Mercedes claims it can't match McLaren's recent upgrade push because the cost cap won't allow it. Toto Wolff says the team budgeted to spread development evenly across the season and now lacks headroom to react after McLaren's two-stage package transformed Lando Norris into a back-to-back winner at Zandvoort.

A weighted cost analysis puts Mercedes well behind the leading trio.
