Formula One statistics for Sunday's Qatar Grand Prix, the 20th race of the 22-round world championship.
Lap distance: 5.38km. Total distance: 306.66km (57 laps)
No previous race held there.
Start time: 1400GMT/1700 local
The circuit has hosted MotoGP since 2004, becoming a night race in 2008 when it also opened the season.
Qatar has signed a 10-year deal to host Formula One from 2023, after the 2022 soccer World Cup. A new circuit could be used from then.
The 5.4km Losail layout is fast and flowing and features 16 medium and high-speed corners.
The main straight is more than one km long and the surface is expected to be abrasive, which could mean high tyre wear. Overtaking could be tricky, with only one zone for the drag reduction system (DRS) to operate in.
Weather conditions will be warm and similar to what teams are used to in Abu Dhabi.
Qatar will be the 36th country to host Formula One.
