When it comes to the famous MLB Evo platform, everyone knows it. So, do you know which medium and large SUVs have been built based on the MLB Evo platform? Counting, there are Bentley Bentayga, Porsche Cayenne, Lamborghini Urus, as well as Audi Q7, Audi Q8 and Volkswagen Touareg. The most expensive of these models is the Bentley Bentayga, Its top model has been as high as 3.136 million yuan, followed by Lamborghini Urus, its price is 2.94112 million yuan, if you add the optional, it may be more expensive than Bentley Bentayga, the cheapest price is volkswagen Touareg, 59.18-84.58 million yuan price range plus a lot of preferential strength, its entry price has fallen to less than 500,000 yuan, it is reasonable to say that Touareg is still very cost-effective, it and Bentley Bentay more platform, but cheaper than Audi Q7, why is this high-end SUV not welcomed?
In the end, or the brand, the Volkswagen brand to support such an expensive price or slightly "more than enough and insufficient strength", may be 300,000 yuan volkswagen everyone can still accept, once the price reaches 500,000 level, why not buy luxury brands? In addition, the body size of the Volkswagen Touareg is not large, its length, width and height is 4878 * 1984 * 1686mm, the wheelbase is 2899mm, the size is smaller than the Volkswagen Tuang, some friends who do not understand this car also think that it is "Tiguan L", that is, only from the appearance part, Touareg does not reflect its due sense of grade. So, compared to volkswagen SUVs such as Tiguan L and Tuon, what is the difference between Turui and Turui?
The most obvious difference is that as mentioned at the beginning of the article, their platforms are different. Touareg is based on the MLB Evo platform, and it is the only Volkswagen SUV built on this platform, and other Volkswagen SUVs (fuel vehicles) are built on the MQB platform. It's not so much the difference between the Touareg and other mass SUVs, but rather the difference between the MLB Evo platform and the MQB platform. MQB platform is a transverse front drive platform, it will generally use the front McPherson independent suspension + rear multi-link independent suspension chassis structure, and the MLB Evo platform is a longitudinal front drive platform, it will generally use the front multi-link independent suspension + rear multi-link independent suspension chassis structure. McPherson independent suspension structure is simple, low cost, widely used in SUVs below 300,000 yuan, while multi-link independent suspension (a variant of the double wishbone) structure is complex, high cost, widely used in SUVs above 300,000 yuan, its dynamic performance is more stable, especially the suppression of roll is more outstanding, which is a difference.
The second difference is the engine layout, MLB Evo platform engine longitudinal, gearbox longitudinal, the center of gravity to the middle of the body tilt, counterweight is more uniform, the handling texture is more excellent, and the MQB platform engine is transverse, the gearbox is transverse, the center of gravity is tilted to the front of the body, there is a "top-heavy" phenomenon in the layout, there is also a "nod" phenomenon when braking sharply, the control texture is greatly affected, and the dynamic performance of the body is not as good as the model created by the longitudinal platform.
The third difference is the different gearboxes, the medium and large SUVs created by the MLB Evo platform are matched with the 8AT gearbox, while the models created by the MQB platform are matched with the 7-speed dual-clutch transmission (Note: The medium-sized SUV created by the MLB Evo platform matches the 7-speed wet dual-clutch transmission). So, what's the difference between 8AT and 7DSG? ZF's 8AT transmission pays more attention to ride and stability, while the 7DSG transmission pays more attention to fuel economy, it is faster to change gears, high transmission efficiency, theoretically more fuel-efficient, but it does not have a torque converter (the 8AT transmission is connected to the engine through a torque converter), and the role of the torque converter is to buffer the speed regulation, in low-speed congested road conditions, the shift experience is more smooth, the 7DSG transmission is connected to the gearbox through two clutches, and one clutch is responsible for odd gears (such as 1, 3, 5). , 7 gears), a clutch is responsible for even gears (such as 2, 4, 6 gears), two sets of gear shift mechanisms will inevitably improve the efficiency of shifting, but there is no hydraulic torque converter buffer speed regulation, in low-speed congestion road conditions will inevitably produce frustration.
The fourth difference is that the four-wheel drive system is different. MQB platform to create the model equipped with 4MOTION four-wheel drive system, it is provided by BorgWarner the fifth generation of Henderson Haldex full-time four-wheel drive system, the structure itself and other horizontal platform to create SUVs are no different, are through a set of electronic control multi-plate clutch type limited slip differential to distribute inter-axle power, between the wheels is controlled by electronic limit slip, but because the multi-plate clutch can not be completely separated, so the rear axle always maintains at least 5% of the power, although it is a full-time four-wheel drive system, can get rid of the general ability. The four-wheel drive system based on the MLB Evo platform is also called the 4MOTION full-time four-wheel drive system, but it uses the Towson C type central differential, four wheels with EDL electronic limited slip, the rear axle is an open differential, the structure is consistent with the Audi Q7 and other MLB Evo platform to create a medium and large SUV, although it is not called "quattro", but in fact, it is the Audi quattro set of things, but the name to follow its own naming rules. As for the ability to get out of trouble, there is no need to worry about this, and you can even drive it for intensity off-roading.
