Double clutch transmission in the low speed prone to frustration,
Ignition Coils the main reason is the dual clutch transmission without hydraulic torque converter, but rely on friction directly to the torque transmission to the drive shaft, although there is no hydraulic torque converter to bring the power loss, But the friction plate is not the role of hydraulic torque converter buffer, the two sets of clutch plate in the shift operation, easy to produce a sense of impact.
Similar to the manual gearbox, there are similar semi-linked states in the power transmission process of the dual-clutch gearbox, in order to reduce the wear of the clutch plate. So TCU software engineers will let the clutch plate and friction plate as soon as possible, this time if the engine output speed and transmission output speed difference is relatively large, there will be frustration.
One solution is to optimize the hydraulic control unit, through the hydraulic
Air Suspension cylinder to push the clutch plate to friction, reduce vibration, thereby reducing the generation of frustration. Volkswagen code DQ200 7-speed dry dual-clutch gearbox using mechanical control arm and sleeve squeeze diaphragm spring deformation, from the structure point of view of its transmission efficiency is higher, optimized for the hydraulic system to promote, to better filter vibration, Thus further reducing the generation of frustration.
Software control, you can optimize the dual-clutch transmission of the shift logic, through the actual shift data to determine the correction of bias, can help double-clutch transmission torque and separation of the control position more accurate, low speed ride in the use of the process Gradually improved.
In addition to the above mentioned gearbox optimization, the vehicle ride comfort is also related to the engine. The torque response speed of the engine is also one of the factors that affect the driving experience.
At the same time, the powertrain mounting design also has a certain impact on the driver's perceived ride comfort.
Will be listed on the Chuan Qi GS7 superfluous or even more powerful? Thanks to Chuan Qi GS8 hot, "reduced version of GS8," said the GS7 since the debut, the heat has been unabated. According to buy car Jun understand, GS7 will be officially listed on August 26, then so concerned about the GS7 GS8 can copy the success of it? What is the GS7 product performance? Chuanqi GS7 appearance and interior design and GS8 is very similar, and the biggest difference between the two is only GS7 only five models, no seven models to provide, followed by the body size, GS7 only car length and wheelbase shorter than the GS8 80mm, width and height exactly the same as GS8. In addition, because the GS7 is positioned lower than the GS8, the GS7 is equipped with only one set of 18-inch wheels, while the GS8 is equipped with a 19-inch hub. At the same time, GS7 deputy driver's seat panel also uses the imitation carbon fiber material, compared to GS8 wood grain material, visual effect is more young. In terms of power, GS7 will provide 1.8T and 2.0T two engines, matching 6MT and 6AT gearbox, which 2.0T +6 AT powertrain is also equipped with GS8 powertrain, and 2.0T displacement models will Match the same four-drive system as the GS8. This is to say, Chuan Qi GS7 and GS8 positioning and product performance are not far behind, and GS7 pre-sale price of 15.58-22.98 million, the starting price is only cheaper than the GS8 (16.38-25.98 million) 8,000 yuan. In this view, GS7's price is not very high. Of course, GS7 listed after the actual price is likely to be lower, but it is with the GS8 price is bound to highly coincide. In the case of almost no difference between the two products, it is easy to give consumers the choice of difficulties. The worst result is that GS7's sales are less than expected and GS8's sales are shunted. So compared with competing products, GS7 whether there is any advantage? Even if the Chuan Qi GS7 after the listing of the price has been reduced, but the car that the magnitude is not large, the final price is expected in the range of 14-21 million. Therefore, GS7's main competitor is Harvard H7, Changan CS95, as well as joint venture brand Chevrolet explorers and Skoda Kodiak. First, compared with the Hover H7 and Changan CS95, in terms of spatial performance, Chuanqi GS7 body size and the other two compared to no advantage, and GS7 wheelbase is only 2720mm, and Hover's H5 2850mm and Changan CS95 2810mm Far worse, we can see GS7 ride experience is not better than Hover H7 and coilovers Changan CS95. Followed by the engine, with the same 2.0T displacement, but Chuan Qi GS7 maximum horsepower than the other two less than 30, the effect is the power performance is more fatigue. Fortunately, GS7 in terms of torque to pull back a little score, 1750rpm will be able to get the maximum torque, while the duration is relatively long, so GS7 is more suitable for driving in the city's congested roads. And compared with the joint venture models Chevrolet delchers and Skoda Kodiak, for the time being regardless of other, just look at the brand and reputation, in the face of the price of almost the case, most consumers are more inclined to choose joint venture models, so, GS7 in the future to face the pressure is not small. Chuanqi GS7 how to win in the competition? Chuanqi GS7 want to highlight the tight encirclement, there is no doubt that the adjustable coilover most important factor is the price. Chuan Qi GS7 current price and GS8 price is not much difference, Moreover, GS8 also has a third row of seats, more in line with the needs of most consumers car. So, Chuan Qi GS7 want to get excellent sales, in the pricing must be close to the people. And buy a car Jun feel GS7 starting price should be set at 13.5-14 million between the Bihao H7, Changan CS95, deliberation and Kodiake and other models from the price of the formation of the price advantage of 10,000 yuan, This is competitive. In addition, the transmission capacity problem is also a factor can not be ignored. Earlier Chuanqi official announcement said that limited by the letter of love 6AT capacity problems, resulting in GS8 production down to 7000 / month, and GS7 must be loaded with 6AT gearbox models, if the capacity is insufficient, pin! Buy car Jun said Compared with the competing products, Chuanqi GS7 product performance is at a disadvantage, coupled with high pre-sale price and automatic transmission capacity Turbocharger constraints and other factors, the current situation, GS7 prospects are not clear. Of course, if the GS7 price is more close to the people, by virtue of the good quality of the brand and the GS8 Aura, GS7 still have the odds.
