Used chassis idea is knocked back

Under Mosley's proposals, teams would have been able to buy cars from other outfits off the shelf, rather than having to design and build their own, as with the current regulations. McLaren boss Ron Dennis feels that the rule could have polluted the purity of F1.

"Everyone had different views but mine was not supportive," said Dennis. "If we opened that door, it would be an opportunity for a manufacturer to buy two cars and we could have ended up with, say, two Williams-BMWs run by Williams and two by the factory. I couldn't see that that was a positive move. Or, the factory could have a 'B' team using the two current cars. I think it would just pollute the purity of Formula 1."

Dennis added, however, that he is not against the idea of common components. "I'm supportive of the idea that maybe the engine/gearbox and rear suspension and maybe the front geometry can be shared, thereby reducing cost because the team would only need its own monocoque and bodywork. But I do believe that each Formula 1 car should look different."
