The thing is though it runs on 104 octane gas (by American calculations, that's about 110 octans by European calculations - RON110, I think

) The finest gas I've ever seen in Europe is RON100 - Shell V-power Racing/ Shell Optimax, OMV Super 100, Benzina Blue Octans 99 here in the Czech republic and others. I guess it is race gas then, which as far as I know costs about 10 or more USD per liter. That's about 40 per gallon. But well, I'm convinced a potential owner can afford that especially if he wants to use it rather rarely on race tracks and for drag races.
But my point is that if you filled up a veyron with such gas, it would do probably over 260mph, with an appropriate ECU modification, which is needed if the engine is to take benefits from the gas.
