Tesla terms and abbreviations

You may be looking at buying a Tesla and are confused with many of the terms and abbreviations that are being thrown around on the internet. If you've SuC your BEV using CCS on your MS and pulled 140 kw while using your MCU2 to find out which AP HW and that all makes perfect sense then you probably don't need this list, but for others, it might just help!

Kilo(1000) Watts for an hour and a measure of stored or consumed energy
L or Ludy
Ludicrous and a feature on most performance models of the Model S and X. The cars are limited as much by the battery output as the motors and the ludicrous update effectively increased the max current the battery was allowed to deliver thereby increasing power.
L1 L2 L3
Different types of charging equipment and speed, roughly translate to L1 - portable/UMC charging, L2 - high power/dedicated charge point and L3 - DC charging.
Lane Departure Warning, a safety feature to notify the driver if the car has drifted out of lane.
Derived from the words Light and a technique for measuring the accurate relative position of objects using a laser light. It is a sensor used in many self driving systems but not adopted by Tesla.
Long Range and a model variant, When applied to the MS or MX is roughly equivalent to the the 100 model.
Long Range model variant that had a few changes to extend the range
Model 3
Generic name for the Media Control Unit or the large central screen in the cars
Media Control Unit version 1 and used in early MS and MX until ~Mar18. Has a reliability issue over time (see eMMC)
Media Control Unit version 2 and used in later MS and MX from ~Mar18 and a variant in Model 3
Machine Learning, a statistical technique to train a computer to perform a task by using thousands of examples.
Mid Range cars sitting between Standard Range and Long Range.
Model S
Model X
Model Y
New European Driving Cycle and the European equivalent of the EPA range calculation
National Highway Traffic Safety Administration and are commonly quoted in relation to safety statistics
Neural Network - a variation of Machine Learning and Artificial Intelligence that is used as part of Autopilot, Auto high beam and auto windscreen wipers
Navigate on Autopilot. A feature that is part of EAP and FSD.
Over the air and the way software updates are usually delivered
At the beginning of a model name an indication the car is a performance model
P xx D
Old style naming convention for the MS and MX. The leading P if present indicated a performance model, the xx indicated the approx battery size, and the trailing D if present indicated if it was dual motor (all wheel drive). Some early MS were P85+ where the + indicated a higher level of performance to a P85.
Also written P3D- and a P3D without some of the performance features such as larger wheels
Pin to drive which is a security feature enabling you to add a pin code to your car
A shorthand way of writing a Model 3 Performance

Permanent Magnet and a style of motor design
Can mean either Premium Upgrade pack or Performance upgrade pack depending on context.

Standard Range and a model variant. When applied to MS and MX is roughly equivalenet to the 75 model.
Standard Range plus and a model variant
Super Charging which is rapid DC charging at a Tesla supercharger location you see in various locations.
SuC v2
A version 2 supercharger, usually insalled in pairs and where cars share a peak output of approx 150kw.
SuC v3
