The Hockenheim stewards are investigating Red Bull after FIA technical delegate Jo Bauer reported that after examining the engine torque maps of the RB8s of Sebastian Vettel and Mark Webber after qualifying, “it became apparent that the maximum torque output of both engines is significantly less in the mid rpm range than previously seen for these engines at other events.

“In my opinion this is therefore in breach of Article 5.5.3 of the Technical regulations as the engines are able to deliver more torque at a given engine speed in the mid rpm range. Furthermore this new torque map will artificially alter the aerodynamic characteristics of both cars which is also in contravention of Technical Directive 036-11.”

Article 5.5.3 says that “The maximum accelerator pedal travel position must correspond to an engine torque demand equal to or greater than the maximum engine torque at the measured engine speed. The minimum accelerator pedal travel position must correspond to an engine torque demand equal to or lower than 0Nm.”

The FIA placed tighter restrictions on engine maps ahead of this season as part of a package of rule changes designed to eliminate the use of exhaust-blown diffusers. Bauer’s statement suggests the FIA may suspect Red Bull have found a way to circumvent the changes.
