Jordan's 'B' version of its EJ10, tested at Silverstone last week, will not now make its race debut in Austria this weekend.
The car, which features heavily revised aerodynamics, was driven by Jarno Trulli and Heinz-Harald Frentzen at the test, proving 0.3s a lap faster in Frentzen's hands. But it will now make its debut at the German Grand Prix at the end of the month, following a decision to put more development miles on it and to build up a viable stock of new parts.
The changes to the car are so fundamental that the EJ10B will require a new crash test before being allowed to race. This would leave the team with only two full sets of the revised parts - which include new sidepods, diffuser, barge boards and front wing endplates - for the Austrian Grand Prix.
