2017 F1 Regulations
Wider, Faster, More Aggressive
After years of complaints that the cars were too slow and too narrow, the FIA went the other way entirely. Cars grew 200 mm wider, Pirelli delivered fatter tires with significantly more mechanical grip, and the aero regulations gave teams far more freedom with the diffuser and rear wing. The result was the fastest generation of F1 cars ever: but the additional downforce was generated almost entirely by surfaces sensitive to turbulence, making the dirty air problem worse than it had ever been.

Impact on Racing
- All-time lap records fell at nearly every circuit: Vettel's 2017 pole at Singapore was 3 seconds faster than the 2016 pole
- The dirty air problem got worse, making close following harder and DRS-dependent overtakes the norm
- Wider front and rear tires gave drivers more confidence on initial turn-in but degradation management became more critical
- Teams immediately exploited the bodywork loopholes: shark fins and T-wings appeared within the first few races
- The speed was spectacular for qualifying but the racing product suffered, which directly motivated the 2022 ground-effect reset
