This year also marks one of the biggest regulation shake-ups in the history of the sport, intended to make the cars faster and thus potentially boost overtaking.
Bodywork and tyres are the centre of attention, with both getting wider in order to boost downforce and grip. This makes the car physically harder to drive.
Tyres are around 25 percent wider than in 2016.
The front wing span is increased from 1650mm to 1800mm, and the height of the rear wing is reduced to a maximum of 800mm, down from 950mm previously.
On the grid, the number of teams has gone down from 11 to 10 following the exit of Manor.
Defending World champion Nico Rosberg has not returned to defend his title following his stunning retirement immediately following last season.
Valtteri Bottas has replaced Rosberg and is looking to be a strong contender this year.
The only other big names to make moves were Jenson Button, who took a sabbatical from racing this season but remains as a reserve driver with McLaren, and Felipe Massa, who has unretired and is back with Williams.
