Formula One (F1) race cars are single-seat, open-wheel racing vehicles with the engine positioned right behind the driver. Like most cars they make use of internal combustion engines and are equipped with usual elements such as brakes, wheels, transmissions, and suspensions. However, these cars are not designed or intended for casual driving. All of their elements are tweaked and designed for speed only. It’s quite easy for an F1 car to attain a speed of 200 mph. But, during the race itself, the speeds are typically lower.
These cars are governed by the Fédération-Internationale de l’Automobile (FIA) regulations, which are unique to the Formula One Championship. Such regulations specify that racing cars must be built by the participating teams themselves. However, participants are permitted to outsouce the cars’ manufacture and design.
Components Making up F1 Racing Cars
There are many things about F1 racing vehicles that people are curious about or simply unaware of. Below, we delve into the major systems employed in F1 racing cars.
The chassis is the heart of Formula One cars. It’s the part onto which virtually all elements are bolted and attached. As it’s with most modern vehicles, F1 cars feature a monocoque (single-shell) construction. The term ‘single-shell’ implies the process of constructing a car’s whole body out of only one piece of material.
Sometime back, this material was commonly aluminum. Today, they’re usually constructed out of strong composite, like carbon-fiber layered on an aluminum mesh or spun carbon-fiber set in resin. Such allow for development of lightweight cars which can hold up well against the enormous, downward forces produced as the vehicles move through the air.
The build incorporates a sturdy, padded cell (cockpit) which accommodates one driver. Contrary to cockpits built for road-ready vehicles, the cockpits of F1 cars are required to adhere to the set rigorous technical regulations.
For instance, a Formula One car must sport a flat floor, in addition to meeting minimum size requirements. The minimum permissible weight is set at 1,605 pounds, inclusive of the driver and exclusive of the fuel. However, the seat is specially constructed to fit the driver’s precise measurements. That limits his movement as the race car moves all around the track.
Aerodynamics are a vital key to succeeding in F1 racing. Teams spend million of dollars in this field. As a general rule, any vehicle that travels at high speeds must have the ability to increase downforce and reduce air resistance. F1 cars are often wide and low to elp decrease air resistance. The barge boards, wings, and end plates help increase downforce.
Formula One cars bear wings which operate on similar principes as airplane wings, but now in reverse. While airplane wings help create lift, F1 cars’ wings produce downforce, thus holding the vehicle onto the track. The driver can fine-tune and adjust the angle of both wings to achieve a suitable balance between downforce and air resistance.
Back in the 1970s, Lotus engineers discovered that it was possible to turn a Formula One car into a giant wing. As such, they adopted a unique undercarriage model which enabled them to extract air from the car’s bottom. In turn, that created a low-pressure area which sucked the entire car downward. However, such ‘ground-effect’ forces were outlawed. Strict regulations to govern the undercarriage design were subsequently put in place.
Today, the car’s bottom is expected to be flat. Engineers can then execute their ideas beyond the car’s rear axle line. Most of them incorporate a diffuser, which is an upward-sweeping unit located right below the gearbox and engine. A suction effect is created by the diffuser as air is funneled up, passing it to the car’s rear side.
Endplates are flanged areas along the front wings’ edges. These ‘grab’ the air before directing it along the car’s sides. The barge boards, on the other hand, are located right behind the car’s front wheels. Upon picking up the air, they accelerate it to provide for even more downforce.
Earlier, F1 race cars were powered by 3-liter, V10 engines. Today, the rules require that the cars use 2.4-liter, V8 engines. Sure, the power outputs fell with the revision of the rules. But, F1 engines are still capable of producing almost 900 horsepower.
A Formula 1 race car’s engine will prompt for a rebuilding after a relatively few miles. That’s because the engine is required to run at quite high revolution rates (almost 19,000 rpm) to generate such substantial amounts of power. Running a car’s engine at very high rpms leads to production of enormous amounts of heat, thus putting a significant deal of stress on all the moving parts.
Such engines are powered by small amounts of non-hydrocarbon compounds. Most power-boosting additives aren’t allowed. In typical seasons, F1 teams make use of nearly 50 distinct fuel blends which are tuned for specific tracks and conditions. These blends are submitted to the sports’ governing body (FIA) for approval of their physical properties and composition.
