Silverstone's long-term commitment to the future of the British Grand Prix will be put on very public display this week when the Duke of York formally opens the revised 3.666-mile circuit on Thursday (29 April), emphasising  an end the uncertainty which had hung over the race for more than a year after the ill-starred bid from Donington Park to take over the fixture.

The track layout has been radically re-shaped with the track now turning sharp right at Abbey Curve onto a new infield section which leads out onto the long straight of the national circuit ­ now titled the Wellington straight - to feed back onto the existing track at Luffield, just before Woodcote.

The investment in this dramatic new circuit infrastructure ­ to be followed by a new pit/paddock complex on the exit of Club Corner in time for the 2011 Grand Prix ­ reflects a massive financial commitment on the part of the track's owners, the British Racing Drivers' Club who have committed an estimated £300m in future race fees to Bernie Ecclestone's organisation FOM over the planned 17 years of the new contract.
