Following the Hot Hatch, the next level of driving performance is here: the A 35 4MATIC Saloon is the second model from Mercedes-AMG based on the new compact car platform and the first choice for customers looking for the sportiness typical of the brand combined with a comfortable amount of space for passengers and luggage. The exceptional driving dynamics of the agile notchback model are ensured by the 2.0-litre four-cylinder turbo engine with 225 kW (306 PS), the AMG SPEEDSHIFT DCT 7G dual-clutch transmission, the AMG suspension and the variable AMG Performance 4MATIC all-wheel drive.
The new A 35 4MATIC Saloon expands the current AMG model range by an additional attractive entry-level model. It appeals to young target groups who are looking for a high level of performance and a comfortable amount of space for passengers and luggage. An acceleration time of 4.8 seconds for 0–100 km/h and the top speed of 250 km/h (electronically limited) meet these customers’ requests for high driving dynamics also in the compact segment. “Following the very successful launch of the hatchback model, things are moving along dynamically in the compact class segment at AMG. Sport saloons are the origin of Mercedes-AMG and part of the brand’s core. With our new A 35, we are transporting this history into modern times in the form of a very attractive model that serves as a point of entry into the world of AMG and also appeals to new customer groups,” states Tobias Moers, CEO of Mercedes-AMG.
The front axle of the AMG suspension features a McPherson suspension strut construction. 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 the influence of the drive on the steering, the new wishbone in aluminium reduces the unsprung masses. The AMG-specific front steering knuckle has a radially bolted brake calliper – a technology originating from motorsport. The 4-link rear axle is connected rigidly with the body via a subframe. Three transverse arms and the trailing arm, the wheel carrier and the bearings from the proven A 45 4MATIC are used on each rear wheel. This ensures maximum driving stability and agility.
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 “shearing plate” – an aluminium plate underneath the engine – increases the torsional rigidity and bending resistance at the vehicle’s front end. Two additional diagonal braces at the front of the underbody also reduce torsion and increase the stiffness.
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 programme the driver has selected, it provides taut and sporty or more comfortable steering feedback. The rigid mounting in the integral carrier connects the steering even better with the body and thus increases steering precision.
Dynamism, agility and performance – these three attributes characterise the standard all-wheel drive of the new AMG A 35 4MATIC Saloon. 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.
