Ignition system requirements

In Simple Terms

Each cylinder in an F1 engine must have exactly one ignition coil and one spark plug to fire once per engine cycle. This standardized system prevents teams from using multiple sparks or unconventional ignition methods that could provide unfair performance advantages.

• One ignition coil per cylinder maximum
• One spark plug per cylinder maximum
• Only one spark permitted per cylinder per engine cycle
• Prevents advanced ignition systems that could enhance performance unfairly
