Follow the big engineering shifts that repeatedly reshaped Formula 1, from rear-engined cars and aerodynamic wings to ground effect, turbo power, carbon-fibre construction, hybrid systems and the 2026 reset.

By the end of the 1950s, successful rear-engined designs showed how moving major mass behind the driver could create a more effective racing package, and the front-engined layout quickly disappeared from Formula 1.
As Formula 1 engineers learned to use aerodynamic downforce, the shape of the car became as important as its engine output. Wings and increasingly sophisticated bodywork allowed cars to corner faster by pressing the tyres more firmly onto the track.
Lotus helped transform underfloor aerodynamics with ground effect in the late 1970s, while turbocharged engines became a defining performance route during the following decade. Both developments produced major gains and eventually prompted significant regulation changes.