The suspension incorporated in Formula One cars features the same components you’d find in a road car’s suspension. Such include dampers, arms, dampers, and anti-sway bars. Nearly all Formula 1 race cars are equipped with double wishbone suspensions.
Prior to the actual race, participating teams tweak the suspension settings to ascertain that their car can corner safely and brake, yet deliver responsiveness when it comes to handling.
It’s included to help transfer the power of the engine to the F1 car’s rear wheels. The transmission, bolting directly to the engine’s back, includes all the parts you’d find in a typical road car, including the gearbox and driveshaft. The gearbox is required to have 7 or less gears and at least 4 forward gears. Nowadays, most Formula 1 race cars run 7-speed units.
The rear wheels are able to revolve at various speeds during cornering, thanks to the incorporation of a differential. The gearbox connects to the differential, which further connects to the driveshaft. This shaft is responsible for power transfer to the wheels. Drivers shift gears using the paddles situated right behind the car’s steering wheel.
While fully-automatic transmission systems are possible on Formula 1 race cars, they’re illegal. In turn, that helps reduce the powertrain’s overall cost. Additionally, drivers are able to gain advantage by using their gear-shifting skills.
VI. Steering Wheel
The F1 car’s steering wheel bears little resemblance to that found in road cars. As the main command center, this wheel houses an array of buttons, switches, and toggles.
With just a single tap, the driver can operate and control nearly all aspects of the vehicle’s performance, including brake balance, gear changes, and fuel mixture. Data such as speed, engine rpm, and lap times are displayed on the integrated LCD screen. Furthermore, the driver gets all that control from a wheel that’s almost half the size of a road car’s steering wheel.
The driver is expected to get out of the car within 5 seconds, removing the steering wheel only. To achieve that, the wheel is attached to the car’s steering column using a snap-on connector.
The brakes employed here must be able to stop a car that’s traveling at speeds of over 200 mph. The brakes, in turn, glow red-hot when they’re used. Thankfully, most teams now use carbon fiber pads and discs to help reduce any wear and tear, in addition to increasing the braking performance.
Such brake systems, despite being lightweight, have proven to be greatly effective at temperatures of up to 1,800 degrees Fahrenheit (1,000 degrees Celsius). The holes along the brake disc’s edge allow for rapid heat escape, too. Most cars also feature air intakes on the outside of their wheel hubs. These help cool down the braking system.
These are the only elements touching the track’s surface. That explains why they’re among the most important parts of Formula One race cars. All other major systems (suspension, braking, and engine) perform their tasks by way of the car’s tires. In case the tires don’t perform well, the cars won’t perform well, irrespective of other systems’ technical superiority.
Just as it is with other parts of Formula One cars, the tires are considerably regulated. Today, the FIA demands that the front and rear tires be 12-15 inches wide and 14-15 inches wide respectively. Aside from that, 4 continuous, longitudinal grooves ought to run around the tires’ circumference. These ought to be at least 0.098 inches deep and 1.97 inches apart.
F1 tires are generally made from soft rubber compounds. As these compounds heat up, the tires are able to adhere to the track and offer enormous gripping power. As a matter of fact, racing tires tend to perform best in high temperature levels. The tradeoff, in this case, is decreased durability. Formula One tires are built to last for up to an estimated 125 miles.
F1 Car Racing
Formula One racing is a unique and hugely popular sport. Among the things that set it apart from virtually all other racing sports and competitions are the stringent rules and regulations that drivers are required to adhere to.
There are multiple set regulations regarding the track’s design, the race’s rules, and the constructions of cars participating in the racing events. The engineers behind these race cars adopt an aerodynamic design, ensuring they’re extremely fast, but safe.
This sport undeniably takes car racing to an all-new level. And, while F1 racing is a fantastic sport, one must pay close attention to all details. Quite a lot of effort goes into constructing and designing these cars, as well as ensuring they’re well-equipped for the actual race events, performance- and safety- wise. And, such are among the things that make this sport a favorite for many people from all corners of the globe. In fact, F1 racing will only continue to develop and grow even more popular. It’s as much of a joy to watch as it is to participate in.
