The Abu Dhabi Grand Prix (Arabic: سباق جائزة أبوظبي الكبرى) is a Formula One motor racing event. It was announced in early 2007 at the Abu Dhabi F1 Festival in the United Arab Emirates. The first race took place on 1 November 2009, held at the Hermann Tilke-designed Yas Marina Circuit. The inaugural race was Formula One's first day–night race, starting at 17:00 local time. Floodlights used to illuminate the circuit were switched on from the start of the event to ensure a seamless transition from daylight to darkness. Subsequent Abu Dhabi Grands Prix have also been day–night races.
