Digital and smart hand assembly “One man, one engine”
The new engine in this sleek Benz is entirely assembled by hand. To this end a completely newly designed production line was constructed in the AMG engine manufactory in Affalterbach, where Mercedes-AMG has raised the “One Man, One Engine” principle and Industry 4.0 processes to an innovative level reflecting the latest findings in ergonomics, material flows, quality assurance, sustainability and efficiency.
On the road to implementing Industry 4.0, AMG’s hand assembly operation likewise follows the vision of “smart production”.
Drive system: new turbocharged four-cylinder with ample power
With an output of up to 421 hp, the completely newly developed 2.0-litre engine is the world’s most powerful turbocharged four-cylinder manufactured for series production.
Mercedes-AMG has bettered the output of the preceding engine by 40 hp. Maximum torque has also increased from 475 to up to 500 newton metres. With an output per litre of up to 211 hp, the new Mercedes-AMG high-performance turbo engine even ranks ahead of many well-known super-sports car engines. The new, highly efficient power-pack is produced on an innovative production line in Affalterbach, on the “One Man, One Engine” principle.
This positioning logic has already proved successful for the AMG Performance models with a V8 engine, and meets individual customer wishes even better.
The new compact sports cars absolve the sprint from zero to 100 km/h in record time: the A 45 S 4MATIC+ requires only 3.9 seconds (CLA 45 S 4MATIC+: 4.0 seconds), while the basic A 45 4MATIC+ model absolves this discipline in 4.0 seconds (CLA 45 4 MATIC+ in 4.1 seconds).
The top speed of the basic models is electronically limited to 250 km/h, while the S-models are capable of up to 270 km/h ex factory. With the optional AMG Driver‘s Package, the top speed can also be increased to 270 km/h for the basic variants.
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 maximum torque of 500 Nm.
The engine developers were able to realize a dynamically increasing torque curve in the lower engine speed range, thereby improving throttle response. The increasing torque at higher rpm makes the engine more free-revving. Moreover, the high maximum engine speed (up to 7200 rpm) emphasizes the engine’s sporty character.
