What are the new technologies of the BMW 325 and what is the difference between the BMW 320 and the

BMW, which is based on the market as a technology leader, inevitably brings several new technologies to consumers every time it launches a new car, and this practice has been implemented for many years, and we have also found 3 new and worthwhile technologies.

Technique 1: Brake disc drying function. When the wiper pre-rains are activated, the electronic components connected to the wiper will bring the brake shoes closer to the brake disc, thereby reducing the distance between the shoes and the brake disc, ensuring that the brake disc stays dry for a long time during rain.

In addition, if the accelerator is suddenly released while driving, the system will think that the driver needs emergency braking, and will automatically move the shoes closer to the brake disc in advance. The 3 Series in manual gear also brakes automatically when starting on a slope, and the system releases automatically when the accelerator is pressed.

Technology 2: Run-flat tires. All models in the new 3 Series sedan are equipped with run-flat tyres as standard, allowing them to travel up to 250 km at speeds of up to 80 km/h, even with a full puncture.

The application of run-flat tires greatly improves the safety of driving, and at the same time eliminates the need for spare tires, reduces the weight of the vehicle, and provides more luggage space. In the event of an emergency, installing a run-flat tire can extend the mileage after a puncture to reach the repair station for repairs. On the day of the test drive, we personally tested its efficacy, in the front and rear run-flat tires completely deflated, driving at a safe speed of 80 kilometers per hour, the previous discussion still maintains the due steering, the slight deviation trajectory let the driver clearly know, a slight correction of the direction is, the safety is relatively stable.

Technology 3: magnesium aluminum alloy material. For the first time, magnesium-aluminum alloy materials were used to manufacture the engine body, which is the first new material used by a global automaker in a production vehicle.

Due to the very light weight of magnesium, the weight of the engine body can be reduced if it is used, but the instability and mechanical bearing capacity of magnesium are not enough and are abandoned by various car manufacturers. Today, BMW's technical department has made the engine body 10 kg lighter than the all-aluminum engine in the world, making it the lightest six-cylinder engine in the same performance class in the world.

1. Price BAI grid: 325** is higher than 320, which belongs to the upgraded version of 320.

zhi2, displacement: 320 is the displacement, dao325 is the displacement.

3. Engine version: 320 is a 4-cylinder engine engine, and 325 is a six-cylinder engine. The 320 is an improved version of the old 318i engine of the previous generation E46, and the 325 is the ** magnesium-aluminum alloy engine of the E90.

4. Brake disc: 320 is the brake disc of the front 292 and the rear 296. The 325 is the brake disc for the front 300 and rear 300.

5. Wheels: 320 is 16 inches, 325 is 17 inches.

6. Tire size: 320 is 205mm, 325 is 225mm.

7. Interior: 320i is an ordinary steering wheel, 325i is a sports steering wheel. Except for the top configuration of the 320i, the rest of the speakers have shrunk, even the power amplifier is the same, and the 325i is all mid-level audio from Harman Becker.

8. Driving system: 320i is cruise control system, 325i is dynamic cruise control system. The 320i's DSC dynamic stabilization system is the same as that of the older 318i, while the 325i is a true next-generation DSC advanced dynamic stability system.

Hello, the displacement of the 325 is larger than that of the 320, the former is the latter. **Definitely 325 high, comfort type can't be considered.

**It must be that the 325 is expensive, and the comfort is about the same, but the configuration is slightly different. In addition, the biggest difference between the two is the displacement. One yes, one yes. If you don't consider ** and fuel consumption, it is recommended that the 325 is better!

I'll be blunt: 320 for women and 325 for men

That should be 325 is better, you can go to the 4S store to have a look and experience it.

If you don't understand bai, don't mislead people. BMW all du

Cars have i This zhi is not to distinguish between domestic and intake. There is also a version of the imported car.

There are two models, the 320i and 320d. i stands for gasoline engine. d stands for diesel engine. Domestic BMW only has i, that is, gasoline engine. BMW models with a D can be found everywhere in Europe. With D means that the car uses a diesel engine.

The difference lies in the power performance: the 320 is a 4-cylinder engine that is an improved version of the old 318i engine of the previous generation E46.

The 325 is a six-cylinder engine, which is the **DAO magnesium-aluminum alloy engine of the E90, and the BMW 325 has a stronger performance in power.

