F1 cars are very different to every other type of race car in many different ways, including in their use of a clutch. The cars are designed for high speeds and maximum performance, so this may leave you wondering if Formula 1 cars have a clutch.
F1 cars do have a clutch, but not in the same way that your manual road car has a clutch. F1 car clutches operate automatically for all gear changes during a race, but they are operated manually at the start of the race to get into first gear, and sometimes if the driver spins or needs to reverse.
If you were to sit in an F1 car, you may wonder where the clutch is, as there is no third pedal. Although this might not be a shock to drivers of an automatic car, those used to a manual may be wondering how the car has a clutch without a pedal. So, let’s go into more detail about the clutch on F1 cars.
How Does A Clutch Work?
The clutch is something that drivers of manual cars will be very aware of, but automatic cars don’t have clutch pedals, so it may be something you are unfamiliar with. We will go into the differences between the clutch mechanisms in both of these types of transmission shortly, but first let’s discuss what a clutch is.
Your car’s internals are made up of many different components. The main ones to consider here are the engine and the transmission. Of course, the engine is what drives the car, giving it power via combustion of fuel. The transmission (often referred to as the gearbox) is something you may not be as familiar with, but it is an integral part that helps to make the most of the engine’s power.
The Function Of A Car’s Gearbox
The transmission converts the energy released by the engine into mechanical drive through a system of gears. These gears rotate, and so does the shaft connected to the engine. The clutch essentially bridges the gap between the gears and the engine (drive) shaft. The basic goal of the transmission is to match the car’s road speed with the engine’s speed, for maximum performance, reliability, and fuel efficiency.
You get varying levels of torque depending on the gear you are in and your speed, and lower gears provide more torque at lower speeds, while higher gears give lower torque levels, but at higher speeds where high levels of torque isn’t as important.
This is why you start in low gears and work your way up to high gears as your speed increases. With each gear change, you disengage the clutch, removing this bridge, and while the engine keeps running you select a new gear – or in the case of an automatic car it does it for you – before engaging the clutch once again in the newly selected gear.
Key Point: Electric cars don't need clutch pedals as they don't have transmissions like combustion-powered cars do. This is because electric motors can generate a lot of torque at both low and high speeds, negating the need for gears.
Manual vs Automatic Transmissions Explained
As the name suggests, a manual transmission requires you to manually disengage the clutch in order to change gears or put the car into neutral. As you speed up, your engine speed (RPM) will increase, and you will start to run out of torque if you don’t shift up through your gears. Likewise, if you don’t shift down when slowing down, you will run the risk of stalling.
If you want to stop completely, you will disengage the clutch and then put the car into neutral (or you will keep your foot pressed down until you want to move again, but this is generally not advised as it may cause excessive wear on the clutch). In this case, you are manually breaking the connection between your engine and your transmission.
In an automatic car, there is still a clutch system, just without the pedal and the need for the input from the driver. The clutch system in an automatic is usually made up of several clutch plates that work to change the gears in combination with what is known as a torque converter. It basically multiplies the torque from the engine to prevent the car from stalling at low RPMs.
Automatic cars may also feature double clutch mechanisms. This is when the transmission has two clutch shafts: one for the odd gears and one for the even gears. This makes for very fast and smooth gear changes, as before one clutch is disengaged the next one engages, ready to take over when the first is released.
This means there is almost no loss in power due to slippage of a torque converter, and it helps to prevent excessive wear of other internal components too. This makes dual clutch systems very popular for automatic transmissions. However, they are not used in F1 cars, as they instead use a very unique clutch mechanism that is even more efficient.
KEY POINTS• Manual and automatic cars both contain clutches
• These work as a connection between the engine and the gears
• The clutch in a manual car is disengaged using a pedal, but it’s controlled by a computer in an automatic car
Do F1 Cars Have Clutches?
F1 cars do have clutches. It is a single clutch, usually made out of carbon. The whole thing weighs about 1.5 kg, with a normal clutch system weighing upwards of 50 kg in some cases. Weight saving is critical in F1, where there is so much performance to be gained by simply cutting down the weight.
F1 cars are not traditional automatics, as they are more like semi-automatics. The driver operates the gears using two paddles behind the steering wheel, which you will find on plenty of road cars as well. There is a paddle that functions as a manual clutch, but only when the driver is moving from a complete stop, and then he won’t use the clutch manually again.
Note: Drivers used to be able to use two clutch paddles to find their perfect launch bite point, but this was banned in the late 2010s
Do F1 Cars Have A Clutch Pedal?
F1 cars do not have a clutch pedal. While some F1 cars in the past did have a dedicated clutch pedal, modern Formula 1 cars instead have clutch paddles behind the steering wheel, which the driver uses at the race start and when in the pits, and sometimes when they need to engage reverse.
The car will also not automatically change gear for the driver, so he must do so using the (gear shifter) paddles every time. This is where the unique clutch of an F1 car comes in. As performance is everything, and the driver always wants to have access to maximum power, the clutch used in F1 cars is part of a seamless-shift gearbox.
This allows for very rapid gear shifts, with no loss in power through clutch slippage. Similar to the dual clutch system found in some automatic cars, it basically makes the transitions as fast as possible through the use of multiple clutch plates (although it’s even faster than a dual clutch). So, although F1 cars don’t have a clutch pedal, they do still have a clutch system.
Did Old F1 Cars Have A Clutch?
Many old F1 cars did have a clutch, especially those that used a fully manual gearbox. However, these have not been in use since the 1990s, and no modern Formula 1 cars have a clutch pedal, and instead they have clutch paddles, which are located on the back of the steering wheel.
KEY POINTS• F1 cars do have clutches
• However, they don’t have clutch pedals, and instead they have clutch paddles
• F1 gearboxes use a seamless shift system to allow for rapid gear changes
All cars with a gearbox have a clutch, and so F1 cars also have them. However, the clutch system in an F1 car is very different to the ones you will find in your own car, and most race cars for that matter. With a seamless shift, semi-automatic transmission, the clutch in an F1 car allows the drivers to get maximum power in every gear, for maximum performance.
