Tech insight - loving the louvres in Hungary

Sauber (above, upper arrow) and Mercedes (below) have both followed the example set by Toro Rosso at the start of the season with these rear wing endplate shapes, the top section featuring open louvres to help control airflow. Mercedes also used this high-downforce solution last time out at Silverstone, where Sauber conducted shakedown testing with theirs. Sauber’s design also has slots (lower arrow) similar to those introduced by Red Bull and seen on other cars including the Ferrari.
