Baku City Circuit information by F1.com:
When was the track built?
It wasn’t – Baku is the newest street circuit on the Formula 1 calendar, joining the ranks of Monaco, Melbourne and Singapore.
When was its first Grand Prix?
The first Grand Prix in Baku was held in 2016, as the European Grand Prix. That was followed by the inaugural Azerbaijan Grand Prix in 2017, which witnessed one of the biggest upsets of the season, with Daniel Ricciardo winning out from Valtteri Bottas and the Williams of Lance Stroll, while Lewis Hamilton and Sebastian Vettel engaged in some argy-bargy behind the Safety Car.
What’s the circuit like?
A mixture of wide and open and tight and twisty. The lonnnnng main straight along the Baku shoreline is a slipstreaming mecca, and with cars able to run three abreast into Turn 1, the action often looks more IndyCar than F1. However from there, the track loops around into the city’s narrow, winding Icheri Sheher old town, dramatically wending past Baku’s medieval city walls. As in Monaco, slightest mistakes are punished quickly and severely, while set-up wise, the teams are forced to choose between downforce for the twisty bits and less drag for the straight.
