The Renault R25 was Renault's 2005 Formula 1 car, powered by a 3.0-litre V10 engine and driven to both world championships that year by Fernando Alonso. The 2005 season was the last for V10 engines in Formula 1 before the switch to V8 power in 2006, which is why this high-revving note is now associated with the end of a much-loved era. Clips of the car at full throttle have circulated for years among motorsport fans, who reuse them in tribute edits, historical comparisons and nostalgic racing content.
