Tesla Model Y Teardown: Autopilot 3.0, Steering and Braking Systems

Automated driving-capable hardware; based on Munro teardown survey data



  The Model Y is basically designed following the design of the Model 3, with about 54% of the vehicle's parts being carry-over parts. The mechanical parts of the steering and braking systems are basically the same as those of the Model 3, but compared to the 2017 Model 3 that Munro previously surveyed, the driver assistance system has been enhanced to Autopilot 3.0 (from April 2019), which supports automated driving.

  This report describes the steering and brake system components based on the analysis report of the teardown survey of the 2020MY Tesla Model Y, AWD performance upgrade package (456 HP) 5-seater version conducted by Munro & Associates, Inc. (Munro). Parts not mentioned in this paper, as well as weight, manufacturing process analysis, and cost analysis for all parts, are shown in the main body of Munro's full report.
