Despite outscoring his teammate during 2002, Button was dropped by Renault in . His replacement was Spain's Fernando Alonso, who had been considered impressive as a test driver the previous year. Alonso won the 2003 Hungarian Grand Prix, the first time Renault had won a Grand Prix since the 1983 Austrian Grand Prix. Renault was innovative during this period producing non-standard designs such as the 111° 10-cylinder engine for the 2003 RS23 which was designed to effectively lower the center of gravity of the engine and thus improve the car's handling. This eventually proved too unreliable and heavy, so Renault returned to a more conventional development route.
