Avg DNFs per race (stacked by cause)
In the 1950s, mechanical failures accounted for 38% of all DNFs. By the 2020s that had fallen to 13% — as modern materials, electronics, and manufacturing processes transformed reliability.
Collision retirements were proportionally highest in the 2020s (72% of DNFs). The post-1994 safety overhaul, FIA sporting regulations, and modern tyre compounds have progressively reduced incident-related retirements.
Average DNFs per race have fallen from 11.0 in the 1950s to 2.8 today — a 80% reduction. In 1950s Formula 1, a car completing a full race distance was the exception, not the rule. Modern F1 has inverted that reality entirely.

A DNF (Did Not Finish) is recorded whenever a driver fails to complete the full race distance. Retirement reasons range from catastrophic engine failures to multi-car collisions, tyre blowouts, and electronic gremlins. The Ergast / FIA data classifies each retirement by a specific status string — we group these into broader categories for analysis.
Mechanical failures dominated the early decades of Formula 1 when cars were far less reliable. Engines, gearboxes, and suspension failures caused the majority of retirements throughout the 1950s–1980s. The introduction of FISA safety regulations and advanced manufacturing techniques gradually improved reliability.
Collision-related retirements peaked in the late 1980s and early 1990s before stricter rules about racing conduct were introduced. Modern F1 still sees on-track incidents, but the frequency has declined significantly.
Power unit and electrical failures became more common after the introduction of the V6 turbo-hybrid regulations in 2014. The complex Energy Recovery Systems (ERS), MGU-H, and MGU-K components introduced new failure modes, though manufacturers have dramatically improved reliability year-on-year.