The BMW 3 Series is described as follows:

1.The BMW 3 Series is the BMW Group's new generation of sedans, and the BMW 3 Series once again sets a new standard for sedan in its class, with a new level of aesthetics, engineering, high-tech connotations, luxury comfort and safety.

2.The BMW 3 Series is powered by a 4-cylinder model that has gradually evolved into a complete series.

3.BMW's safety performance is top-notch, with its steel body made of high-strength steel, which is more than 50 percent stiffer than its predecessor, which ensures optimal protection of occupants and ensures that the doors can be opened freely in the event of a predetermined deformation and an accident.

4.In addition to the steel body and the eight airbags that are fitted as standard, the safety restraint system and the electronic control unit further improve passive safety.

5.The comprehensive electronic insurance system in the BMW 3 Series minimizes the risk of short circuits in the event of a major accident.

If you want to increase the power to a higher level, you can try the HDP program, which comes with functions such as starting the roaring pops tempering gun to reduce the oil temperature, and there are improvement data and ** on the official website, if you are interested, you can take a look!

Advantage 1: Handling, enough power.

Say that BMW's handling is good, I believe no one will refute it, right? Although some people say that this generation of BMW 3 Series has lost its handling, compared to similar models, the BMW 3 Series is still a sedan with excellent handling.

It is equipped with an engine, I chose the 325i m sports night package, the engine power is only 184 horsepower, and the power is not strong, but the power is enough for the noisy brigade, with the blessing of the 8-speed manual automatic transmission, the power output is direct and crisp, coupled with excellent handling, it is very cool to drive in the city.

Advantage 2: Large space and luxurious configuration.

The 325i m sports night package I chose, with a wheelbase of 2851mm, is completely enough for a mid-size sedan, for my height of 175cm, the space is completely sufficient, whether it is headroom or legroom, it is very spacious and practical, and there is no need to worry about BMW's space at all.

In terms of configuration, the BMW 3 Series also has a very classic sense of luxury, which is different from the luxury of Mercedes-Benz, BMW's luxury is touchable luxury, while the Mercedes-Benz interior reveals a rich luxury, and the style is completely different.

Advantage 3: The fuel consumption is very low, about 100 kilometers.

What I didn't expect the most was that the BMW 3 Series was so fuel-efficient, I think luxury cars are not fuel-efficient, and they need 10 fuels for 100 kilometers, right? But I drove 3560, daily urban and intercity highway running, and the fuel consumption was as low as about 100 kilometers, which completely surprised me. Frankly, very satisfied with such fuel consumption.

Disadvantage 1: The smell in the car is relatively heavy.

More than 300,000 luxury cars, the BMW 3 Series is not cheap, but the lack of preparation means that it has no shortcomings. First of all, the smell in the car is relatively strong, which is not only my personal feeling, but my friend also thinks that the smell of the new car in the car is relatively raw. At present, I have traveled more than 3,500 kilometers, and I don't know how to deal with this problem, and it seems that buying a charcoal bag has no effect.

Disadvantage 2: The car machine is not easy to use, and there is an abnormal noise in the car.

The car machine system of the BMW 3 series is not easy to use, the mobile phone does not support the same screen of the Android mobile phone, and the screen is not resistant to dirt, and it must be taken care of often in daily use, otherwise it is easy to see the problem when it is reflected. Another disadvantage is that the car has some abnormal noises, although it will not affect the use, but it always feels like a luxury car of more than 300,000, this problem should not be.

Disadvantage 3: The brakes nod seriously, which is weird, and the BMW 3 Series brakes nod badly, is this a big problem? It is undeniable that the BMW 3 Series is easy to drive, but in the case of sudden braking, the nod of the whole vehicle is more serious, and the experience is not good.

Therefore, it is recommended that you drive every day, or drive gently.

As a mid-to-high-end sedan, the BMW 325 has many advantages. First of all, it uses the advanced turbocharged engine of Zhaoshi, coupled with the high-tech engine management system, with excellent power output. Secondly, the body design is stylish, the configuration is luxurious, the driving is comfortable, especially its safety performance is good.

However, the BMW 325 also has some shortcomings: the maintenance cost is higher than that of ordinary cars, which is not suitable for people-friendly consumers; The interior space is relatively narrow, and it is not very comfortable to ride for a long time. Overall, the BMW 325 is outstanding in the high-end car market, but consumers need to consider it comprehensively according to their actual needs before purchasing.
