F1 teams often talk about track layouts and how they affect competitiveness. Although the narrow and twisty layout of the Hungaroring is often compared to Monaco, in actual fact it is a much faster circuit, with longer straightline sections.
But that alone is not enough to explain why Mercedes was so dominant here this year. This was its second biggest winning margin of the season, bettered only by the particular circumstances of April's Chinese GP, where the Ferraris ran into each other on the first lap and Ricciardo's Red Bull suffered a puncture.
It's likely that re-surfacing the track and re-profiling the kerbs of the Hungaroring for 2016 played further into Mercedes' hands, taking away the sort of bumps and rough edges that unsettle cars and make them more difficult to drive, allowing the Mercedes drivers more space to stretch their legs.
