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.

"Drivers have historically loved Silverstone," said Damon Hill, the 1996 world champion who is now BRDC president, "and we hope we hope that we have designed a challenging, exciting track for them which will make them like racing here more than ever."
