The prepare of thought: Neither high-speed bell equals increased strain, nor equals increased efficiency. So, BMW technicians went in quest of gasoline that was just a bit bit decrease than the octane restrict set by the laws.

By working with consultants on this discipline, they had been capable of create an correct design of unintended lead-free gasoline. After the competitors’s official protest, an official gasoline investigation confirmed past doubt that BMW knew the restrict precisely and adhered to it.
