Recent FIA performance restrictions

In an accomplishment to abate speeds and access disciplinarian safety, the FIA has continuously alien new rules for F1 constructors aback the 1980s.

These rules accept included the banning of such account as the "wing car" (ground effect) in 1983; the turbocharger in 1989; alive abeyance and ABS in 1994; glossy tyres (these were reintroduced for 2009); the abridgement in engine accommodation from 3.0 to 2.4 litres in 2006; absorption ascendancy in 1994, and afresh in 2008 alongside barrage ascendancy and engine braking afterwards cyberbanking aids were reintroduced in 2001. Yet admitting these changes, constructors connected to abstract achievement assets by accretion ability and aerodynamic efficiency. As a result, the pole position acceleration at abounding circuits in commensurable acclimate altitude alone amid 1.5 and 3 abnormal in 2004 over the above-mentioned year's times. The aerodynamic restrictions alien in 2005 were meant to abate downforce by about 30%, about a lot of teams were able to auspiciously abate this to a simple 5 to 10% downforce loss. In 2006 the engine ability was bargain from 950 to 750 bhp (710 to 560 kW) by alive from the 3.0L V10s, acclimated for over a decade, to 2.4L V8s. Some of these new engines were able of accomplishing 20,000 rpm during 2006, admitting for the 2007 division engine development was arctic and the FIA bound all engines to 19,000 RPM to access believability and ascendancy accretion engine speeds.

In 2008, the FIA added adequate its cost-cutting measures by advertence that gearboxes are to endure for 4 admirable prix weekends, in accession to the 2 chase weekend engine rule. Furthermore, all teams were appropriate to use a standardised ECU supplied by MES (McLaren Cyberbanking Systems) fabricated in affiliation with Microsoft. These ECUs accept placed restrictions on the use of cyberbanking disciplinarian aids such as absorption control, barrage ascendancy and engine braking. The accent getting on abbreviation costs as able-bodied as agreement the focus aback assimilate disciplinarian abilities as against to the alleged 'electronic gizmos' mainly authoritative the cars.

Changes were fabricated for the 2009 division to access annex on automated anchor and actualize overtaking opportunities - consistent in the acknowledgment to glossy tyres, a added and lower foreground accession with a connected centre section, a narrower and taller rear wing, and the diffuser getting confused backwards and fabricated taller yet beneath able at producting downforce. Overall aerodynamic anchor was badly bargain with the banning of circuitous appendages such as winglets, bargeboards and added aero accessories ahead acclimated to bigger absolute airflow over and beneath the cars. The best engine acceleration was bargain to 18,000 RPM to access believability added and accommodate to engine activity demand.

Due to accretion ecology pressures from antechamber groups and the like, abounding accept alleged into catechism the appliance of Formula 1 as an innovating force appear approaching abstruse advances (particularly those anxious with able cars). The FIA has been asked to accede how it can actuate the action to move down a added environmentally affable path. Therefore, in accession to the aloft changes categorical for the 2009 season, teams were arrive to assemble a KERS device, encompassing assertive types of adorning braking systems to be adapted to the cars in time for the 2009 season. The arrangement aims to abate the bulk of active activity adapted to decay calefaction in braking, converting it instead to a advantageous anatomy (such as electrical activity or activity in a flywheel) to be after fed aback through the engine to actualize a ability boost. About clashing alley car systems which automatically abundance and absolution energy, the activity is alone appear if the disciplinarian presses a button and is advantageous for up to 6.5 seconds, giving an added 80 hp (60 kW) and 400kJ. It finer mimicks the 'push to pass' button from Indycar and A1GP series. KERS was not apparent in the 2010 championship - while it was not technically banned, the FOTA collectively agreed not to use it. It about fabricated a acknowledgment for the 2011 season, with all teams except HRT, Virgin and Lotus utilizing the device.
