Here’s a summary of key aspects of the Mercedes-Benz LS1938:

Key Features:

Engine: OM 457 LA, 6-cylinder in-line diesel, fully electronic.
Power: 380 hp at 2,000 rpm.
Torque: 189 kgfm (1853 Nm) between 1,100 and 1,500 rpm.
Transmission: Likely a manual ZF transmission with multiple speeds (specific details may vary).
Configuration: Primarily available as a 4×2 tractor unit (LS), designed for hauling semi-trailers. A 6×4 version (2638) was also available.
Brakes: Notably featured integral disc brakes on all four wheels (4×2 version), an innovative feature for its time in Brazilian trucks. ABS was offered as an option.
Cab: The cab was similar to previous models with some aesthetic updates and comfort features. Later, a high-roof version (“teto alto”) was introduced. In 1999, the LS 1938S version was launched, which was the first heavy truck from Mercedes-Benz with a tilting cab in Brazil.
