Cars Audi A4/S4 - the summary
A4 The second generation has appeared in the market in November, 2000 performed by the Sedan. Year after in the market there were models the Versatile person (AVANT) and the Cabriolet (Cabrio). The sports variant has been presented in 2002.
Body A4 of the second generation has increased 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.
A4 It is equipped by a totality of means of safety. A basis of safety of passengers is the strong section of salon with certain characteristics of deformation. To safety means pillows of safety of the driver and the forward passenger, and also lateral head pillows of safety Sideguard and devices of a tension of a belt for forward seats belong also. The system (stabilisation of course stability), and also the amplifier of emergency braking is serially established electronic противозаносная.
Completely zinced body, with a 10-year-old guarantee on absence of corrosion, represents bearing steel design with the built in aluminium components providing weight reduction of the car. As materials, for additional weight reduction of the car, high-strength steel sheets, plastic and magnesium are applied.Petrol engines - line четырёхцилиндровые or V-shaped six-cylinder (eight-cylinder on models S4) with electronic control.
Diesel engines - line четырёхцилиндровые or V-shaped six-cylinder.
All engines with water cooling and an arrangement in an impellent compartment along the car.
Models with a forward or full drive Quattro are issued. On all-wheel drive models the interaxal differential Torsen with automatic blocking is established.
The modified running gear from an aluminium alloy provides high dynamic characteristics and accuracy of driving.
Depending on a complete set it is established completely synchronised 5 or 6-step Manual transmission, or АТ (Tiptronic with the dynamic program of switching DSP or Multitronic with the dynamic program of regulation DPR).
Forward suspension bracket – independent, четырёхрычажная McPherson with screw springs, telescopic gasи shock-absorbers and a tubular bar of the stabilizer. The bridge beam fastens to a body on rezino-metal support.
Independent suspension bracket of back wheels with screw springs and gasи shock-absorbers. The bridge beam fastens to a body on rezino-metal support.
The steering mechanism – реечный, with factor of strengthening of the hydraulic booster dependent on speed (Servotronic). An adjustable, safety steering column.
The car is equipped electronic противозаносной by system (stability stabilisation - ESP), antiblocking of brakes uniting system (ABS), антипробуксовочную system (ASR), electronic blocking of differential (EDS) and the distributor of brake efforts (EBV) in a uniform network. The amplifier of emergency braking (BAS) is established.
Base brake system – hydraulic, two-planimetric with diagonal division and the dual amplifier. System of antiblocking of brakes (ABS) with electronic distribution of brake forces (EBV) with the vacuum amplifier.
Brake mechanisms - disk, ventilated on forward wheels.
The uniform lock is applied to lock-out of locks with direct or remote control.
The nearest term of approach of planned maintenance service is displayed by the indicator on the display.
The information system of the driver is established as the standard equipment.
Magnificent aerodynamics and application of easy materials promoted decrease in the expense of fuel. Thanks to a high-strength steel and additional protective elements, and also working out of the big zones of deformation, the previous model provides still the big safety, than.
