This video from the guys at Dragtimes.info is a "what if" split screen showing acceleration from 0-300+ km/hr in a AMS Alpha 12+ Nissan GT-R and a Bugatti Veyron Super Sport. Its not realistic to compare these two cars, as they really don't share anything in common, but as long as cars and people exist, you will always see some kind of comparison. The GT-R is a fast, but "in-expensive" supercar. The Bugatti is a hyper exotic to top all produced hyper exotics Check out the side by side video after the break.
