2006 F1 Regulations
V8 Era Begins
The V10 era ended after a decade. The FIA mandated a switch to 2.4L V8s with a 19,000 RPM rev limit, shedding around 200 hp overnight. It was a cost-cutting measure above all. V10 development spending had spiraled out of control, with top teams running entirely new engine specs almost every race. The 2005 US Grand Prix tire farce, where only six Bridgestone-shod cars started after Michelin couldn't guarantee tire safety through Turn 13, accelerated the move toward a single tire supplier (Bridgestone from 2007). The knockout qualifying format (Q1, Q2, Q3) also debuted and has remained essentially unchanged since.

Impact on Racing
- Despite losing 200 hp, the V8s still revved to nearly 20,000 RPM and sounded spectacular: many fans consider them the last great-sounding F1 engine
- The Q1/Q2/Q3 knockout format was an instant success and is still the basis of qualifying 20 years later
- Renault won the final V10 title (Alonso, 2005) and the first V8 title (Alonso, 2006), bridging both eras
- The engine life limits introduced in 2005 carried into the V8 era, an early preview of the component pooling that dominates the hybrid era
- The tire war's end removed a variable that had defined grid performance for years: no more Michelin vs Bridgestone track suitability swings
