Audi R8 GT Spyder Sports Car, 333 Lucky Number?

Not long ago, the Audi unveiled a limited R8 GT in coupe form for only 333 units available. Now the Audi announced a new Sports car in R8 model, an open-top version, R8 GT Spyder, which will be also produced in only 333 units. What is the special about 333 number? Is it a lucky number? (Perhaps I should ask directly to Audi about this).

The Audi R8 GT Spyder is having a theme like R8 GT coupe and tagging with its individual number on the gear level knob . Powered by 5.2-liter V10 engine with an aluminum crankcase and engine frame is made of ultra-light magnesium, the new car is not only having a lighter weight, but also boasts 412kW(560 hp) peak output, 3.8 seconds from zero to 100km/h, and 317km/h top speed. In addition, the car performs 14.2l/100 km combined fuel consumption, and 332g/km combined CO2 emissions.

Unfortunately, for the US customers must wait more longer for this car. The Audi announced the R8 GT Spyder will be hit market in 207,800 euros or around $304,000 in Germany. It means the new car will hit European market first, right? Only 333 units, Does US market have quota? [Dandy Gadget Source]
