Driving Performance – the AMG brand promise and the typical character traits can now be experienced by an even broader target group. The new C 43 AMG 4MATIC expands the product range of the performance and sports car brand of Mercedes-Benz with another new AMG sports model. As an attractive entry into the world of AMG, the C 43 AMG 4MATIC combines a 270-kW (367-hp) 3.0-litre twin-turbo V6 engine with a permanent Performance all-wheel-drive system and sophisticated suspension technology adopted from the Mercedes-AMG C 63. The result is fascinating Driving Performance and the hallmark emotional expressiveness of the brand. The new AMG sports model is available as a saloon and an estate model, and makes the extensive product line-up within the C-Class range even more attractive.
The new AMG sports models are distinguished by convincing product substance. Even at first glance, the characteristic AMG body styling leaves no doubt that this model is part of the Mercedes-AMG model family. Another indication for the new model strategy is found in the form of a special AMG badge on the front wings. From an engineering standpoint the AMG sports models perfectly deliver on the visual promise of a sporty character with a powerful engine, the standard-fit all-wheel drive system with rear-biased torque split, and sophisticated suspension solutions.
Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH explains: “With the C 43 AMG we present the second sporty and emotionally expressive vehicle in our product line. It combines the power of a strong twin-turbo V6 engine with a high level of emotional expressiveness, and avails itself of the technical DNA of the new C 63. The new sports models represent a convincing proposition for our customers: sports car technology and motor racing fascination become more attainable and in the process appeal to a broader customer base.”
Authentic driving dynamics thanks to hallmark AMG DNA
The new C 43 AMG 4MATIC is based on the most powerful production model of the C-Class, the C 400 4MATIC. The engineers have revised many technical features of the new AMG sports model. Their objective: a high level of authentic driving dynamics geared towards the Mercedes-AMG C 63. To this end, a host of suspension components were adopted from the top-of-the-line V8 model. The driver also feels the DNA of the C 63 in the application of the engine and transmission management. Agility and sportiness dominate the intense driving experience in the C 43 AMG 4MATIC on every kilometre.
The new 3.0-litre twin-turbo V6 engine is part of the BlueDIRECT engine family from Mercedes-Benz. Technical advances including a modified boost pressure allowed the AMG engineers to increase the engine’s power output and torque. With 270 kW (367 hp) and 520 Nm (384 lb-ft) the V6 engine sets new standards in its segment – which is evident in the convincing performance: a sprint time from zero to 100 km/h (62 mph) of 4.9 seconds (Estate: 5.0 seconds) underscores the sporty temperament of the C 43 AMG 4MATIC. With a combined fuel consumption of 7.6 litres per 100 kilometres and CO2 emissions of 178 grams per kilometre (Estate: 7.7 litres and 180 g CO2 per km) the new top-of-the-line V6 model defines an absolute top position in the competitive environment.
Thanks to a hefty torque curve the new AMG sports model is agile, direct and dynamic. With the help of various AMG-specific drive programmes the driver is able to tailor the character of the C 43 AMG 4MATIC to his or her personal preferences: the modes “Eco,” “Comfort,” “Sport” and “Sport Plus” as well as “Individual” are available to choose from for this purpose. The drive programmes adjust the suspension, steering and powertrain as desired, and are selected conveniently with the AMG DYNAMIC SELECT switch to the left of the touchpad.
Especially the “Sport Plus” programme delivers impressive hallmark AMG dynamics and enhances the emotional appeal: partial cylinder suppression during gear changes by means of a momentary and precisely defined retardation of ignition and injection under full throttle speeds up the gear changes, and can also be acoustically experienced by the driver. The emotional double-declutching functions during downshifts and the “exhaust rumbling” in overrun mode provide the fitting accompaniment. The throaty engine sound – a hallmark AMG experience – also plays a crucial role in the most powerful V6 model: to this end, the engineers have developed a new sports exhaust system with lower back-pressure and reduced weight.
The driving sensation is also characterised by the set-up of the accelerator pedal: the more the driver changes the AMG DYNAMIC SELECT settings from “Eco” towards “Sport Plus,” the more spontaneous and dynamic is the throttle response of the twin-turbo V6 engine. The driver also experiences authentic and emotional dynamics during engine start if desired: when the twin-turbo V6 engine is started in the “Sport Plus” drive programme, the engine speed quickly jumps to 2000 rpm for a moment before immediately settling back down to idle speed. Whether the driver wants to experience the engine start accompanied by a sporty or a more subdued sound depends on the most recently activated drive programme – it remains stored for four hours.
The “Eco” programme integrates an ECO start/stop function and a sailing function to reduce fuel consumption: when the driver releases the accelerator in a speed range between 60 and 160 km/h (37 and 100 mph), the clutch of the transmission is disengaged and the engine is decoupled from the powertrain. The electronics reduce the engine speed to idle level, and the driving resistance is reduced by the compression and frictional forces of the engine in overrun mode.
7G-TRONIC PLUS automatic transmission with short response times
The 7G-TRONIC PLUS automatic transmission responds with superior composure or maximum spontaneity depending on the driver’s preference and selected drive programme. The “Sport Plus” mode delivers thrillingly short response times: the driver’s shift commands are implemented at lightning speed – the drivetrain responds spontaneously and precisely. The development engineers also take advantage of numerous hardware and software solutions of the C 63 in this regard. The ‘M’ button on the centre console allows savouring the high pulling power across the entire rev range. In manual transmission mode the 7G-TRONIC PLUS no longer shifts to the next higher gear on its own, not even when prompted by kick-down or upon reaching the redline speed. The driver alone makes the decisions about his or her shift request via the steering-wheel paddle shifters.
The momentary ‘M’ mode offers another feature: it combines the performance of manual gear changes with automatic upshifts and downshifts. The driver has the option to shift up or down at any time with the paddle shifters. If no gear change is requested, the transmission independently reverts to the automatic shift mode after a defined period of time has passed.
The 7G-TRONIC PLUS automatic transmission features a dual-turbine torsional damper with speed-sensitive centrifugal pendulum, which minimises vibrations and enhances the passengers’ perceived comfort.
