Classic Vintage Mercedes-benz

As before, some models' numerical designations do not match the motor's actual displacement; in these cases the number shows the model's relative performance within the class. For example, the E250 CGI has greater performance than the E200 CGI because of different engine tuning, even though both have 1.8-litre motors. Recent AMG models use the "63" designation (in honor of the 1960s 6.3-litre M100 motor) despite being equipped with either a 6.2-litre (M156) or 5.5-litre (M157) motor.
Some models carry further designations indicating special features:
- "4Matic" means the vehicle is equipped with all-wheel-drive.
- "Bluetec" indicates a diesel motor with selective catalytic reduction exhaust aftertreatment.
