Hot on the heels of the world premiere for the new Mercedes‑Benz E-Class, its first high-performance variant is on the way from Mercedes-AMG. The E 43 4MATIC with the 3.0-litre V6 biturbo engine on board will represent the most powerful variant of the executive saloon when it is introduced in September 2016. With two new turbochargers and corresponding software applications, the supercharged six-cylinder engine delivers an output of 295 kW (401 hp).
As ever, the standard-specification AMG Performance 4MATIC four-wheel drive combines optimum traction with high agility on the E 43, thanks to rear-biased torque distribution with a front-to-rear ratio of 31:69 percent. The 9G-TRONIC automatic transmission with shorter shift times, the retuned sports suspension based on the AIR BODY CONTROL air suspension and the more direct steering ratio also provide for signature AMG Driving Performance.
“The new E 43 4MATIC offers impressive driving dynamics coupled with cutting-edge efficiency. Twin turbocharging, features adopted from motorsport and the characteristic AMG design immediately indicate to our customers that the new E‑Class from AMG offers pure Driving Performance coupled with cutting-edge technology and intense emotion,” notes Tobias Moers, CEO of Mercedes-AMG GmbH.
On the E 43 4MATIC, Mercedes-AMG has upgraded the six-cylinder engine’s output by 25 kW (34 hp) to 295 kW (401 hp) with the aid of two larger turbochargers and sophisticated software applications. The ample peak torque of 520 Newton meters is available right from a low engine speed of 2500 rpm.
This package guarantees performance on a par with many a sports car: the new E 43 4MATIC reaches a speed of 100 km/h from a standing start in 4.6 seconds, while its top speed is electronically limited to 250 km/h.
Sporty and distinctive: the exterior design
The looks of the E 43 4MATIC also render it immediately recognisable as a member of the AMG family. Apart from underscoring the powerful and self-assured appearance, three large openings in the front apron also ensure an optimum flow of air to the coolers. Two elegant cross fins on the outer cooling openings enhance the vehicle’s visual presence. The diamond grille with chromed pins, a louvre in high-gloss black and the AMG lettering represent further hallmarks of the AMG 43 models.
The side view is dominated by high-sheen 19-inch AMG five-spoke light-alloy wheels painted in high-gloss black. The rear end also features characteristic highlights, with two chrome-plated quad-flow exhaust tailpipes conveying a particularly sporty aesthetic. The rear apron trim in diffusor look comes in silver chrome, while the standard-specification spoiler lip on the boot lid is painted in the body color.
Sporty look with model-specific details: the interior design
The interior reinforces the dynamic calibre of the new E 43 4MATIC with numerous individual details. The driver and front passenger find a secure position in the sports seats even when driving at speed, thanks to the improved lateral support. The upholstery in ARTICO man-made leather/DINAMICA microfibre in black (optionally: nappa leather) features a distinctive layout and red topstitching. To match the seat design, the door centre panels and the dashboard are finished in ARTICO man-made leather with red topstitching. Exclusive pedals, a black roof lining and red seat belts add further sporty highlights.
The multifunction sports steering wheel in black nappa leather with red contrasting topstitching and featuring a flattened bottom section is ideally suited to an emphatic driving style. The AMG instrument cluster delivers all relevant information in a clearly arranged layout optimised for a dynamic driving style. Two tube-style round dials, the 11.4 cm (4.5-inch) multifunction color display, the RACETIMER and the 280 km/h scale in chequered-flag design conjure up a sports car feel.
High on power, low on consumption: the AMG 3.0-litre V6 biturbo engine
The V6 biturbo engine boasts a high power output combined with low fuel consumption and emissions. The high power output of 295 kW (401 hp) is attributable, among other things, to new, larger turbochargers and the higher charge-air pressure of 1.1 bar. Installed close to the engine, the two turbochargers are especially spontaneous in their response.
The NANOSLIDE coating on the cylinder liners has also undergone further development in the Formula 1 V6 hybrid turbo engines from Mercedes-Benz. Especially tough and, therefore, wear-resistant, this coating also reduces friction, thereby contributing to higher efficiency. The same applies to the spray-guided multiple injection with up to 200 bar fuel pressure. The AMG power plant can be identified by the red aluminium insert in the engine cover.
Short shift times, high efficiency: the 9G-TRONIC
The 9G-TRONIC automatic transmission is specially matched to the requirements of the new E 43 4MATIC. The AMG developers have managed to reduce the shift times of the 9-speed transmission by means of a dedicated software application. The multiple downshift function enables more spontaneous short bursts of speed, while the double-declutching function in “Sport” and “Sport Plus” transmission modes makes for an even more emotional driving experience. Defined ignition intervention additionally enables faster gear shifting than in “Eco” and “Comfort” modes.
