What You'll Learn
Electric vehicles require less maintenance than conventional vehicles
Electric vehicles (EVs) generally require less maintenance than conventional vehicles. This is due to the fact that they have fewer moving parts, which means less wear and tear on components. Unlike internal combustion engines, electric vehicles do not have oil that needs to be changed, no gaskets to replace, and no valves to clog up. As a result, electric car owners can save thousands in maintenance costs compared to conventional car owners.
While EVs may have higher upfront costs, they make up for it in the long run with reduced maintenance expenses. A Consumer Reports study found that electric vehicle owners save $6,000-$10,000 over the life of the vehicle compared to owning a comparable gas-powered vehicle. This is largely due to the reduced maintenance and repair costs associated with EVs.
Additionally, EVs have regenerative braking systems that turn friction into power, resulting in significantly reduced brake wear. The brake fluid in EVs also tends to stay cleaner, further reducing maintenance needs. However, it is important to note that EVs are not completely maintenance-free. The largest potential maintenance expense for an EV is the battery pack. While these batteries are designed for extended life, they will eventually wear out and need to be replaced.
To maintain an EV, it is recommended to follow the manufacturer's suggested maintenance schedule. This includes regular tire rotations and maintaining the appropriate tire pressure, wheel alignment, and balance. It is also important to keep an eye on the brake and windshield wiper fluid levels and to have the coolant system checked regularly. While EVs may require less maintenance overall, proper care is still essential to ensure the longevity of the vehicle.

Electric vehicles have fewer moving parts
Electric vehicles (EVs) have fewer moving parts than internal combustion engine vehicles, which makes them more cost-efficient and easier to maintain. With only a handful of moving parts in the electric motor, there is less wear and tear, and therefore less need for maintenance and repairs. This means that maintenance and repair costs for EVs are significantly lower than for gasoline, diesel, and internal combustion engine vehicles. For example, data from Tusker, a UK fleet vehicle operator, showed that over 90,000 miles or 10 years, the total servicing cost for an electric car was £917.70 ($1,157), compared to £1,935.34 ($2,441) for an internal combustion engine car—a difference of almost $1,300.
The lack of an internal combustion engine means there is no oil to change, no gaskets to replace, and no valves to clog up. EVs also do not require traditional automatic transmissions, although they may have a gear reduction 'transmission' or gearbox containing lubricant. The high-voltage power electronics and electric motors are typically cooled by a separate cooling system, and the high-voltage battery pack is also cooled. While EVs do not require engine oil, they do use oil in their transmissions and coolant to chill the battery pack. These fluids are consumed more slowly than in internal combustion engine cars, but their levels still need to be checked and potentially topped up.
EVs also undergo rigorous safety testing to meet the same standards as modern-day vehicles. Standards have been set for limiting spillage in the event of a crash, and measures have been taken to isolate the high-voltage system's chassis. The manufacturer has designed the system to deactivate the high-voltage electric system in the event of an accident.
Despite requiring less maintenance overall, EVs still require regular scheduled maintenance to ensure their longevity. This includes rotating the tires every six months to prevent uneven wear and tear, inspecting the brakes and brake fluid after 22,000 miles or two years, and checking the coolant system every 150,000 miles or five years. Additionally, the battery pack should be inspected every six months for leaks and performance.

