The two models differ in powertrain, exterior design, dimensions, and safety configurations: 1. In terms of size, the GLA is smaller than the GLB, with the GLB offering more space and even a seven-seat version as an option. 2. Regarding the drivetrain, all Mercedes-Benz GLB models are front-wheel drive, while the Mercedes-Benz GLA, at the 300,000 RMB level, features an on-demand all-wheel-drive system. Models with all-wheel drive are clearly more advanced and come with higher manufacturing costs. 3. In terms of specific configurations, the Mercedes-Benz GLA is equipped with knee airbags, whereas the Mercedes-Benz GLB is not. This might be because the GLA was originally introduced to China as an imported vehicle, and the knee airbag safety feature was not removed during the localization process. 4. In terms of power, the Mercedes-Benz GLB is equipped with a 1.3T turbocharged engine, delivering a maximum power of 100kW (136PS) and a maximum torque of 200N·m, paired with a 7-speed dual-clutch transmission. On the other hand, the Mercedes-Benz GLA is equipped with 1.6T and 2.0T turbocharged engines.

I've always been interested in Mercedes-Benz SUVs and often research car information. Both the Mercedes-Benz GLA and GLB are compact models, but the main differences lie in space and practicality. The GLB is larger in size with a higher roofline and offers an optional third-row seat, making it particularly suitable for family users like me with children, as it can easily accommodate strollers and luggage for the whole family. The GLA is much more compact with a sleek and attractive design, but its trunk space is limited, suitable only for daily use by two people. Additionally, the GLB has higher ground clearance and better light off-road capability, while the GLA is more flexible and fuel-efficient for city commuting. Maintenance costs are roughly the same, and Mercedes-Benz's quality is reliable—choosing between them depends on lifestyle needs. If you love adventurous trips, the GLB is the smarter choice.

What does AMT mean in cars?

The full name of AMT in cars is Automated Manual Transmission, also known as Sequential Transmission. It is an improved version based on traditional manual gear transmissions, combining the advantages of both AT and MT into an integrated electro-hydraulic automatic transmission. Specifically, it uses a manual transmission as the base and automates the operation of components originally controlled by human force, such as clutch disengagement and gear shift forks. The working principle of AMT is: determining the optimal gear, controlling the clutch disengagement and engagement, the gear lever's shifting, and the synchronous adjustment of the engine throttle opening, which were originally done manually by the driver, ultimately achieving automated control of the shifting process.

How to Parallel Park Without Lines?

First, align your car parallel to the car in front. Then shift into reverse and quickly turn the steering wheel all the way to the right. When at a 45-degree angle to the parking space, quickly straighten the wheel. Continue reversing until your right rearview mirror covers the left taillight of the car in front. Keep reversing while making slight adjustments to your car's position. Stop when you're about 1.5 meters from the parking space, adjusting until your rearview mirror aligns with the marking line of the second parking space ahead. Turn the steering wheel fully toward the parking space. Once your car is parallel to the space, straighten the wheel.

How to Clean Up Water in the Back Seat of a Car?

If a small amount of water enters the car, it won't cause significant damage. Simply open the car windows on a sunny day to allow thorough airing and drying. The main repair process involves removing the accumulated water inside the car. There are several rubber seals located at the bottom of the vehicle chassis. Opening these seals will allow the accumulated water inside the cabin to drain out. Remember to turn on the air conditioning and adjust the vehicle's circulation switch to internal circulation mode. This will help expel the water vapor from the cabin through the air conditioning system.

How to Adjust Car Headrests?

First, adjust the seat angle to keep your back as upright as possible, but note that the seatback angle should not be overly vertical. It's advisable to maintain a slight recline, and the headrest height should align with your head. The distance between the back of your head and the headrest should be as small as possible to maximize the cushioning effect on your head and neck, with a maximum spacing of no more than 4 centimeters. After adjusting the headrest height, ensure the pin lock is secure by fixing the headrest into the corresponding height slot.
