B-class car is what we usually call a medium-sized car. Its positioning characteristics are mainly reflected in two aspects. 1. The engine displacement is above1.8L. Of course, there are also 1.5T engines used by mercedes benz c and Accord, but the power parameters are no less than 2.0L engines. Second, the wheelbase is more than 2,800 mm. With the continuous improvement of vehicle size requirements, the wheelbase of Cadillac CT5 and Audi A4L has exceeded 2,900 mm. Let me share several B-class cars with different price points. Let's see which car can win your heart more through power and sound insulation comfort.

About1:200,000-Volkswagen Magotan -2020? 380TSI? DSG? luxurious

Although Magotan is still not as good as Passat in market sales. However, in the testing process of China Insurance Research Institute, Magotan performed better than Passat.

dynamic characteristics

As the main power vehicle of Magotan, the 380TSI is equipped with the EA888-DKX high-power version of 2.0T direct injection engine, with the maximum power 162kw and the maximum torque of 350N.m We are not unfamiliar with this engine, and we can also see it on Volkswagen Touran, Tiguan L, Audi Q3 and Passat. At the same time, the third generation EA888 engine optimized the oil-gas separator and added the piston sealing ring, which effectively improved the oil burning and abnormal noise.

The traditional Otto cycle used by DKX is not as fuel-efficient as Japanese VVT at low speed, but the engine will continue to be full of power at high speed, and the acceleration of 100 kilometers takes only 7.2 seconds. The throttle response is sensitive and there is no feeling of sloppiness.

Quiet comfort

In terms of comfort, I feel that Magotan is superior to Honda Accord in noise control in the same level interval. Although not as quiet and comfortable as Teana, I have the courage to compare with Camry. One is the heavy feeling of the German car itself, and the other is that the initial positioning of Magotan is a bit commercialized, so it is more inclined to be quiet and comfortable in the adjustment of the chassis and the choice of tires. Normal communication between the front and rear rows at high speed is not a problem, and there is no unnecessary noise and abnormal sound in the B-class car. The sound insulation effect is worthy of recognition.

disadvantage?

The disadvantage is that the maintenance cost of this car is relatively high, and the fuel consumption is worse than that of 330TSI when drinking 95 # gasoline and synthetic engine oil. More suitable for people who often need long-distance driving, full of power and fast speed.

About 2: 250,000-FAW Toyota Asian Dragon -20 19? Twin engines? XLE outstanding edition

The fifth generation of Asian Dragon was born under the framework of Toyota TNGA. The brand-new platform and dual-engine power system have all conveyed a message to us that it is getting closer and closer to lexus es.

dynamic characteristics

This model is equipped with a 2.5L naturally aspirated engine and a permanent magnet synchronous motor. The maximum power of the engine is 13 1KW, and the maximum torque is 221n.m. In terms of parameters, this engine has no outstanding power performance, but its peak torque speed range is wider than that of the pure fuel version of the 2.5L model, and the minimum torque output can reach 221n at 3600 rpm.

Sound insulation comfort

Because the Asian Dragon is a model with comfortable wind route built by Toyota's rigorous technology, it has made great efforts in riding space and sound insulation inside the car. The noise in the car idling to 120Km/h is only about 20 decibels. When the vehicle is driving below 60 mph, the motor is driving, so the noise is subtle, while when driving at high speed, the engine noise is not obvious and the tire noise will increase.

disadvantage?

The acceleration of 8.4 seconds per 100 kilometers is not very good in the same level, and it is slightly inferior to the Accord hybrid, mainly because the dynamic performance tends to be flat in the middle and late stages, but if it is used as a means of transportation to shuttle between cities, it is enough to cope with conventional road conditions. As a B-class car, I still like the average fuel consumption of 5 liters, which is more suitable for urban traffic and commuting.

Around 3: 300,000-BMW 3 Series -2020? Change money? 325Li? first edition

Speaking of BMW, you will think of power and control, plus the kidney-shaped design of the front air intake grille, blackened taillights, carbon-gray wheels and so on. It is emphasized that this is a sports car, without too many complicated designs, but it exudes an energy that can be "wild" at any time.

dynamic characteristics

The first edition of 325Li is equipped with a 2.0T turbocharged engine, with the maximum power 135KW and the maximum torque of 300N.m The mechanical combination of 8-speed automatic manual transmission and rear drive also makes the BMW 3 Series very high in power and handling. If the sport mode and S gear are turned on, its response will be faster, but there will be some attenuation in the later stage, which is why it is a few tenths of a second worse than CT5. In addition, the venue of this car is also very compact, and the body of the lane change is stable enough when driving at high speed. I don't know how to give oil, so I changed the front car to the rear car.

Sound insulation comfort

Some people say that the 3 series is no longer pure, but more and more inclined to home, and the control is lower than before. It is precisely because of this that the 3 Series has made great efforts in comfort since then, and the body has been lengthened and the suspension has been adjusted, and it has begun to "please" the passengers' feelings. Within 100Km/h, its vibration filtering feedback and noise control are still excellent, but when cornering and accelerating again, the noise will increase, but it is still within an acceptable range, which is not much different from that of the same class.

disadvantage?

Considering the market psychology, the size of BMW 3 Series is close to that of BMW 5 Series, and losing its compact body will weaken some driving pleasure. But because of this, it has more attributes and adapts to a wider range of people. In addition, a small number of feedback new 3 series low-speed gear shifting will have a sense of frustration, I hope this probability problem will not be encountered.

For the above three B-class cars, the power performance has its own advantages. Magotan is like a thrifty person, not much better than anyone, but not afraid to compete with anyone; Asian dragon is like a warm man of literature and art, who knows and can provide what you need, but knows a lot but is unwilling to make public; The BMW 3 Series is like a fitness instructor in loose clothes. You don't know this guy's strength until you touch him.

Which of the above three do you prefer? What's a good recommendation? Welcome to leave a comment at the bottom!
