. Now Honda are allowed tokens but in a different matter, the amount of Tokens Honda can have for the course of he season will be restricted to how many tokens remaining do the other manufactures have. After which it will be averaged and rounded down to the nearest whole number. So if Mercedes has 5 tokens, and Renault as 8 tokens and Ferrari has a 11 tokens, then the average between the three is 8 exactly and that would be the number of Tokens Honda can run. Token Chart Too lazy to make the chart based on the info provided myself, so I'll give a link to the one already made on F1fanatic that can be used to follow the changes through the year. http://www.f1fanatic.co.uk/2015/01/20/making-sense-f1s-engine-rules-2015/ TEAM RADIO RULES Under FIA technical directive TD/041 messages concerning the following are not permitted (either by radio or pit board) - Driving lines on the circuit. - Contact with kerbs. - Car set up parameters for specific corners. - Comparative or absolute sector time detail of another driver. - Speeds in corners compared to another driver. - Gear selection compared with another driver. - Gear selection in general. - Braking points. - Rate of braking compared to another driver. - Rate of braking or application of brakes in general. - Car stability under braking. - Throttle application compared to another driver. - Throttle application in general. - Use of DRS compared with another driver. - Use of any overtake button. - Driving technique in general.
