Ferrari descent SUV

Ferrari's father Enzo Ferrari was the test driver of the Alfa Romeo team, Alfa Romeo and Ferrari are inextricably linked. With the Italian luxury brand, Alfa Romeo launched the first SUV model - Stelvio, the recent brick uncle had its
deep test experience. Today's test is its four-wheel drive system Turbocharger to see how the performance?
The test of the model is Alfa Romeo Stelvio 2017 2.0T 280HP Deluxe Edition, belong to the top models, the official price of 4.80 million yuan. Stelvio is equipped with full-time four-wheel drive system.
Stelvio's four-wheel drive system is similar to the GLC sedan SUV that was previously tested, and is the urban SUV setting. The central differential is a gear-type structure, which is theoretically capable of 50/50 power distribution.
In addition, Stelvio offers three driving modes to choose from, namely, energy saving mode, normal mode and motion mode. You can switch through the knob at the bottom left of the gearbox at any time.

Toyota made with wood pulp

Japanese car prices recently collective "black", wait, this is not derogatory words, saying that people frequently resorted to black technology.
Honda developed and produced 10AT automatic transmission at very short speed, 11 speed transmission is also jogging ready to report; Mazda released the e46 m3 coilovers second generation of Chi Chi blue sky engine technology, compression ratio will be as
high as 18: 1, so that your home to buy a car Find the feeling of F1.
These two days, Toyota has focused on throwing two new technologies, one of which is expected to subvert the future of man-made timber.
Variable compression ratio technology
Let's talk about a little bit of conventional, variable compression than the engine.
Toyota has recently applied for a patent on variable compression technology. Dynamic Force Engine, which is also the name of the new engine launched this year.
Variable compression ratio technology and variable valve timing technology, variable gas phase technology together, are through the physical changes in the engine base parameters to optimize the fuel efficiency of the technology.
The natural air intake version of this engine is 13: 1, the hybrid version compression ratio of 14: 1; these two versions also have the world's highest thermal efficiency, natural intake version is 40%, hybrid version is 41%. Hidden in
the high compression ratio, behind the high thermal efficiency, as well as the Japanese black technology.
Equipped with variable compression ratio of the engine car, in the normal output conditions, the compression ratio can be reduced to 8: 1, in the need to reduce fuel consumption, the compression ratio will be increased to 14: 1. It seems
that the new engine compression ratio will be as high as 18: 1 seems to be more powerful, but Toyota's compression ratio is dynamic, more intelligent, to meet the needs.
Toyota this new engine maximum power of 268 horsepower, the maximum torque of 390 Nm, it sounds quite vigorous.
However, Toyota is not the first to make a variable compression ratio of the engine manufacturers, but it is the closest to the production status. The first to make a variable compression ratio, but also the Japanese manufacturers -
Infiniti. Infiniti uses a multi-link structure to solve the engine cylinder adjustment needs, but this structure is very complex, the complex meaning is the first, its manufacturing costs will be high, is not conducive to mass
production; second, its failure rate may also High, the same is not conducive to mass production.
Toyota this time is to solve this too complicated problem. Toyota is more from the shape of the piston to start to solve the problem of changes in the engine compression ratio, so that moving parts than Infiniti significantly reduced
manufacturing costs and failure rate naturally reduced. In fact, this idea of ​​Toyota compared with the current conventional engine, and did not increase the number of complexity.
Earlier news that Porsche will be put around in 2017 variable compression ratio engine, design ideas and Toyota similar. But it is clear that the Japanese once again won the first place.
Later, our car may be wood products
Made a car made of wood, and so on, are you sure that this is not a small fire in the country?
No, of course not, this is the world's largest weaving machine manufacturer to create a new coilovers concept car. Excuse me, is the world 's largest carmaker' s new concept car (what 's the difference between the previous one?
Toyota has developed a new lightweight material that sounds very light: wood pulp material. This wood pulp material will be used to make automotive housings, interior parts and other parts that are available.
This kind of wood pulp material is not simply get mixer stir water mixed with wood. Toyota This material is known as nano-cellulose (Cellulose Nanofiber, referred to as CNF), by Toyota, Denso (Japan Denso) and Kyoto University jointly
developed. CNF material stiffness is 5 times the steel, the weight is only one-fifth of steel.
This material and the liquid mixture will produce a lot of sticky, in the field of automotive manufacturing is very suitable for the production of body, a substantial reduction in weight, the future of electric vehicles in the same
battery energy situation significantly enhance the mileage; But also make the body more durable, really double-edged sword.
Obviously, compared to other lightweight materials, such as aluminum, magnesium alloy and carbon fiber, CNF is more environmentally friendly and more sustainable development significance.
So, when is such a good material mass production? Do not worry, first solve the cost problem to say. At present, 1 kg of CNF material is about four times the cost of aluminum alloy material, you obviously do not want to spend a Ferrari
price to buy a Toyota, right? So we need to wait until the technology is mature and suitable for large-scale production to reduce costs, in order to enjoy the benefits of wooden cars.

