The influencing factors for torque distribution are not only the driving speed, the lateral and longitudinal acceleration and the steering angle, but also the difference in rotational speed between the individual wheels, the gear selected and the accelerator position.The main advantages of electro-mechanical control over an electro-hydraulic system relate to more refined driving dynamics - primarily due to the significantly faster response and speed-independent actuation of the discs over the entire adjustment range. The characteristics of the all-wheel drive control are dependent on the driving mode and the AMG DYNAMICS setting. In "Basic" and "Advanced", the 4MATIC system is in "Comfort" mode. In "Pro" and "Master" (standard for S-Model, included in the optional AMG DYNAMIC PLUS package for the base model) the 4MATIC system switches to "Sport" mode - for even more agile handling and an even higher threshold for the critical limits. The new AMG suspension with specific spring elements and the new, frequency-selective shock absorbers provides the basis for high directional stability and highly dynamic cornering characteristics with low body roll. At the same time comfort has been improved compared to the preceding model. The longitudinal and transverse dynamics are perfectly coordinated. All suspension components have been thoroughly revised in order to achieve a higher maximum lateral acceleration together with easy vehicle control at the limits. A McPherson strut design is used at the front axle. Suspension is taken care of by one wishbone below the wheel centre, one spring strut and one tie rod respectively. The special axle geometry reduces torque steer - for high comfort and agile handling. The new wishbone in aluminium reduces the unsprung masses enabling a more sensitive response from the springs. The brake callipers at the front axle are radially bolted - a technology from motorsport for more stability. The front axle carrier is rigidly attached and thus additionally stiffens the front section. The 4-link rear suspension is likewise rigidly connected to the body via a rear axle carrier, and therefore very torsionally rigid. There are three transverse control arms and one trailing arm plus specific bearings per rear wheel. This design ensures maximum driving stability and agility. The optional AMG RIDE CONTROL adaptive damping system enables the driver to choose between three different suspension control modes. The spectrum ranges from comfort-focused to sporty. The system operates fully automatically, adapting the damping forces for each wheel according to the driving situation and road conditions. This happens within milliseconds and is infinitely variable, with a wide spread of damping characteristics. The result is that it ride comfort and agility are enhanced in equal measure. The high-performance braking system ensures fade-resistant deceleration and short braking distances. On the base model, the 4-piston monobloc fixed front callipers act on 350 x 34 millimetre brake discs, while at the rear axle, 1-piston floating callipers act on 330 x 22 millimetre brake discs. The discs are internally ventilated and perforated to better dissipate heat and prevent brake fading, even with extreme use. The grey-painted brake callipers have white AMG lettering. The S-Model and the base model with the optional AMG DYNAMIC PLUS package are decelerated by an even larger braking system equipped with 6-piston fixed callipers and 360 x 36 millimetre brake discs at the front. In this case the brake callipers are painted red and bear a black AMG logo. The speed-sensitive, electro-mechanical sports power steering supports a sporty driving style with its direct turn-in ability. It has a special rack with variable transmission ratio and two characteristic curves: depending on which drive program the driver has selected, it provides taut and sporty or more comfort-biased steering feedback. The rigid mounting in the integral carrier connects the steering even better with the body and thus increases steering precision. The six AMG DYNAMIC SELECT drive programmes "Slippery", "Comfort", "Sport", "Sport +", "Individual" and "RACE" (standard for S-Model, included in the optional AMG DYNAMIC PLUS package for the base model) allow a wide spread of vehicle characteristics, from comfortable to dynamic. Numerous relevant parameters are modified:
The spectrum ranges from extremely stable to highly dynamic. On the multimedia display, when a drive program is selected, the new AMG DYNAMICS symbol is displayed together with the corresponding additional information.
With its sporty appointments and the MBUX infotainment system, the high-quality interior creates a close, personal connection between man and machine. The driver and front passenger are seated in an active position on contoured sport seats with firm lateral support. The standard upholstery as a combination of black ARTICO man-made leather and DINAMICA microfibre is timeless, and creates typical AMG highlights with double topstitching in red. The colour scheme is echoed by the red designo seat belts and the dashboard support trim in black DINAMICA microfibre with a red border. The chromed air vents are likewise upgraded with a red ring. As an alternative an upholstery in ARTICO man-made leather in neva grey/black with mid-grey double topstitching and light-longitudinal-grain aluminium trim is available. Yellow highlights feature throughout the interior on the S-Model, emphasizing the motor racing character of the more powerful models. Also included in the standard equipment are the AMG Performance steering wheel in nappa leather/DINAMICA microfibre with contrasting yellow topstitching, a yellow 12 o'clock marking, AMG steering wheel buttons and AMG logo, plus ambience lighting. In all models, the centre console in high-gloss black with a touchpad as standard has a further control array with additional switches controlling the 3-stage ESP, the manual transmission mode, the optional adaptive damping system AMG RIDE CONTROL and the optional AMG Performance exhaust system. In combination with the optional leather package, it features a silver chrome console surround. The combination of sporty design and sophisticated details is also featured in the MBUX infotainment system with its innovative operating and display concept. MBUX creates an even closer connection between the vehicle, driver and passengers. Emotionally appealing presentations underline the clear control structure and feature brilliant maximum-resolution 3D graphics. Visually, the two displays under one shared glass cover blend into a Widescreen Cockpit and as a central element consequently emphasise the horizontal orientation of the interior design. The customer can choose between the three AMG display styles "Classic", "Sport" and "Supersport" for the instrument cluster. The "Supersport" mode is particularly striking with a central, round rev counter and additional information presented in the form of bars to the left and right of the rev counter: with a three-dimensional perspective, they reach far into the background to an artificial horizon. And needless to say, the trailblazing voice control activated with the words "Hey Mercedes" is also on-board. Thanks to artificial intelligence, MBUX recognises and understands nearly all sentences from the fields of infotainment and vehicle operation, even if they are expressed indirectly. A perfect symbiosis between the driver and vehicle is ensured by the multifunction sport steering wheel in nappa leather with flattened steering wheel rim and perforated grip area, and depending on the upholstery, red, yellow or black topstitching and a facing in silver chrome. The galvanised steering wheel gearshift paddles allow an even sportier driving style with manual gear shifting. As standard the S-Models are equipped with the AMG Performance steering wheel in nappa leather/DINAMICA microfibre (optional for basic model). The AMG steering wheel buttons (standard for S-Models, optional for the basic variants in conjunction with the Performance steering wheel) allow the AMG driving modes to be accessed directly, and other AMG functions to be conveniently operated directly at the steering wheel. << Prev Page 2 of 2 |
