The new Mercedes-AMG GLA 45 4MATIC+: a compact performance SUV to suit any lifestyle

A brisk lap of the race circuit or a weekend trip to the mountains with your sports gear stowed in the back: the new GLA 45 4MATIC+ and GLA 45 S 4MATIC+ are the assured masters of a multitude of disciplines. When required, these compact all-rounders can unleash a level of dynamic handling to impress even sports car owners.

The 2.0-litre engine is the most powerful series-produced four-cylinder turbo engine in the world and is available in two output and torque versions. Even the base model delivering 387 hp is more powerful than the previous model. The S-variant rated at 421 hp jostles with considerably higher vehicle classes. The active, fully-variable AMG Performance 4MATIC+ all-wheel drive distributes the power to the rear axle wheel-selectively by AMG TORQUE CONTROL, so providing the basis for top traction in any driving conditions. This is made possible by a new rear axle differential featuring two multi-disc clutches – one for each rear wheel. The AMG SPEEDSHIFT DCT 8G dual clutch transmission apportions the power within a split second to suit the specific driving situation.

“The second generation of our very successful compact sports model is now complete. The GLA portfolio, in the form of the Mercedes-AMG GLA 45 and GLA 45 S, now also includes our innovative four-cylinder turbo engine, so setting the benchmark in this segment. In addition, the new GLA 45 is not only significantly more dynamic, but also more practical in everyday use than its predecessor, thereby ensuring its appeal to a dynamic, lifestyle-oriented target group”, says Tobias Moers, Chairman of the Board of Management of Mercedes-AMG .

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 improved on the output of the preceding engine by 40 hp. Maximum torque has also increased, from 475 to as much as 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 new compact sports cars absolve the sprint from zero to 100 km/h in record time: the GLA 45 S 4MATIC+ requires just 4.3 seconds, while the base model GLA 45 4MATIC+ gets up to speed in 4.4 seconds. The top speed of the base model is electronically limited to 250 km/h, while the S-Model is allowed to leave the factory with a top speed of 270 km/h.

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 base version) is available in a range of 5000-5250 rpm (4750-5000 rpm in the base version). With this configuration the AMG engineers have achieved a power delivery akin to a naturally aspirated engine.

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.

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 multi-disc clutches, each of which is connected to a rear axle drive shaft. In this way, the power can not only be variably distributed between the front and rear wheels, but also selectively between the left and right rear wheel. The result is consistently optimum traction, even in adverse road conditions and during extreme cornering manoeuvres, for example on the racetrack.

Athletic and muscular exterior

The exterior of the new GLA 45 also packs plenty of emotional appeal: the long bonnet with its powerdomes, the compact greenhouse and the muscular shoulders over the wheel arches clearly reveal the vehicle’s sports car genes. The AMG-specific radiator grille with the vertical slats identifies the newcomer as a member of the AMG Performance family. The front splitter in silver chrome serves to optimise the airflow and thus aerodynamic performance.

In side view, the aerodynamically optimised 19-inch light-alloy wheels in a 10-spoke design (S-Model 20-inch wheels in a 5-twin-spoke design) and the door panels with inserts in silver chrome or high-gloss black (optional) are particularly striking. As an option, this compact Performance SUV can also be fitted with 21-inch light-alloy wheels.

The rear view is characterised by two round twin tailpipes and the wide rear apron. The S-Model is distinguished by its larger, oval exhaust tailpipes, which feature 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.

Close alliance between man and machine in the interior

With its sporty appointments and the MBUX infotainment system, the high-quality interior creates a close, personal alliance between man and machine. The driver and front passenger are seated in an active position on contoured sport seats with firm lateral support. AMG Performance seats may be ordered as an option. The standard upholstery in a combination of black ARTICO man-made leather and DINAMICA microfibre is timeless, and creates typical AMG highlights with double topstitching in red. The red designo seat belts are coordinated to match, as is the AMG carbon fibre-look trim element in the dashboard support. 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. There is also an optional choice of four different leather upholsteries.

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. Emotively 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.

And needless to say, the trailblazing voice control activated with the words “Hey Mercedes” is also on board. Thanks to artificial intelligence, MBUX recognises and understands nearly all sentences from the fields of infotainment and vehicle operation, even if they are expressed indirectly.

Sound and audio experience

The AMG exhaust system confirms the sporty yet day-to-day character of the new model. Depending on the choice of drive program, the sound signature ranges from harmonious and discreet (in the programs Slippery, Comfort and Sport) to emotive and sporty (in Sport+ and RACE). The sound characteristics are controlled by an exhaust gas flap, depending on engine speed and load. AMG Real Performance Sound is available as an option. With this technology, the sound designers at AMG have been able to capture the actual engine sound, using a specially developed sensor, and to channel this into the interior in order to be able to offer an even more thrilling audio experience.
