Renault R23

The Renault R23 is a Formula One car that competed in the 2003 Formula One season. The driver lineup were Jarno Trulli and Fernando Alonso who replaced Jenson Button who left for British American Racing.

The team started at pole at the 2003 Malaysian Grand Prix. Later the team 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 72 degree vee angle with the following year's R24.

Eventually the team finished fourth in the constructors' championship with 88 points.
