Audi A4/S4 cars - the summary
A4 of the second generation appeared in the market in November, 2000 performed by the Sedan. Year late in the market there were models the Versatile person (AVANT) and the Cabriolet (Cabrio). The sports option was presented in 2002.
The body of A4 of the second generation 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 is equipped with a totality of security aids. A basis of safety of passengers is the strong section of salon with certain characteristics of deformation. To security aids safety cushions of the driver and the forward passenger, and also lateral head safety cushions of Sideguard and the device of a tension of a belt for forward seats belong also. The electronic protivozanosny system (stabilization of course stability), and also the amplifier of emergency braking is serially established.
Completely zinced body, with a 10-year guarantee on absence of corrosion, represents bearing steel design with the built-in aluminum 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 - ryadny four-cylinder or V-shaped six-cylinder (eight-cylinder on the S4 models) with electronic control.
Diesel engines - ryadny four-cylinder 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 of "Quattro" are issued. On all-wheel drive models the interaxal differential of "Torsen" with automatic blocking is established.
The modified running gear from an aluminum alloy provides high dynamic characteristics and accuracy of driving.
Depending on a complete set 6-step RKPP, or AT (is established completely synchronized 5-either to 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 McPherson with screw springs, telescopic gas-filled shock-absorbers and a tubular bar of the stabilizer. The beam of the bridge fastens to a body on rezino-metal support.
Independent suspension bracket of back wheels with screw springs and gas-filled shock-absorbers. The beam of the bridge fastens to a body on rezino-metal support.
The steering mechanism – reechny, with factor of strengthening of the hydraulic booster (Servotronic) dependent on speed. Adjustable, safety steering column.
The car is equipped with electronic protivozanosny system (stability stabilization - ESP), anti-blocking of brakes (ABS) uniting system, antiprobuksovochny 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, 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 is applied to locking of locks with direct or remote control.
The closest term of approach of planned maintenance is displayed by the indicator on the display.
Information system of the driver is established as the standard equipment.
Magnificent aerodynamics and application of easy materials promoted decrease in fuel consumption. Thanks to high-strength steel and additional protective elements, and also development of big zones of deformation, the previous model provides still big safety, than.
