Formula 1 Renault R23B from 2003, V10, 600 kg.
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 chassis was designed by Mike Gascoyne, Bob Bell, Tim Densham and John Iley with Pat Symonds overseeing the design and production of the car as executive director of Engineering and Jean-Jacques His leading the engine design.
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.
