Why E-class was name the model in mercedes-benz?Answer is here.

[Guest samuel sum]

The 'E-Class' name first appeared in the USA with the face-lifted W124 in 1994 (the w124 was introduced in the US in 1986 but continued with the older models naming convention until 1994, when all Mercedes Benz models switched to a new system i.e. E320 instead of 300E). The 300D continued to be the fuel economy option over the 4 and 6 cylinder gasoline engines, and the gasoline V8 engines (available after 1992) increased gasoline power outputs further. The V8 powered sedans/saloons were named 400E/500E from 1992-1993, and E420/E500 after 1993. Likewise, the 3-liter cars (e.g., '300E') where also re-badged to 'E320' with the new 3.2 litre engines and naming rationalization of 1994. For a short period Mercedes offered a limited production sport version of the W124, created with and assembled by Porsche. This was called the 500E. Saloon/Sedan, Coupé, Convertible and Estate body configurations were offered.
