Any VF performance figures out there yet?

[1TUFFUTE]

Because i have my own real world experience against the very first vf I've seen. A black Ssv sedan at low speeds coming off a 2 lane roundabout we both booted it for a little bit......he was an auto aswell and chirped twice.....but was almost a fullcar length behind before we both backed off. I was very surprised ......thought they were lighter faster and better grip...amount other things.
Anyway. Anyone seen how fast these new Vfs really are.
