Grand prix tracks' DRS changes for rest of 2018 Formula 1 season

As part of the governing body's push to improve overtaking, it has already modified the DRS areas at a number of tracks throughout the campaign.

Now, along with a decision to lengthen the DRS zone on the start-finish straight at Monza this weekend, F1 race director Charlie Whiting has confirmed plans for the final races with changes being made at four other tracks.

At Sochi, the main DRS zone that runs down the start-finish straight and around Turn 1 will be extended.

For Austin, the DRS on the backstraight between Turns 11 and 12 will be lengthened.

The DRS zone at Interlagos after the Turn 14 kink onto the start straight will be lengthened by 100 metres, while both DRS zones in Abu Dhabi will be extended.

Although the ease of overtaking moves in Belgium last weekend led to questions about whether the DRS zone was too long, F1 race director Charlie Whiting did not believe there was a problem.

"Spa is different, isn't it?" he said. "Sebastian [Vettel] got past Lewis [Hamilton] without DRS and that's simply because you get a better run through Eau Rouge.

"We always see it here don't we? It'll be different on other circuits."
