saw further changes, with the team again changing engine suppliers, this time to Hart. Again, the season started with two new drivers, Ivan Capelli and Brazilian rookie Rubens Barrichello. Capelli left after two races and Barrichello saw five other drivers become teammates of his during the 1993 campaign. Jordan only had moderate improvement, scoring three points. Signs of stability were beginning to show near the end of the season when Barrichello was joined by Eddie Irvine, a former Jordan driver in F3000. Irvine finished sixth and secured a point on his debut Formula One race at Suzuka. It was further memorable because Irvine unlapped himself against McLaren's Ayrton Senna, in order to overtake Damon Hill. After the race finished, an incensed Senna, infuriated by what he deemed as unsafe racing by Irvine in poor weather conditions stormed into the Jordan garage and punched Irvine in the face after Irvine pushed him in a heated discussion in which both drivers lost their temper.
