There have been discussions about whether Mercedes-Benz amplifies the engine sounds in their cars. Some customers have noticed that their cars sound incredible, way better than what the engine would typically sound like. Mercedes-Benz did consider giving the EQS Electric Sedan a fake engine sound but decided against it. However, customers can choose from three soundscapes that are digitally produced noises meant to fill the void of an internal combustion engine. Some Mercedes models, such as the AMG, have a feature called Active Sound Design, where fake engine noises are pumped through the speakers. Customers can disable this feature by customizing their drive mode or taking their car to a dealer.

What You'll Learn
Fake engine sound in Mercedes A-Class
Mercedes-Benz has been accused of using fake engine sounds in some of its models, including the A-Class. The accusation is that the car manufacturer artificially enhances the engine sound through the car's speakers to make it seem louder or more powerful than it actually is. This feature is known as "Active Sound Design" or "Progressive Sport Sound" in the new E-Class.
In the A-Class, specifically the A35 and A45 models, there is a system called AMG Real Performance Sound Option. This system amplifies the exhaust pulsations into the cabin via a DSP Amplifier. The A35 does not have a sensor for exhaust pulsations and relies solely on the DSP map for the sound. Both the A35 and A45 have an exhaust flap valve that actuates depending on the selected mode.
Some customers have expressed concerns about the fake engine sound in their Mercedes A-Class vehicles. They have reported that the car sounds much louder in reviews and promotional materials than it does in reality. One customer even paid $550 for the fake engine sound in their C43 model, only to be disappointed by the lack of actual exhaust sound.
It is worth noting that not all Mercedes A-Class models have this feature. The A200, for example, does not have the AMG Real Performance Sound Option. Additionally, some customers have found ways to disable the fake engine sound by customizing their driving modes or seeking assistance from dealers or mechanics.
While some people appreciate the enhanced sound, others have expressed a desire for transparency and the option to disable the fake engine sound if they prefer a more authentic driving experience. The mixed reactions to this feature highlight the importance of providing customers with clear information and customization options to suit their preferences.

AMG models with fake engine sounds
Mercedes-AMG, the tuning branch of Mercedes-Benz, has been criticised for its use of fake engine sounds in some of its models. This feature, known as "Active Sound Design", involves pumping fake engine noise through the speakers to enhance the driving experience. While some customers appreciate the option of a more powerful-sounding engine, others have expressed disappointment and frustration.
The AMG models with fake engine sounds include the CLA 35, C43, AMG GT63, and the upcoming AMG GT XX. The CLA 35, a sporty model, activates the fake engine noises in Sport+ mode, while the C43 offers it as a $550 add-on. The AMG GT63, a high-performance car, also features this function, which can be turned on and off via the MBUX system. The AMG GT XX, a Porsche Taycan-fighting electric sports sedan, takes this a step further by including simulated gear shifts and vibrations to mimic the sensory experience of driving a V-8-powered AMG.
In addition to these models, there are also reports of fake engine sounds in the Mercedes-Benz A-Class and GLA-Class. Some owners of the A-Class have noticed a "fake exhaust noise" in the cabin, created by amplifying the exhaust pulsations into the cabin via a DSP amplifier. Similarly, GLA-Class owners have questioned whether their vehicles produce authentic engine sounds, with some believing that the impressive roar of the M270 power plant is enhanced through the speakers.
While some AMG models do have fake engine sounds, it's important to note that not all Mercedes-AMG vehicles employ this feature. The AMG engineers' goal is to evoke emotion and provide a sensory experience that meets customers' expectations. However, they also prioritise authenticity when it comes to power, drivability, and track performance.

