Wider cars, fatter tyres, more fun....

Formula One has undergone major rule changes, with wider cars and fatter tyres providing a new look and bigger challenge. The sport is also under new ownership, with Liberty Media taking over and former commercial supremo Bernie Ecclestone sidelined. The following looks at what differences fans will see when the championship starts in Australia on March 26.

LAP TIMES
Cars are expected to lap between three and five seconds faster due to revised aerodynamics and the tyre changes. The fastest lap in Barcelona testing was quicker than any pole position there since 2007. The gain is coming through the corners, with many taken flat out thanks to improved downforce and grip. That means higher G-forces on drivers. Straight line speeds will be slower but drivers can stay on the throttle for longer.

Tyres
Tyres are fatter. The width of the rears has expanded from 325mm to 405. The fronts are 305mm compared to a previous 245mm. The wheel rims remain unchanged. Pirelli expects the tyres to offer about 25 percent more grip and last longer, which is likely to mean fewer pitstops.

Aero dynamics
Front wings are wider, stretching out to 1,800mm from a previous 1,650. Rear wings are also wider but lower, helping give the cars a more aggressive look. Cars are wider, longer and heavier. The total width has been expanded to 2,000mm, up from 1,800mm - a return to pre-1988 dimensions. The cars are 20kg heavier at 722kg and "Shark fins" have appeared on most of them, leading off the airbox behind the drivers head. The revised aero could make it harder to overtake, however.

Fuel
The fuel allowance has been raised by five kg to 105kg to compensate for increased consumption due to the extra grip, but there are concerns that is not enough. That could lead to evident fuel saving at the end of some races.

Champions
For the first time since 1994, the season after Alain Prost won his fourth title and then retired, Formula One will have no reigning champion on the starting grid with Nico Rosberg quitting in December.

Jenson Button, the 2009 champion, has also departed but four previous titleholders remain - Hamilton, four-times champion Sebastian Vettel (Ferrari), 2007 winner Kimi Raikkonen (Ferrari) and double champion Fernando Alonso (McLaren).

Teams
The grid has shrunk to 10 teams, and 20 drivers, following the demise of Manor. Toro Rosso have switched from Ferrari to Renault power.

Races
The season has 20 races, one fewer than 2016, due to Germanys absence for financial reasons and no new additions.

New faces
Button, Rosberg, Brazilian Felipe Nasr and Mexican Esteban Gutierrez have left. In come Belgian Stoffel Vandoorne at McLaren and 18-year-old Canadian Lance Stroll with Williams.
