2019 Technical Regulations
2019 brought a targeted aero change aimed at making overtaking easier as a bridge towards the larger reset then planned for 2021. Front wings became wider and simpler (fewer stacked elements, no outwash-y-250 endplates), rear wings became taller and wider (larger DRS flap slot opening), and brake-duct winglet furniture was curtailed. 1.6-litre V6 turbo-hybrid PU architecture was unchanged. Pirelli allocation structure was simplified (five compounds named 'C1'-'C5' instead of the seven-colour system prior).
Aero — front/rear wing simplification
Front wings: wider than in 2018 with a simplified element count and less-aggressive endplate geometry. Rear wings: taller and wider, with a bigger DRS-open slot. Brake-duct furniture was cut back to reduce wake-shaping structures. The stated aim was to reduce the downforce lost when following another car. Real-world effect at the time was debated in the media — some follow-a-car improvement, but teams quickly recovered the lost downforce through development.
Fuel allocation & minimum weight
Race fuel allowance was lifted (widely reported as rising from 105 kg to 110 kg) to let drivers push harder without managing fuel consumption late in races. Minimum weight was also increased by a few kilos to account for driver + equipment combinations that were awkward under the prior figure, addressing a long-running complaint from heavier drivers.
Key changes
- Race fuel allowance raised.
- Minimum weight raised.
Power unit — component pool reduced
Per-season PU component pool was reduced in some positions vs 2018 (widely reported as 3 ICEs, 3 turbos, 3 MGU-Hs, 2 MGU-Ks, 2 ES, 2 CEs per driver per season, with grid penalties beyond). Developers continued to chase reliability and efficiency within the frozen architecture.
Specific PU pool-size numbers should be verified against the published Technical Regulations before quoting as fact.
