In the articles that the professor pushes every day, there will be many readers and friends who ask various questions in the message area.
Professors will mostly answer these questions in time in the message area after seeing them, but due to factors such as the number of words, they cannot always speak in great detail.
Therefore, in order to better answer everyone's questions and provide a better platform for everyone to ask questions, the professor decided to open a column of "Although Asking And Professor Answering"!
Starting from this issue of the program, you can write your own questions about car purchase, car selection, car technology, car culture, car knowledge and other aspects in the message area below the program, and the professor will collect and sort out a batch of selected questions every week for detailed answers!
As the first program of "Although Asking the Professor's Answer", the professor selected some more representative questions to answer in the articles pushed in previous issues.

Which is better for Qijun, CR-V and RAV4 home? Which model is the most affordable?
First of all, the first question concerns all three models of compact SUVs, and involves a very important keyword - home.
Then when it comes to the choice of family models, the space factor becomes very important.
Among these three models, only Nissan X-Trail provides a 7-seat version of the model, if there are more people at home, then X-Trail is obviously a more suitable choice, a two-wheel drive 7-seat luxury version can meet most of the needs of use.
Even if the third row of X-Trail's carriage was really crowded last night, with it, it can still provide two more seats and two more family members if necessary; whether it is comfortable or uncomfortable, it can at least come in handy, which is its advantage.
For those friends who do not have many family members and do not have special needs in terms of multi-person travel, the Honda CR-V and Toyota RAV4 Rongfang are very good choices.
For these two models, the professor believes that the hybrid version is more worthy of recommendation.
After all, for family cars, the reduction of fuel consumption will significantly reduce the cost of the car, and Honda and Toyota's respective gasoline-electric hybrid technologies can achieve quite excellent fuel saving effect.
Among the two models, the Honda CR-V recommends the sharp and hybrid two-wheel drive net speed version, which increases the important passive safety configuration of the side curtain compared with the lowest model, which is more secure for family cars.
As for the Toyota RAV4 Rongfang, the choice of dual-engine two-wheel drive elite version can meet most of the use needs, and the key safety configuration has not been reduced because it is a hybrid minimum.
As for which of these two models is good, the professor still recommends taking the family to the store to see the car and test drive the experience together, after all, the family car, the family's feelings are more important!
How about 400,000 to buy Pajero?
The second question concerns the model is more special, for fans and off-road enthusiasts, Mitsubishi Pajero has a high status, is a fairly classic hardcore off-road vehicle.
However, at present, Mitsubishi Pajero has stopped production, and there is no new model on the market, so it can only focus on the second-hand market.
The budget of 400,000 yuan can now easily buy a 2019 Model Pajero 3.8L Middle East version, and the version officially introduced in China can of course also be bought, but only a 3.0L engine, and the power is weaker.
But from the product level alone, spending 400,000 yuan on Pajero is not an affordable option.
After all, the 3.8-liter 6G75 V6 engine can only output 247 horsepower and 329 Nm peak torque, the gearbox is relatively old, coupled with the outdated interior design and simple interior configuration, Mitsubishi Pajero's car experience is not up to date.
Therefore, 400,000 to buy Mitsubishi Pajero can only pay for "feelings", and if you really need a good hardcore off-road vehicle, then the professor feels that you can consider the Ford road shaker.
Buy a low-end version for more than 200,000 yuan, use the saved budget to upgrade the chassis, transmission system, tires, intake and exhaust, etc., so that it becomes a more powerful off-road vehicle, is not fragrant?
Within 150,000 recommended a car, wife novice to drive, commute to pick up children.
The third question talked about buying a commuter car for his new wife, and the friend didn't seem to have found a clear goal to buy a car.
In fact, this problem can be seen in this way, first of all, you need to buy a car for your wife, and secondly, the main purpose of this car is to pick up and drop off children from work every day.
Then the models on the market that can meet these two needs are actually very clear.
For girls, they generally like some high-value models, and cute and fashionable cars can usually impress them. And it happens that your wife is a novice, so a small car with a good view will help reduce the pressure on the novice to go on the road, so that the goal of choosing a car is clearer: a fashionable and good-looking car.
A budget of 150,000 can't buy a MINI, but it's easy to buy a BYD Dolphin.
This BYD's latest pure electric car is stylish enough in terms of appearance and interior design, and its appearance alone is one of the best in the domestic market. The pure electric mileage of 301-405 kilometers can also basically meet the needs of daily commuting, picking up and dropping off children and buying vegetables.
Of course, if you don't have a fixed rechargeable parking space and are not too cold for pure electric models, the professor thinks that the Fit of GAC Honda (Figure 1) or the LIFE of Dongfeng Honda (Figure 2) are also good choices.
The two models are essentially indistinguishable, and as the fourth generation of the Fit series, they both bring many useful upgrades in terms of daily convenience.
In particular, the two large triangular windows of the A-pillar play an important role in improving the field of view and reducing blind spots, and are very friendly to novice drivers.
Of course, the Fit original factory does not provide reversing images and parking radar is a more obvious shortcoming, which needs to be solved by aftermarket installation; while LIFE has provided reversing images, which is relatively a better choice.
From the professor's point of view, in fact, it is good to reduce the budget and consider buying a second-hand car.
After all, novice drivers will inevitably encounter small bumps on the road, and if they drive a cheap second-hand car, it will not be too painful.
Will it be dangerous for hydrogen fuel cell vehicles to leak hydrogen tanks?
The last problem is more hardcore, involving the safety of hydrogen storage tanks for hydrogen fuel cell vehicles.
In fact, hydrogen, as a very flammable gas, must be very dangerous after leakage, but the question is whether it is prone to leakage?
According to the technical information learned by the professor and what he has seen and heard in the past visits to the hydrogen fuel cell technology center of the car company, the hydrogen fuel cell vehicles that have entered mass production and are sold in individual markets use very hard-core materials for hydrogen storage tanks.
Carbon fiber, Kevlar and other things that sound very advanced, high-pressure hydrogen storage tanks have them, and there are many; these materials combine to give this jar the strength to withstand bullets.
Even a bullet can't penetrate it, so how can a mere collision destroy it?
If unfortunately encountered a fire, the temperature insulation material of the hydrogen storage tank can also be a good way to avoid the temperature rise in the tank, resulting in excessive pressure; if the pressure in the cylinder really breaks through the danger line, these hydrogen storage tanks are also equipped with special emergency pressure relief devices.
These pressure relief devices will release the gas in the cylinder in time to reduce the pressure, of course, these hydrogen gases are likely to catch fire when they are discharged, but at least it can ensure that it does not explode.
The above is the entire content of this issue of the program, welcome to ask questions at the bottom of the article, the professor will select some questions in the next program for in-depth answers!
