Best in class: the engine of the Mercedes-Benz GLA45 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 Newton metres. 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 GLA45 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.
