The U.S. EV specialist is putting its proverbial money where its mouth is when it comes to its Model S 90D.

Several of Tesla‘s Model S vehicles have been utilized by shuttle service Tesloop since 2015. This month, one of the cars passed 400,000 on the odometer. Nicknamed eHawk, the electric vehicle boasts the highest recorded mileage of any 90D.

Tesloop provided plenty of data documenting the vehicle’s maintenance schedule and documentation of all repairs. During its three-year run, the 90D only needed three major services, and relatively few updates and minor repairs. Maintenance cost added up to $19K—a modest sum considering the car’s class and mileage.

For those concerned with battery power, the model needed two battery replacements: one at 194,237 miles, and a second at 324,044. Both replacements were covered for free; the second replacement occurred when the vehicle was brought in for a separate repair, and was conducted as a preemptive repair. In both cases, the batteries had only lost a small amount of their capacity.

Considering the still-youthful age of the U.S.-based car company, and the desirability of tried-and-true when big ticket purchases are involved, the hard info is a feather in Tesla’s cap. It is also valuable as a token of reassurance for drivers who may be hesitant to make the leap to electric. And Tesloop wasn’t shy about sharing this surmise: it believes the eHawk will log another 600,000 miles before its 8-year warranty runs out.

All of which makes the eHawk the mascot of the company. This year, so far.
