Mercedes-Benz

====1994 to 2014====
For the 1994 model year, Mercedes-Benz revised the naming system. Models were divided into "classes" denoted by an arrangement of up to three letters (see "Current model range" above), followed by a three-digit (or two-digit for AMG models, with the number approximately equal to the displacement in litres multiplied by 10) number related to the engine displacement as before. Variants of the same model such as an estate version or a vehicle with a diesel engine are no longer given a separate letter. The SLR and SLS supercars do not carry a numerical designation.

Today, many numerical designations no longer reflect the engine's actual displacement, but more of the relative performance and marketing position. Despite its engine displacement in two litres, the powerplant in the A45 AMG produces 355 brake horsepower so the designation is higher as to indicate the greater performance. Another example is the E250 CGI having greater performance than the E200 CGI due to the different engine tuning even though both have 1.8-litre engines. From the marketing perspective, E200 seems more "upscale" than E180. Recent AMG models use the "63" designation (in honor of the 1960s 6.3-litre [[Mercedes-Benz M100 engine|M100]] engine) despite being equipped with either a 6.2-litre ([[Mercedes-Benz M156 engine|M156]]), a 5.5-litre ([[Mercedes-Benz M278 engine|M157]]) or even a 4.0-litre engine.

Some models carry further designations indicating special features:
* "[[4MATIC]]" indicates the vehicle is equipped with [[Four-wheel drive|all-wheel-drive]].
* "[[BlueTec|BlueTEC]]" indicates a diesel engine with [[selective catalytic reduction]] exhaust aftertreatment.
* "BlueEFFICIENCY" indicates special fuel economy features (direct injection, [[start-stop system]], aerodynamic modifications, etc.)
* "CGI" (Charged Gasoline Injection) indicates [[Direct fuel injection|direct gasoline injection]].
* "CDI" (Common-rail Direct Injection) indicates a [[Common rail|common-rail]] diesel engine.
* "Hybrid" indicates a petrol- or diesel-electric [[Hybrid vehicle|hybrid]].
* "NGT" indicates a natural gas-fueled engine.
* "Kompressor" indicates a [[supercharger|supercharged]] engine.
* "Turbo" indicates a [[turbocharger|turbocharged]] engine, only used on A-, B-, E- and GLK-Class models.
* "AMG Line" indicates the interior or engine, depending which car, has been fitted with the luxuries of their AMG sports cars.

Model designation badges can be removed at the request of the customer.
