You’ve seen them zooming silently past you at a green light. They look like cars, they drive like cars, and they’ve definitely got plenty of zip. But if you pop the hood on a Model 3 or a Cybertruck, you aren't going to find a greasy block of metal with pistons and spark plugs.
So, honestly, do Teslas have engines?

Basically, no. They don't. Not in the way we've been taught to think about cars for the last hundred years. If you’re looking for a combustion-based machine that burns fuel to create a series of controlled explosions, you’re looking in the wrong place. Teslas use electric motors.
It sounds like a small vocabulary tweak, right? Motor versus engine. But the difference is actually massive. It changes everything from how the car feels when you floor it to why you never have to stand in a rainy gas station ever again.
Why people still ask if Teslas have engines
It’s a fair question. We call the thing under the hood an "engine bay." We talk about "engine oil." The word is baked into our brains.
In a traditional car, an internal combustion engine (ICE) is a complex beast. It has thousands of moving parts. You’ve got valves, timing belts, fuel injectors, and a cooling system that’s constantly fighting to keep the whole thing from melting. It’s loud, it vibrates, and it gets really hot.
Tesla threw that entire playbook in the trash.
Instead of an engine, a Tesla has a "drive unit." This is a compact, sealed housing that contains an electric motor, an inverter, and a single-speed transmission. While a gas engine might have 200+ moving parts, a Tesla motor has about 20. It's basically a rotor spinning inside a magnetic field.
Simple. Elegant. And way more reliable.
The "Frunk" factor and where the power lives
One of the funniest things for first-time Tesla owners is opening the hood. Usually, you expect to see a mess of hoses and wires. Instead, you get... a trunk.
Because there is no bulky engine block, Tesla designers realized they had a bunch of empty space up front. They call it the frunk. You can put your groceries there, or a small suitcase, or—as many people do for the "gram"—a large pizza.
If the motor isn't under the hood, then where is it?
In a Tesla, the motors are tucked away between the wheels, usually on the axles. If you have a Rear-Wheel Drive (RWD) Model 3, there’s one motor in the back. If you have an All-Wheel Drive (AWD) model, there’s one in the front and one in the back. The "Plaid" versions of the Model S and Model X even have three motors.
The weight is kept low and centered, which is why these cars handle like they’re glued to the road. The "engine" isn't a heavy lump sitting high up in the front; the power is distributed right where it’s needed.
Motors vs. Engines: The technical breakdown
Technically, an "engine" is a machine that converts a fuel (like gasoline or steam) into motion. A "motor" converts a pre-processed energy (like electricity) into motion.
- Fueling: Engines burn gas. Motors use electrons.
- Torque: A gas engine has to "rev up" to reach its peak power. A Tesla motor gives you 100% of its torque the millisecond you touch the pedal.
- Efficiency: Most gas engines are about 20% to 30% efficient—the rest of the energy is wasted as heat and sound. Tesla motors are over 90% efficient.
No oil changes? Really?
This is where it gets good. Since there’s no internal combustion engine, there’s no engine oil. You will never, ever have to go to a Jiffy Lube again.
You also don't have:
- Spark plugs
- Mufflers or exhaust pipes
- Alternators
- Starter motors
- Timing belts
Honestly, the maintenance list for a Tesla is kind of hilarious. You mostly just need to worry about tires, windshield wiper fluid, and the cabin air filter. Since Teslas use regenerative braking—where the motor spins backward to slow the car and charge the battery—you barely even use your actual brake pads. Some owners go 100,000 miles before even thinking about a brake job.
What about the "engine" noise?
If you miss the roar of a V8, you’re out of luck. Tesla motors are nearly silent. At low speeds, they actually emit a synthetic "pedestrian warning sound" through an external speaker just so people know a car is coming.
Elon Musk has often joked that internal combustion cars will eventually look like steam engines—relics of a different era. Whether you agree or not, the engineering shift is undeniable. By replacing the engine with a motor, Tesla simplified the car.
Actionable insights for the curious
If you are thinking about making the switch or just trying to win an argument at a dinner party, keep these facts in your back pocket:
- Check the Frunk: If you’re looking at a used Tesla, check the front trunk for signs of weather-strip wear. It’s one of the few moving "body" parts up there.
- Weight Matters: Remember that while there's no "engine," the battery pack in the floor is heavy. This means you’ll need tires specifically rated for EVs (extra load) because they wear down faster than on a Honda Civic.
- Winter Range: Unlike a gas engine that creates "free" heat for the cabin, a Tesla motor is so efficient it doesn't get hot. In older models, this meant the heater drained the battery fast. Newer Teslas use a heat pump to stay warm without killing your range.
The bottom line? Teslas don't have engines, they have something better: a simplified, high-performance propulsion system that makes the "vroom vroom" era feel a little bit like ancient history.
To keep your Tesla (or future Tesla) running perfectly, focus on tire rotations every 6,250 miles and swapping your cabin filters every two years. That’s about as "mechanical" as it gets.
