MB 1620 v1.0 1.54

The Mercedes-Benz L 1620 is a true legend on Brazilian roads. It's a semi-heavy truck that earned its iconic status through its robustness, reliability, simple mechanics, and excellent cost-benefit ratio. Even though its production officially ended in 2011, it remains incredibly popular in the used truck market and is a common sight across Brazil.

Here's a breakdown of what makes the MB 1620 so well-known:

Key Features and Design:

Robust Construction: The 1620 was built to withstand the challenging conditions of Brazilian roads. Its chassis and components are known for their durability.

Simple Mechanics: A major selling point was its straightforward mechanical system. This made it easier to maintain and repair, even in remote locations, contributing to lower operating costs and a preference among independent truck drivers.

Versatility: The 1620 was widely used for various applications, including:

Carroceria aberta (flatbed/stake bed): For general cargo.

Baú (dry van): For protected cargo.

Caçamba (dump truck): For construction and agricultural materials.

Tanque (tanker): For liquids.

Guincho (tow truck): For vehicle recovery.

It was available in different axle configurations, most commonly as a truck (6x2) with a third axle, but also as a toco (4x2).

Driver's Cab: While not as luxurious as modern trucks, the 1620's cabin was practical and functional for its time, providing a good working environment for drivers.

Engine and Performance:

Mercedes-Benz OM 366 LA Engine: This was the heart of the 1620's success. It's a 6-cylinder in-line turbocooler diesel engine. Over its production run, there were variations in power output to meet evolving emissions standards (Proconve).

Earlier versions might have around 204 hp (as in the OM 366 A turbo, for example).

Later versions, especially the "Eletrônico" (Electronic) models, featured the OM 906 LA engine, offering around 211 hp and 71 kgfm of torque (in the Classic version) or 231 hp and 83 kgfm of torque (in the Eletrônico version).

The "bomba grande" (large pump) versions refer to the mechanical injection pump, highly valued for its simplicity and robustness.

Transmission: Typically equipped with manual transmissions, like the Mercedes-Benz G 85-6, which offered good gear ratios for various loads and terrains.

Fuel Economy: For its class and era, the 1620 was considered to have reasonable fuel consumption, which further contributed to its popularity.
