No matter how the automobile market changes, family cars have always been one of the areas with the most intense competition among brands and the most popular among consumers. When talking about family cars, comfort is an important issue that cannot be avoided. So what is comfort? Of course it’s not just as simple as “sitting comfortably”. This time we chose the Pentium B70 and the Volkswagen Lavida, two models that have attracted much attention. They are also priced at 120,000 to 30,000 yuan. They have also gone through more than ten years of iteration history. Between independent and joint venture models, we will dismantle the models and analyze them from multiple angles to discuss who is a comfortable and competent "national family sedan".
Real car dismantling The performance of the Pentium B70 is surprising
When people consider the comfort of a car, most people will pay attention to the performance of the seats, so we will go straight to the point and start with the wrapping and support of the seats for comparison.
Seat disassembly

Spring area comparison (on the left is the Pentium B70)
Judging from the results of seat disassembly and cutting, the seat materials of the Pentium B70 and Volkswagen Lavida are both wrapped in leather, and there is no obvious difference in touch. The internal materials are all sponge plus foam filler, but there are certain differences in the thickness of the seat cushion and the design of the spring area. The spring area of the B70 is slightly larger, and the thickness of the main driver's seat cushion in key support positions such as thighs and buttocks is also larger, so the support will be better. Specific to the data, according to the cushion-type elastic pressure distribution system, the maximum pressure value of the Pentium B70 rear seat is 271mmHg, and the Lavida is 313mmHg. Under normal circumstances, the smaller the pressure on the seat, the larger the riding contact area and the more comfortable the body feeling.

At the same time, a large area of metal plate is added to the back of the rear seat of the B70, which can reduce the impact of luggage in the trunk to a certain extent when an accident occurs. Lavida is equipped with front seat lumbar support adjustment. Perhaps during the actual ride, the difference in experience between the two cars will not be particularly obvious, but when traveling long distances or driving over speed bumps, the thickness and rebound ability of the B70 seats should be more in line with Chinese consumers' requirements for comfort and isolation.
Dynamic/Static Measurement of In-car Noise Value
In addition to seat comfort, quietness and comfort are also an important criterion for presenting a sense of class. It is also an aspect that is often ignored by this level of consumer groups, and the conclusions drawn from different reference systems are also different. Therefore, regarding the efforts made by the B70 and Lavida in quietness, we chose to use the NVH measurement data as a rational criterion for evaluation.
field NVH test results show that when the Pentium B70 is driving dynamically at a speed of 60km/h, the maximum noise inside the car within 1 minute is 66.4dB. When it is parked statically on the side of the urban road with the windows closed, the noise inside the car when a car passes by is 53.4dB. Under the same test conditions, the data on the Volkswagen Lavida are 69.3dB and 59.7dB respectively. It can be seen that the B70 car is quieter no matter dynamic or static.
The Pentium B70 is equipped with sound-absorbing cotton material in many parts of the body.
The excellent quietness of the Pentium B70 is due to the solid materials used in the body hardware, which strengthens the vehicle's ability to suppress noise. By dismantling the vehicle, we found that the B70 has sound-absorbing materials in many parts of the body, including a very large amount of sound-absorbing cotton, including the upper and lower guards of the A/B/C pillars, the instrument panel, the glove box, air-conditioning ducts, the trunk guard, the firewall, The front/rear wheel arches and other positions are wrapped with sound-absorbing cotton. The sound-absorbing cotton covering area of the four door panels reaches about 40%. A thick layer of PUR foam material is used under the chassis carpet. A sound-absorbing cotton area of about 0.27 square meters is also arranged behind the roof. At the same time, the B70 has a comprehensive chassis armor , which can also play a certain degree of sound absorption.

The sound-absorbing cotton of the Lavida is mainly located on the hood, the upper guard plate of the C-pillar, inside the instrument panel, the firewall, the partition above the trunk and the rear seat. There is no sound-absorbing cotton on the door panels, and most of the chassis materials are plastic boards . In terms of anti-vibration plates, the B70 has a larger area and a larger number of Lavidas.In fact, the sound insulation effect of the Lavida and the use of sound-absorbing cotton are not bad, and it is no problem for daily household use. However, relatively speaking, the Pentium B70 is more willing to use materials and has higher attainments in quietness and comfort.

Overall, the Pentium B70 and the Volkswagen Lavida are both 100,000-class high-quality family sedans that can withstand disassembly. As an independent product, the B70 has solid performance at the hardware level. What is even more surprising is that at the same price or even with a lower threshold, its seats and quiet comfort are not inferior to joint venture models. Therefore, in the China Automotive Center vehicle comfort cockpit certification, it is not surprising that the B70 won two certifications: "Seat Comfort Star" and "Quiet Star".
Vehicle Comfort Cockpit (6A) Certification Bestune B70 deserves its name
In fact, the vehicle comfort cabin certification of the China Automotive Center mentioned above not only covers seat comfort and quiet comfort, but also involves four certifications: CN95 healthy cockpit, thermal comfort, space comfort, and driving comfort. The Bestune B70 has passed difficult tests and strict audits, and has performed well in six major comfort items. It is the first sedan product to win the honor of vehicle comfort cabin (6A) certification.
For example, in terms of space, the Pentium B70 has a wheelbase of 2800mm and a length of 4810mm. The interior space of the Pentium B70 is comparable to that of the B-class car . The head is not depressed, the legs are very spacious, and the whole car has a total of 25 storage spaces. The rear seats support flat folding. The ample and flexible space performance makes it a good partner for family travel.
For example, in terms of air conditioning, the B70's air conditioning thermal comfort system can quickly adjust heating and cooling according to the set temperature, and through four zones of independent adjustment, there will be no obvious temperature difference between the front and rear rows. Remotely turning on the automatic air conditioning via the mobile phone APP is also a very smart and convenient function. No matter whether it is hot or cold, you can adjust the temperature in the car to a suitable and comfortable temperature before entering the car.
For example, in terms of health, the super filter element equipped with B70 integrates five core technologies and an eight-layer filtration structure. It can not only block harmful gases such as formaldehyde, TVOC, PM2.5, but also has antibacterial performance and 70° high temperature sterilization function to ensure the cleanliness and health of the interior space in the car.
At the same time, we also discovered some user-friendly and comfortable details of the B70. In order to make it easier to get in and out of the car, the B70's rear door opening is wider, and the front and rear ends of the B-pillar lower guard are concave. The driver's seat will automatically move backward after the engine is turned off. The door guard and the inclined handle are covered with water-based soft materials, which are environmentally friendly and comfortable to the touch. The starry sky dot matrix ambient lights made by laser engraving are also a bonus to improve comfort.
written at the end
There is an inevitable reason why the Pentium B70 has become the "new national sedan". It brings a luxurious experience that exceeds the original price in terms of comfort, which is unmatched by some joint venture models of the same level. If you care about the ride experience in the car and agree with the importance of comfort in the composition of the family sedan experience, then the Pentium B70 is one of the models worth considering.
allows the most ordinary and largest Chinese consumer group to achieve a new level of car experience and a fulfilling and valuable life. FAW Besturn has always been working hard in this direction. We are happy and proud that the national brand represented by FAW Besturn continues to advance, and we look forward to witnessing more independent car companies achieve breakthroughs and leadership.
