Mercedes E 4MATIC enjoy the magic of a winter landscape

Posted December 15, 2009 | Category: Cars

Snow, hail, and icy surface temperatures are below freezing weather phenomena that characterize some of the roads during the winter season. E-Class 4MATIC features the perfect union between high traction, excellent stability, security at the top of the segment and exceptional levels of comfort. Mercedes-Benz E-Class 4MATIC, in sedan and station wagon, confirming its exceptional quality even on the demanding Timmelsjoch a mountain road at high altitude in Austria.

The four wheel drive system 4MATIC Mercedes-Benz is extremely important during the winter season, further enhances active safety of the car even on dry and wet road. The 4MATIC system features a 45:55 torque distribution between front and rear axle and a multi-disc limited-slip center differential with a basic locking torque of 50 Nm With this basic concept you get high levels of traction, as accelerating the shift to dynamic load the rear axle is offset by the increased torque of the rear wheels. The multi-disc differential lock is able to shift torque between front and rear axles, varying the split between 30:70 and 70:30 depending on the needs of the driver and the road surface conditions. The intervention of electronic control systems ESP ®, ASR and 4ETS is thus substantially limited, and the torque is always available to the driver, even in low grip road surface. The interventions of control systems is imperceptible.

In such situations a warning symbol flashes in instrumentation Yellow invited to adapt your driving style to the road.

4MATIC permanent four-wheel drive offers several advantages over systems that are activated only under conditions of low grip.

E-Class 4MATIC is designed for maximum traction in winter. To this end, the automatic detection of road conditions can adjust the operations of the electronic control system 4ETS traction for maximum acceleration can be compared to a minimum slip of the wheels, thereby ensuring excellent directional stability. This strategy also allows the car to move forward without hesitation even in frozen sections sloping bottom (μ-split) or both front wheels or rear without adhesion (μ-jump).

In snow and ice on roads full of twists and turns, the vehicle stability is mainly controlled dall'ASR, the anti-skid control, which will adjust the engine torque. The control of ASR thresholds vary depending on the conditions of your vehicle, measured continuously by the sensor system ESP. To maintain vehicle stability is necessary to control the longitudinal force curve by adjusting the torque of the motor, so they are always present sufficient lateral forces. During the journey cornering on roads with low friction, the torque of the motor is continuously adapted to the lateral limits of the tires.

Mercedes-Benz E-Class 4MATIC is equipped with one of the best in the world wheel drive. The idea behind the project, with the engine mounted longitudinally and the group transfer box and drive system creates a compact, lightweight system that minimizes friction losses and has many advantages over other systems for cars with transverse engine and wheel drive disengaged. Fuel consumption, for example, is more than just 0.2 to 0.6 liters per one hundred kilometers compared to an equivalent model with rear-wheel drive, while the noise fully meets the high standards of Mercedes-Benz.

The high driving comfort of Mercedes-Benz E-Class, thanks in part to DIRECT CONTROL obtained with adaptive dampers for optimum control of the stiffness of the suspension, and seats equipped with advanced features such as massage, and air conditioning. DIRECT CONTROL The system is optimized in weight and composed of three-arm front suspension and multilink independent rear suspension, implementing a selective adjustment of the suspension, automatically adjusting the damping to different driving situations and significantly increasing the driving comfort. The air suspension system, optional for all models and standard on 4MATIC E 500 4MATIC is combined with an electronic damping system that continues to change, developing a number of signals from sensors, controls each wheel separately. In this way, the wheel of the Mercedes-Benz E-Class as well as enjoy an outstanding ride comfort can rely on active safety and agility of top level sport.

During winter it is essential that the air-conditioned cabin is so perfectly balanced. Mercedes-Benz E-Class offers a sophisticated automatic climate control (THERMOTRONIC). In addition to regulate temperature separately for driver, front passenger and rear passengers, this system also allows you to make custom presets. It also features a sensor for detecting the presence of harmful substances which automatically switches to recirculation mode if it detects a sudden increase of the percentage of carbon monoxide and nitrogen oxides in outdoor air, such as in tunnels. Another strong point of the system is THERMOTRONIC heating function remaining: pressing the "Rest" switched off the engine when the cab is heated and ventilated for 30 minutes. E-Class is equipped as standard with dual-zone automatic air conditioning (THERMATIC), which purifies the air through the car a great combination filter sealed with an efficiency equal to 96-98% thanks to the active carbon layer is able to filter even the smallest particles of harmful gases.
