World Motor Sport Council met in Monaco on 7 December, 2007 and the following decision was taken (from FIA World Motor Sport Council press release): As part of the total 10-year freeze on engine development, only engines which have been homologated by the FIA and delivered no later than 31 March 2008* may be used at an Event during the 2008-2017 Championships. Any such engine must include all the parts described in the 2008 F1 Technical Regulations and be identical to one which has completed two race Events during the 2007 Championship season.
* Or at the first opportunity in the event that a competitor has no engine available which has completed two race Events in the 2008 Championship season.
The 10 year ban on engine development was accompanied by the following aerodynamic testing restrictions:
• Teams to use no more than one wind tunnel.
• Test fluid to be air at atmospheric pressure.
• Maximum test section wind speed 50m/sec.
• Maximum model scale 60%.
• No more than one model to be tested during a run.
• Maximum usage to be equivalent to 15 runs per 8 hour day on 5 days per week for team F1 purposes. Tunnel may be contracted out at other times.
• Aerodynamic testing may only take place in wind tunnels if at reduced scale or at FIA approved test tracks if full scale. Full size testing to be subject to the F1 testing agreement.
• Full scale specific aerodynamic testing is to be reduced to 5 days/year.
• Restrictions will be imposed to stop shift of resource from wind tunnel testing to CFD.
• The number of people involved in CFD
development will be limited to a number to be agreed.
• CFD computer systems will be characterised in order to set hardware performance limits but growth will be allowed year-on-year to allow for hardware / software development.
