These brake systems are extremely effective at temperatures up to 750° C (1,382° F), even though they are lightweight. To help reduce wear and tear and increase braking performance, carbon fiber discs and pads are now used.

This causes the brakes to glow red-hot when they are used. The big difference, of course, is that the brakes used in Formula One must stop a vehicle traveling at Иspeeds greater than 200 mph. You would recognize all of the parts of the disc brakes found on Formula One cars. Before any race, a team will tweak suspension settings to ensure that the car can brake and corner safely, yet still deliver responsiveness of handling.īrakes. To keep things simple here, we'll say that almost all Formula One cars feature double Дwishbone suspensions. Those components include springs, dampers, arms and anti-sway bars. The suspension of a Formula One car has all of the same components as the suspension of a road car. That's more than four times the weight of the car itself. The result of all this aerodynamics engineering is a combined downforce of about 2,500 бАkilograms (5,512 pounds). Most иincorporate a diffuser, an upward-sweeping device located just beneath the engine and gearbox that creates a suction effect as it funnels air up and passes it to the rear of the car. Beyond that line, engineers have free reign. The bottom of today's cars must be flat from the nose cone to the rear axle line. These so-called 'ground-effect' forces were soon outlawed and strict regulations put in place to govern undercarriage design. Сthat sucked the entire vehicle downward. Using a unique undercarriage design, they were able to extract air from beneath the car, creating an area of low pressure Lotus engineers discovered in the 1970s that a Formula One car itself could be turned into a giant wing. The angle of both front and rear wings can be fine-tuned and adjusted to get the ideal balance between air resistance and downforce.

Airplane wings create lift, but the wings on a Formula One car produce downforce, which holds the car onto Wings, which first appeared in the 1960s, operate on the same principles as airplane wings, only in reverse. Wings, a diffuser, end plates and barge boards increase downforce. Formula One cars are low and wide to decrease air resistance. That's because any vehicle traveling at high speed must be able to do two things well: reduce air resistance and increase downforce. A Formula One race car is defined as much by its aerodynamics as it is by its powerful engine. This helps reduce the overall cost of the power train and enables drivers to use gear-shifting skills to gain advantage in a race.Īerodynamics. Although fully automatic transmission systems, including systems with sophisticated launch control, are possible on Formula One cars, they are now illegal. Downshifting is done on one side of the Иsteering wheel, upshifting on the other. Instead of using a traditional 'H' gate selector, drivers select gears using paddles located just behind the steering wheel. Shifting gears in a Formula One car is not the same as shifting gears in a road car with a manual transmission. ДAnd the differential is connected to the driveshaft, which transfers power to the wheels.

The gearbox is connected to a differential, a set of gears allowing the rear wheels to revolve at different speeds during cornering. Six-speed gearboxes were popular for several years, but most Formula One cars now run seven-speed units. The gearbox must have a minimum of four forward gears and a maximum of seven gears. The transmission bolts directly to the back of the engine and includes all of the parts you would expect to find in a road car - gearbox, differential and driveshaft. It's бАthe job of the transmission to transfer all of the engine's power to the rear wheels of the Formula One car. During a single season, one team will use approximately 200,000 liters (52,834 gallons) of fuel for testing and иracing.įORMULA ONE TRANSMISSIONS AND AERODYNAMICS Formula One cars, which get about four miles to the gallon, wouldn't win any awards for fuel economy. Сsport's governing body, for approval of its composition and physical properties. Each blend must be submitted to the FIA, the All in all, Formula One teams use about 50 different fuel blends, tuned for different tracks or conditions, in a typical season. The fuel that powers such an engine is not the typical unleaded gasoline you pump at the neighborhood Exxon, but it's similar. Running an engine at such high rpms produces an enormous amount of heat and puts a great deal of stress on the moving parts.
