Basic changes in vehicle design in the F1 racing of 2019

Only a few days left, the rotation of Formula 1 cars rolled. Let’s find out about the most fundamental changes in design compared to the previous season.


1. Wind vane first

The most noticeable change in the design of this year’s Formula 1 car is the front wing, which is larger in size, but the design has to be streamlined to comply with the FIA ​​rules. For years, teams have been trying to create front wings with extremely complex designs, both to create compressive forces that help the car to stick more at high speeds, both to make the air blown away. area of ​​the front two wheels, help crab better.

More specifically, the front spoiler of F1 car this year has the width increased by 200mm, the size is 2 meters, the height increases by 20mm and the nose of the vehicle extends forward by 25mm. This year, the FIA ​​banned racing teams from taking advantage of the wind blades to change the airflow impacting on the front wheels of the racing car, but instead only worked to create the compression force to help the car more stable at high speeds.

2. The rear spoiler

In order to help the races become fair and there are many opportunities for the car to overtake the car in advance, the rear spoiler is raised to 20mm to help the airflow that the front vehicle creates is blown higher, without impact. Go to the car behind while chasing.

In addition, the drag reduction system mounted on the rear wing is larger than 20mm in height, and when opened, will make the vehicle run faster than the 2018 DRS by about 25%, according to FIA calculation. The rear of the rear wing must have two additional LED lights to increase the ability to identify the vehicle in front of each race in bad weather conditions.

3. Cooling brake pads

Brake ducton F1 racing cars this year will have a much simpler design, when the FIA​​ prohibits teams from using complex designs to cool the brake pads, sometimes up to over 500 degrees Celsius, has created an aerodynamic advantage for the car. There are no more carbon-fiber details, but the wind-cooled port will only serve a single task, like the name of this detail.

The carbon fiber parts of the F1 body, right behind the front wheel are also required to have a simpler design when their height is lowered by 150mm, and reaching out to 100mm in front to handle the airflow from the wind vane first. Once again, designing a car like this will make the rear car more likely to chase in each race when the dirty airflow (also known as rooster tail) that the vehicle in front creates no longer affects it too much.

4. Weight of the driver

In the past, when measuring the volume and size of Formula 1 cars, the FIA ​​often weighed both the vehicle weight and the weight of the driver sitting in the car. In this season, the dry weight of the vehicle must be at least 740kg and more importantly, the driver must weigh at least 80kg, including clothing, equipment and helmets.

If the driver does not meet this number, the team will have to put additional ballast pieces into the cockpit to ensure an 80kg figure. These dumbbells must be placed in the cockpit instead of other locations to increase the aerodynamic balance of the vehicle.

5. Add fuel

To stimulate riders to test themselves and push every race to the limit, in each race of the 2019 F1 season, the fuel tank will be dumped up to 110kg of fuel compared to 105kg as last season. Combining both the 1.6L turbo V6 and the energy recovery system from braking and heat, riders will no longer have to worry about fuel economy in long races.

6. New gloves and helmets for riders

The FIA​​ requires all racers to wear a new glove with sensors sewn into the fabric to monitor the heart rate and oxygen levels in each blood. These data will be sent to the emergency team at the races to take timely action if serious collisions happen.

The new helmets of F1 season riders this year are designed and manufactured according to new standards, FIA 8860-2018. This helmet is more resistant to bumps and prevents the car’s debris from hitting the steering wheel better in bumps at speeds of 300 km/h. Sunglasses have a height of 10mm lower to minimize the risk of foreign objects penetrating this glass, causing harm to riders.
