As of 2018 Formula 1 cars are required to have a standard cockpit protection device dubbed the ‘Halo’ which is designed to protect the drivers head for flying objects such as loose wheels.
CAR SIZE AND AERODYNAMIC REGULATIONS as of 2019:
- The front wing must be 2000mm from end to end whith flat end plates and no more than 5 single elements on the main plane.
- Height has been increased by 20mm from 2018 and the front tip is 25mm further forward.
- Underwing streaks have been restricted to two on either side.
- The front tyres are 305 mm wide and the rear wheels are 405 mm wide, with 13″ rims.
- Brake ducts have been simplified and can no longer have aerodynamic devices attached to them.
- Blown wheels nuts have also been banned.
- The width of the whole car is fixed at 2000 mm measured from the ends of each wheel.
- The diffuser sits at 175 mm high, 1050 mm wide and starts 175 mm forward of the rear axle.
- Side bargeboards are increased in length by 100mm from 2018 and lowered by 150mm.
- The rear wing is 870 mm wide, 1050mm long and 70mm higher at the tip than 2018.
- The DRS flap opening is now 85mm in height making it more powerful than 2018.
- There is now a limitation on pressure equalising slots on the end plates.
There are also a number of rules changes for the 2019 season designed to improve safety and make the sport simpler.
Three Tyre Compounds:- As of 2019, only three types of tyre will be used at each race. While the compounds themselves will remain the same (although now called C1-C5) and Pirelli will still bring three different compounds to each race they will only be referred to as Soft, Medium and Hard and coloured red, yellow and white respectively. This is to make things simpler for casual fans who don’t understand the up to 8 different compounds.
Biometric Gloves:- For 2019 all drivers will wear biometric gloves with integrated sensors which measure the driver’s heart rate and oxygen levels which is fed directly to the medical team allowing them to detect any potential symptoms before arriving at a crash.
Rear Wing Lights:- All cars must now have two LED lights in the rear wing endplates in addition to the central light, this is is to make the cars more visible during wet weather.
Fuel Allowance:- Each car can now race with a maximum fuel weight of 110kg up 5kg from 2018 and 10kg from 2014 when the hybrid engines were introduced. This is to allow drivers to race a full power for longer.
Car and Driver Weight:- As of 2019, the weight of the car and driver will be considered separately. This is to help the heavier drivers as lighter drivers must now put ballast in the seat rather than where is best for optimal weight distribution.
