Um, guys, this is a street car:
Last time I checked, it holds the single lap record at the Nurburgring for street vehicles because it's street legal in Europe and the UK.
Now Dean is implying that the Bugatti is more streetable than the Aero TT. First, *no* car is "streetable" at 250 mph. At that speed... hell at any speed over 100 mph... you have to be driving like you're in a racecar because your life depends on it. I don't care how nice the stereo is, how many cupholders there are, whether or not the car looks like a racecar or a street car... whatever. All that matter at those speeds are how stable the car is.
So, as far as "streetable" is concerned, you have to ask yourself how comfortable the car is at sane speeds. Since no-one in this thread has ever driven either of these cars, we're just going to have to go with the reviews. And the review of the Aero TT is that it is indeed streetable. It's got a nice interior, decent road manners, and can even get over that speed bump that Dean mentioned (by use of a suspension lift... the same way the Enzo gets over speed bumps, and *gasp* the Veyron).
As far as engineering's concerned, I too am more impressed by the Veyron's engineering... it's got a crazy complicated motor, AWD, watercooled brakes, etc. It's an engineering masterpiece. It's also an exercise in engineering masturbation. Making 1000hp is not all that impossible these days, and a quad-turbo 16cyl motor is easily not anywhere near the right way to do it, unless you're just trying to make an exotic car. Likewise, going 250 mph isn't that hard either, just make the car light and slap wings on it for downforce. Sure the constraints of "street legal" make it harder, but really the "right" answer to the problem is to take a traditional lightweight sports car with (OMG!) splitters and side skirts and slap a big old turbo V8 in there.
Racecars look the way they look for a reason... to engineer a street car to do something that racecars do all the time (go fast) a smart engineer would borrow as much proven technology as they can from the racing world. IMO, the Veyron is a poor design because it reinvents the wheel... instead of mating a compact lightweight high-power motor to a light car, they dropped a MASSIVE motor into a 4000lb car and then engineered a ton of new crap to keep the car driveable at speeds that would be shrugged off by another car built correctly. Frankly, the car is successful in spite of itself!
I guess my point is, the Veryon won't sit at the top of the production-car speed chart for long, because it's actually a very poor design for the goal of going fast. Granted it's a marvel of a vehicle, but it's really only marvelous because it's so over-engineered. There are already one-off street cars that can beat it, all it takes is some company to build a special edition "production" car based on established designs that whoops its ass... like this Aero TT.
