The owners of the Silverstone circuit in Northamptonshire are claiming it will be one of the fastest on the FIM MotoGP World Championship when it joins the series race calendar in 2010.
Changes to the circuit, which is currently used for Formula One and several national championships, will feature a new section of track running from the approach at Abbey Corner to a hairpin at the inside of Becketts.
The circuit will be 5.67 kilometres in length, 0.53 kilometres longer than at present, and mathematical simulations have produced data showing the average lap time for MotoGP riders will be one minute 51.456 seconds.
That would be at an average speed of 182kph, 3kph faster than Phillip Island in Australia which is currently the fastest circuit in MotoGP.
The changes at Silverstone will be subject to homologation by the FIM before the circuit can join the MotoGP race calendar next year.
