David Coulthard questions the FIA assessment of Red Bull power unit performance

Former Formula 1 driver David Coulthard has publicly challenged the FIA's use of the ADUO system to evaluate engine performance parity. The system, which recently identified Red Bull Ford Powertrains as the benchmark for internal combustion engine strength, denies the manufacturer additional development allowances while providing them to competitors. Coulthard argues that the mechanism is flawed because it ignores electrical energy deployment and other complex components of modern power units. He compared the regulation to evaluating an athlete based on a single body part rather than total performance., Coulthard suggested that other longstanding regulations, including grid penalties for component changes, are outdated and no longer serve their intended purpose in the current era of the sport. His comments highlight ongoing friction regarding how technical regulations balance competition across the field.
