In the 2003 F1 season optional Friday testing at Grand Prix events was introduced in exchange for fewer miles on stand-alone test days. This was intended to give smaller teams a cheaper alternative to these test days, which were to be banned in 2004. Three constructors (Renault, Jordan and Minardi) entered free-practice-only drivers over the course of the 2003 season. Jordan entered for Friday practice Hungarian Zsolt Baumgartner (at German GP), Swede Björn Wirdheim (at USA GP) and Japanese Satoshi Motoyama (at Japanese GP). Wirdheim, fresh 2003 International Formula 3000 series winner, got the opportunity to test with Jordan. After turning down an offer to drive Champ Car, Wirdheim signed with Jaguar as third driver performing the Friday testing for the team at Formula One Grand Prix weekends during the 2004 season. He had no chance to prove himself in Grand Prix. Later Wirdheim raced in Champcars (in 2005), Formula Nippon (2006-2007), Japanese Super GT (2006-2019) with occasional appearances in FIA World Endurance Championship and European Le Mans Series, where he won the title in 2015.
