Audi A4 B6The second generation debuted in 2000. The serial release began since 2001. It was based on the new Volkswagen B6 platform. The second generation began to be issued also in a body like cabriolet (Cabriolet). The design was executed in style of the second generation Audi A6. On this generation the new multitronic transmission debuted. It added Tiptronic on front-wheel models. The only problem was the fact that it could not be installed on cars with the moment of more than 310 N · To m.
Audi body a4 became more spacious than the second generation, in comparison with the predecessor: on length on 69 mm (4547 mm), on width on 33 mm (1766 mm), and on height on 13 mm.
The car was equipped with a totality of security aids. The basis of safety of passengers is made strong section of salon with certain characteristics of deformation, a safety cushion of the driver and forward passenger, and also by side head safety cushions of Sideguard and the mechanism of a tension of a belt for front seats. The electronic antistrange system of stabilization of course stability, and also the amplifier of emergency brake application is serially installed.
The body of the car is galvanized completely, the producer gives a 10-year guarantee for lack of corrosion. The body represents the bearing steel structure with the built-in aluminum components that considerably loses car weight.
Petrol engines - line four-cylinder, V-shaped six-cylinder (eight-cylinder on the S4 models) with electronic control. Diesel engines - line four-cylinder, V-shaped six-cylinder.
All engines of the Audi A4 with liquid cooling, are located is longitudinal.
Models with forward or the Quattro four-wheel drive are produced. On all-wheel drive models the interaxal differential of "Torsen" with automatic blocking is established.
Running gear from aluminum alloy that in turn provides high dynamic characteristics and accuracy of driving.
Depending on a complete set either 6-staged RKPP, or AT is established completely synchronized 5-(Tiptronic with the dynamic program of switching of DSP or Multitronic with the dynamic program of regulation of DPR).
Forward suspension bracket – independent, four-lever. The depreciation racks consisting of cylindrical screw springs, shock-absorbers in the form of a double pipe and the top support of the big size. The stabilizer does not participate in the direction of wheels, and through connecting bars is connected with depreciation racks. The beam of the bridge fastens to a body on rubber-metal support.
The suspension bracket of back wheels is equipped with trapezoidal levers. The beam of a suspension bracket is made of steel, trapezoidal levers - from the hollow aluminum shape. Such design is characterized by the insignificant weight and compactness. Thanks to it becomes possible to reach both at front-wheel option, and at the four-wheel drive of a low arrangement of a floor in a luggage carrier and the optimum width of a cargo compartment.
All lever elements through rubber-metal support are connected by hinges to elastically established suspension bracket beam that provides effective clearing of vibrations of a body. Podressorivany a back suspension bracket it is carried out by screw springs and two shock-absorbers which are located separately and easily act.
The steering mechanism – rack, with coefficient of strengthening of the hydraulic booster (Servotronic), dependent on speed. Adjustable, safety steering column.
The car is equipped with the electronic antistrange system (stability stabilization - ESP) uniting system of anti-blocking of brakes (ABS), the traction control system (ASR), electronic blocking of differential (EDS) and the distributor of brake efforts (EBV) in uniform network. The amplifier of emergency brake application (BAS) is installed.
The basic brake system – hydraulic, double-circuit with diagonal division and the dual amplifier. System of anti-blocking of brakes (ABS) with electronic distribution of brake forces (EBV) with the vacuum amplifier.
Brake mechanisms - disk, ventilated on forward wheels.
The uniform lock with direct or remote control is used to locking of locks.
The closest term of approach of planned maintenance is displayed by the indicator on the display.
The information system of the driver is installed as the standard equipment.
Magnificent aerodynamics and use of light materials promoted decrease in fuel consumption. Thanks to high-strength steel and additional protective elements, and also development of big zones of deformation, ensures still big safety, than the previous model.
In total during production 718219 sedans and 482633 versatile persons were made
