It\'s always special when a one-off supercar gets spotted in the flesh, especially when it\'s a one-of-a-kind Bugatti Veyron Grand Sport.Dubbed the Veyron L\'Or Blanc (\'White Gold\'), the supercar was tracked down and videoed in Paris. It\'s the first vehicle to sport porcelain elements inside and out, and was created in collaboration with Konigliche Porzellan-Manufaktur (KPM) who used the finest porcelain in the body panels and several precision painters to apply five layers of clear coat.Porcelain is also used for the inlays of the center wheel badges, the oil filler cap, the fuel filler cap and the signature EB badge at the rear. The exterior is surrounded in thin blue lines to give the Veyron a very abstract look.While applying the bodywork, designers were very meticulous with the finest details. If the detailed lines didn\'t please them, they placed a correction tape above the original line.They repeated this process until the final line has the right tension and character. The end result is something Jackson Pollock would be proud of.The Veyron Grand Sport is powered by an 8.0-liter W16 quad-turbocharged gasoline engine that produces over 1,000hp and around 980lb-ft of torque, making this the fastest convertible in the world.It can go from 0-62 in 2.46 seconds and hit a top speed of around 250mph (with the roof in place). And whoever is driving the L\'Or Blanc forked out €1,650,000 (or $2,400,000) for the pleasure.
