Mercedes-Benz A35 AMG
First Look: The New Mercedes-AMG A 35 4MATIC
Emotive, agile and digital: with the A 35 4MATIC, Mercedes-AMG is presenting a completely new entry-level model in the world of driving performance. It is based on the new Mercedes front-wheel drive platform and is powered by a new 2.0-liter four-cylinder turbo engine with output of 225 kW (306 hp). Body shell, suspension, all-wheel drive, transmission, driving programs, fine tuning – every detail has been designed for maximum driving dynamics without compromising on everyday comfort. The performance at sports car level (acceleration 0-62 mph in 4.7 seconds) and the specific design also strengthen the identity as a member of the performance family. A true AMG hot hatch.
The new A 35 4MATIC expands the AMG model portfolio as an attractive entry-level model in every respect. Because the development of the A 35 4MATIC was integrated into the development process of the new Mercedes-Benz
A-Class right from the start, it was developed at the same time as the future A 45 4MATIC, making it was possible to inject the AMG DNA into every detail.
Reinforced body-in-white with increased torsional stiffness
Specific measures to strengthen the front section of the bodyshell form the basis for the precise turn-in ability and the toe and camber stability of the chassis components, even when driving at speed. A so-called “shear panel”, a bolted aluminium plate under the engine, increases the torsional stiffness of the front section. Two additional diagonal braces at the front of the underbody also reduce torsion and increase the stiffness.
New four-cylinder turbo engine with output of 225 kW (306 hp)
The 2.0-liter turbo engine is a new development and is based on the M 260 four-cylinder engine in the new A-Class. The new drive boasts a spontaneous response to accelerator pedal commands, high tractive power (400 Nm max. torque from 3,000 rpm), a supremely lively response and an emotional engine sound. The crankcase made of high-strength, lightweight die-cast aluminium reduces the vehicle weight where it matters most for driving dynamics
Sophisticated turbocharging with twin-scroll turbocharger
A twin-scroll turbocharger is used for turbocharging. It combines optimum responsiveness at low engine speeds with a strong power increase at higher speeds. The housing of the twin-scroll turbocharger is divided into two parallel ducts. Together with two separate exhaust ducts in the exhaust manifold, this makes it possible to channel the exhaust gases separately on the turbine wheel.
The cylinders are divided into two cylinder groups and each is directed onto a turbine flow of the twin-scroll turbine. The cylinder groups are defined based on the ignition sequence.
This results in a further advantage of twin-scroll technology, i.e. minimization of the mutually adverse effects of the individual cylinders on the gas cycle. The exhaust gas back pressure is reduced and gas exchange and engine efficiency are improved.
Numerous engine measures increase efficiency
The high technological standards of the new four-cylinder engine are also underscored by numerous efficiency-enhancing measures. These include CAMTRONIC variable valve control, intelligent thermal management for engine and oil, high-precision piezo injectors and multi-spark ignition. In production, the patented CONICSHAPE cylinder honing reduces internal engine friction and also increases efficiency.
Agile gear ratios: AMG SPEEDSHIFT DCT 7G dual-clutch transmission
The AMG SPEEDSHIFT DCT 7G dual-clutch transmission also contributes to the agile and dynamic character of the new A 35 4MATIC. The gear ratios have been configured so that the driver experiences very spontaneous acceleration in all speed ranges, combined with fast shifting and optimum connections when shifting up.
The standard RACE-START function allows maximum acceleration from stationary and is a highly emotional experience. The functions of the AMG SPEEDSHIFT DCT 7G transmission are rounded off with a temporary M mode activated by operating the steering wheel shift paddles in any driving mode, and with the manual transmission mode “M” for manual gear shifting with the shift paddles.
AMG Performance 4MATIC variable all-wheel drive
Dynamism, agility and performance – these three attributes characterize the standard all-wheel drive of the new AMG A 35 4MATIC. The variable AMG Performance 4MATIC combines the best possible traction with lots of driving fun. The torque distribution is infinitely variable to suit the dynamic handling requirements. The spectrum ranges from front-wheel drive only to a 50:50 percent distribution to the front and rear axles.
A multi-disc clutch that is integrated in the rear axle transmission is responsible for the variable torque distribution between the front and rear axles. It is controlled electro-mechanically. 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 sharper driving dynamics – primarily due to the significantly faster response and speed-independent actuation of the discs over the entire adjustment range.
As long as ESP is activated, the 4MATIC system stays in “Comfort” mode. As soon as the driver presses the “ESP SPORT Handling” or “ESP OFF” button, the 4MATIC system switches to “Sport” mode – for even more agile handling and even higher stability limits.
World premiere and market launch
The new Mercedes-AMG A 35 4MATIC will make its world premiere at the Paris Motor Show on 2 October 2018, sales will start in October 2018, and market launch will kick off in Q1 2019 in the UK.
