Brabham - Controversy

Controversy

The fan car and hydropneumatic suspension exploited loopholes in the sporting regulations. In the early 1980s, Brabham was accused of going further and breaking the regulations. During 1981, Piquet's first championship year, rumours circulated of illegal underweight Brabham chassis. Driver Jacques Laffite was among those to claim that the cars were fitted with heavily ballasted bodywork before being weighed at scrutineering. The accusation was denied by Brabham's management. No formal protest was made against the team and no action was taken against them by the sporting authorities.

From 1978, Ecclestone was president of the Formula One Constructors Association (FOCA), a body formed by the teams to represent their interests. This left his team open to accusations of having advance warning of rule changes. Ecclestone denies that the team benefited from this and Murray has noted that, contrary to this view, at the end of 1982 the team had to abandon their new BT51 car, built on the basis that ground effect would be permitted in 1983. Brabham had to design and build a replacement, the BT52, in only three months. At the end of the 1983 season, Renault and Ferrari, both beaten to the drivers' championship by Piquet, protested that the Research Octane Number (RON) of the team's fuel was above the legal limit of 102. The FIA declared that a figure of up to 102.9 was permitted under the rules, and that Brabham had not exceeded this limit.
