How about Audi a4 four-wheel drive?

A4 is actually a high-end sports car using Volkswagen Passat. As a B-class car, it has a short body and high flexibility and strength. Very suitable for driving on mountain roads and gravel roads. A4 front drive and four-wheel drive, for B-class cars, the front drive will make the control too conservative and the rear drive area too flexible. It is recommended to buy the domestic 1.8T four-wheel drive version, which consumes a little more fuel than Passat. Overall, it is a very good car! The brand-new domestic Audi A4 was officially launched on June 25th, 2005, 10. It is a modified version of the old A4, and its appearance is consistent with the latest A4 abroad. In terms of body design, the new Audi A4 inherits the family characteristics of the new generation of Audi products-integrated single-frame air intake grille. This iconic design has become a feature of all Audi cars. The V-shaped lines extending downward from the hood are organically combined with the bumper of the same color. The redesigned headlights form a tough broken line under the lamp frame, giving people a more impactful visual effect. Bi-xenon headlights make the vehicle better at night and improve the safety of driving at night. The overall design of the front of the car makes the new Audi A4 look dynamic and elegant. The taillights of the new a4 also adopt a brand-new design, which gradually shrinks from the outside to the inside, echoing the body lines and headlights. Compared with the previous generation, the taillight of the new Audi a4 has a larger lighting area, which can provide more obvious lighting effect when the vehicle is driving. The new Audi A4 * * has seven body colors for consumers to choose from, namely ebony black, bright silver, polar white, Atlas gray, Mauritius blue, Triumph gold and dazzling red. The new a4 engine has three displacements, 1.8t and 3.0 are the same as those of the old cars, and 2.0tfsi is the latest technology engine of Audi. The tfsi turbocharged gasoline direct injection engine equipped with the new Audi a4 2.0t is at a high level in the world automobile engine technology. Fsi fuel direct injection technology is an innovative technology in the field of direct injection gasoline engines. In design, fsi technology is different from other traditional engines in that, contrary to the principle of manifold injection, fsi engine is equipped with fuel supply controlled on demand, four valves per cylinder, variable intake manifold and continuously adjustable intake and exhaust camshafts. Gasoline is directly injected into the combustion chamber, and the common rail high-pressure injection system of single-piston high-pressure pump is responsible for providing accurate fuel for the system, forming a working pressure between 30- 100 bar. At the same time, the geometric design of the fuel chamber and the millisecond accurate calculation of the function of injecting gasoline greatly improve its compression ratio, which is also a necessary prerequisite for efficient new engines. In terms of air intake, fsi engine adopts continuously variable intake manifold, and the required air flow is controlled by electronic system, which realizes throttle-free deterioration adjustment and improves charging efficiency, thus obtaining higher power and making the engine's dynamic response more direct. Fsi engine not only provides greater output power and torque, but also further improves fuel economy and reduces emissions. Compared with the traditional engine, the fuel consumption of fsi engine with the same displacement is significantly reduced. The engine of the new Audi a4 2.0t has been adjusted according to the fuel quality in China, and the exhaust gas has reached the European No.4 emission standard (eu 4). The computer control program of tfsi engine on the new Audi a4 2.0t has been upgraded, and the compression ratio and supercharging have become larger. With the cooperation of turbocharging system, its power reaches 147 kW /200 HP, and the maximum torque output is 280 N? ; M, and when the engine speed is 1800 rpm, it will be completely released until 5000 rpm. The acceleration time of the new Audi a4 2.0t 0 to 100 km/h is 7.5 seconds, with a good sense of movement. Multitronic stepless/manual integrated gearbox The new Audi a4 has three gearbox configuration options: Multitronic stepless/manual integrated gearbox is standard, tiptronic manual/automatic integrated gearbox and manual gearbox. The previous generation domestic Audi a4 was equipped with manual mode 6-speed variable stepless/manual integrated gearbox, and the new Audi a4 was equipped with a new generation 7-speed variable stepless/manual integrated gearbox, becoming the first high-end B-class car equipped with this gearbox in China. Its biggest feature is to upgrade the manual shift mode of the gearbox to level 7, which not only further improves the smoothness and comfort of shifting, but also enables the vehicle to obtain higher power and fuel economy when driving in manual shift mode. As traditional automobile driving technologies, front drive and rear drive have their own advantages and disadvantages. When cornering quickly, it is easy to "push the head" before driving and "flick the tail" after driving. The advantage of Audi quattro full-time four-wheel drive technology lies not only in that the engine power is evenly distributed to the four wheels during normal operation, which provides greater lateral adhesion for the vehicle on the road, but also that the ideal power distribution of each wheel can be automatically realized like lightning when the vehicle turns quickly or encounters complex roads, thus effectively ensuring the cornering stability of the vehicle and its excellent straight-line driving performance on wet/dry roads. Gravel, snow, wet and frozen roads can best reflect quattro's grip advantage. Newly-designed dynamic suspension chassis system The chassis system of the new Audi a4 adopts the newly-designed dynamic suspension chassis system, incorporating the designs and devices of the Audi s4 and the new Audi a6l. The damping springs of the chassis system of power suspension are rearranged according to the load, and the stiffness is strengthened, which makes the suspension system more sensitive to the height change of the car body. The rear trapezoidal connecting rod, wheel carrier, front tie rod and other parts are all from Audi s4. The dynamic suspension settings of the four-link front suspension and the independent trapezoidal link rear suspension have been thoroughly improved, and the spring and damping have been strengthened compared with the previous generation models. At the same time, the research and development personnel of FAW-Volkswagen adjusted the chassis system of the new Audi a4 according to the domestic road conditions, which greatly improved the sports performance of the new Audi a4 on the one hand and the driving comfort of the vehicle on the other. Safe, rich and complete active safety configuration enhances the active safety of the new Audi a4. The highest version of Bosch esp 8.0 electronic stability program comes standard on the new a4, including a series of electronic devices such as anti-lock braking system (abs) with electronic braking force distribution device (ebd), electronic braking force assist system (eba), electronic differential system (eds), drive acceleration slip adjustment (asr) and parking alarm system. Among domestic high-end B-class cars, the new Audi a4 is equipped with the first two full-size airbags for the first time. Two airbags can provide protection for the front passengers according to the severity of the accident, loop unrolling. The front and rear airbags installed on the seat back, as well as the head airbag system, will cooperate with the seat belt tension identification system to provide front and side safety protection for drivers and passengers. Body size Compared with the previous generation Audi a4, the body size of the new Audi a4 has increased, thus bringing more trunk space. The volume of 460 liters can probably meet the basic equipment for people's daily work and weekend travel. Generally speaking, Audi's new a4 is an improvement on the old a4. The biggest change is the shape, 2.0t engine and a new generation of multitronic automatic manual stepless gearbox. Price: 274,900-343,400 yuan
