100,000 mile warranty? Sounds like a reasonable deal for most cars, but for Tesla, it’s chump change.

According to a recent report from CNET, Tesla Motors has decided to extend the warranty on its flagship Model S sedan and make it one of the best in the entire automotive industry. Now, many Model S owners will get eight-year, unlimited-mile warranties, meaning that they can drive their cars all they want and still be under coverage from Tesla in case something breaks down.

Previously, the standard version of the Model S, which includes an 85kWh battery, was covered under a warranty that lasted for four years and 50,000 miles driven. In addition to that, Tesla gave buyers the option of extending the warranty to twice the standard, with eight-year, 100,000-mile coverage. The price tag for such extended coverage? $4,000.

Now, however, Tesla is doing away with that whole pay-for-extra-coverage thing. The CNET article reports that, from here on out, Tesla will service Model S battery packs no matter how much mileage a car has racked up over the years. So long as the car was purchased less than eight years ago, it will be covered under Tesla’s new warranty standards. Best of all, the unlimited-mile coverage is free.

As far as Tesla CEO Elon Musk is concerned, the new warranty update is a no-brainer. In fact, Musk says that, “in hindsight,” Tesla should have been using this policy from day one.

“If we truly believe that electric motors are fundamentally more reliable than gasoline engines, with far fewer moving parts and no oily residue or combustion byproducts to gum up the works, then our warranty policy should reflect that,” Musk wrote on Tesla’s website.

Whether or not the same generous warranty coverage will extend to lower-end versions of the Model S, such as the 60kWh battery version, remains to be seen.
