Formula 1 technical tweaks aim to boost overtaking ahead of 2021 overhaul

Formula 1 technical director Ross Brawn said simulation work shows that modest aerodynamic changes introduced for the 2019 season – including revised brake ducts, rear wings, bargeboards and front‑wing details – are producing “tangible” gains in overtaking potential. He noted that while the full impact will be judged at the Australian Grand Prix, the adjustments are a first step toward a larger regulatory overhaul planned for 2021.

The new technical package also reshapes betting markets, as Canadian sportsbooks advise punters to watch practice pace, grid penalties, weather and the evolving power‑unit rules that will stay in effect through 2026. Reliability, energy management and development speed are highlighted as key factors that could shift odds throughout the season.