Fake engine sound in the EQS Electric Sedan
Electric vehicles (EVs) differ significantly from combustion engines in terms of driving dynamics and the changes in the gearbox. Therefore, the sound of an engine is challenging to recreate convincingly, as evidenced by video games. Mercedes-Benz initially considered giving the EQS Electric Sedan a fake engine sound but decided against it for several reasons. Firstly, they recognized that customers who choose to buy an electric vehicle are interested in a unique 'user experience' and seek acoustic differentiation. These customers are keen on embracing new transportation methods and specifically want a distinct sound from EVs rather than a simulated engine noise.
Moreover, the trademark AMG experience is associated with combustion engines, and offering a fake engine sound in an EV could fall short of customer expectations. Mercedes-Benz also pointed out the challenge of recreating engine sounds authentically, as simply inducing or enhancing engine and exhaust sounds through speakers would not satisfy buyers. Instead, the EQS Electric Sedan offers three "soundscapes" to choose from: Silver Waves, Vivid Flux, and Roaring Pulse. These digitally produced noises are meant to fill the absence of internal combustion engine sounds without directly mimicking them.
While some people find the idea of fake engine sounds amusing or enjoyable, others believe it would become annoying or lose its novelty over time. Additionally, there are concerns about the effectiveness of sound dampening in EVs, which can affect the overall sound experience. Mercedes-Benz's decision to forgo fake engine sounds in the EQS Electric Sedan aligns with the understanding that EV buyers are looking for an acoustic experience that sets their vehicles apart from traditional combustion engines.
It is worth noting that Mercedes-Benz has experimented with fake engine sounds in other models, such as the AMG GT63, where they offer an "Active Sound Design" option. However, some Mercedes-Benz models like the A-Class and GLA-Class have sparked discussions about the presence of fake exhaust noises in the cabin, with owners exploring ways to turn down or disable these sounds. Overall, the EQS Electric Sedan stands as a testament to Mercedes-Benz's commitment to providing a unique and authentic acoustic experience for its EV customers.

Fake engine sound in the GLA 250
The Mercedes-Benz GLA 250 is a powerful car with a pleasant roar from its M270 power plant when accelerated briskly. Some car enthusiasts have questioned whether the impressive sound of the GLA 250's engine is enhanced or artificially induced, especially given that the lower part of the engine is not fully encapsulated and the hood lacks insulation.
While some car manufacturers have been known to use fake engine sounds to enhance the driving experience, it is unclear whether Mercedes-Benz employs this tactic in the GLA 250. One source mentions the presence of an "engine sound module" in the GLA Audio wiring diagrams, but it is uncertain if this module exists or what its function might be.
In contrast, a GLA 250 owner on a Mercedes-Benz forum stated their belief that the impressive sound of their car's engine was not artificially induced through speakers, as they noticed that the lower part of the engine was not fully encapsulated and the hood lacked insulation, which could be for increasing engine sound or ventilation.
Mercedes-Benz does employ fake engine sounds in some of its AMG models, where a sensor in the exhaust system takes pulsations, feeds the signal to a DSP amplifier, and then generates engine/exhaust sounds that are fed into the speakers. This feature can be disabled by a dealer or mechanic with a Mercedes star scan tool.
While there is no confirmation that the GLA 250 uses fake engine sounds, it is possible that Mercedes-Benz employs similar technology in this model, contributing to the impressive sound that owners have noted.

Fake engine sound in the CLA 35
Mercedes-Benz has been accused of using fake engine sounds in some of its models, and the CLA 35 is one of the cars that has come under scrutiny. While there is no definitive evidence, some owners and enthusiasts have shared their experiences and observations about the vehicle's engine sound.
In online forums and discussions, CLA 35 owners have reported hearing a "weird" or "fake" sound coming from the engine. Some have speculated that the sound is artificially enhanced or synthesized, similar to the accusations made against other Mercedes models. However, it's important to note that these claims have not been officially confirmed by Mercedes-Benz.
The CLA 35's engine sound has been a topic of discussion among car enthusiasts, with some believing that the sound is artificially generated and pumped through the speakers. One common observation is that the fake engine sound seems to be linked to specific drive modes. For example, some owners have noticed that the fake engine noise only activates in Sport+ mode, and by customizing their Individual mode, they can avoid the artificial sound. This suggests that the sound may be tied to certain performance settings or parameters.
Some CLA 35 owners have expressed dissatisfaction with the fake engine sound and have explored ways to disable or reduce it. One owner shared their experience of having the fake noise coded out, resulting in a quieter driving experience. Others have attempted to locate the sensor in the exhaust system or explored options within the dealer menu to minimize the effect. However, the process of disabling or reducing the fake engine sound in the CLA 35 is not straightforward, and some owners are still seeking solutions.
While the CLA 35's engine sound has sparked debates about its authenticity, it's worth noting that Mercedes-Benz has not publicly acknowledged the use of fake engine sounds in this model. The company has, however, introduced features like "Active Sound Design" in other models, which suggests a deliberate enhancement of the auditory driving experience. Whether the CLA 35's engine sound is entirely natural or augmented remains a subject of discussion among owners and enthusiasts alike.
