Electric cars have been in existence since 1835. This is quite a long time, but you can’t compare them with today’s electric bike speed, not to talk of conventional cars.
However, in the last two decades, we started seeing electric cars with futuristic sleek designs, deadly horsepower, and torques.
Electric cars are making big waves in the automobile industry. These pollution-free, noiseless, and high-performance cars are expected to outdate their internal combustion engine rivals by 2025.
Tesla has been at the forefront of manufacturing futuristic electric cars since its inception in 2003. But how do electric cars work?
Does Tesla have an engine? How does a Tesla engine work? We’ll explain these and more in this article. But first, let’s see if Tesla cars truly have engines.
What is a Tesla?
A Tesla is an electric vehicle that runs on batteries and an electric motor instead of an internal combustion engine.
This means that Tesla vehicles rely on renewable energy sources and produce zero emissions, making them a cleaner, more sustainable option for transportation.
Tesla vehicles are equipped with advanced features such as autopilot, which allows the car to drive itself on highways and navigate through traffic.
Tesla are also known for their impressive acceleration, with some models capable of accelerating from 0 to 60 mph in under 2 seconds.
Does Tesla Have An Engine?
The way Tesla builds their cars is mind-blowing. When you open the hood, you’ll ask yourself, where is the engine? If you have a Model 3, you may ask, where is the engine in the Tesla Model 3? Or do they have an engine?
The simple answer is no. Tesla does not have internal combustion engines (ICE). Instead, they have electric motors that use rechargeable batteries.
On rear-wheel-drive Tesla, the manufacturers place the electric motor on the rear axle. Similarly, Tesla manufacturers place electric motors on the front and rear axles on all-wheel-drive models.
As I mentioned earlier, these electric motors work with rechargeable batteries. Therefore, you need to recharge the battery from time to time instead of buying gasoline or diesel in a gas station.
You can plug your electric car into a standard outlet or install a wall charger for a much quicker charge.
Tesla manufacturers built their cars like average vehicles on the road. However, they use a different configuration.
How Does A Tesla Engine/Motor Work?
Tesla does not use an internal combustion engine or any typical powertrain components. There is no transmission or drivetrain to the separate axles. EVs instead rely on an induction motor powered by rechargeable batteries to directly power axles or wheels.
Tesla models vary in the number of motors they use. Rear-wheel drive Teslas have a single electric motor connected to the rear axle, while dual-motors use a front axle motor and a rear axle motor.
Tri-motor versions, as in the Model S Plaid and Model X Plaid, have three motors, one for each rear wheel and one for the front axle.
Taking the gas engine, transmission, driveshaft, and other mechanical pieces out of the equation means that Tesla’s electric motor offers a vastly superior power-to-weight ratio. It does this thanks to its infinite torque, capable of running from 0–18,000 RPMs.
Without the full range of rotational speeds, the electric motor would have the same limitations as an ICE.
You can’t attach an ICE directly to the axle because it has a narrow RPM range, often around 1,000–6,000 RPMs.
It needs several gear configurations in a transmission to translate these limited RPMs into a broader range of speeds, say 0–120 mph. That’s why you’ll come closer to redlining while accelerating before dropping RPMs as the transmission shifts up a gear.
Since Tesla’s motors don’t require these gear changes, the power can attach directly to the wheels, cutting weight and providing seamless acceleration. The only bridge is a small, single-speed transmission from the motor to the axle.
Where is the Tesla Engine?
If you’ve ever looked under the hood of a Tesla, you know that there’s no engine underneath. Additionally, you aren’t going to hear the traditional sounds of a combustion engine.
With a gas- or diesel-powered motor, you hear plenty of noise and you know there’s an engine running, but that’s not the case with Tesla EVs.
Under the hood of the Tesla, you find additional cargo space, because there’s no engine to make room for. While the Tesla car won’t have a gas-powered engine, it is powered by one or more electric motors that are powered by rechargeable batteries.
There is a motor located on each axle that’s being powered. If you own a rear-wheel drive Tesla, the motor sits on the rear axle, so it can power it.
Front-wheel-drive models have one on the front axle. Additionally, the all-wheel-drive Tesla contains a motor on both axles to power all of the wheels.

Key Components
Induction Motor
The induction motor consists of two components: the rotor and the stator. The rotor comprises conducting bars. The bars are typically short-circuited at each edge.
The stator has a three-phase AC power input in the coil. This produces a rotating magnetic field. The induction motor in Tesla generates a four-pole magnetic field. This RMF then induces the electric flow on the rotor bars to enable it to turn.
The rotor in the inductor motor lags the rotational magnetic field. Therefore, the induction motor does not have a permanent magnetic field or brushes.
Notwithstanding, it is powerful and robust. The primary advantage of an induction motor is that the speed correlates with the alternating current power supply.
So, by just deferring the frequency of the alternating current supply, you’ll increase or decrease the vehicle speed. This technology enhances Tesla and other electric cars’ speed and makes them reliable and easy to control.
The induction motor speed ranges from 0 to 18,000 RPM. This is one of the futuristic advantages of electric cars over conventional gasoline-powered and diesel-powered engines.
There is no doubt that ICE-powered vehicles produce usable horsepower and torque, but it comes only within a limited speed range. But where does the induction motor receive power?
The battery pack
The battery pack produces all usable power for the induction motor. The battery generates direct current, but the DC electric flow has to be converted to alternating current. And that’s where the inverter comes into play. (We’ll get to that in a moment).
Tesla manufactures their battery pack with small lithium-Ion cells like those in your cell phones and laptops. They connect these small lithium-Ion cells in parallel and series to generate the required power to handle all system operations.
