Formula 1 chief Ross Brawn says he is encouraged by the sport's new aerodynamic regulations, believing they improved overtaking and helped create "thrilling battles" at the Australian GP.
The changes, which include simplified, larger front and rear wings, were introduced for the 2019 season in a bid to allow cars to race closer together, thus increasing the chances of overtaking.
While it was hard to judge the new rules at the season-opener - Melbourne's Albert Park is a street circuit and one of the narrowest tracks on the calendar - Brawn was pleased with what he saw.
Brawn added: "Clearly those weren't all down to the new aerodynamics, as the performance of the midfield teams especially has closed up dramatically.
"However, several drivers said the cars felt more neutral when following another when compared to previous years."
The big test for the aero changes will come at the next races in Bahrain and China - where overtaking is always easier - with Brawn admitting the Australian GP wasn't an "accurate" reflection.
"I'd prefer to wait for at least another three races before drawing any conclusions," he said.
"However, the initial signs are encouraging."
