Automakers have long used the principle of unification of components and assemblies in order not only to offer customers a wider range of configurations, but also to reduce their own costs. Leaks from the Tesla documentation indicate that Model Y and Model 3 electric vehicles are capable of air suspension.
As Electrek explains, adaptive air suspension was initially available as an option for the Tesla Model S and Model X, but then became part of the standard equipment. It can be obtained by customers of the Cybertruck electric pickup truck, but Tesla is not in a hurry to offer Tesla air suspension to the younger electric cars of the brand. Moreover, last year Elon Musk denied rumors of intentions to release the Tesla Model 3 with adaptive air suspension, although at the stage of preparing the electric car for mass production, he did not exclude this possibility, and in 2018 the company even tested the prototype Tesla Model 3 with air suspension on the race track.
Last month, a similar option was even seen in the updated spare parts catalog for the Tesla Model 3 and Model Y, but Musk once again stated that electric cars should not be equipped with air suspension. On the pages of Reddit, according to the source, a Tesla employee published an excerpt from the technical documentation for the Model Y crossover, which implies that it can be equipped with an air suspension. At least the profile controller and wiring allow such an option to be implemented.
In the early stages of the Model 3 and Model Y life cycles, which are characterized by significant demand for these electric vehicles, Tesla tries to limit the range of modifications to the maximum to maintain high rates of machine production. The decision to abandon the use of air suspension is not dictated by technical limitations, but organizational. It is quite possible that as the production volumes of junior electric cars in the line increase, buyers will be given the right to pay extra for an adaptive air suspension.
