Electric cars use batteries to power the vehicle, instead of an engine and other moving components. This leads one to wonder just how many moving parts electric cars use, compared to a combustion-powered car. 

Electric cars use around twenty moving parts, with the exact number differing between each make and model. Nevertheless, electric cars use less than internal combustion engine cars, which use about 2000 moving parts.

In this article, I’ll list and explain all the moving parts used in electric cars. I’ll also explore the advantages of using fewer moving parts, why some parts are omitted from electric cars, and more. 

How Many Moving Parts in a Tesla Engine? 

Generally speaking, electric cars have about 20 moving parts included in the vehicle. However, this varies depending on the manufacturer. So what about tesla? How many moving parts does Tesla use in their electric car engines? 

Seventeen moving parts are typically used in a Tesla engine, which is slightly below average for an electric car engine. Although, some models do use more in their design. Still, Tesla has about 90% fewer moving parts than traditional engines. 

What are Electric Vehicles?

Electric vehicles, or EVs, are cars that run on electricity instead of gasoline or diesel fuel. They use a rechargeable battery pack to power an electric motor which propels the car forward.

Electric vehicles have significantly fewer moving parts compared to Internal Combustion Engine (ICE) cars.

ICE cars require a complex system of components including pistons, cylinders, valves, spark plugs, and exhaust systems to operate.

In contrast, electric motors have only one moving part – the rotor – and require no transmission or gears.

Additionally, EVs have regenerative braking systems which help extend brake life since most of the stopping power comes from regenerating energy back into the battery rather than using traditional friction brakes like in ICE cars.

How Many Moving Parts do Electric Cars Use?

Unlike traditional vehicles that require hundreds, if not thousands of parts to function properly, electric vehicles are relatively simple in design.

The main components of an electric vehicle include the motor, batteries, and controller. In contrast, traditional cars have many more moving parts such as the engine, transmission system, exhaust system, fuel tank and more.

What Are the Benefits of Less Moving Parts in a Car? 

Electric cars have roughly one moving part for every hundred moving pieces used in internal combustion engines. This comes with some significant advantages.

The main benefit of having fewer moving parts in a car is that less maintenance is required for the car to function. Fewer moving parts also means fewer potential problems can arise as fewer things go wrong. Fewer moving parts also make repairs more manageable and less complicated. 

The reduction in moving parts also makes for a smoother and quieter ride.

How Many Moving Parts Do Electric Cars Use
Electric cars are innovative and efficient modern means of transport. Electric cars are less complicated than internal combustion engines and contain fewer moving parts. Electric cars only have about 20 moving pieces throughout the vehicle, considerably less than traditional cars.

Do electric cars require less maintenance than traditional cars?

Electric cars require less regular maintenance than traditional internal combustion engine cars. This is because a high amount of the maintenance involved in keeping cars is targeted at moving parts like transmissions or pistons that are not present in electric cars. 

When there are more minor moving parts used in anything, there are fewer ways things can go wrong. As a result, your electric car will be less vulnerable to mechanical issues than traditional gas-powered cars. 

Since there are fewer potential issues with electric cars, repair work is generally more accessible and straightforward than gas cars.

With ICE vehicles, replacing a single component can often mean disassembling half the engine block or transmission system.

As a result, repair work on evs can be completed quicker and is easier for the mechanics, which will reduce labor costs and the overall cost of your repair. 

Remember that, because EVs are still relatively new, not all mechanics are able to repair them. You might have to pay additional money for a mechanic that specializes in electric vehicle motors.

What Makes Electric Vehicles Environmentally Friendly?

Since electric vehicles run on electricity instead of gasoline or diesel fuel, there are no emissions from the tailpipe. This not only improves air quality but also reduces our dependence on fossil fuels, which contribute to climate change.

Additionally, many EV owners choose to power their vehicles with renewable energy sources such as solar panels or wind turbines, further reducing their carbon footprint and promoting sustainable energy practices.

With fewer moving parts to break down or wear out, EVs like Teslas are not only better for the environment but also more cost-effective in the long run.

Traditional automotive retailing relies heavily on selling replacement parts and services for ICE vehicles, which can add up to significant costs over time.

Do Electric Cars Use Transmissions? 

Electric cars lack a large portion of the parts that traditional cars use. I’ve already covered this in detail. However, I’m yet to discuss which pieces you are accustomed to are missing from electric vehicles. One part that people often wonder about is transmissions, and are they used in electric vehicles? 

Electric cars typically don’t use transmissions. Rather, electric cars operate in one gear and can thus accelerate or decelerate without using transmission to shift gears. A few electric cars do contain a transmission, though this is rare. 

Since electric cars lack a transmission, they also don’t have a reverse gear. Instead, the electric engine reverses the direction it spins, allowing the car to go backward. When cars have only one gear, it means that you don’t have to worry about damages occurring to gears or the clutch, which are common issues in gas or diesel cars.

Which ICE Engine Parts Are Not Found In EVs?

