Active AMG Performance.

Outstanding performance, the ultimate driving dynamics, expressive design – the new Mercedes-AMG compacts A 45 4MATIC+/A 45 S 4MATIC+ sports cars and CLA 45 4MATIC+/CLA 45 S 4MATIC+ reassert their leading positions in their segments. They seamlessly continue the success story of their predecessors, while setting numerous new standards. Available in two output and torque variants, the completely newly developed 2.0-litre engine is the world’s most powerful turbocharged four-cylinder engine manufactured for series production. Even the basic model with 285 kW (387 PS) is more powerful than its predecessor. The S-variant with 310 kW (421 PS) jostles with considerably higher vehicle classes. Perfect sequences in all driving situations and fast gearshifts measured in milliseconds are guaranteed by the new AMG SPEEDSHIFT DCT 8G dual-clutch transmission with eight gears. The active, fully-variable AMG Performance 4MATIC+ all-wheel drive distributes the power to the rear axle wheel-selectively by AMG TORQUE CONTROL – for top traction and the spectacular Drift mode. This is made possible by a new rear axle differential featuring two multidisc clutches – one for each rear wheel.

Demonstrating high competence.

With its new compact sports models Mercedes-AMG is demonstrating its high competence in development once again: “We have completely redesigned our 45 models – from the engine and transmission through the chassis, the elaborately constructed drivetrain to the body structure and of course the design itself – all with one goal: to raise vehicle dynamics and the sporty driving experience to a level previously unimaginable in the compact class. With the presentation of this, our most powerful and most dynamic compact sports car, we are also reinforcing the significance of this segment for our growth strategy,” says Tobias Moers, Chairman of the Management Board of Mercedes-AMG GmbH.

Exterior design: AMG family membership.

The new Mercedes-AMG A 45 4MATIC+ and CLA 45 4MATIC+ models are even more distinctive than their predecessors. The exterior conveys sheer driving pleasure even at standstill. 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 the 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.

Drive system: new turbocharged four-cylinder.

With an output of up to 310 kW (421 PS), the completely 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 30 kW (40 PS). Maximum torque has also increased from 475 to up to 500 newton metres. With an output per litre of up to 155 kW (211 PS), the new Mercedes-AMG high-performance turbo engine even ranks ahead of many well-known super sports car engines. The new, highly efficient powerpack is produced on an innovative production line in Affalterbach, Germany, on the “One Man, One Engine” principle.

In the 45 models, the four-cylinder ensures extremely agile performance in two output classes: with 310 kW (421 PS) as the S-model and with 285 kW (387 PS) 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 sports cars 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+: 4.0 seconds), while the basic A 45 4MATIC+ model absolves this discipline in 4.0 seconds (CLA 45 4MATIC+ in 4.1 seconds). The top speed of the basic models is electronically limited to 250 km/h, while the S-models are capable of up to 270 km/h ex factory. With the optional AMG Driver’s Package, the top speed can also be increased to 270 km/h for the basic variants.

Engine design: intelligent details.

The new engine excels with numerous intelligent design features. Unlike the likewise transversely installed four-cylinder in the preceding models, the new engine is rotated around its vertical axis by 180 degrees. This means that the turbocharger and the exhaust manifold are now positioned at the rear, on the side of the firewall when viewed from behind. The intake system is therefore positioned at the front. This configuration allows the flattest possible and aerodynamically advantageous front section design. Furthermore, the new arrangement allows much improved air ducting with shorter distances and fewer diversions – both on the intake and exhaust side.

Petrol injection: two stages for optimised power.

Turbocharging and direct injection with a spray-guided combustion process not only allow a high power yield, but also improve thermodynamic efficiency and therefore reduce both fuel consumption and exhaust emissions.

For the first time, the new high-performance four-cylinder has two-stage fuel injection. In the first stage the particularly fast and precisely operating piezo injectors supply fuel to the combustion chambers at a pressure of up to 200 bar. This is a multiple process at times, and is controlled by the engine management system as required.

In the second stage there is additional intake manifold injection using solenoid valves. This is needed to achieve the engine’s high specific output. The electronically controlled fuel supply has an operating pressure of 6.7 bar.

AMG SPEEDSHIFT DCT 8G dual-clutch transmission.

The 8-speed AMG SPEEDSHIFT DCT 8G dual-clutch transmission likewise contributes to the agile and dynamic character. 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. Depending on the selected AMG DYNAMIC SELECT driving mode, the driver receives a specific drive configuration with different accelerator and gearshift characteristics.

AMG Performance 4MATIC+ all-wheel drive.

The extremely 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.

Interior: close symbiosis between man and machine.

With its sporty appointments and the MBUX infotainment system, the high-quality interior creates a close, personal connection between man and machine. The driver and front passenger are seated in an active position on contoured sport seats with firm lateral support. The standard upholstery as a combination of black ARTICO man-made leather and DINAMICA microfibre is timeless, and creates typical AMG highlights with double topstitching in red. The colour scheme is echoed by the red designo seat belts and the dashboard support trim in black DINAMICA microfibre with a red border. The chromed air vents are likewise upgraded with a red ring. As an alternative an upholstery in ARTICO man-made leather in neva grey/black with mid-grey double topstitching and light-longitudinal-grain aluminium trim is available.

MBUX infotainment system: with AMG-specific displays.

The combination of sporty design and sophisticated details is also featured in the MBUX infotainment system with its innovative operating and display concept. MBUX creates an even closer connection between the vehicle, driver and passengers. Emotionally appealing presentations underline the clear control structure and feature brilliant maximum-resolution 3D graphics. Visually, the two displays under one shared glass cover blend into a Widescreen Cockpit and as a central element consequently emphasise the horizontal orientation of the interior design.