“Manual” mode can be selected using a separate button in the centre console. The gear changes are based on the selected transmission mode, and the driver can now change gear using the paddles on the steering wheel. Moreover, the transmission stays in the selected gear and does not automatically shift up when the engine speed reaches the limit.
More agility: the sports suspension based on AIR BODY CONTROL
For added agility, more neutral cornering behaviour and higher traction even when driving at speed, the developers in Affalterbach have designed a dedicated sports suspension on the basis of the AIR BODY CONTROL multi-chamber air suspension system. The Adaptive Damping System also features in a model-specific configuration and offers a choice of three modes – “Comfort”, “Sport” and “Sport Plus”. This provides for broader scope between a high level of comfort for longer journeys and sporty driving dynamics.
The four-link front axle is fitted with special steering knuckles and load-bearing joints; all components have been optimised in terms of rigidity. A more negative camber on the front axle and on the multi-link rear axle enhances lateral dynamics. The elastokinematics of both axles have been designed to be more rigid in general. All these measures improve agility, and boost the dynamics.
Rear-biased and agile: AMG Performance 4MATIC
The standard-specification AMG Performance 4MATIC four-wheel drive features rear-biased torque distribution with a front/rear axle split of 31 to 69 percent. This configuration provides for enhanced driving dynamics and higher lateral acceleration on the road as well as improved traction when accelerating.
In combining the permanent four-wheel drive with the 9G-TRONIC automatic transmission, the developers have opted for a change of concept: the single-stage transfer case of the four-wheel drive is flange-mounted on the 9G‑TRONIC as a separate system. On earlier generations of vehicles, the transfer case was integrated into the 7G-TRONIC PLUS. The new add-on solution makes it easier to modify torque distribution according to the model, thus enabling even more individual characteristics for the respective model series.
The new system is also more efffective than the earlier concept, by virtue of improved efficiency, reduced friction and a lower weight. Its compact design additionally means that it does not entail any space restrictions for passengers or luggage.
Characteristics at the tap of a finger: AMG DYNAMIC SELECT
With the five DYNAMIC SELECT transmission modes “Eco”, “Comfort”, “Sport”, “Sport Plus” and “Individual”, the driver can tailor the characteristics of the E 43 4MATIC Coupé to individual preferences at the tap of a finger. The available range extends from efficient and comfortable to extremely sporty. This modifies key parameters, such as the response of the engine, transmission, suspension and steering. Independently of the DYNAMIC SELECT transmission modes, the driver has the option of pressing the “M” button to switch directly to manual mode, in which gearshifts are executed exclusively using the shift paddles on the steering wheel. The suspension set-ups can also be selected as necessary.
The DYNAMIC SELECT “Sport” and “Sport Plus” transmission modes are configured with a clear emphasis on driving dynamics on the new E 43 4MATIC. This results from an agile accelerator pedal characteristic with direct set-up and emotional gear shifting with reduced shift times, double declutching and deactivation of certain cylinders. The increased idling speed additionally enables the vehicle to move off quickly and provides for faster acceleration from a standing start.
In order to increase efficiency, in “Eco” mode the ECO start/stop function and the gliding function reduce fuel consumption: when the driver releases the accelerator in a speed range between 60 and 160 km/h, the clutch is disengaged and the engine is decoupled from the powertrain.
The electronics reduce the engine speed to idling level, and the driving resistance is reduced by the compression and frictional forces of the engine in overrun mode.
Direct and with clear feedback: speed-sensitive sports steering
The speed-sensitive sports steering features a variable ratio on the E 43 4MATIC. It stands out with its precise, highly authentic feedback. Steering power assistance is available in a choice of two modes – “Comfort” or “Sport”. The relevant characteristics are automatically activated depending on the selected DYNAMIC SELECT transmission mode or can be personalised in Individual mode. Manual torque is increased in “Sport” mode, providing more feedback on driving conditions.
The large braking system with internally ventilated compound brake discs ensures reliable and quick deceleration of the saloon. Perforated discs in size 360 x 36 mm with 4-piston fixed calipers and AMG lettering are fitted on the front axle, while discs in size 360 x 26 mm with 1-piston fixed calipers feature at the rear.
Optional features with a sporty emphasis
The optionally available features also emphasize the sporty character of the E 43 4MATIC. These range from AMG seats with increased lateral support through nappa leather upholstery to 20-inch dichromatic wheels.
The new Mercedes-AMG E 43 4MATIC will have its world premiere at the New York International Auto Show in March 2016. The sales release date will be 20 June and the market launch will begin in September 2016.
