As Hill left Arrows after 1997 season to race for Jordan, the team contracted Finnish driver Mika Salo to partner Diniz for the 1998 F1 season. The 1998 season marked a new era for Arrows, as the team decided to build its own engines after buying out Brian Hart's preparation company. A V10 Arrows T2-F1 was made to power the cars for the team. It proved to be a difficult season, although both cars finished a respectable fourth and sixth at the eventful 1998 Monaco GP, and Diniz went on to score a single fifth place finish at the wet Belgian race. Arrows ended up finishing seventh in the Constructors' Championship, with a total of six points. Barnard left the team after a dispute with Walkinshaw, with Mike Coughlan taking over as technical director. At this point Zakspeed tried to buy Walkinshaw's shares in Arrows for around $40 million but terms could not be reached and the deal fell through.
