The new Mercedes-AMG CLA 45 4MATIC+ Shooting Brake: A model athlete for all eventualities

Mercedes-AMG presents the CLA 45 4MATIC+ Shooting Brake and the CLA 45 S 4MATIC+ Shooting Brake – two powerful new compact cars that complement sporty athleticism with wide-ranging functionality. The 2.0-litre four-cylinder turbo engine is more powerful than ever, with an output of 387 hp or 421 hp. The combination of extremely sporty performance (acceleration 0-62 mph in 4.1/4.0 seconds) and the variable interior with increased luggage capacity is aimed at a young target group who lead an active and varied life at work and in their leisure time.

One new feature which makes a substantial contribution to the incomparable driving experience is the active, fully variable AMG Performance 4MATIC+ all-wheel drive: for the first time, this system offers selective power distribution to the wheels on the rear axle via AMG TORQUE CONTROL. This means that the power is distributed to the left and right rear wheels highly flexibly and at different ratios, according to the given driving situation – resulting in optimum traction, whatever the road surface conditions and whatever course the route takes. In addition, spectacular Drift mode (standard on the S-Model, included in the optional AMG DYNAMIC PLUS package for the base model) provides for even greater driving enjoyment. This is made possible by a newly developed rear axle differential, which for the first time incorporates two multi-plate clutches. These open and close at lightning speed to control the torque flow for each rear wheel individually.

Athletic and muscular exterior design

The exterior of the new CLA 45 Shooting Brake also packs plenty of emotional appeal: the long bonnet, the greenhouse with coupé-style window line, the muscular shoulders over the wheel arches and the low rear clearly reveal the vehicle’s sports car genes. The AMG-specific radiator grille with the vertical slats unmistakably identifies the Shooting Brake as a member of the AMG Performance family. At the same time, the “shark nose”, the sharply defined, narrow headlamps and the flat, aerodynamic bonnet lend the front a crouched appearance.

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. The nozzle-shaped outer air intakes establish a close link to the AMG GT 4-Door Coupé. The front splitter transitions seamlessly into the side air curtains ahead of the front wheels, which optimise the airflow to improve aero-performance and the Cd figure.

The rear view is characterised by two round twin tailpipes and the wide rear apron. The S-Models are distinguished by their larger, 90 mm exhaust tailpipes with internal fluting and AMG lettering. The impression of width at the rear is emphasised further by the slim two-piece rear light clusters. The diffuser with four vertical fins contributes to the enhanced aerodynamic performance. The airflow break-away edge in the body colour on the roof spoiler rounds off the profile to the rear.

At 871 millimetres, the boot opening is significantly wider than in the previous model (635 mm). In addition, the tailgate can also be opened contactlessly with EASY PACK and HANDS-FREE ACCESS. At 505 litres, the boot is large enough to accommodate a wealth of recreational and outdoor equipment.

New four-cylinder turbo engine delivering superlative power

With an output of up to 421 hp, the completely new Mercedes-AMG 2.0-litre engine is currently the world’ s most powerful turbocharged four-cylinder manufactured for series production. Mercedes-AMG has bettered the output of the preceding engine by 40 hp. Maximum torque has also increased from 475 to up to 500 newton metres. The new, highly efficient powerpack is produced on an innovative production line in Affalterbach, on the “One Man, One Engine” principle.

The four-cylinder engine delivers extremely agile drive power in two output ratings: with 421 hp as the S-Model and with 387 hp in the basic version. The new compact sportscars absolve the sprint from zero to 0-62 in record time: the CLA 45 S 4MATIC+ Shooting Brake requires just 4.0 seconds, while the base model CLA 45 4MATIC+ Shooting Brake gets up to speed in 4.1 seconds. The top speed of the base model is electronically limited to 155mph, while the S-Model leaves the factory with a top speed of 167mph. With the optional AMG Driver’s package, the base variant can also driven at up to 167mph

Apart from its performance figures, the new engine impresses with its immediate response. To this end the torque curve was carefully balanced (“torque shaping”): The peak torque of 500 newton metres (480 newton metres for the basic version) is available in a range of 5000-5250 rpm (4750-5000 rpm in the basic version). With this configuration the AMG engineers have achieved a power delivery akin to a naturally aspirated engine.

Electronically controlled charge-air pressure

With a maximum charge pressure of 2.1 bar, the 2.0-litre four-cylinder turbo engine is also the leader in its segment in this respect. The electronically controlled wastegate (exhaust relief valve) allows the charge pressure to be controlled even more precisely and flexibly while optimising responsiveness, especially when accelerating from partial load. Numerous parameters are taken into account in this process.

Fresh air is used in addition to oil and water to cool the turbocharger. This is directed specifically to the charger from the radiator grille, via the engine cover designed as an air deflector and ducts beneath the bonnet. In addition the turbine housing has integral insulation.

Agile 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.

The standard RACE-START function allows maximum acceleration from stationary, a highly emotional experience. 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. 

AMG Performance 4MATIC+ all-wheel drive with AMG TORQUE CONTROL

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 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 drive mode, the traction 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.

Adaptive damping system AMG RIDE CONTROL with three modes

The optional AMG RIDE CONTROL adaptive damping system enables the driver to choose between three different suspension control modes. The spectrum ranges from comfort-focused to sporty. The system operates fully automatically, adapting the damping forces for each wheel according to the driving situation and road conditions. This happens within milliseconds and is infinitely variable, with a wide spread of damping characteristics. The result is that it ride comfort and agility are enhanced in equal measure.

Robust high-performance brake system

The high-performance braking system ensures fade-resistant deceleration and short braking distances. On the base model, the 4-piston monobloc fixed front callipers act on 350 x 34 millimetre brake discs, while at the rear axle, 1-piston floating callipers act on 330 x 22 millimetre brake discs. The discs are internally ventilated and perforated to better dissipate heat and prevent brake fading, even with extreme use. The grey-painted brake callipers have white AMG lettering.

The S-Model and the base model with the optional AMG DYNAMIC PLUS package are decelerated by an even larger braking system equipped with 6-piston fixed callipers and 360 x 36 millimetre brake discs at the front. In this case the brake callipers are painted red and bear a black AMG logo.

Man and machine in close alliance

ith 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.
