As electric vehicles gain popularity, it’s important to understand the number of pedals that are in use. A one-pedal driving technique is used in many models. The two-pedal driving method simply isn’t necessary with regenerative braking systems.
Here’s the Number of Pedals in an Electric Car:
Electric cars have two pedals, but only one is generally used. The acceleration pedal is used to move forward. Releasing it allows the vehicle to slow and come to a stop. The hydraulic brake pedal is only used in extreme instances when the vehicle needs to make a hard stop.

Do All Electric Cars Have Only Two Pedals?
All electric cars with an automatic transmission have two pedals. This is the acceleration pedal and the brake pedal.
The acceleration pedal is the pedal on the right that would typically be known as the gas. Since the EV doesn’t take gas, it is no longer referred to as the gas pedal.
There’s a common misconception that some EVs have only one pedal because of the concept known as “one-pedal driving.” Many assume that the brake pedal has been completely eliminated.
Although an electric car has two pedals, one-pedal driving is becoming more common.
There are quite a few benefits to one-pedal driving:
- Extend the maximum driving range on your battery charge
- Extend the vehicle’s brake life
- It offers convenience and a more relaxed drive
- The stopping phase is smoother when you don’t have to use hydraulic brakes
There is no hard and fast rule to say that you have to use one or two pedals when driving an EV.
Using one pedal means that you only have to keep your foot on or hovering over the accelerator pedal. The brake pedal is there for emergencies only. You’ll exert less energy, allowing you to relax and enjoy the drive.
The brake pedal can never completely go away because there are instances where you will need to employ hydraulic braking. Any time there’s an accident or an emergency, you’ll need to apply your brakes so that you can maneuver carefully in traffic.
You should never rely on regenerative braking in an emergency situation.
Do All Electric Cars Have Brake Pedals?
All EVs have brake pedals. Additionally, all EVs require some form of parking brake, which is either a pedal or hand brake that needs to be manually engaged.
Most EVs have what is known as regenerative braking. This means that a brake pedal is not necessary for driving in most instances. The brake pedal is only used in emergency instances, such as if someone cuts you off or to avoid a collision.
Regenerative braking happens when you remove your foot off of the accelerator pedal. The kinetic energy from the forward motion of the vehicle converts into electricity. This helps to charge the engine.
The magnetic resistance of the increase in the electric motor actually creates a braking force. The added friction within the drivetrain will slow your vehicle down until it comes to a complete stop.
Regenerative braking provides a smoother slowing of the vehicle. Depending on how hard you tap hydraulic brakes, it can actually cause a jerky movement forward. It can be uncomfortable for everyone in the car, and even add extra pressure from the seat belt.
A computer is responsible for the slowing of the vehicle when one-pedal driving is used.
Hydraulic brakes are installed, so you’ll have the brake pedal. Using the brake too much can result in wear and tear, service, and the need to replace parts. It can also release brake dust into the atmosphere, creating an environmental problem. As such, eliminating the brake pedal’s use as much as possible has eco-friendly benefits.
Do Electric Cars Have a Clutch Pedal?
The only way that an electric car can have a clutch pedal is if there is a manual transmission.
Almost all electric cars on the market have an automatic transmission.
Automatic transmissions are easier for people to drive. The manual transmission is on its way out because there’s enough technology that will handle gear-changing automatically.
According to a study by Edmunds, in 2020, only 41 out of the 327 car models sold in the U.S. offered a manual transmission.
Each and every year, fewer car models offer a manual transmission. Also, no Tesla models have manual gears.
Regardless of whether a vehicle is gas or electric powered, most drivers prefer an automatic transmission.
Considering that one-pedal driving is so popular, EV manufacturers don’t want to add in the third pedal (the clutch) unless it’s absolutely necessary.
There are only two electric cars currently on the market that have a clutch pedal. This is the Audi e-tron GT and the Porsche Taycan Turbo S Cross Turismo.
Even in a manual transmission electric car, there is no need to have a clutch. The reason is that the electric motor won’t stall like a gas-powered one.
Toyota has even filed a patent for an EV that simulates the feel of driving a clutch. Instead of using a clutch pedal, however, it simply offers a stick-shift and a three-mode selector.
A few prototypes are on the market that may feature a clutch pedal at some point:
- EV Mustang
- Jeep Magneto
- Tesla Model S
- Toyota bZ4X
So, the only time an EV will have a clutch is if it has a manual transmission. However, even then, it may not have the need for a clutch pedal. It all depends on the technology that goes into the individual model.
Can You Drive Electric Cars by Only Using the Gas Pedal?
You have the ability to drive your EV using only the accelerator pedal (formerly known as the gas pedal).
You can choose what you feel comfortable with. If you have always driven using two pedals, you may feel comfortable using the brake pedal.
In an EV, you can protect your brakes by avoiding the hydraulic brakes on a regular basis. Instead, you simply learn to anticipate when you need to slow down or come to a stop. Every vehicle is different.
You’ll want to “feel” the pressure of the accelerator so that you can learn how sensitive the pedal is. This way, you can ease off of it to slow down as necessary.
There’s an on/off button in most electric cars that allow you to switch to one-pedal driving mode. When you have this feature on, your brake lights will actually appear when you lift your foot off of the accelerator.
One-pedal driving will work when you are in both drive and reverse mode.
There are some tips to help you with one-pedal driving. It can take time to learn how to become less dependent on using the brake pedal.
- Use the accelerator pedal to accelerate on the road
- Lift your foot off of the accelerator pedal gradually to slow your vehicle gradually
- Lift your foot off of the accelerator abruptly to slow your vehicle faster
- Press the accelerator pedal to return to your desired speed
- Learn to gauge how long it takes for your vehicle to slow and come to a stop
Eventually, you won’t need to use the brake pedal unless there’s an emergency.
Can Electric Cars Have Something Similar to Engine-Breaking?
Electric cars utilize something similar to engine braking. The concept is different, though, because there’s an electric battery instead of gas powering the vehicle.
Engine braking is defined as removing your foot off of the accelerator and allowing the engine to downshift gears naturally. It does not involve pressing on the brake pedal. It is also not the same as coasting.
Coasting is when you push the car into neutral and simply accelerate forward without using any pedals, such as when going downhill.
When you use the brake pedal, hydraulic braking takes place.
Engine braking is actually illegal in some areas. You may see signs on country roads that read “Residential Area: Do Not Use Engine Brakes.” This is typically focused on semi-truck drivers. Engine braking can be extremely loud.
Shifting the braking from the brake pads and rotors to the engine can actually reduce maintenance costs. You won’t have to replace pads and rotors as frequently by allowing your engine to do some or all of the braking.
Your engine absorbs the energy and slows the vehicle so that your brakes aren’t the ones absorbing the friction.
Engine braking is actually fairly uncommon in cars and SUVs simply because the driver doesn’t have the capability to shift from Drive (D) to Low (L).
The reason engine braking isn’t popular is that the back pressure in the engine can be extremely dangerous (and loud).
Regenerative braking in an EV is the primary way to stop, as opposed to relying on the hydraulic brake pedal.
Additionally, regenerative braking won’t create pressure, causing damage to the engine. Instead, the regenerative braking slows the EV down and recharges the battery, providing two critical benefits.
