The Ferrari F2004 is a highly successful Formula One racing car that was used by Scuderia Ferrari for the 2004 Formula One season. The chassis was designed by Rory Byrne, Ignazio Lunetta, Aldo Costa, Marco Fainello, John Iley, and James Allison, with Ross Brawn playing a vital role in leading the production of the car as the team's Technical Director, and Paolo Martinelli assisted by Giles Simon (engine design and development) and Mattia Binotto (engine operations). Heavily based on the previous season's F2003-GA, the F2004 continued the run of success the team had enjoyed since the 1999 Formula One season, winning the team's sixth straight Constructors' Championship and fifth straight Drivers' Championship for Michael Schumacher, his seventh and final world drivers' title in 2004. The 50th Formula One car built by Ferrari, it is one of the most dominant cars in the history of Formula One.
