Technical Description of the Original Model | Euro Truck Simulator 2

The Mercedes-Benz LS 1634 is a 4x2 highway tractor developed for heavy-duty long-haul transportation and semi-trailer operations. It stands out for its structural robustness, high low-RPM torque, and ability to operate on domestic and international highways.

MECHANICAL SPECIFICATIONS

Diesel engine options, depending on model year and configuration:

Mercedes-Benz OM 447 LA: Inline 6-cylinder engine, 11,967 cm³, turbocharger, and charge-air cooler (intercooler). In one configuration, it produces 360 hp at 1,900 rpm and 1,650 Nm of maximum torque at 1,100 rpm.

Mercedes-Benz OM 457 LA Euro III: Inline 6-cylinder engine, 11,967 cm³, turbocharger, intercooler, and electronically controlled fuel injection. It delivers 340 hp at 1,900 rpm and 1,450 Nm of torque at 1,100 rpm.

Both engines are designed to provide strong pulling power, low-RPM responsiveness, and reliable performance in heavy-duty transport operations.

TRANSMISSION AND DRIVETRAIN

• Gearbox: ZF 16S-1650, manual, with 16 synchronized gears (8 main ratios with a range splitter).

• Clutch: MFZ 430, 430 mm single-plate dry clutch with servo-assisted operation.

• Drivetrain configuration: 4x2, with a rear drive axle.

• Front axle: Mercedes-Benz VL 3/7 D-5.

• Rear axle: Mercedes-Benz HL 7/022 D-12.3.

• Differential: Equipped with a differential lock to improve traction on low-grip surfaces.

• Differential ratios: Vary depending on configuration, with documented ratios including 3.43:1 and 3.71:1.

CHASSIS AND SUSPENSION

The truck features a ladder-frame chassis designed to withstand pulling forces and the loads transferred by the semi-trailer. The tractor configuration includes a 2-inch fifth wheel.

The suspension system uses semi-elliptic leaf springs, double-acting telescopic shock absorbers, and stabilizer bars. This setup is engineered to provide structural strength, directional stability, and durability during heavy-duty transportation.

BRAKING SYSTEM

• Drum service brakes on both axles.

• Dual-circuit pneumatic braking system.

• Auxiliary engine brake.

• Top Brake system, designed to increase auxiliary braking performance and reduce continuous use of the service brakes.

• Spring-actuated parking brake with pneumatic release.

• Load-sensitive brake regulation system (ALB), depending on equipment specification.

ELECTRICAL SYSTEM

• Nominal voltage: 24 V.

• Alternator: 28 V / 80 A.

• Batteries: 2 × 12 V, 135 Ah each, according to the documented configuration.

WEIGHTS, CAPACITIES AND WHEELS

• Gross Vehicle Weight (GVW): Up to 17,300 kg in the documented configuration.

• Gross Combination Weight (GCW): Up to 45,000 kg in the specified highway configuration.

• Fuel tanks: Documented configuration of 2 × 300 liters, depending on version.

• Tires: 295/80 R22.5.

• Wheels: 8.25 × 22.5.

ACCESSORIES AND EQUIPMENT

Depending on the model year, version, and factory configuration, the truck may feature a sleeper cab, power steering, optional power take-off (PTO), fifth-wheel coupling for semi-trailers, differential lock, Top Brake auxiliary braking system, and various fuel tank, lighting, and interior equipment configurations.