2019 Colvik C8 or 2018 at the end of the debut

According to legend, the US national treasure sports car is scheduled for 2018 North American auto show starting, but also may follow the trend will launch pure electric version.
Appearance, layers of camouflage did not reveal too much detail, but for a super run only, the most important natural is its power side, at the same time, we can also clearly see from the figure, Colvik C8 to change the engine.
In fact, GM has long been in the study of the new layout of the engine, and even the first plan to be completed in the C7 such e46 m3 coilovers a major change. But in 2009 when the United States broke out of the bankruptcy of the car prices, GM did not
escape; so in this storm, the Corvette C7 mid-engine plan so it would be.
Prior to the general engineer "accidentally" revealed, C8 is likely to be set in the front of a transparent window, you can directly see the inside of the new engine. But these spy photos can be captured in fact very simple, according to
the "informer" message, GM test C8 time deliberately arranged at night, just do not want to "spy" capture the actual performance of C8. And its Kentucky factory also suspended the factory for 18 months.
There is also a message that the Corvette C8 is going to have a 6.2L V8 engine with coilovers a DOHC (double overhead camshaft), code-named LT5. If the situation is true, then the C8 will be the 1995 after the use of DOHC technology engine
Corvette family models.
As for the specific power parameters, taking into account the power of the previous generation C7 Z06 has more than C6 ZR1, reached 650, C8 must only be higher, do not know this change in the Corvette can cause Nissan GTR The sensation.
More new car news please pay attention to Phoenix car follow-up reports.

Will Audi lead Mercedes-Benz?

Look at the development of luxury brands, the basic value of the competition has come to an end, whether it is German Department of Mercedes-Benz BMW Audi, or Japanese Lexus Acura Infiniti, family design is very city, and the basic has been stereotypes. Like the BMW's kidneys, with a few decades, it is estimated that the next few decades will not change. So the next round of luxury brand competition, will be a technical technology Competition.
This one contest has two key points, the first is the new energy, the second is the intelligent automatic driving, now see who can dominate really hard to say. Let's take a look at autopilot first.
According to a foreign media statistics, the current stage of automatic driving technology fit bmw e46 coilovers for sale patent competition, the German enterprises still dominate the number of patents in the top ten enterprises inside, there are six German companies, suppliers Bosch largest patent, the German mainland third. Car companies side is Audi, BMW, Volkswagen, Daimler. The remaining three are US Ford, GM and Google. Japan Toyota ranked seventh.
May be a lot of people noticed that in the autopilot practice the furthest and most deep Google, the patent actually bottom. Car companies are hidden, especially the Audi car dealers ranked first.
Audi is still in the global sales of Mercedes-Benz BMW in the back, then enter the new consumer era, Audi can lead it? At this stage of the luxury brand competition, are the traditional technology competition, such as BBA's three pieces, four-wheel drive technology, interior electronic accessories, interior and exterior design luxury and so on. Automatic driving technology may not be the same, directly related to traffic safety.
Audi's autopilot technology is the most complete use of the new generation of Audi A8, Level3 can achieve automatic driving, the driver only need to be responsible for the emergency situation. In fact, the new A8 is nothing but equipped with sensor sensors, all kinds of radar, night vision system, laser, camera and so on.
The new 7 series, although there are gestures and other technical control configuration, but in the eyes of consumers, can only be said to be intelligent driving. Mercedes-Benz S-class models equipped with Intelligent Drive driving support system, said that the actual can achieve four automatic e46 m3 coilovers driving function, but Mercedes-Benz does not emphasize this point, because the facelift technology application will not change too much.
So the number of patents does not represent the actual technical matching and application capabilities. Now the number of patent applications of independent brands, has more than overseas brands, the actual strength we all know. Luxury brand is not necessarily the advantage of the same Audi, at the starting point of the case, as long as the independent brand effort, or have the opportunity to become world-class.

Who is driving autopilot?

