Ahead of this weekend's German Grand Prix, the FIA has revealed a number of changes at the Hockenheim circuit.

A one-metre wide strip of 'Grasscrete' has been laid next to the track surface on the approach to Turn One.

Also, in order to prevent further damage to the grass verge at Turn 15, a 50mm high combination kerb has been laid behind the kerb on the apex.

Finally, drainage has now been provided in the drag strip around the outside of Turn 17, aimed at preventing the accumulation of water there.

Meanwhile, contrary to previous reports, for the first time at Hockenheim there will be two DRS zones. The detection point of the first is 110m before Turn One, with the activation point 60m after Turn One.

The second detection point is at the exit of Turn Four, with the activation point 260m after Turn Four.

Today's press conference will feature Nico Hulkenberg, Kevin Magnussen, Kimi Raikkonen, Nico Rosberg, Adrian Sutil and Sebastian Vettel, while tomorrow's press conference features Renault's Cyril Abiteboul, Marussia's John Booth, Lotus' Federico Gastaldi, Paul Hembery, Toto Wolff and Caterham's new Team Principal, Christijan Albers.
