Since 2014 F1 cars have been powered by 1.6 litres, V6, Turbocharged, Hybrid engines which currently produce around 800 horsepower.
In 2017 the aero regulations were revised with the intention of making the cars up to 5 seconds faster from 2015 and less sensitive to the wake of cars in front (details below).
New for the 2018 season is the controversial ‘Halo’ head protection device, which is designed to prevent debris from hitting the driver head in light of recent deaths of Henry Surtees, Jules Bianchi and so on.
The FIA has increased the weight limit of the cars by 6kg to allow for the added weight of the halo.





The front wing will be increased in width by 150 mm to 1,800 mm and will also be swept back rather than straight cut, sticking out a further 200mm and with simpler end plates.
It is believed that this will make the car less sensitive to dirty air.TYRES
The front tyres will be widened by 60 mm to 305 mm and the rears by 80 mm to 405 mm, providing much more mechanical grip.SUSPENSION
The width of the whole car is being increased by 200 mm to 2000 mm, making the cars a lot wider, again providing more mechanical grip.

The floor will have a larger maximum width of 1600 mm with a 100 mm variable edge radii allowing for larger side-pods and creating a sort of ground effect.
The reference plane (lowest part of the car) will be 100 mm further back.
The diffuser will be much bigger at 175 mm high, 1050 mm wide and staring 175 mm in front of the rear axle.

1600 mm max body width.
Swept leading edge of the side pods and Larger bargeboards with a smaller exclusion zone.

A 200 mm wider rear wing be introduced measuring 950 mm wide, as well as being 150 mm shorter at 800 mm.
They will also have swept and tucked in end plates.

As a result of these changes, the cars will be 22 kg heavier than before and thus drivers will be allowed a maximum 105 kg of fuel for the race, 5 more than 2016.

A change in the reguations for 2018 will ban the use of shark fins and T-wings on the cars engine covers which reserfacedin 2017 with a loophole in the regulation changes.
