Close copy of championship-winning Mercedes W10 design
(+2)
The Racing Point RP20 was controversially similar to the 2019 Mercedes W10, particularly its brake ducts, leading to fines and point deductions. This incident sparked a major debate about 'copycat' cars and intellectual property in F1.
Innovative steering system
(+2)
Mercedes' innovative Dual-Axis Steering system allowed drivers to adjust front wheel toe angle, pushing the boundaries of technical interpretation. While legal for 2020, its subsequent ban highlighted the FIA's reactive approach to groundbreaking innovations.
Created immense downforce without increasing drag
(+4)
The Brabham BT46B, known as the 'Fan Car,' featured a large fan that generated immense ground effect, providing an unfair advantage. It won its only race before being immediately banned, becoming one of F1's most famous technical innovations.
The Williams team faced a significant fine for failing to provide required video files from their cars' cameras, a breach of a new technical directive. This incident underscores the ongoing scrutiny of bodywork flexibility and the importance of adhering to evolving technical regulations.
Allows for aerodynamic innovation and unique designs
(+2)
Flexible wings have been a persistent technical controversy, with teams exploiting design loopholes to gain aerodynamic advantages. The FIA's continuous efforts to implement tougher tests demonstrate the ongoing battle between innovation and regulation.

This major espionage scandal involved McLaren possessing confidential Ferrari technical data, leading to a record fine and disqualification. It remains one of F1's most significant technical and ethical controversies.
Deliberate crash to gain sporting advantage
(+2)
While primarily a sporting manipulation, the deliberate crash had significant technical implications regarding safety car deployment and pit stop strategies. It exposed a shocking level of team-ordered technical interference in race outcomes.
Exploited a loophole in the rules for more downforce
(+1)
The double-diffuser was a highly innovative aerodynamic design that exploited a loophole in the 2009 technical regulations, giving Brawn GP a significant performance advantage. Its legality was fiercely debated but ultimately upheld, leading to a championship win.
Generated massive power gains
(+2)
Ferrari's engine performance in 2019 raised suspicions of fuel flow manipulation, leading to a confidential settlement with the FIA. The lack of public explanation fueled widespread speculation and controversy regarding the legality of their power unit.
During the 1994 season, Benetton faced strong suspicions of using illegal traction control and launch control software. Although never definitively proven, the 'Option 13' controversy cast a shadow over Michael Schumacher's first championship.
BAR-Honda was found to have a hidden secondary fuel tank, allowing them to run underweight during races. This deliberate attempt to circumvent regulations resulted in disqualification and a two-race ban, highlighting a serious breach of technical rules.
Provided opportunity to produce additional downforce
(+3)
X-Wings were additional high-mounted wings designed to generate extra downforce, quickly adopted by several teams. They were eventually banned due to safety concerns and aesthetic reasons, marking a swift regulatory response to a novel technical solution.
