After both Lotus wings collapsed at the Spanish Grand Prix, the CSI banned wings from the Monaco Grand Prix practice, then allowed only wings fixed to the sprung bodywork, limited in height and width. Source
Overall height was limited to 90 cm above the ground, ending the tall engine air intakes; rear wing overhang cut to 80 cm. Source
The BT46B won the Swedish Grand Prix with a rear fan extracting air from under the car; Brabham withdrew it under pressure and movable aerodynamic devices were ruled out. Source
To curb ground effect, skirts touching the track were banned and cars had to clear the ground by 6 cm at rest. Teams answered with hydraulic suspension that lowered the car on track. Source
The underside between the wheels had to be flat, ending shaped ground-effect floors and skirts. Rear wings were moved forward and six-wheeled cars were banned. Source
Mid-race refuelling, used by Brabham in 1982–83, was banned and race fuel limited to 220 litres, starting the fuel-economy era of the turbo years. Source
Only 3.5-litre naturally aspirated engines were permitted, a formula that ran until 1994. Source
Active suspension, traction control, anti-lock brakes, launch control and fully automatic gearboxes were outlawed. Source
After Austria 2002, team orders that interfered with a race result were banned. The ban was lifted for 2011. Source
A common electronic control unit ended traction control, engine braking control and launch control; gearboxes had to last four races. Source
Track testing during the season was banned, with limited exceptions in later years. Source
Cars started with full race fuel for the first time since 1993; minimum weight rose to 620 kg. Source
The rear diffuser was restricted and driver-operated aerodynamic switching (the F-duct) outlawed; KERS returned. Source
Exhaust exits were fixed to positions that could not blow the diffuser; nose height was lowered, producing the stepped noses. Source
The point for fastest lap, reintroduced in 2019, was dropped. Source
