Mercedes-AMG A 34 4Matic
The world premiere presentation was at the Paris Motor Show, while orders will be ready in October, with the first deliveries scheduled for the end of January 2019.
Developed in parallel to the less performing versions of the new A-Class, the 35 features chassis reinforcements designed to stiffen the structure and improve driving precision. Underneath the engine an aluminum panel has been bolted, which, together with two diagonal arms, improves the torsional stiffness of the front section. The structure has also been revised and now has rear arms derived from the previous generation A 45 and a MacPherson front axle with specific steering joints and four-piston monobloc radial calipers with 350 mm perforated and ventilated discs. The Adaptive Damping System is available on request, an electronically adjustable trim that allows the driver to select three different settings. The system is able to automatically change the parameters of each individual shock absorber in just a few milliseconds to provide maximum performance in any situation without affecting driving comfort. Finally, there is a specific parametric electromechanical power steering that varies its response depending on the speed and driving mode selected among the five available on the AMG Dynamic Select which, for the first time, features AMG Dynamics, a system that adjusts the operation of the SP according to the driving program.
While sharing the displacement of 1,991 cm3 with the previous M133 of the AMG A 45, the new two-liter turbo comes from a different project. Inside the bonnet of the A 35 is in fact an advanced version of the four cylinder M260, introduced right on the new A 250 224 hp. Compared to its younger sister, the AMG version features a twin-scroll turbine with two separate ducts, each of which is used for the supercharging of two cylinders. This makes it possible to improve efficiency and reduce back pressure of exhaust gases, which are expelled through a new valve system. The four-cylinder thus delivers 306 bhp between 5,800 and 6,100 rpm with a maximum torque of 400 Nm available between 3,000 and 4,000 rpm. The seven-speed automatic transmission AMG Speedshift Dct 7G is offered as standard with a Race Start function combined with the AMG Performance 4Matic all-wheel drive system with torque distribution controlled by a multi-disc clutch integrated into the rear axle. With these features the compact sport can shoot from 0 to 100 km / h in 4.7 seconds (five tenths more than 45) and reach a top speed electronically limited to 250 km / h: the declared consumption is between 7 , 3 and 7.4 l / 100 km with CO2 emissions between 167 and 169 g / km. As usual, the mechanical modifications are combined with different aerodynamic news on the bumpers, now equipped with new air intakes, flic, splitter and, at the rear, a spoiler combined with an extractor with integrated drains. Inevitably, the interiors have also been updated with new seats upholstered in faux leather and microfibre with contrast stitching and red belts. As standard, a digital instrument panel combined with the MBUX system with specific functions, such as telemetry with optional data logger, and a new generation sports steering wheel with touch control buttons are also included. On request, below the horizontal spokes, there is also a rotary selector with integrated display for driving modes combined with a pair of small screens that act as configurable buttons to access the various functions of the car more quickly.
