F1's 'Energy Starvation' Problem

Why it matters

The 2026 power units increase electrical power to 50% of total output, but current designs leave cars vulnerable to massive speed drops on straights as batteries deplete. Williams Racing has presented four or five proposals to the FIA to address the energy starvation problem. Aerodynamic changes exacerbate the issue; less drag means less energy regeneration through braking. Active aero, intended to boost straight-line speed, may not fully compensate for regen losses. Teams anticipate needing to lift and coast for hundreds of meters before corners to recharge batteries, a major shift in driving style. This lift-and-coast issue is predicted to create unnatural racing and passing opportunities.

Key numbers

• The 2026 F1 season opener exposed 'energy starvation' due to new hybrid power unit regulations and drag-reducing aero rules.
• The 2026 power units increase electrical power to 50% of total output, but current designs leave cars vulnerable to massive speed drops on straights as batteries deplete.

What happens next

• Active aero, intended to boost straight-line speed, may not fully compensate for regen losses.