Today, most of the cars are not four-wheel drive, most of the car is used in the front drive drive, it is because the front drive has a simple structure, low cost characteristics.
That being the case, why is there a more complex structure, the
Turbocharger higher cost of the rear drive it?
This design must have its truth, after driving in many ways are better than the front drive, such as extreme acceleration and extreme climbing ability.
First of all, we simply understand the difference between the front and rear drive.
Their distinction can be literally simple to understand, the front drive is only the front wheel is responsible for driving, the car is pulled by the front wheel, for example:
The same, after the drive is behind the wheel is responsible for driving, the car is pushed by the rear wheel, such as:
From the metaphor of the figure in addition to the driving force of the two in the former one after the outside, it seems that there is no difference.
Indeed, in most cases, the front and rear driving is not much difference, but encountered steep slopes, rapid acceleration of the case, the difference between the two appeared.
First of all we have to know, the engine gave the wheel power to have the traction on the body, but this traction is impossible to increase.
That is, when the traction over the wheel and the ground when the maximum static friction, there will be the phenomenon of wheel slip. And this maximum static friction force is derived from the wheel on the road pressure.
In the case of steep slopes, the uphill capacity of the rear drive will be better than the front drive. The reason is that the front wheel is easier to slide when the front wheel is uphill.
Because the slope of the ramp will also make the car has a backward flip trend, making the rear wheel and the ground pressure is greater than the front wheel.
In simple terms is the uphill, the vehicle center of gravity is to rely on the rear of the body, the front wheel is not so much weight on the slope, can not suppress, the wheel is easy to slip. On the contrary, after the drive is not so
easy to slip. (Extreme climbing case)
Similarly, in the case of rapid acceleration will occur this situation, because
adjustable coilover when the car forward to accelerate when the body will drive a wheel forward torque, while at the same time, the wheel gave the car a backward The moment of
rotation.
And this reaction will make the rear wheel and the ground pressure becomes larger, the front wheel and the ground pressure becomes smaller. This is why the super run is mostly behind the drive, or even four-wheel drive reasons.
Then the car is certainly the rear wheel "push to go" than the front wheel "pull away" okay?
In fact, can not say so, although the drive in many aspects than the front drive more advantages, but the precursor is not nothing.
Such as in the rain and snow days slip phenomenon, after driving more difficult to control than the front drive. Also through some of the way through the road, the
Turbo for sale front drive will be more easily "climb" up.
So can only say that each has its own advantages and disadvantages, but after the cost of driving a higher cost, the price is more expensive it really has its truth.
The first few days before the first Tesla Model3 completed the delivery ceremony, Truss CEO, chief designer all to the scene, for everyone to explain Model3 the most accurate "her family" data, there are a number of stylish and elegant
"bride" Standing there, that gas field full of scenes,
coilovers so small series of small bang bang jump.
Model3 different charm, the vehicle consists of a total of 10,000 components, the design is very difficult to inherit the essence of Model S and X, and make it more concise and elegant.
Model3 still inherited the Truss family power on call, deep step on the surging output characteristics, 5.1 0-100 km acceleration time, the maximum speed of 225 km / h, while the standard version is 0-96 km hour acceleration 5.6 seconds,
The maximum speed of 217 km / h. This power data is very Terras. Model3 suspension follows the front double wishbone / rear multi-link structure, to improve the handling performance of the theoretical help. As for the elimination of the
ModelS / X on the air suspension, instead of conventional spring, the seat side support is relatively weak.