In the development of automatic driving competition, Google and other technology companies received a lot of attention. But a new study shows that these technology giants may be difficult to beat traditional car manufacturers and parts suppliers.
In order to understand which companies are leading the development Bmw e46 Coilovers of automated vehicle technology, the German Cologne Institute of Economic Research has identified and analyzed 5839 patents over the past seven years.
As we have seen in the table below, the traditional car manufacturers and parts suppliers - the German three strong - are leading automatic driving technology, rather than the technology companies we see.

Common use of steel and its recycling

The growing use of steel in the automotive industry is often used to manufacture various types of automotive components. So, what is the use of steel in the automotive industry? What are the advantages of steel?
Common use of automotive steel
At present, many vehicle parts are made of steel, the proportion of more than 50%. Most of the steel is used to make the body of the vehicle skeleton (skeletal body), which is known as the white body (body in white), the parts for the manufacture of other parts of the vehicle laid the foundation. White body is usually used in a variety of different types of steel, different grades of steel, its corresponding strength, hardness and other performance indicators are not the same, the use of steel GT3582 turbo manufacturing vehicles, the cost-effective, the material corrosion resistance outstanding.
Steel can be made into different shapes, with a certain material development space, to ensure that it meets the relevant requirements of safety regulations. Vehicle parts will also have an impact on driving control, the choice of steel not only to ensure safety, but also enhance the overall performance of the vehicle.
Many people worry about the sustainability of steel after long-term use, for the automotive industry, this is a very important issue. Over the years, reducing the impact of steel production on the environment has always been an important issue. In recent years, the steel industry has tried to control and reduce waste and exhaust emissions, the fit Subaru Impreza Coilovers destruction of the environment has been reduced a lot.
As energy-intensive and carbon-intensive industries, need to pay a great effort, its difficulty is not small. However, the current emissions are only carbon dioxide, which means that compared to other metal manufacturing methods, the current waste reduction to achieve the relatively low degree of difficulty.
Recycling of steel
In addition, the steel can be highly recyclable. In fact, the material can be infinitely reduced to its original structure, which will bring huge benefits, which means that the number of steel products that can be put into production will grow, and many old cars have become the source of steel and, to a certain extent, The issue of sustainability. Even better, in the recycling process, the steel will not degrade, can use recycled steel (secondary steel) to produce all kinds of products, including vehicles.
While the attractiveness of other materials as steel is so big, mainly the recovery and reuse of the more difficult.

After the new car running period, the fuel consumption will decline?

Run-in period is a lot of new car owners are more concerned about the first three thousand kilometers of a car running well, the overall life of the car and the situation is better than running a lot of good car. Some owners believe that the run-in period fuel consumption is relatively high, because there is this concept in the former, for the run-off high fuel consumption is not too concerned about the hope that after the run-in period just fine.
This view is wrong, in fact, should be concerned about the run-in period of fuel consumption, because in accordance with the normal running rhythm, the most fuel-efficient way of driving is generally the best way to run. Such as no emergency braking, no hurry to speed up, these are the basic rules of green driving, but also GT2871 turbocharger the run-in period of driving requirements. From the run-in period to raise a good driving habits, naturally, after the fuel consumption will continue to go low. If you feel that the run-in period had high fuel consumption, do not care, one is not conducive to the vehicle running, the second is to develop bad driving habits, after the fuel consumption is not down.
Indeed, after the run-in period will indeed decline in fuel consumption, but do not expect too high, generally can reduce the 3 to 5% on the good, the best way is to run into a good driving habits.
How to drive during the run-in fuel?
1. In the use of the engine speed can not be too high. The general speed of not more than 3000 rpm, if it is not more than 3,000 automatic transmission
After the new car running period, the fuel consumption will decline?
2. Can not keep a stall for a long time or a long time low-speed driving. All the cars in the low-speed driving, the actual burden than the speed of driving to large, so the run-in period should not be long-term at 60 km per hour run-in. We must gradually increase the speed. At the same time, if you have been running at 80 km Turbocharger per hour after the run-in period, the sudden increase in speed, but will make the new car does not meet, so to gradually increase the run-in period of the highest speed. Automatic transmission of the car, because it can not manually shift to determine the run with the specified file, it can only be achieved through the driving speed.
In short, run to even speed drive, 30km / h, 60km / h, 80km / h, 100km / h, this level must be stable running.
3. Body can not load too heavy driving. The new car running when the body the lighter the better, because the load is too heavy on the car will be damaged.
