Apparently they tested the R500 on Top Gear in the UK tonight and and the Stig hustled it around the test track faster than the Veyron
Word is that it was 1 degree C (32 F) when they tested it and couldn't get enough temperature into the tires, so it could possibly go faster.
Hopefully there will be some video available online soon
1:17.1 – Gumpert Apollo S
1:17.3 – Ascari A10
1:17.6 – Koenigsegg CCX (with Top Gear wing)
1:17.8 - Pagani Zonda F Roadster
1:17.9 – Caterhams R500
1.18.3 - Bugatti Veyron 16.4
1:18.4 - Pagani Zonda F
1:18.9 – Maserati MC12
1:19.0 – Ferrari Enzo
Here is some video of a private car doing 1:17.4 but it is not official nor is it on the production car tires
