With its new compact sports models Mercedes-AMG is demonstrating its competence in development once again. The new Mercedes-AMG A 45 4MATIC+ and CLA 45 4MATIC+ models are even more distinctive than their predecessors.
For the first time, the compact class now also features the AMG-specific radiator grille with a wider lower contour and twelve vertical louvres – as a clear indicator of AMG Performance family membership. At the same time, the pronounced “shark nose”, the slim, deeply contoured headlamps and the flat, aerodynamically favourable bonnet with powerdomes visually lower the front section to create the impression of extremely dynamic forward thrust, says Mercedes-AMG.
The imposing presence is also accentuated by the wider front wings with flared wheel arches. These create space for the wider front axle, and underline the athletic appearance. This muscular impression is even stronger with the A 45 4MATIC+ than with the CLA 45 4MATIC+, as the basic CLA already has a wider front track and the wings could be flared to a lesser extent.
With an output of up to 310kW, the newly developed 2.0-litre engine is the world’s most powerful turbocharged four-cylinder manufactured for series production. Mercedes-AMG has bettered the output of the preceding engine by 30kW. Maximum torque has also increased from 475Nm up to 500Nm. With an output of 155kW/litre, the new Mercedes-AMG high-performance turbo engine ranks with the best in the world.
In the 45 models, the four-cylinder ensures extremely agile performance in two output classes: with 310kW as the S-model, and with 285kW in the basic version.
This positioning logic has already proved successful for the AMG Performance models with a V8 engine, and meets individual customer wishes even better. The new compact sportscars absolve the sprint from zero to 100 km/h in record time: the A 45 S 4MATIC+ requires only 3.9 seconds (CLA 45 S 4MATIC+: 4.0sec), while the basic A 45 4MATIC+ model absolves this discipline in 4.0sec (CLA 45 4MATIC+ in 4.1sec). The top speed of the basic models is electronically limited to 250km/h, while the S-models are capable of up to 270km/h. With the optional AMG Driver‘s Package, the top speed can also be increased to 270km/h for the basic variants.
The eight-speed AMG SPEEDSHIFT DCT 8G dual-clutch transmission likewise contributes to the character of each car. 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, according to Mercedes-AMG. Depending on the selected AMG DYNAMIC SELECT driving mode, the driver receives a specific drive configuration with different accelerator and gearshift characteristics.
Anyone who prefers to change gear for themselves can select the manual transmission mode in every drive program. Using the temporary M-mode, this is possible by operating a steering wheel shift paddle.
The standard RACE-START function allows maximum acceleration from stationary. This also applies to the drive sound with partial ignition interruption when changing up a gear, and the automatic double-declutching function when changing down. Neither is efficiency neglected: in “Comfort” mode the ECO start/stop function is active; the “gliding” function can be selected in the “Individual” driving mode.
The dynamic driving experience in a completely new dimension is greatly assisted by the fully variable all-wheel drive included as standard. The secret is AMG TORQUE CONTROL in the new rear axle differential: This has two electronically controlled multidisc clutches, each of which is connected to a rear axle drive shaft. In this way the drive power can not only be completely variably distributed between the front and rear wheels, but also selectively between the left and right rear wheel. This means that depending on the driving mode and situation, the drive torque can be separately distributed to both rear wheels.
The result is consistently optimum traction, even in adverse road conditions and during extreme cornering manoeuvres, for example on the racetrack. Furthermore, this sophisticated solution allows Drift mode (standard in the S-models, included in the optional AMG DYNAMIC PLUS package for the basic models), which makes “powersliding” possible for even more driving pleasure.
Drift mode can be called up in the “RACE” driving mode using the shift paddles, provided that ESP® is deactivated and the transmission is in manual mode.
The new A 45 4MATIC+ and CLA 45 4MATIC+ will arrive in South Africa in due course. More detail and pricing will be announced closer to the time.