Electric vehicles have a different impact on the environment
Electric vehicles (EVs) have a different impact on the environment compared to traditional internal combustion engine (ICE) vehicles. While EVs produce zero tailpipe emissions, there are still emissions associated with the production and charging of these vehicles. The impact of EVs on the environment depends on various factors, including the energy sources used for electricity generation and the carbon intensity of battery manufacturing.
EVs typically produce lower tailpipe emissions than conventional vehicles, and zero tailpipe emissions when running solely on electricity. This is because EVs do not have internal combustion engines that burn gasoline or diesel, which are major sources of direct emissions. However, it is important to consider the upstream emissions associated with electricity production and the battery manufacturing process.
The production and charging of EVs can result in carbon pollution, depending on the energy sources used for electricity generation. For example, power plants that use coal or natural gas emit carbon pollution, while renewable sources like wind or solar energy do not. The carbon intensity of electricity generation varies across different geographic regions, affecting the overall emissions associated with EVs.
Additionally, the manufacturing process of EV batteries can contribute to carbon emissions. Some studies suggest that the additional energy required to produce EV batteries can lead to higher carbon pollution during the manufacturing phase compared to gasoline cars. However, over the lifetime of an EV, the total greenhouse gas emissions are typically lower due to the absence of tailpipe emissions and higher energy efficiency.
To minimise the environmental impact of EVs, it is important to consider the energy sources used for charging and the carbon footprint of battery production. By transitioning to renewable energy sources and improving battery manufacturing processes, the environmental benefits of EVs can be further enhanced. Overall, while EVs have a different impact on the environment, they offer a lower-emissions alternative to traditional ICE vehicles, particularly in regions with low-carbon electricity generation.

Electric vehicles require specialised tires
Electric vehicles (EVs) require less maintenance than standard cars, and they are also cheaper to maintain. However, there are some differences in how they are maintained, including the tires.
Weight
The weight of an EV is a crucial difference between vehicles with electric motors and combustion engines. The batteries installed in electric cars are much heavier than a full fuel tank, so the tires must be designed to bear higher loads. For example, XL tires have been specially developed for use with heavy loads.
Torque
The on-demand torque in an EV requires better traction because the tires grab the road surface and cause a lot of friction during initial acceleration. EV-specific tires are optimized to maximize grip and reduce wear.
Rolling resistance
The powertrain in an electric vehicle is more efficient than a traditional engine. It's just an electric motor spinning a wheel, so the rolling resistance becomes even more important in these cars. That resistance accounts for about 16% of the total energy used. Lower rolling resistance means increased electric range and higher efficiency, while also contributing to your car’s overall sustainability.
Noise
EVs are known for being very quiet vehicles, and EV-specific tires are designed to minimize road noise. Using a standard tire on an EV might result in a louder in-cabin experience than if you used the same tire on a gas-powered car, where tire noise would be masked by engine and wind noise.

Electric vehicles require regular checks and services to keep the warranty valid
Electric vehicles (EVs) generally require less maintenance than hybrid or standard cars, but regular checks and services are still important to keep the warranty valid and ensure the vehicle's longevity. While EVs have fewer moving parts and require fewer oil changes, there are several maintenance items to keep in mind.
Firstly, the high-voltage battery pack is a critical component that requires regular attention. While it is true that the battery pack does not need to be charged to 100% unless driving for extended periods, the coolant system used to manage the battery's temperature should be checked and changed approximately every 150,000 miles or five years. It is important to follow the manufacturer's recommendations for coolant changes, as some EVs, like the Tesla Model Y, advise against owners topping up the coolant themselves.
Secondly, EVs use regenerative braking, where the electric motor recharges the battery during braking, resulting in less frequent use of traditional friction brakes. Nonetheless, the brakes and brake fluid should be inspected and changed after approximately 22,000 miles or two years. It is important to use clean brake fluid to ensure the longevity of the braking system.
Additionally, tire rotations and maintaining the appropriate tire pressure, wheel alignment, and balance are crucial to sustaining performance and extending tire life. Tires should be rotated every six months to prevent uneven wear and tear.
While it is not legally required to service your EV at a dealership to maintain the warranty, it is essential to follow the manufacturer's recommended maintenance schedule and keep detailed records of all services and repairs. This includes saving receipts for any maintenance or repairs performed outside of the dealership, such as oil changes, tire rotations, or fluid flushes. Proper maintenance of your EV will not only keep the warranty valid but also ensure the vehicle's safety, lower insurance costs, retain its value, and meet any contractual obligations.
