Top marks in all disciplines
The A 45 AMG and the CLA 45 AMG see Mercedes-AMG embarking on a new era. For the first time in the company’s history extending back over more than 45 years, Mercedes-Benz’s performance brand is offering two high-performance cars powered by a four-cylinder engine. Both new models provide an exciting introduction to the world of AMG. With an output of 265 kW (360 hp) and a peak torque of 450 Nm (332 lb-ft), the AMG 2.0-litre turbo engine is the world’s most powerful four-cylinder engine in series production. It is also exceptionally efficient and meets the requirements of the EU6 emissions standards. NEDC combined fuel consumption of 6.9 l/100 km (34.08 mpg/US, 14.49 km/l) puts the A 45 AMG and CLA 45 AMG at the top of their segments. Performance-oriented AMG 4MATIC all-wheel drive sets new standards in dynamic handling.
The A 45 AMG and CLA 45 AMG offer a fascinatingly sporty driving experience, characterised by impressive craftsmanship and individuality. Both new four-cylinder models feature the hallmark AMG DNA, of course, largely down to the fact that during design and development the Mercedes-AMG experts were able to draw on all their experience in motorsport and the construction of powerful high-performance cars and components gained over the past decade. BlueDIRECT turbo engine, all-wheel drive and AMG SPEEDSHIFT DCT 7-speed sports transmission – the A 45 AMG and CLA 45 AMG boast an extremely attractive, dynamic and efficient drive configuration.
With ages ranging between 30 and the mid-40s, the A 45 AMG and CLA 45 AMG target groups are younger than the previous AMG customers. Professionally successful and independent, the customers are looking for dynamic and individual cars. Their wish is to express their style- and trend-driven lifestyle with a car from a recognised performance brand. The A 45 AMG is an agile and emotive high-performance car for these target customers, who prefer to live in an urban environment. The CLA 45 AMG follows the philosophy of the successful CLS 63 AMG – the trend-setting four-door high-performance coupé. It offers a unique combination of a fascinatingly sporty driving experience, extravagant design and maximum individuality. Mercedes-AMG appeals to the tech-savvy and flexible attitude to life adopted by both target groups by offering a wide range of equipment, colour and material options for the new models.
Two figures show that the A 45 AMG and CLA 45 hold pole position in their displacement segment: the newly developed AMG 2.0-litre turbo engine is the most powerful series-production four-cylinder turbo engine in the world. A maximum output of 265 kW (360 hp) and up to 450 Nm (332 lb-ft) of torque are unmatched by any other mass-produced turbocharged four-cylinder engine worldwide. The power density of 133 kW (181 hp) puts the AMG high-performance turbo engine on par with the world’s most powerful super sports cars.
The high output and torque coupled with the performance-oriented AMG 4MATIC all-wheel drive fitted as standard make for extremely dynamic performance: both the A 45 AMG and the CLA 45 AMG complete the sprint from 0 to 100 km/h (62 mph) in 4.6 seconds and have a top speed of 250 km/h/155 mph (electronically limited). With a fuel consumption of 6.9 l/100 km (34.08 mpg/US, 14.49 km/l) (NEDC combined), the new high-performance cars from Affalterbach are exceptionally efficient and lead the way in their segments. A further priority when developing both models was to ensure a sustainable reduction in particulate emissions. The A 45 AMG and the CLA 45 AMG thus already comply with the second stage of the EU6 emissions standards that do not go into effect until 2017.
The basis for these impressive figures is provided by the high-tech package put together by Mercedes-AMG. As a high-performance engine belonging to the BlueDIRECT family, the AMG 2.0-litre four-cylinder turbo engine features spray-guided direct petrol injection via piezo injectors positioned centrally in the four combustion chambers with an injection pressure of 200 bar. The combination of multiple fuel injection and multiple spark ignition improves fuel utilisation and increases thermodynamic efficiency substantially, leading to low exhaust emissions. The A 45 AMG and the CLA 45 AMG thus already comply with the second stage of the EU6 emissions legislation that does not go into effect until 2017. The injection system’s outstanding flexibility also ensures a high level of degrees of freedom for the application. There are up to five injections per combustion cycle in the cold-start and warm-up phase that is so crucial in terms of emissions. Here one of the key aspects for in-engine particulate reduction is the reduction of the partial injection quantities.
Other highlights include: gravity-die sandcast all-aluminium crankcase, weight-optimised crank assembly with forged steel crankshaft and forged pistons with friction-optimised piston rings, NANOSLIDE cylinder wall technology, air-to-water intercooler, alternator management and ECO start/stop function.
