initially, the agreement between ford, cosworth and lotus was binding on all parties, and ford as the funder had no plans to sell or hire the dfv to any other teams. however, it occurred to hayes that there was no competition - the ferrari was underpowered; the brm complex and too heavy; the unreliable maserati; brabham was powered by the oldsmobile-derived v8 repco ; the overweight honda; while dan gurney's eagle weslake was beautiful, powerful and sleek, but often unreliable. hayes concluded that ford's name could become tarnished, and that they should agree to use the unit in other teams, and hence potentially dominate formula one. chapman, on the back of the pair's long friendship agreed, and hayes could release the dfv initially to the rival french team matra, headed by ken tyrrell with jackie stewart as a driver.
