2006 Technical Regulations
2006 mandated 2.4-litre V8 engines, ending the V10 era that had begun in 2000. All manufacturers had to develop new V8 architectures from scratch — a reset engineered to slow engine-development arms races. Tyre changes during the race were restored (reversing the 2005 rule). Grooved dry tyres continued. The three-part knockout qualifying format (Q1/Q2/Q3) was introduced and has remained the F1 qualifying format since. Fernando Alonso defended his title with Renault; Michael Schumacher retired (for the first time) at year-end.
V8 2.4L era begins
2.4-litre naturally-aspirated V8 became the mandatory engine configuration. Peak power dropped by roughly 20% vs the V10 but manufacturers quickly recovered through revs and efficiency. V8s defined the competitive landscape until the turbo-hybrid reset of 2014.
Key changes
- V8 2.4L mandatory (replacing V10 3.0L).
Knockout qualifying (Q1/Q2/Q3)
Single-lap qualifying was replaced by a three-part knockout session. Q1 eliminated the slowest five to ten cars, Q2 eliminated another five, Q3 ran among the remaining ten to set the top of the grid. The format was an instant success with teams, drivers and fans and has remained in place with only minor adjustments since 2006.
Key changes
- Three-part knockout qualifying (Q1/Q2/Q3) introduced.
