GLA 45 AMG

All-Rounder with Driving PerformanceMercedes-Benz GLA 45 AMG (X 156) 2013

Mercedes-AMG rigorously continues its product initiative: with the new 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 (360 hp) of power and 450 Nm of torque on the road. The new 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 GLA 45 AMG once more provides proof that at Mercedes-AMG maximum performance does not come at the expense of environmental compatibility. The 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/155 mph (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 GLA 45 AMG impresses with its equally sporty and efficient drive system concept.Mercedes-Benz GLA 45 AMG (X 156) 2014

Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH: “The response to the Concept 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 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 GLA 45 AMG is a true AMG when it comes to driving dynamics.”

Young target group: styling, dynamics and independenceMercedes-Benz GLA 45 AMG (X 156) 2014

In addition to the A 45 AMG and CLA 45 AMG, the 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 GLA 45 AMG now expands the extensive SUV line-up to five models (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 engineMercedes-Benz GLA 45 AMG (X 156) 2014

Best in class: the engine of the 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 (360 hp) of power and develops a peak torque of 450 Nm (332 lb-ft). A power density of 133 kW (181 hp) puts the AMG high-performance turbo engine on a par with the world’s most powerful super sports cars.

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 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.GLA 45 AMG Motor (X 156) 2013

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 flapMercedes-Benz GLA 45 AMG (X 156) 2014

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.Mercedes-Benz GLA 45 AMG (X 156) 2014

The AMG sports exhaust system in the GLA 45 AMG features large pipe cross-sections and an automatically controlled exhaust flap: this technology reconciles the two conflicting goals of a dynamic driving experience and hallmark Mercedes suitability for long-distance driving. The flap in the rear silencer is continuously adjusted under map control according to the driver’s performance needs, load condition and engine speed. The two rectangular chrome-plated twin tailpipes on the AMG sports exhaust system emit a fascinating exhaust note, which is particularly impressive during powerful acceleration. An AMG Performance exhaust system, also equipped with an exhaust flap, is available as an optional extra.  Customers opting for this system will experience an even more appealing and distinctive engine sound.

Engine production – a tradition of hand-built excellenceMercedes-Benz GLA 45 AMG (X 156) 2014

The AMG 2.0-litre four-cylinder turbo engine is assembled purely by hand in accordance with the traditional AMG philosophy of “one man, one engine.” Apart from serving as an AMG hallmark confirming superlative production quality, the AMG engine badge bearing the engine fitter’s signature also attests the peerless DNA of Mercedes-Benz’s high-performance brand.

AMG SPEEDSHIFT DCT 7-speed sports transmissionMercedes-Benz GLA 45 AMG (X 156) 2014

The AMG SPEEDSHIFT DCT 7-speed sports transmission in the GLA 45 AMG features three distinct transmission modes, a double-declutching function dependent on the transmission mode and a RACE START function for optimum acceleration. The strengths of the dual-clutch transmission include spontaneous gear shifts without loss of tractive power, a tailor-made control strategy based on the AMG SPEEDSHIFT functions, extremely smooth gear shifts, and a high level of efficiency.Mercedes-Benz GLA 45 AMG (X 156) 2014

The shift times in manual mode “M” and in sport mode “S” are similarly sporty in character to those of the SLS AMG GT super sports car. Quick and precise retardation of the ignition and suppressing injection under full load lead to even faster gear shifts in “M” and “S” modes, with a more thrilling sound. The transmission control fully utilises the benefits of the direct injection technology right up to the physical limits: the quicker engine response ensures that injection is suppressed with even more precision. The effect: the shift speed and an emotional sound experience have strong potential to fascinate.Mercedes-Benz GLA 45 AMG (X 156) 2014

Another special feature designed to enhance dynamic performance and driving pleasure is the so-called “Momentary M mode” – as seen in the SLS AMG Coupé Black Series super sports car. In “C” mode (Controlled Efficiency), smooth transmission and engine characteristics support a fuel-efficient and comfort-oriented driving style. In addition, the ECO start/stop function is active in “C” mode.
