Page 1 of 1 After using an updated version of the 2002 MP4/17 for the first races of the 2003 season, the completely new MP4/18 was to make its debut halfway through the season. The MP4-18 incorporates a number of visible differences. These include a shorter and lower nose, a more tightly packaged rear and a slight dorsal fin shaping to the engine cover. Additionally the revised Mercedes-Benz engine, the FO 110P V10, has been lowered within the car, producing centre of gravity benefits. To improve overal performance the engine has been designed in close cooperation with McLaren.
The MP4/18 is the seventh car to appear in the distinctive West McLaren Mercedes livery, introduced at the 1997 Australian Grand Prix, which saw the first victory for the partnership. In the 106 Grands Prix since then, the team has secured 33 race wins, two Drivers' and one Constructors' World Championships.
The MP4/18 proved quick but far from reliable in testing. The MP4/17 proved very reliable and fairly competitive, which made McLaren decide to continue using the old car for the remainder of the season. Engine rule changes left the MP4/18 obsolete for the 2004 season, but many of the '18's' characteristic design elements can be found on the McLaren 2004 contender, the MP4/19. Page 1 of 1