15-inch touch screen than the ModelS / X 17-inch slightly smaller, but because of the use of horizontal design, people will produce a seemingly greater illusion. Model3 to cancel the traditional dashboard, the layout of the design to
adapt to unmanned, so the information is displayed on the touch screen, but the screen partition is reasonable, speed, gear and other important operations are placed on the left side of the white area, the right side Leaving the second
important navigation and settings. There are only two knobs on the steering wheel, but it is versatile and can be given more functionality depending on the software upgrade.
Top with the models of the complete windshield glass, in addition to the middle of a piece of reading lights placed outside the vertical roof, bringing a very good lighting and technology. Interior air conditioning beyond the concept of
partition, you can use your fingers on the screen directly to any area set the wind
coilovers for sale temperature. Vehicle storage space is also very much, before and after the rear are provided with two USB ports.
In the past, all kinds of Terras models are always Tucao key for U disk, Model3 changed the design concept, developed two models to open the door. The first way is to use a bank card size "black card" chic brush open the door, the second
you can it your Model3 and mobile phone paired, as long as the phone appears in the car's Bluetooth distance, the vehicle will automatically unlock.
It can be noted that the side ratio of Model3 is different from that of the BMW 3 Series and the Mercedes-Benz C-Class equivalent: the front axle center to the front door column (the so-called Dash to Axle) is much shorter, since there
is no tradition The central gearbox and drive shaft required to drive the petrol truck.
Model 3 is a coupe-style design. But in fact the car height of 1.44 meters, is completely the level of orthodox sedan. More full roof arc brings more head space, of course, also makes the side lines more "rounded", the roof like a small
fat man.
Chassis, Model 3 is limited by the cost, not follow the Model S / X all aluminum body, instead of steel and aluminum mixed structure. But surprisingly, Model 3 achieved 1.6-1.7 tons
The Model 3's two mileage items are not the same:
Life 354km, priced at 35,000 US dollars version: 1609kg
Life 499km, priced at $ 44,000 Edition: 1730kg
This means that the high-end version is to increase the battery capacity to improve mileage, rather than in the low-end version of the software through the lock life. From low to high life upgrade need to increase the battery from the
hardware, rather than unlock the OTA upgrade can be. This team is a low-powered version of the owners is good news: do not have that part can not use the battery, drag the little mileage.
Taking into account the Tesla vehicles will increase in this year, Tesla will build a large number of super charging stations and service centers, super charging station existing 6124, by the end of this year exceeded 10,000, next year
more than 15,000. At the same time Tesla will create 100 new service centers, and began in the global deployment of mobile maintenance vehicles.
Mobile maintenance vehicles can be any customer in any convenient place to provide services, even on the road, remove the tire and other services, and even can provide software upgrades and other services, it is because Tesla found 80%
of the owners of the problems encountered are Can be resolved through software upgrades, these mobile maintenance vehicles will even provide coffee and children's toys, Tesla
Turbocharger said mobile services will become the future direction of the
service
Finally, we have done the best generalization of the model 3 in a section of Masque's story: Today is a GREAT DAY for Tesla! Model 3 is a GREAT and AFFORDABLE eletronic car. There are great gasolin car, great expensive car (Today is an
important day of Tesla, Model 3 is a great and close to the people of the electric car, the world has a great petrol car, a great luxury car, but never Great and close to the people of the electric car).
Now the market is the hottest German cars, either Japanese cars, or their own brand, how can not eat the French car hot. But now the wind is also a major shareholder of PSA, if the French car in the country has been maintained before the
weak trend, then it is too much to go. So the French car is now not
Turbocharger only start the latest and most advanced new models continue to import China, and more concerned than ever before the needs of Chinese consumers, but also into the seven
SUV this area. Peugeot 5008 arrival, that is, they want to prove in the country Jedi fight back. 18.77-27.97 million price, compared to the main models such as Highlander also cheaper a big cut. But can it succeed? No matter so much, we
come to see it faster.
Its three-dimensional size of 4670 × 1855 × 1655mm, in this level is definitely not a big calculation, or even only a little bigger than the compact level of the car, but the wheelbase also has 2840mm, but its appearance at the same
level In the absolute count on the level of the. Not only looks both head, and not bloated, like a person only compact muscles, no fat the same.
