One of the key features of smart cars is their electric battery, which powers the engine and provides a smooth, quiet ride. But how long do smart Fortwo batteries last? On average, a smart car battery will last for between 4 and 5 years with regular use. However, this can vary depending on a number of factors, such as how often the car is driven and how it is maintained. With proper care, it is not unusual for a smart car battery to last for 6 years or more. Ultimately, how long a smart car battery lasts will depend on the individual user’s driving habits and maintenance routine.


Smart car engines are designed to last for approximately 150,000 miles. However, this will vary depending on how the car is driven and maintained. If the car is regularly driven in stop-and-go traffic or used for long trips on the highway, it will likely need to be replaced sooner. Additionally, regular oil changes and other routine maintenance can help to extend the life of the engine. Ultimately, the best way to determine how long a Smart Fortwo engine will last is to consult with a qualified mechanic.


For most vehicles, brakes should be replaced every 30,000 to 50,000 miles. However, the brake pads on a smart Fortwo may last up to twice as long as those on a standard car. This is due to the fact that smart Fortwos weigh significantly less than other cars, which puts less stress on the brakes. In addition, the unique braking system of a smart Fortwo helps to distribute the force of braking more evenly, resulting in less wear and tear on the pads. As a result, drivers of smart Fortwos can typically expect their brakes to last for 60,000 to 100,000 miles.


The lifespan of a smart Fortwo’s tires will depend on a number of factors, including the type of tires, how well they’re maintained, and the driving conditions. In general, however, you can expect your smart Fortwo’s tires to last between 30,000 and 50,000 miles. Of course, if you take good care of your tires and avoid driving in harsh conditions, you may be able to get even more mileage out of them. To extend the life of your smart Fortwo’s tires, be sure to check the pressure regularly and have them rotated according to the manufacturer’s recommendations.

The higher the mileage of the vehicle, the more repairs will need to be done.

A Smart car is expensive to repair for two reasons.

The first is that the Smart car is not as widely produced as other vehicles, making parts more difficult to find and in turn more expensive to purchase.

The second is that a Smart car has a complex electrical system that increases the length of time it takes to complete basic repairs.

How Long Before Smart Cars Start To Rust?

Tips To Prolong The Life Of Your Smart Car

Smart cars are owned by Daimler AG, the same company that owns Mercedes-Benz.

Having regular maintenance done by a Daimler or Mercedes dealership will ensure the technician is knowledgeable about your specific vehicle.

Check your Smart car’s warranty as it may have stipulations as to where maintenance can be performed.

The top recommendation to prolong the life of your Smart car would be to keep up on all recalls.

Replacing common recalls will prevent those same parts from going bad in your vehicle and causing larger issues.

Other parts of the Smart car should be regularly replaced to ensure optimal performance and health.

Some items that should be replaced are:

  • Vehicle fluids
  • Brakes and rotors
  • Windshield wipers
  • Spark plugs
  • Tires

Smart cars can be very loyal cars with a great price tag if you are also willing to invest in the needed repairs.
