Stats and facts
About the circuit: Oil-rich Azerbaijan secured its place on the Formula One calendar in 2016 as one of a new-breed of street circuits in Formula One. Held on the streets of capital city Baku, the six kilometre track was designed by F1's resident architect Hermann Tilke and includes long straights, right angle turns and a tight uphill section on the outer section of the old city. The event was known as the Grand Prix of Europe in its first year, but will be known as the Azerbaijan Grand Prix from 2017 onwards.
Keen to project itself as a modern, wealthy and sophisticated country, the grand prix is one of a number of high-profile sporting and cultural events to take place in Azerbaijan in recent years. In 2015 Baku hosted the inaugural European Games and it is one of the host cities for the UEFA Euro 2020 championships (not to mention its host status during the 2012 Eurovision Song Contest).