Details, the 5008 also play a legal car good at showing off the capital, the shape of the headlamps like a claw, even if the internal use of ordinary halogen lights, there is a crystal clear feeling. Taillights are the same, using the
same as the lion claws of the three groups of rectangular shape, it can be said that a new generation of Peugeot's iconic design language, it is too good to read.
Interior design is also fully equipped with the same style and 4008, the cockpit to the
coilovers driver as the center of the layout, and a sense of full of science and technology, and even the size of the steering wheel than the same level of
small. To know that this is a flagship 7 SUV ah, the law is still the original car does not change, in the 5008 to show off the main driving control elements.
The layout of the functional area is very simple, most of the functions of the dashboard and center console are displayed through the LCD screen, and the dashboard also incorporates the navigation display function, especially the
transitional animation is very beautiful.
Small size of the steering wheel behind with a shift paddle, which also highlights the Peugeot has always focused on driving the idea.
Shaped like a general joystick electronic gear lever, but also Peugeot main design selling point. Next to a dynamic mode of the knob, with paved roads, snow, rugged road and sand and other four modes.
His seat design is a lot of selling, the first is the back of the space itself, although not as the level of the model is spacious, but the legs are still enough space. And a large area of panoramic sunroof, rear exhaust is also a
favorite of many people.
And the middle row of seats is also very unique 4: 2: 4, so that in the row of seats fixed child safety seats, the third row of people to facilitate the care.
The third row is two completely independent seats, space or enough. But it is the biggest use, or can be a separate demolition, this way you can camp in the wild when the comfort of the camp, but this is not useful for the use of people.
5008 power system, the main hit a 204 horsepower 1.8T THP turbocharged engine, matching love letter of the 6-speed tiptronic gearbox. The chassis, the law car continues to adhere to the former McPherson, rear torque beam suspension
layout, which also makes it the whole department only front front layout, which is afraid to become a big deal of 5008.
Dior seems to, although the design of this car is really amazing, and the price threshold is also low enough, but it is still a lot of details of the design of the law has a unique parade, but the traditional and some of the traditional
needs of people out of tune. 5008 can rely on cost-effective in the market to tear a hole? Dior is still somewhat pessimistic. However, for those who need long-distance travel,
Turbo for sale the seven features have just need, but do not want to give
up driving pleasure, 5008 may be a good choice.
Recently, Maserati helped the Venice Heritage Foundation and the American Cheap Turbo Kits Louvre Friendship Association, successively in the Louvre Museum in Paris and Venice's historic Scuola Grande della Misericordia held two respectively "Grand Night" (LaGrande Nuit) and "sweet Life "(La Dolce Vita) as the theme of the grand charity dinner.
As a partner of the Venice Heritage Foundation, Maserati not only for the guests to provide a luxurious and comfortable concierge services, but also customized a unique Quattroporte President GranLusso luxury car version, for the "sweet life" dinner live auction. The two dinner auctions are used to repair the Gallerie dell'Accademia and the Anneof Austria apartments in Paris.
Maserati's Quattroporte President's car redefines luxury and sport, providing a unique experience of comfort and comfort for the driver. This is a special custom for the Venice dinner special Quattroporte president car GranLusso luxury version, equipped with a 389kW V8 engine, 100 km acceleration only 4.7s, the maximum speed of up to 310km / h, for the same level of the car in the crowd. It is the first time using three layers of paint technology to enjoy the enjoyment of pure white appearance, together with the noble black high-grade leather interior, the car's carbon fiber decoration, suture the beautiful gray pins and seat headrest on the delicate and elegant embroidery Trident logo, all Revealing the elegant luxury; the same time, in order to pay tribute to the Venice Heritage Foundation, the president of the car is still in the center console with Venetian Heritage (Venice Heritage Foundation) logo custom plaque, no doubt become the most eye-catching scene The focus. In the evening, this unique car was shot by Jill Schlenker and Calvin Schlenker from Houston.
Maserati Global CEO Mr. Red Big Grande on behalf of the brand attended the feast, and personally Maserati Coil Over Shocks car key to the hands of the new owners. Other celebrities attended the dinner include BeccaCason Thrash, Managing Director of the Heritage Foundation, Toto Bergamo Rossi, Christopher Forbes, Vice-President of Forbes Publishing Group, Duchess of Segorbe, artist Fabrizio Plessi and his wife Claudia, and Rodman Primack, director of design for Miami Many guests.