Electric vehicles have, in some cases, thousands of fewer parts than internal combustion engines. Parts missing from EV engines include spark plugs, fuel filters and timing belts.

EVs are much simpler in their design and require less frequent service appointments. This means that owners can save time and money on routine maintenance while enjoying a quieter and smoother ride.

What is the average lifespan of an electric car motor?

The lifespan of an electric car motor varies, but typically lasts longer than a traditional combustion engine due to its simpler design and fewer components that can wear out over time. Many manufacturers claim that the motor itself can last up to 15 years or more with proper maintenance.

This is great news for those who are looking to invest in an electric vehicle for long-term energy savings and reduced emissions. It’s important to note, however, that other parts of the electric car may still require maintenance or replacement over time.

For example, the battery pack will eventually need to be replaced after several years of use.

But overall, the simplified design of the electric motor means fewer moving parts and less wear and tear on the vehicle as a whole.

As automotive retailing continues to shift towards cleaner energy options, it’s likely we’ll see more advancements in electric motor technology that make them even more efficient and durable in the future.

Do Electric Cars Use Engine Oil? 

Electric cars are powered with batteries instead of traditional internal combustion engines, which use flammable liquids like gas. The mechanisms involved in combustion engines are more complex, with ten times as many moving parts involved. As a result, engine oil is required, but what about electric cars?

Electric cars don’t use engine oil, but rather engine lubricants. Unlike oil, lubricants don’t require a bi-monthly refill, as electric cars don’t utilize combustion and have fewer moving parts. This can result in significant savings over a few years on maintenance and materials.

If you have ever owned a gas car that consumes a lot of engine oil, you’ll know how expensive engine oil can be over time. Although, if you own an electric car, you won’t have to invest in this regular maintenance as it’s not necessary. 

Can I Service My Own Tesla Engine?

If you’re a Tesla owner, it’s important to know that servicing your own engine is not recommended and can actually void your warranty. I recommend always taking your Tesla to a certified mechanic for electric vehicles if you experience troubles with your engine.

That being said, while servicing your own Tesla engine is not recommended, there are still some things you can do yourself to keep your car running smoothly. For example, keeping the tires properly inflated and checking the brake pads regularly are both easy tasks that anyone can do at home.

However, for more complex issues like battery health or engine troubles, it’s best to leave it to the professionals at a Tesla service center who have been trained specifically for these types of repairs.

By doing so, you’ll ensure that your car stays in top condition and continues to provide you with years of reliable transportation.

Are insurance premiums for electric cars higher than traditional cars?

You might be inclined to think that, because electric vehicles require less maintenance and have fewer parts, insuring them is cheaper than traditional cars.

However, insurance premiums for EVs may be more expensive than those for traditional vehicles because the cars are still more expensive. Of course, this can vary depending on the specific make and model.

Insurance providers consider electric cars to be a new technology with unknown risks which can result in higher premiums. Additionally, EVs often require specialized maintenance services and technicians that are not readily available at every automotive retailing location. This can increase repair costs, raising insurance premiums.

Remember that Tesla offers free roadside assistance though, which might be a reason to go for Tesla rather than other EV brands.

However, it’s important to note that some insurers offer discounts or special rates for electric cars due to their lower energy consumption and emissions. In fact, studies have shown that EV drivers tend to have fewer accidents than traditional car drivers which could lead to potential discounts in the future.

As the popularity of electric cars grows, it is expected that insurance providers will become more familiar with these vehicles leading to a reduction in rates over time.

Overall, while there may currently be some differences between insuring an ICE vehicle versus an EV, it’s important for consumers to shop around and compare policies before making a decision.

Insurance for Teslas

You’re a Tesla owner, and finding the right insurance policy is crucial to protect your investment and give you peace of mind while driving.

With electric cars being relatively new in the market, it’s important to find an insurance company that understands the unique aspects of these vehicles.

Teslas, for instance, have fewer moving parts than traditional internal combustion engine (ICE) cars, which means they are generally less prone to mechanical failures. However, this does not mean that Teslas are immune to accidents or damage.

In fact, their high-tech features and expensive components can make repairs more costly than those for ICE cars. This is why it’s essential to find an insurance policy that covers everything from collisions to theft and vandalism.

Some companies even offer specific policies tailored for electric cars like Teslas, which provide additional coverage for things like charging station fees and battery replacement costs.

As a Tesla owner, having comprehensive insurance coverage will not only give you peace of mind but also ensure that your investment is protected in case of any unexpected incidents on the road.

Will All Cars Be Electric in the Future?

Electric cars still make up a minority of the new cars sold every year, yet many see them as full of potential. Every year the sales of these vehicles increase, with most major car manufacturers now offering them. 

It’s expected that 20% of all sales will be electric cars in the future. This global estimate is for 2050 and could be even higher as states worldwide are starting to phase out internal combustion engine cars to comply with climate change policies.

Japan, China, Britain, and some European countries have committed to stopping the sale of internal combustion engine cars within the next twenty years. This will surely increase electric cars’ market share as their biggest competition slowly becomes illegal in the future.
