The "MBUX" is Causing a Stir

The Mercedes-Benz A-Class has undergone a full model change, marking its fourth generation. While its style is that of a conventional hatchback, the car itself has evolved significantly.

The international press drive for the new Mercedes-Benz A-Class was held in April 2018 around Split, Croatia. This model has been a major topic of conversation since its public debut at the Geneva Motor Show.

The most significant highlight is "MBUX," the latest infotainment system, "Mercedes-Benz User Experience." Of course, the car's overall refinement has also greatly improved. First and foremost, the driving enjoyment of the new A-Class deserves special mention.

We had the opportunity to drive two models in Croatia: the "A 200" equipped with a newly developed 1,332cc engine, and the powerful 1,991cc "A 250."

Both models share a 7-speed dual-clutch transmission and front-wheel drive. However, a manual transmission is also available for the A200 in its home market, and 4MATIC all-wheel drive will be added to the lineup later.

The A200's 1.33-liter (as Mercedes-Benz writes it) unit produces a maximum output of 120 kW (163 hp) at 5,500 rpm and a maximum torque of 250 Nm at 1,620 rpm. It replaces the current A180's 1,595cc unit, surpassing it in both output (90 kW/122 hp) and torque (200 Nm).

Improved fuel efficiency is also a feature of this engine. For the first time in a Mercedes-Benz four-cylinder, it employs a system where two cylinders deactivate under low load.

The newly designed chassis has been reinforced for increased rigidity, and lightweight materials are used throughout the body, making it about 20 kg lighter than the current model, depending on the specific configuration. Furthermore, noise reduction has been enhanced through effective use of sound insulation materials. Developers we met at the press event emphasized that a complete re-evaluation of the overall quality from the ground up is a key feature of the new A-Class.

Impressed by Handling Reminiscent of the C-Class

The developers' words rang true the moment I started driving on the road. The A 200 offers ample power from low revs and accelerates smoothly without any hesitation. The ride comfort is excellent, with bumps and uneven surfaces absorbed gracefully, even on poor roads. It provides a stable and comfortable ride at high speeds. And it's simply enjoyable to drive.

What impressed me most was the handling, including the steering feel. It possesses a level of refinement clearly distinct from previous front-wheel-drive Mercedes-Benz models. The unique weighting when turning the steering wheel and the car's response to steering input are reminiscent of rear-wheel-drive models like the C-Class.

I believe that what has traditionally made Mercedes-Benz cars so special is their unique steering feel, which seems to engage in a dialogue with the driver. It's not that the response is poor, but rather that it doesn't solely pursue outright speed like a sports car. The magic lies in the interplay between the steering speed and the chassis's reaction speed, including the suspension. The way it corners, including the roll characteristics, conveys a sense of substance.

The new A-Class offers a driving experience that will impress even those who have long cherished Mercedes-Benz cars.

The A250's 2-liter engine produces a maximum output of 165 kW (224 hp) at 5,500 rpm and a maximum torque of 350 Nm at 1,800 rpm. The model I test drove was equipped with the AMG Line, featuring 19-inch Pirelli P Zero tires with a 40% aspect ratio, and a striking front bumper design.

My first impression was one of power. The ride, however, was firm. With a relatively compact body measuring 4.4 meters in length and a substantial 350 Nm of torque, the car responds instantly to accelerator input. Plenty of power is available from around 1,500 rpm, and the torque pulls the car forward relentlessly.

Both cars are equipped with the "DYNAMIC SELECT" drive mode selector, allowing for choices like Comfort, Eco, and Sport. Sport mode is, as is typical for Mercedes-Benz, particularly enjoyable. The A250, with its slightly heavier steering and firmer suspension, truly allows you to experience its inherent appeal in Sport mode.

The seat bolstering is excellent, and comfort is high, enhanced by features like the climate control system with large, turbine-shaped air vents, which Mercedes-Benz describes as being "inherited from the S-Class." The wheelbase has been extended by 30 mm to 2,729 mm compared to the current model. The overall length is 4,419 mm (+120 mm), width is 1,796 mm (+16 mm), and height is 1,440 mm (+6 mm).

Scheduled for Introduction in Japan within 2018

Another notable feature of the new A-Class, mentioned at the beginning, is MBUX (Mercedes-Benz User Experience). The optional configuration includes a dual-monitor setup with two 10.25-inch screens, allowing for vehicle settings and infotainment control. Scrolling icons vertically accesses deeper setting layers, indicating the wide range of adjustable functions.

Another aspect is its seamless integration with smart devices. Through an application called "Mercedes me," users' smart device functionalities are significantly expanded.

"Digital Access Key" is a feature that allows a smart device to be used as a key. Registered users with a compatible smart device can access and drive the car. This enables car sharing.

Furthermore, the third key feature is the voice control function. Saying "Hey, Mercedes" prompts the car to respond with "How may I help you?" much like Apple's Siri. Many functions, including climate control, navigation destination input, phone calls, and opening/closing the seat heaters or glass roof blinds, can be operated by voice.

While there are instances where the voice recognition response is slow, the development team states, "The learning function means that its performance should improve with continued use." The test vehicles in Croatia only supported English and German, but the system is designed to work in local languages worldwide. Development for the Japanese market is currently underway.

Mercedes-Benz Japan aims for an introduction of the new A-Class within 2018, if possible.
