Tesla working on an ‘eternal’ electric drive unit that will last for 1,000,000 miles


Tesla engineers are bent on developing an electric motor that can virtually traverse the entire predicament of mechanical problems in cars. According to Elon Musk, the company experts have has altered its target endurance for the advanced drive units of the electric vehicles, thus pertaining to the crucial section that houses the electric motor (or motors). To that end, the previous goal of the Tesla engineers were to achieve an impressive 200,000 miles. But the revised aim for their improved electric motors relates to an astronomical figure of 1,000,000 miles – which for all intents-and-purposes might make their gasoline counterparts completely obsolete.

This is what Musk had to say about the ambitious revision (the statement being made in a conference call during the company’s third quarter financial results) –

We are very happy with the quality of the drive unit. We changed the goal of the drive unit endurance from being approximately 200,000 miles to being a million miles – just basically we want drive units that just never wear out. That’s our goal. I think we made really good progress in that direction. the drive unit that are going out now and for the last several months have been excellent.


This statement came in the wake of recent problems attributed to some drive units manufactured by Tesla. In fact, as a consumer-protecting solution to these predicaments, Tesla had already introduced their ‘Infinite Mile Warranty’ in 2014, with the warranty covering both the battery pack and drive unit for 8 years and infinite miles. Moreover, Musk had gone on to suggest that most of these previous technical (and software) issues were fixed as of now. He offered an example of the progress made by Tesla –

We transitioned to automatic grease injection into the spline of the large drive unit – we had variation in how much grease was put into the spline and if not enough grease was put into the spline, it would have premature wear.

In any case, if interested, you can take a gander at how Tesla’s electric drive units are crafted at the factory level –
