Horacio Pagani is a man who, without benefit of formal education in aerodynamics or engineering—a European businessman who doesn’t speak English, a designer who can’t tell you what a PDF is—has managed to pluck from the naked air of his intellect this thing called the Pagani Huayra, a gull-winged, $1.2 million hypercar, a painterly masterpiece with comic book performance, a zero-altitude fighter jet and about the most radical way to get from Point A to 225 mph.
