Mercedes-Benz GLA 45 AMG

All-Rounder with Driving Performance

Affalterbach – Mercedes-AMG rigorously continues its product initiative: with the new Mercedes-Benz GLA 45 AMG the performance brand of Mercedes-Benz makes a dynamic statement in the strongly growing segment of the compact SUV. The combination of powerful-distinctive design, exclusive appointments as well as superior engine power and driving performance is unique: the most powerful series-production four-cylinder engine in the world puts 265 kW of power and 450 Newton metres of torque on the road. The new Mercedes-Benz GLA 45 AMG high-performance SUV also shines with regard to emissions and fuel consumption figures.

With a fuel consumption of 7.5 litres per 100 kilometres (NEDC combined; CO2: 175 g/km) and compliance with EU 6 emissions standards the Mercedes-Benz GLA 45 AMG once more provides proof that at Mercedes-AMG maximum performance does not come at the expense of environmental compatibility. The Mercedes-Benz GLA 45 AMG also holds the pole position with regard to driving dynamics: it accelerates from zero to 100 km/h in 4.8 seconds and reaches a top speed of 250 km/h (electronically limited). Thanks to the combination of standard-fit performance-oriented AMG 4MATIC all-wheel-drive and the AMG SPEEDSHIFT DCT 7-speed sports transmission, the Mercedes-Benz GLA 45 AMG impresses with its equally sporty and efficient drive system concept.

Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH: “The response to the Concept Mercedes-Benz GLA 45 AMG during the world première at the Los Angeles International Auto Show has reaffirmed our decision to launch this new AMG model. Currently there is no segment growing faster than that of compact SUVs. For Mercedes-AMG it is therefore a logical step to make a dynamic statement in this segment with the Mercedes-Benz GLA 45 AMG. Our new high-performance-SUV not only offers the world’s most powerful series-production four-cylinder engine, but also impressively low fuel consumption and emissions figures. Not least on account of the performance-oriented AMG 4MATIC all-wheel drive, the Mercedes-Benz GLA 45 AMG is a true AMG when it comes to driving dynamics”.

Young target group: styling, dynamics and independence

In addition to the A 45 AMG and CLA 45 AMG, the Mercedes-Benz GLA 45 AMG is the third vehicle with four-cylinder turbo engine to appeal to a young target group. The trend-oriented customers set great store in styling, dynamics and independence – traits that are perfectly embodied in the new high-performance SUV from Affalterbach. Meeting a wide variety of customer desires has always been one of the strengths of Mercedes-AMG. The Mercedes-Benz GLA 45 AMG now expands the extensive SUV line-up to five models (Mercedes-Benz GLA 45 AMG, ML 63 AMG,
GL 63 AMG, G 63 AMG and G 65 AMG). Mercedes-AMG thus offers the
widest range of SUVs among all high-performance premium brands.

Hallmark AMG features: the world’s most powerful series-produced four-cylinder engine

Best in class: the engine of the Mercedes-Benz GLA 45 AMG fully lives up to this claim, as a look at the figures shows. The AMG 2.0-litre turbo engine is the most powerful series-production four-cylinder turbo engine in the world. It produces 265 kW of power and develops a peak torque of 450 Newton metres. A power density of 133 kW puts the AMG high-performance turbo engine on a par with the world’s most powerful super sports cars.

Key data at a glance:

Mercedes-Benz GLA 45 AMG
Displacement 1991 cc
Bore x stroke 83.0 x 92.0 mm
Output 265 kW at 6000 r/min
Max. torque 450 Nm at 2250-5000 r/min
Power density 133 kW
Fuel consumption, NEDC combined 7.5 l/100 km
CO2 emissions 175 g/km
Emissions standards EU 6
Acceleration 0-100 km/h 4.8 sec
Top speed 250 km/h*

* Electronically limited

Development of the high-performance turbo engine, which is part of the BlueDIRECT family, placed emphasis on a sustainable reduction in particulate emissions. Consequently the Mercedes-Benz GLA 45 AMG today already complies with the second stage of the EU 6 emissions standards coming into effect in 2017. The AMG 2.0-litre four-cylinder turbo engine features spray-guided direct petrol injection with piezo injectors positioned centrally in the four combustion chambers and an injection pressure of 200 bar. The combination of multiple fuel injection and multiple spark ignition improves fuel economy and significantly increases the thermodynamic efficiency, leading to low exhaust emissions. The injection system’s outstanding flexibility also ensures a high degree of freedom in terms of application. There are up to five injections per combustion cycle in the cold-start and warm-up phase, which is so crucial for emissions. One of the key factors for in-engine particulate reduction is a reduction of the individual injection quantities.

Further highlights of the AMG 2.0-litre four-cylinder turbo engine:

  • Gravity-die sand-cast all-aluminium crankcase
  • Weight-optimised crank mechanism with forged steel crankshaft
  • Forged pistons with friction-optimised piston rings
  • NANOSLIDE cylinder liner technology
  • Air-to-water intercooling system
  • Alternator management
  • ECO start/stop function

Twin-scroll turbocharger and AMG sports exhaust system with
exhaust flap

Mercedes-AMG addresses the basic challenge with regard to the throttle response of a small-capacity turbo engine by using a twin-scroll turbocharger, maximum dethrottling of the exhaust system and an innovative injection strategy. Twin-scroll technology provides for a more spontaneous build-up of charge pressure: Utilisation of the exhaust back-pressure, exhaust-gas temperature and exhaust-gas pulse has a positive impact. This results in a faster build-up of torque already at low engine speeds. A positive side-effect: fuel consumption and exhaust emissions also benefit from twin-scroll technology. With a maximum charge pressure of 1.8 bar, the AMG 2.0-litre four-cylinder turbo engine leads the field on this front, too.
