Paul Hembery says the new F1 tyre regulations made the Australian Grand Prix a more thrilling spectacle as teams were able to open up different strategies after the red flag stoppage.

With Fernando Alonso and Esteban Gutierrez suffering a huge smash on lap 18 the race in Melbourne was temporarily suspended to clear debris.

The stoppage enabled teams to radically switch strategies, with race winner Nico Rosberg swapping his red-banded supersofts for the mediums tyres to reach the chequered flag effectively without stopping during the race.

Haas' Romain Grosjean and Williams' Valtteri Bottas were also profiteers of similar strategies to the Mercedes driver while Sebastian Vettel provided a challenge using the supersofts and softs.

Paul Hembery, Pirelli's motorsport director, says the new regulations provided the opportunity for opposing tactics which created the intriguing race climax and is confident for a similar story for the rest of the 2016 season.

"The grand prix started and ended with a tactical tyre battle, but a red flag after 18 laps reset the race, giving it a very different complexion with tyre changes allowed," Hembery said. "After starting with the same used supersoft compounds, Ferrari and Mercedes chose opposite strategies in the second part of the race, with Mercedes running two-thirds of the total distance on the medium tyre but closely challenged by Vettel on the soft.

"This goes to show how the new regulations have helped to open up a number of different approaches to strategy, with nine of the 16 finishers taking advantage of all three compounds on offer and five completely different strategies covering the top six places.

"As well as the expected battle at the front, Romain Grosjean finished an excellent sixth for the Haas team on its debut by effectively not making a pit stop at all: instead swapping from soft to medium during the restart, which was an inspired decision."
