    The Stig crashed the CCX:

    As for the increased power of the CCXR on biofuel this is what I read:

    It a little secret. Normal "high octane" pump gas is 91 or 93 octane (depending upon where you live). In Europe you can get something about 95 octane (it is listed as 100 but is a different scale).

    E85 (with the 85% blend) has an octane equivalent of about 105 (on a USA scale).

    Since it is turbo charged, you can crank boost up without pre-ignition (knock). To give you an example, on my car, with 91 pump gas, I run about 17psi boost. With E85 i run 24psi and am in the process of hooking up a knock counter to determine if I can run more.

    Also, the ethanol has much better evaportive cooling that gasoline and 30% more is used (means denser air going in and less detonation).

    But...here is the but....you can achieve about the same power using 104 octane unleaded race fuel.

    The difference is
    E85 = under $3 a gallon (i only buy in summer so not sure what prices are now...but last summer it was $2.40 a gallon or so)

    104 Octane Race fuel = $8+ a gallon (again I haven't bought it for a while since I switched to E85 for race fuel...but when E85 was $2.50ish a gallon race fuel was about $8.50 a gallon)

    So the answer: it is cheap race fuel due to high octane equivalent.

    Seems a tad heavy for one of those super-duper cars. The Bugatti moreso.

    Though I have to imagine they weren't engineered for the same type of driving as F1 cars.

    Really cool.

    About the closest thing you can get to a TRUE race car for the street is:

    [​IMG]

    Its a Dauer 962. They are a road car built from a race car.


    Or this is close: but is a production car turned into a race car...I have actually seen exactly ONE of them on the street (parked)

    No one knows who The Stig is (as you probably know). What you may not know is that The Stig isn't always the same person. One reason for the secrecy of his identity is that quite often car manufacturers (especially of cars like the Konneigseg and Bugatti Veyron, though maybe not those specific two) will only allow the car on Top Gear if their driver actually drives it (instead of The Stig, who was Ben Cunningham until about two years ago BTW). The idea of The Stig gives Top Gear a way to accommodate this request without anyone really realizing that it is happening or when.

    Obviously they aren't going to tell you when this happens or on which car.

    Top Gear suggested that the CCX have a wing added. This helped the performance on the track but hurt the straight-line speed. I don't know if the wing was put on the production cars or not but with no rear downforce there is no way I would want to push it to the limits.

    The Bugatti is engineered to be able to meet it's advertised top speed while having all the amenities (AC, CD player and several other luxury items) on it. That's why it is so heavy, so powerful, and why the tires cost about $30,000 a set. Or part of the reason anyway.

    I have only ever seen one Veyron on the road. It was on an Autobahn between Munich and Stuttgart. I don;t think they were worried about AC.

    What you don't see, is the Veyron was not broken down. The truck on the the side had a racing team logo on it.
