[WSJ] THE TROUBLE with any Bugatti is legibility. Sure, they are fast; a modified Chiron set a series production road-car record of 304.7 mph in 2019. But the badges are so small and they go by so quickly. How are people supposed to read that?And thus the Chiron Pur Sport’s extraordinary fixed rear wing, a carbon-fiber scimitar emblazoned with the word. Also, should anyone wonder how many cylinders, the Pur Sport has "16" stenciled on its horse collar-shaped, 3D-printed grillwork—a charismatic touch drawn from the company’s racing history, if a little, um, AutoZone-y, in this presentation. Maybe uncheck that box.
