Mercedes-Benz LS1938

Descriptions: The Mercedes-Benz LS1938 was a significant heavy-duty truck model produced by Mercedes-Benz in Brazil. It was notable for being the first Brazilian Mercedes-Benz truck with a fully electronic engine, the OM 457 LA from the BR 450 series. Here’s a summary of key aspects of the Mercedes-Benz LS1938: 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. Technology: The electronic engine aimed to improve fuel efficiency and engine durability compared to its predecessor (OM 447 LA). It also featured a “Top Brake” engine brake system as standard. The electronic system could limit power and torque in case of severe malfunctions like overheating. Market Position: It was a strong competitor in the extra-heavy truck segment in Brazil, competing with models like the Scania T 124 360 and Volvo NH 12 380. In 1999, the LS 1938 was the best-selling tractor unit in Brazil. Production Period: It was launched in 1998 and discontinued in 2005. Special Editions: A limited “500 Years of Brazil” edition with special colors and commemorative stickers was released in 2000.
