Is the Mercedes-Benz GLA200 very noisy?

The Mercedes-Benz GLA200 is not very noisy. As a high-performance coupe, the GLA200 has minimal noise compared to other vehicles in the same category and price range. The main sources of noise in the Mercedes-Benz GLA include engine radiation noise, tire rolling noise, intake and exhaust noise, and drivetrain noise. Currently, the most commonly used noise reduction technology is passive isolation, with damping, sound-absorbing materials, and structures being widely applied in automotive noise control. More details about the Mercedes-Benz GLA are as follows: 1. Overview: The Mercedes-Benz GLA is positioned as a compact SUV. In terms of dimensions, it measures 444918041535mm with a wheelbase of 2699mm. 2. Powertrain: It is equipped with a 1.6T inline 4-cylinder turbocharged engine paired with a 7-speed dual-clutch transmission, delivering a maximum power of 115KW, maximum horsepower of 156PS, and maximum torque of 250N·m, with front-wheel drive. It also offers a 2.0T inline 4-cylinder turbocharged engine (low-power version) paired with a 7-speed dual-clutch transmission, producing a maximum power of 135KW, maximum horsepower of 184PS, and maximum torque of 300N·m, with an all-wheel-drive system. The high-power version of the 2.0T inline 4-cylinder turbocharged engine, paired with a 7-speed dual-clutch transmission, delivers a maximum power of 155KW, maximum horsepower of 184PS, and maximum torque of 350N·m, also with an all-wheel-drive system. 3. Safety Features: In addition to basic features (such as ABS, EBD, etc.), the GLA comes standard with ESP, front and side airbags, side curtain airbags, knee airbags, and tire pressure monitoring, providing comprehensive protection for passengers.

The noise control performance of the Mercedes-Benz GLA200 needs to be discussed case by case. Having driven this car for a while, I can say that at low speeds in the city, the noise is minimal, especially in traffic jams where the engine sound is almost inaudible. However, on the highway, wind noise does become noticeable, particularly when the speed exceeds 100km/h, with a whooshing sound coming from the area around the side mirrors. Additionally, tire noise depends on the road surface—it's acceptable on newly paved asphalt but becomes quite pronounced on older concrete roads. The engine sound is slightly louder during rapid acceleration, but it's more of a crisp, sporty roar. Overall, as a compact SUV, its performance is decent, slightly noisier than sedans in the same price range, but it doesn’t affect daily use at all.

From an engineering perspective, the noise in the GLA200 originates from several aspects. The engine compartment sound insulation is well-executed, with minimal perception at idle. High-speed noise primarily stems from aerodynamics, particularly wind shear sounds generated by the A-pillar design. The chassis sound insulation layer is approximately 15mm thick, less than premium models, resulting in noticeable tire noise transmission. While the exhaust system features optimized muffler design, vibration noise still transmits during hard acceleration. Owners are advised to opt for quiet tires, which significantly enhance cabin tranquility. Regularly inspecting door seal conditions can also reduce wind noise—a detail often overlooked by long-term owners.

Compared to its peers, the Audi Q3 and BMW X1, the noise control of the GLA200 is indeed slightly weaker. Last week, I helped a friend test these three cars, and at a steady 80km/h cruise, the cabin decibel level of the GLA was about 3dB higher. The road noise transmitted from the chassis is more noticeable, and the engine sound above 3000 rpm also has a distinct granularity. However, the cabin sealing is good, with environmental noise isolation better than Japanese cars when the windows are closed. If you have high requirements for quietness, the active noise cancellation feature in the top trim is very practical. It cancels out specific frequency band noises through reverse sound waves, which is particularly comfortable during long-distance driving.
