Having dug through Tesla’s latest firmware, Green posted on X a series of features that are believed to be missing from the cheaper vehicle – codenamed internally “E41”. There’s no concrete evidence of changes to the drivetrain, only that the cheapest Model Y could be offered in both all-wheel-drive and rear-wheel-drive configurations, with the potential for less powerful motors to be used. Analysis: A step in the wrong direction(Image credit: Tesla UK)The recent updates to both the Tesla Model Y and Model 3 ushered in some monumental improvements to interior fit and finish, sound insulation and the quality of materials and components used. As a result, both of these vehicles now feel like more serious propositions, veering away from the cheap finish and questionable build quality of the early Model S and Model Y. While the Model Y isn’t the premium proposition that the Cybertruck wants to be, it remains a volume seller and one that comes with a certain level of customer expectation.
