75D

75D is a designation used by Tesla for a specific battery-pack and drivetrain configuration applied to the Model S and Model X. In Tesla’s naming conventions, the number generally relates to battery capacity while the letter indicates the drivetrain configuration, with D standing for dual-motor all-wheel drive. The 75D designation represents a middle-range option in the era when Tesla offered multiple battery variants.

The 75D designation denotes a dual-motor all-wheel-drive version powered by a roughly 75 kWh lithium-ion pack. It was positioned to offer a balance between range and performance relative to other options in Tesla’s lineup, sitting between smaller, lighter variants and higher-capacity configurations that followed. The exact characteristics—such as acceleration, energy efficiency, and overall range—varied with wheel size, vehicle options, and driving conditions.

Production and market presence: The 75D appeared in Tesla’s lineup during the mid- to late-2010s and was available on both the Model S and Model X. As Tesla expanded and renamed its battery options, the 75D designation was progressively phased out in favor of newer configurations and nomenclature.

Impact and context: The 75D provided customers with the dual-motor, all-wheel-drive experience associated with Tesla’s mid-range pack, offering the benefits of AWD and a mid-tier energy capacity within the broader lineup. The designation is part of Tesla’s broader strategy of offering multiple battery options to cater to different performance, efficiency, and price preferences.