Tesla also installs a Glycol coolant that runs via some inner metallic tubes among the gaps on these small battery cells to prevent them from overheating.
Using several small cells Instead of a few big cells guarantees efficient cooling. And this helps to extend the battery lifespan.
The manufacturers place the small cells in modules. There are around 16 modules in most Tesla cars, which consist of 7,000 small lithium-Ion battery cells.
The inverter
The inverter controls the alternating current frequency, controlling the induction motor speed. In addition, the inverter can even defer the amplitude of the alternating current.
This means the inverter can control the motor output. By this, the inverters work as the mastermind of Tesla and other electric cars.
When the Glycol coolant absorbs heat, it returns to the radiator in front of the car to cool it down.
The drivetrain
Let’s have Tesla drivetrains explained and examine how it work with the Tesla engine – technically, Tesla electric motor.
The Tesla motor sends the generated power to the wheels via a transmission. It’s essential to note that Tesla transmission uses a single-speed transmission algorithm. This is quite different from a conventional transmission.
Advantages of a Tesla
Tesla electric cars offer several advantages, making them a popular choice among drivers. Below are some of the top benefits of owning a Tesla:
Impressive battery range
Tesla vehicles are known for their long-lasting battery life, which makes them ideal for daily commuting and driving around town. Battery range is rarely an issue, particularly for short-distance travel.
Cost-effective charging options
Charging a Tesla at home is significantly less expensive than filling up a gas tank. On average, it costs around $23 USD to charge a Tesla for a distance of 500 miles, compared to the $50 USD it would cost for gasoline.
Reliable charging network
One of the major concerns for electric car owners is access to charging stations. Tesla has an extensive network of charging stations that have grown as electric cars have become more popular.
Tesla’s charging network is widely available, making it a dependable option for accessing high-quality charging stations.
S&P Global Mobility estimates that there are currently around 16,822 Tesla Superchargers and Tesla destination chargers in the US.
Ideal for car-sharing services
Tesla is often a popular choice for people who want to make a statement with their vehicle. However, the high price tag can make purchasing a Tesla outright unaffordable for many people.
Car subscription services offer a pay-per-month option that allows anyone to have access to a Tesla without the high upfront cost. This makes Tesla an excellent choice for car-sharing businesses.
FAQs.
Q: What can of Motors are in Tesla?
Tesla uses alternating current (AC) and direct current (DC) motors to produce their cars. For instance, Tesla uses an alternating current (AC) induction motor in model S., but in model 3, they utilize permanent-magnet direct current (DC) induction motors. Both the AC and DC induction motors have their advantages and disadvantages.
Q: Where is the motor in the Tesla?
You may be wondering, how many motors does a Tesla have? Tesla manufacturers place the induction motor in the rear and front axle depending on the wheel drive you have.
For example, on a rear-wheel drive, the motor is placed on the rear axle, and the induction motor is placed on the front and rear axles on the all-wheel drive.
Q: Is Tesla powered by gas?
No, Tesla does not run on gas. They run on 100% electricity and will probably never run on gasoline.
Tesla will always be all-electric cars because they trust their technology and will not want to devolve the quality of their system or mitigate to hybrid or gasoline technology.
Q: Does Tesla have transmissions?
There’s a lot of misconception and uncertainty regarding how Tesla transmits power to the wheels. If you’re asking, does a Tesla have a transmission?
The answer is a bit tricky. In any case, Tesla has single-speed transmissions. This means they have one gear and, of course, do not need more than that.
However, the single-speed transmission does not work like the ones on internal combustion engines, where you need to shift from lower to higher gear and vice versa.
Q: How fast can a Tesla go?
Among many claims, Tesla said the Roadster is the fastest car in the world. For example, the Tesla Roadster covers 0-60 mph in 1.9 seconds. The company also said the car has a top speed of 250 mph and a range of 620 miles.
However, Tesla is not the fastest car on the road. In fact, most Bugatti are faster than Tesla Roadster in top speed, but the Roadster has a better acceleration time than most Bugatti.
Q: Does Tesla need water?
According to a report by Blomberg, Tesla uses around 3,000 liters of water for every car they manufacture. This is quite high, but brands like Volkswagen and Mercedes-Benz take roughly 3,700 and 4,700 liters, respectively.
Q: Is Tesla good for cold weather?
If you live in a cold-weather environment, you don’t need to worry if Tesla is the right brand. Tesla has cold-weather environments in mind.
Tesla has several features designated to keep you safe in cold weather. First, however, you have to find out how to use these cold-weather features.
Q: Does Tesla have brakes?
All Tesla models come with high-performance Brembo emergency and automatic braking functions.
Tesla uses disc brakes like every other vehicle on the road. However, the brakes do not wear like the ones on your traditional cars. In addition, the brake pads on Tesla models can last half of the lifespan of the car.
Q: Does Tesla have a spare tire?
All Tesla models do not have a spare tire. Instead of installing a spare tire, Tesla focuses on creating maximum interior space and a large amount of cargo space.
However, I think the primary reason Tesla does not install a spare tire is that research shows that Tesla owners will hardly or never make use of the spare tire throughout the lifespan of the car.
Final Word
The subject ‘Does Tesla have an engine’ is a prevalent topic on many automotive forums. If you have popped up a Tesla hood, you’ll ask, ‘Where is the Tesla engine?’
Tesla does not have traditional gasoline-powered or diesel-powered engines. Instead, they use an induction motor, which serves as the engine.
It’s crucial to note that most car enthusiasts refer to the induction motor as an engine. So, don’t get confused when you hear electric car motor and electric car engine.
We’ve provided all you need to know about electric car motors and how they work. You can refer this article to anyone still contemplating if Tesla cars have engines.
