Bryan Hart, the constructor of the Hart-V8 in the Arrows cars, has offered his apologies to Jos Verstappen for the performance of the engine. Verstappen had problems with the valves of the engine both in Melbourne as in Sao Paulo last weekend. Verstappen pushes the engine much further to its limit than his predecessors and his team-mate Rosset. The Arrows-team had already limited the engine with 300rpm but it still broke down. Hart said that the problems can't be solved within two months.
