Porsche had the Brands Hatch Sprint peak, but Mercedes-AMG and BMW gave the cleaner depth readings once Race 2 stripped away the usual noise.
Mercedes-AMG’s Red Bull Ring opener was not just a Race 2 win. It was the first useful read on DTM’s new tyre and BoP regime.
Issue 008 examines Mercedes-AMG’s engineering-chain question, BMW’s multi-programme coherence, Porsche under regulatory pressure, and WEC’s new invisible-BoP regime.
Paul Ricard data refined. Mercedes-AMG tyre finding holds at one circuit. BMW programme correction issued. Porsche customers collided with each other.
