Electric vehicle maker Tesla Motors has increased the price of its ‘Full Self-Driving Capability’ package when purchased by Tesla owners via an over-the-air software update after the delivery of their vehicles.

The ‘Full Self-Driving Capability’ package aims to eventually bring full self-driving capabilities to Tesla electric cars. Tesla has been pre-selling the package since 2016, in coincidence with the launch of its second-generation Autopilot hardware suite in all of the company’s electric vehicles.

For adding the ‘Full Self-Driving Capability’ package to their vehicles, Tesla buyers have to first get the ‘Enhanced Autopilot’ package, which is available for $5,000 when a vehicle is ordered, or for $6,000 when purchased through an over-the-air software update.

Tesla buyers who get the ‘Enhanced Autopilot’ package can further go for the ‘Full Self-Driving Capability’ package by paying $3,000 while ordering it with the vehicle, or by paying $4,000 for purchasing it later over-the-air.

However, with the recently-implemented increase in the price of the ‘Full Self-Driving Capability’ over-the-air update, its cost has now gone up by an additional $1,000. As such, according to a listing on the online design studio for the Model S and Model X, the cost of the ‘Full Self-Driving Capability’ over-the-air update has increased to $5,000 from the previous price of $4,000.
