Unveiling the Sound Character of the A 45s
The Mercedes-AMG A 45s sound showcases the impressive exhaust notes of this hot hatch. With a powerful 422 hp engine, the sound experience is both deep and engaging.
The Powertrain of the Mercedes-AMG A 45s
The Mercedes-AMG A 45s is powered by a turbocharged 2.0-litre inline-4 engine, designated as the M139. This engine produces a remarkable 422 horsepower and 500 Nm of torque, paired with an 8-speed AMG SPEEDSHIFT DCT transmission. The A 45s features the advanced 4MATIC+ all-wheel-drive system, enhancing traction and stability.
Cold Start and Idle Sounds
Upon starting, the A 45s delivers a throaty growl that signals its performance pedigree. The sound is richer than previous generations, yet still adheres to modern EU regulations that limit exhaust volume. The cold start showcases a deep tone that resonates, providing a hint of the power that lies beneath the hood.
Acceleration and Throttle Response
As the engine warms up, the exhaust note transitions to a more aggressive tone. Blips of the throttle reveal a crisp and responsive character, with noticeable pops and crackles during rapid acceleration. The dual-clutch transmission contributes to seamless gear changes, allowing the driver to experience the full orchestration of sounds as the A 45s accelerates from idle to its impressive top speed of 270 km/h.
Driving Sounds
While on the move, the A 45s maintains a deep and pleasant sound profile. The exhaust note remains satisfying without being overly loud, reflecting the balance that AMG has struck under current regulations. The variable torque distribution of the 4MATIC+ system enhances the driving experience, giving rise to a symphony of sounds that underscore the car's agility and speed.
Comparing to Rivals
When compared to its closest rivals, the A 45s stands out not only for its power but also for the unique sound character it offers. Unlike many competitors, the M139 engine’s high specific output contributes to a distinctive audio signature that is both sporty and refined. While many hot hatches capture attention with sheer volume, the A 45s focuses on a well-rounded sound experience that complements its performance capabilities.
In conclusion, the 2019 Mercedes-AMG A 45s delivers a captivating sound experience that matches its impressive performance metrics. With a blend of deep tones and aggressive exhaust notes through various driving conditions, it sets a benchmark for hot hatches in its class.
