Introduction to the Mercedes-AMG A 35 4MATIC
A new entry-level hot hatch opens up the world of driving performance. Emotional, agile, and digital: with the AMG A 35 4MATIC, Mercedes is presenting a completely new entry-level model in the world of driving performance. Based on the new Mercedes front-wheel-drive platform, it is powered by a new 2.0-liter four-cylinder turbo engine with an output of 225 kW (306 hp). Every detail, from the body shell and suspension to the all-wheel drive, transmission, driving programs, and fine-tuning, has been designed for maximum driving dynamics without compromising on everyday comfort. The performance at sports car level (acceleration from 0-100 km/h in 4.7 seconds) and the specific design also strengthen its identity as a member of the performance family. A true AMG for the Hot Hatch stage.
Development and AMG DNA Integration
The new AMG A 35 4MATIC expands the AMG model portfolio as an attractive entry-level model in every respect. The development of the AMG A 35 4MATIC was integrated into the development process of the new Mercedes-Benz A-Class right from the start, alongside the future A 45 4MATIC. This allowed the AMG DNA to be injected into every relevant detail, resulting in an authentic driving performance that can be experienced by the driver.
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 “shear panel,” a bolted aluminum 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 stiffness.
2.0-Liter Turbo Engine
The 2.0-liter turbo engine is a new development 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 aluminum reduces the vehicle weight where it matters most for driving dynamics.
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, each 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 backpressure is reduced, and gas exchange and engine efficiency are improved. The high technological standards of the new four-cylinder engine are also underscored by numerous efficiency-enhancing measures such as 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.
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 AMG 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 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 into 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 the “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.
AMG DYNAMIC SELECT Driving Programs
Five driving programs: vehicle characteristics with a widespread. The five AMG DYNAMIC SELECT driving programs “Slippery,” “Comfort,” “Sport,” “Sport +,” and “Individual” enable a wide range of vehicle characteristics from comfortable to dynamic. They change relevant parameters such as the response of the engine and transmission. The new “Slippery” drive program is optimized for slippery road conditions, with reduced power and a flat torque curve. Smooth gear changes, earlier upshifts, and the ECO start/stop system support the stability-focused driving impression. The “Comfort” program stands for comfortable and fuel-efficient driving, for example, thanks to very early upshifts. Suspension and steering are set up with an emphasis on comfort, and the ECO start/stop system is active. “Sport” and “Sport+” place the focus on agility and driving pleasure with a sporty engine and transmission tuning. The sound of the turbocharged engine becomes more distinctive. The ECO start/stop system is inactive. “Sport+” is particularly emotional with double-declutching during downshifts and partial cylinder cut-off via a brief and precisely defined retardation of ignition and injection at full load.
AMG DYNAMICS
AMG DYNAMICS: more agility with high stability. As a new feature in the AMG DYNAMIC SELECT driving programs, the new AMG A 35 4MATIC comes with AMG DYNAMICS. This integrated dynamic handling control system extends the stabilizing functions of ESP® with agilizing interventions according to the driver’s wishes. During dynamic cornering, imperceptible braking intervention on the rear inside wheel creates a defined yawing moment about the vertical axis. The effect: the AMG A 35 4MATIC steers spontaneously and very precisely. The different manifestations of AMG DYNAMICS are called “Basic” and “Advanced.” The drive program selection indicated on the multimedia display shows the new AMG DYNAMICS symbol with the relevant additional term.
AMG RIDE CONTROL Suspension
The AMG RIDE CONTROL suspension layout is based on the dimensional concept of the new Mercedes-Benz A-Class with good straight-line stability and highly dynamic cornering behavior. The longitudinal and transverse dynamics are perfectly coordinated. A McPherson suspension strut construction maneuvers on the front axle. A suspension is taken care of by one wishbone below the wheel center, one spring strut, and one tie rod respectively. The special axle geometry reduces the influence of the drive on the steering – for high comfort and agile handling. The new wishbone in aluminum reduces the unsprung masses enabling a more sensitive response from the springs. The AMG-specific front steering knuckle has a radially bolted brake caliper – a technology originating from motorsport. The 4-link rear axle is connected rigid
