Tesla After 600,000 Kilometers - EV Motors

Tesla After 600,000 Kilometers

While gasoline and diesel vehicles have proven to be long-lasting, the future of electric vehicles is still up in the air.

A California based company known as Tesloop got into the limelight a few years ago due to its Tesla Model S. This car dubbed eHawk had been driven more than 400,000 miles (643,000 km) by the shuttle service provider.

Throughout the three years, the company kept track of all expenses. The total operational costs were $60,000, which equates to $0.15 per mile or $0.093 per km.

These were impressive figures, especially considering that a Lincoln Town Car would have cost $28000 more.

Status Of Batteries?

Batteries are the most vulnerable part of EVs. That’s why Tesloop had to change the batteries of eHawk twice.

The first battery pack was replaced at 194,000 miles (312,212 km) and the second was replaced at 324,000 miles (521427 km).

After nearly 200k miles, the first battery pack only showed a 6% degradation. The second battery pack, on the other hand, showed significant signs of deterioration, having lost 22% of its health after 324k miles.

It was later discovered that such a significant decline in battery health was caused by faulty battery voltage assembly.

Factors Of Battery Health Degradation

The company’s practice of fast charging the batteries several times per day was a major factor in their rapid deterioration.

Tesla itself suggests not to fast charge the battery up 100%. Besides this, it also recommends that the battery should not be fast-charged every day.

Car’s Interior

Tesloop had done an excellent job of maintaining the eHawk’s interior. The seats appeared to be clean and in good condition. So good in fact that they don’t need any treatment for the next several years.


This is especially impressive given that Tesloop is a shuttle service provider, and thousands of customers must have used the vehicle during its three-year 400k mile (643k km) journey.

Another Example Of High Mileage

Tesloop’s Model S isn’t the only Tesla crossing the 400,000 miles (643,000 km) milestone.

Another owner that initially used his vehicle for Uber also claims that his Model S70D has been driven more than 424,000 miles (682,360 km).

This vehicle from 2015 has been driven more than 70,000 miles (112,650 km) annually on average.

However, in this case, the battery health didn’t see much degradation. So, it was changed at 250,000 miles (402,336 km) under warranty.

And to our surprise, the interior of even this Model S looks in perfect condition even after so much use. Here is a look at it.

Replaced Parts

After so many miles, some of the parts had to be changed. These included:

– Front motor, replaced at 380,000 miles (611,550km);

– Front Upper Control Arms;

– Rear Upper Links;

– Front Lower Fore Links;

– Media Control Unit.

However, it makes perfect sense because, as with conventional vehicles, parts must be replaced as the vehicle’s mileage increases.

GeoTab’s Unique Tool

GeoTab provides a one-of-a-kind tool that can assist EV owners in determining the battery degradation over time for any specific car.

We experimented for a 2015 Tesla Model S and here is what the results showed.

Key Takeaways from GeoTab’s research are as follows:

– Battery degradation varies depending upon the car’s model & type. Here is how the battery degradation of Tesla Model S and Nissan Leaf vary;



– The EV’s battery, if properly taken care of, can outlast the car’s life;

– Battery degradation is normally in the range of 2.3% annually;

– EV battery degradation is non-linear. Here is how it looks in real life:

Final Verdict

In terms of battery degradation, the eHawk appears to be an outlier. Even Tesloop has a Model X with a stock battery that has only exhibited 10% battery degradation after 300,000 miles (482,803 km).

And, as previously mentioned, the battery in the Model S70D worked flawlessly for the 250,000 miles.

Aside from that, the standard 8-year warranty provides EV owners with additional support if any item needs to be replaced.

This demonstrates that electric vehicles are durable enough to last for extended periods.
