Did Renown and Repulse directly influence the design of German surface raiders such as Scharnhorst and Gneisenau?
Short answerThey could not be ignored, but the German ships were shaped more immediately by French and Russian opponents; Bismarck and Tirpitz were the clearer one-for-one British challengers.
NotesRenown and Repulse formed part of the threat environment facing any German surface raider, though they were not the sole design opponents for Scharnhorst and Gneisenau. German planning focused heavily on France and Russia, while British ships were likely to include opponents that could outpace or outgun a raider. Only with Bismarck and Tirpitz did Germany field battleships intended more clearly for a one-to-one contest with the strongest British capital ships. The answer separates broad threat awareness from a direct design-response claim.
