Here's how F1 is tweaking its hybrid systems to try to save the show
Summary
Formula 1 is changing its hybrid energy rules starting from the Miami Grand Prix to improve racing quality. These changes include limits on energy use per lap, more energy harvesting during acceleration, and new engine power rules in certain parts of the track to reduce speed differences between cars.Key Facts
- F1 cars have hybrid powertrains with powerful electric motors supported by batteries.
- Batteries can provide full electric power only for a few seconds each lap before power drops.
- Current rules allow using 8 megajoules (MJ) of energy per lap, but this will be reduced to 7 MJ from the Miami race.
- Cars can harvest more energy using “super clipping” at 350 kW instead of the previous 250 kW.
- The electric motor (MGU-K) can deliver its full 350 kW power in key acceleration zones like after corners and during overtakes.
- Outside these zones, the MGU-K power is limited to 250 kW to reduce big speed differences.
- Boost power when close behind another car is now limited to 150 kW extra.
- New safety rules will help detect and assist cars that struggle to start properly on the grid to avoid dangerous slowdowns.
