2004 Technical Regulations
2004 enforced a strict one-engine-per-race-weekend rule: a single V10 had to complete Friday practice, qualifying and the race. Exceeding this triggered a 10-place grid penalty. The rule pushed engine manufacturers to find reliability margin at 19,000+ rpm without sacrificing power. Ferrari's F2004 was arguably even more dominant than 2002's F2002 — 15 wins from 18 races and both titles. No foundational chassis or tyre rewrite.

One engine per weekend
A single power unit had to last the full Friday-to-Sunday weekend. The rule evolved over the following seasons — two weekends per engine in 2005, then longer pools — culminating in the strict seasonal allocations of the V8 era. Grid penalties for engine changes became a fixture of strategic decision-making.
Key changes
- One engine per race weekend; 10-place grid penalty if changed.
