Mercedes are the only team to have won in Russia since the first race in Sochi in 2014.
Hamilton won in 2014 and 2015, Nico Rosberg in 2016 and Bottas last year.
Until last year, Mercedes had led every lap at the circuit and started every race on pole. (Hamilton 2014, Rosberg 2015 and 2016).
Bottas took the first fastest race lap of his F1 career in Sochi with Williams in 2014 while 2017 was his first win (in his 81st race).
The Finn was also (with Williams in 2016) the first non-Mercedes driver to start on the front row in Sochi.
The layout is designed by Hermann Tilke and runs clockwise around the 2014 Olympic Park venues, partly on public roads. There are 12 right and six left-hand corners.
Williams’ Sergey Sirotkin is the only current Russian F1 driver.
Russian president Vladimir Putin has attended every race in Sochi so far.
Hamilton has seven wins this season to Vettel’s five. Daniel Ricciardo has two and Max Verstappen one.
Hamilton has 69 victories from 223 races and is second in the all-time list behind seven-times world champion Michael Schumacher (91). Vettel, third on the all-time list, has 52 and Ricciardo seven.
Ferrari’s Kimi Raikkonen has now gone 109 races since his 20th and last win, in Australia in 2013.
Ferrari have won 234 races since 1950, McLaren 182, Williams 114, Mercedes 83 and Red Bull 58. Former champions McLaren and Williams have not won since 2012.
Hamilton has a record 79 career poles, Vettel 55.
Verstappen, who celebrates his 21st birthday on Sunday, can still become the youngest ever pole sitter although likely engine penalties are set to deny him the chance of being the first 20-year-old on pole.
The current youngest is Vettel, who did it at 21 years and 72 days.
Hamilton has 129 career podiums and is second on the all-time list behind Schumacher (155). Vettel has 108, Raikkonen 100.
Mercedes’ Valtteri Bottas has had five second-place finishes this season.
Hamilton leads Vettel by 40 points with six races left.
Mercedes are 37 points ahead of Ferrari in the constructors’ championship.
Every driver on the starting grid has scored this season.
Hamilton can take his 80th pole on Saturday and 70th win on Sunday.
