In 1998 B3 Technologies began working for the Arrows Formula One team, but the deal soon descended into dispute when the Prost team also subcontracted the R&amp;D outfit. The Arrows A19 scored the last points for a fully Barnard-designed car when Pedro Diniz placed fifth in the chaotic and rain-soaked 1998 Belgian Grand Prix. Ultimately, Barnard worked as a technical consultant for the Prost team until its demise in 2001 when he chose to move into motorcycle racing, becoming Technical Director of the Team KR Grand Prix motorcycle racing team.
