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!

Abbreviation
Explanation

Cruise control although in Tesla speak you will usually see TACC
CCS
Combined charging system and a form of DC charging. For more information on the various options, see our guide to charging a Tesla.

When at the end of a model name signifies the car has dual motors
DAS
Sometimes called just DA and the collective term for Driver Assistance systems
DC
Direct Current and the faster method of charging the car and as used by superchargers
EAP
Enhanced or Extended autopilot and an option Tesla introduced that sits between the basic autopilot and full self driving
eMMC
embedded Multi Media Card and the memory used in the MCU which is causes so many issues with the MCU1. There is much more on eMMC failure here.
EPA
US Environment Protection Agency and one of the bodies that dictate the way range is measured
EV
Electric vehicle
FOB
The electonic key fob for opening the car
FSD
Full Self Driving and the highest set of autopilot capabilities although still not genuine self driving at the moment and may never get beyond advanced driver asist with the current cars
FWD
In Tesla speak is Falcon Wing Doors. In wider use also means Front wheel drive
HEPA
A high grade air filter removing pollen bacteria etc
HPWC
High Power Wall charger
HVAC
Heating Ventilation and Air Conditioning
HW2
The first version of Teslas autopilot hardware between ~Oct16 and Jul17. The term HW1 is not used but is the Mobileye system
HW2.5
The second version of Tesla autopilot hardware between ~Jul17 and ~Apr19
HW3
The third version of Teslas autopilot hardware and also referred to as Full Self Driving computer from ~Apr19
ICE
Internal Compustion Engine and a term given to petrol and diesel cars
ICEd
When a parking or charging space is blocked by an internal combustion car(ICE)
IR
Infinion motor and a type of electric motor used on some cars
kW
Kilo(1000) Watts and a measure of instantaneous power and essentially equal to the voltage x current
kWh
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.
LDW
Lane Departure Warning
LR
Long Range and a model variant, When applied to the MS or MX is roughly equivalent to the the 100 model.
LR+
Long Range model variant that had a few changes to extend the range
M3
Model 3
MCU
Generic name for the Media Control Unit or the large central screen in the cars
MCU1
Media Control Unit version 1 and used in early MS and MX until ~Mar18. Has a reliability issue over time (see eMMC)
MCU2
Media Control Unit version 2 and used in later MS and MX from ~Mar18 and a variant in Model 3
MS
Model S
MX
Model X
MY
Model Y
NEDC
New European Driving Cycle and the European equivalent of the EPA range calculation
NHTSA
National Highway Traffic Safety Administration and are commonly quoted in relation to safety statistics
OTA
Over the air and the way software updates are usually delivered
P
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.
P-
Also written P3D- and a P3D without some of the performance features such as larger wheels
P2D
Pin to drive which is a security feature enabling you to add a pin code to your car
P3D
A shorthand way of writing a Model 3 Performance
PHEV
Plug in Hybrid Electric vehicle and a car with both battery and petrol motors
PM or PMSRM
Permanent Magnet and a style of motor design
REX
A BMW term for an EV with a petrol Range EXtender which can charge the battery while the car is in use. The size of the petrol tank meant it could more or less double its range albeit party fueled by petrol.
RWD
Rear wheel drive and when applied to a Tesla means it only has a single motors
SC
Service Centre
SR
Standard Range and a model variant. When applied to MS and MX is roughly equivalenet to the 75 model.
SR+
Standard Range plus and a model variant
SuC
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
A version 3 supercharger, the latest form of supercharger with a peak delivery of 250kw for cars capable of taking that much.
TACC
Traffic Aware Cruise Control and the system that controls the speed of the car on autopilot
TPMS
Tyre pressure Monitoring system, each wheel has a sensor that detects the tyre pressure and reports to the car what it is enabling notification of low pressure or a flat.
TSLA
Tesla stock/share symbol
UMC
Universal Mobile Connector in its generic form. This is the portable charger you can just plug into a domestic socket using a suitable interchangeable connector and charge your car. This is however the slowest way to charge the car.
UMC1
The first version of the UMC and in Europe it supported 3 phase charging
UMC2
The second generation of the UMC and in Europe it only supports single phase charging
VIN
Vehicle Identification Number and the unique car number which Tesla uses to identify the car
Wh/Km
The number of watt hours it takes to drive one kilometer and a measure of efficiency and typically ranges from 160 to 270
Wh/M
The number of watt hours it takes to drive one mile and a measure of efficiency and typically ranges from 240 to 400

The phrase we posted above roughly translates to:
If you've rapid Direct Current Supercharging your Battery electric vehicle using the CCS charge plug standard on your Tesla Model S and pulled an instantaneous 140 kilo watts of electricity while using your Media control unit version 2 (ie big screen in the car) to find out which Autopilot hardware you have installed....
