In the automotive world, the terms JDM, EDM, and USDM are used to describe the market a vehicle was originally built for and the specifications it follows. These terms are not only about where a car brand comes from, but also about regulations, engine options, features, design, and driving characteristics.

JDM cars usually follow Japanese regulations and customer preferences, featuring:
- Right-hand drive (RHD) configuration

- Compact dimensions suited for Japanese roads
- Performance-focused versions for certain models
Examples of famous JDM cars:
- Nissan Skyline GT-R R34

EDM cars follow European standards, including:
- European emissions regulations
- Strict safety requirements
- Mostly left-hand drive (LHD) configuration
- A balance between performance, comfort, and high-speed stability
Examples of EDM cars:

Key Differences Between JDM, EDM, and USDM
| Category | JDM | EDM | USDM |
|---|---|---|---|
| Market | Japan | Europe | United States |
| Steering | Mostly right-hand drive | Mostly left-hand drive | Left-hand drive |
| Main Focus | Handling and technology | Performance and refinement | Power and size |
| Popular Engines | Turbocharged small engines, high-revving engines | Turbo engines, V6, V8, advanced powertrains | Large displacement V6 and V8 engines |
| Vehicle Size | Compact | Medium to large | Generally larger |
| Modification Culture | Very strong | OEM+ and performance tuning | Muscle and horsepower-focused |
- JDM represents Japanese-market vehicles known for lightweight design, advanced engineering, and legendary tuning culture.
- EDM represents European-market vehicles famous for precision handling, luxury, and engineering excellence.
- USDM represents American-market vehicles known for powerful engines, large dimensions, and aggressive performance.
However, these terms only describe the original target market of a vehicle. A Japanese car sold in America is not automatically JDM. For example, a Toyota Supra built for the Japanese market is JDM, while a Supra sold with U.S. specifications is considered USDM.
