Power system:
Engine: Usually equipped with Mercedes-Benz OM471 in-line
6-cylinder diesel engine, displacement is generally about 12.8
liters. The engine is powerful and available in a variety of
horsepower versions, such as 420 HP, 450 HP, 480 HP, 510 HP and
even 580 HP, to meet different transportation needs. Through EGR,
SCR and DPF technologies, it can meet high emission standards and
has good environmental performance and fuel economy.
Transmission: Matched with advanced automatic transmission, such as
the third generation PowerShift automatic transmission, with high
transmission efficiency, fast shift speed, clear logic and other
advantages. Compared to manual transmission, automatic transmission
can ensure the continuity of engine power output, improve vehicle
performance, and help reduce fuel consumption.
Chassis and suspension:
Drive form: The 4x2 drive form means that the vehicle has two
steering wheels and a drive shaft, which is suitable for high-speed
driving in good road conditions, and is often used in highway
transportation scenarios such as express transportation and
dedicated logistics.
Suspension system: the front axle generally adopts leaf spring
suspension to ensure a better carrying capacity; The rear axle is
usually equipped with air bag suspension, which can automatically
adjust the height according to different load conditions, improving
the stability and comfort of the vehicle. When loading and
unloading goods, the air suspension can also adjust the height of
the chassis to facilitate loading and unloading operations.
Rear axle speed ratio: the common rear axle speed ratio is 2.643,
2.733, etc. This smaller speed ratio design can enable the vehicle
to maintain a lower engine speed at high speed, reduce fuel
consumption, and improve transportation efficiency.
Cab:
Space layout: High roof flat floor design, spacious interior space
for the driver to provide a comfortable driving environment. The
layout of the cab is reasonable, and the central control operation
area is close to the driver's side, which is convenient for the

seats, which can provide good support and shock absorbing effect
and reduce the driver's fatigue. Some models are also equipped with
ventilation, heating and other functions to further enhance the
comfort of the seat. The steering wheel is designed for multiple
functions and integrates a variety of control buttons to facilitate
the driver to operate the stereo, Bluetooth phone, cruise control
and other functions during driving. In addition, the cab is also
equipped with automatic air conditioning, electric sunroof, large
size sleeper and other comfort configuration, providing a good rest
environment for the driver.
Safety configuration: Equipped with a series of advanced safety
systems, such as lane departure warning system, anti-collision
warning system, active brake assist system, ASR drive anti-skid
system, EBD electronic brake force distribution system, electronic
body stability system, etc., for the driver's driving safety
provides a full range of protection.
Appearance design:
The front face shape has a high degree of recognition, usually
using an exaggerated air intake grille design, with the
three-pointed star logo of Mercedes-Benz, showing the unique charm
of the brand. The body lines are smooth, the appearance design pays
attention to aesthetics, but also considers the principle of
aerodynamics, can reduce wind resistance, improve fuel economy.
