Red Bull, with Australian Daniel Ricciardo and Dutch teenager Max Verstappen, were the only non-Mercedes winners last season.
Triple world champion Hamilton has won at least 10 races in each of the last three seasons. He won 11 in 2014 and 10 in 2015 and 2016. He is the only driver to have won 10 races in a season and not taken the championship that year.
Hamilton has 53 career victories, putting him second in the all-time list behind Schumacher (91). Ferrari's Sebastian Vettel has 42, McLaren's Fernando Alonso is on 32 and Ferrari's Kimi Raikkonen 20.
Ferrari have won 224 races, McLaren 182, Williams 114, Mercedes 64 and Red Bull 52. McLaren have not won for 78 races, a run that dates back to Brazil 2012.
Hamilton was on pole 12 times last season and now has 61, four short of the late Ayrton Senna's career total and seven behind Schumacher's record 68.
Mercedes were on pole in 20 races last year and have been on pole in 56 of the last 59.
There is only one complete newcomer this season - Canadian Lance Stroll at Williams.

Eight of the last nine races in Australia have seen the safety car deployed.
McLaren's last podium finish was in Australia in 2014 (Magnussen).
Russian Daniil Kvyat has failed to start the last two races in Melbourne due to technical problems.