See the title, may be a lot of people will be surprised a moment, the battery cost reduced it, change what pattern it? Here to first popularize a little knowledge: power battery industry that only when the battery cost is less than 100 US dollars / kWh below, pure electric vehicle profitability is possible. And recently, Dr. Peter Mertens, senior vice president of Audi R & D, unexpectedly disclosed that Engine Turbochager Audi's battery purchase costs have reached € 100 / kWh ($ 114 / kWh). I am afraid to rely on the cost advantage of the expansion of the Tesla advantage has disappeared. Not long ago, Audi has announced its electric strategy, it is expected that Audi's first pure electric SUV t-tron quattro will be listed at the end of 2018. Subsequently, Audi will continue to bring a few models of pure electric vehicles, and all this foundation is undoubtedly inseparable with the cost of the battery Mertens said in an interview with the German media: "We have adopted a high to low strategy, because the market segment (electric car market) has a large number of Audi potential customer groups.Currently, this model (e-tron quattro) The cost of the power battery is about € 100 / kWh. " Audi e-tron quattro battery 100 euros / kWh cost has Aftermarket Turbo been low to "incredible". The electric vehicle industry pioneer Tesla, the cost of the battery is still $ 155 / kWh. So what is the industry average? Earlier this year, McKinsey released a car power battery research report, note the following figure, the report shows the average cost of the battery from 2010 1000 US dollars / kWh down to 2016 $ 227 / kWh. It can be seen, Audi for pure electric field research and development, has been leading the industry, and leading more than one star the slightest. And Audi's life to reduce battery costs, not only shows its advanced technology, more will directly reduce the e-tron pure electric vehicle sales price and the cost of the use of passengers, which is looking at the article for you, is Tangible benefits. Audi will launch three pure electric vehicles in 2020, and plans to 2025, to achieve pure electric vehicle production accounted for 25% of the total output of 35% target. With such a power to the cost of the battery, I believe that such a plan is not just "dead knock" Tesla, but also in the pure electric field to do the leading boss, we will wait and see.
Model 3 is Tesla's first electric car for the mass market, which starts at $ 35,000 Engine Turbochager (about 23,7944 yuan) car has been sought after by many users, orders have reached 300,000. But want to have its users may be patient waiting for some time, Tesla announced on Monday, the company in the first half of 2017 a total of 47,100 electric vehicles, only reached the official expectations of the lower limit. After announcing the news, Tesla's share price fell 2.5 percent to close at $ 352.62. Why is the production capacity so low? Tesla said the serious shortage of new battery packs limited car production. However, Tesla said that follow-up will speed up production, by the end of this year before the implementation of 5,000 production planning per week, 2018 to achieve 10,000 per week production is expected next year can produce 500,000 cars. 
Recently, a group of new generation of public POLO Turbo Exhaust Manifold sedan version of the effect of the model was exposed, the new car was named: Virtus, is expected in November this year, officially put into operation in Brazil.
Appearance: Virtus and hatchback models compared to not much difference. In addition, Virtus Coilovers will share the MQB A0 platform with the Polo hatchback, which will also be the first product to be supported by the MQB platform for the Latin American market. Configuration: It is reported that buyers will be able to choose more high-tech features, such as automatic cruise control, emergency stop assistance and blind spot detection.
Power: Volkswagen Virtus will receive a variety of power groups, such as 1.0L TSI engine and 1.6L MSI engine, in addition, the concern GTI models or will be equipped with 2.0-liter turbocharged four-cylinder engine, the maximum power of 200 horsepower.
According to Juergen Stackmann, director of global sales for Volkswagen, Virtus and Polo will not sell to the United States because it is too expensive. Stackmann believes that the US market is a small car to rely on price advantage to win, and Polo models in the United States if the competition will invest too much money. In Germany, the car is about $ 14,500 (about 10 million yuan)
It is reported that the new car will be based on MQB platform to build, is expected to launch a variety of three-cylinder, four-cylinder turbocharged gasoline and diesel engine models.
Appearance: According to the rendering of this view, Turbo Manifold the new car compared to the cash models compared to the body lines more sharp, angular more obvious, while the new car follows the classic family hexagonal front grille, with a new design before the bumper, The vehicle is more fashionable sports atmosphere.
Configuration: the new car interior will use a new design language, and is expected to match the popular LCD instrument and the latest MMI information system. While Ignition Coils the new car or equipped with ACC adaptive cruise function.
Power: According to foreign media speculation, the new car is expected to launch a variety of three-cylinder, four-cylinder turbocharged gasoline and diesel engines, while plug-in hybrid version of the models will be launched. It is reported that the new car is expected to open in September this year, the Frankfurt Motor Show debut, and listed next year.
