In this Management the BMW models of the 5th series with ryadny six-cylinder petrol engines (DOHC) 2.0, 2.3 and 2.8 of l, release from 12/95 g and the turbodiesel engine (SOHC) of 2.5 l are considered, release from 3/96 g the chosen data (technical characteristics, adjusting data, schemes of electric equipment, procedure of service and operation questions) on models with V-shaped 8-cylinder engines 3.5 and 4.4 of l Besides, are presented.
The independent aluminum forward suspension bracket is executed on double levers with a beam connected with a body through rubber support, Mac-Fersona racks, screw springs and gas-filled shock-absorbers. The forward beam via cross-section levers and drafts is connected with rotary support. The hydraulic opiraniye of cross-section levers provides compensation of fluctuations even at not balanced wheels. The stabilizer of cross-section stability is established.
The multilever aluminum back suspension bracket with a stretcher provides a double elastic suspension bracket of the main transfer. Four cross-section levers are elastically connected with a stretcher. The stretcher is also elastically connected with a body.
The brake system consists of disk mechanisms on all wheels. Additional drums of the parking brake are established on back wheels. The brake amplifier is applied on cars with the petrol engine. The hydrosystem is divided into two contours - one contour of the forward brakes, the second - back. Distribution of effort of braking is carried out by anti-blocking system (ABS). The system of automatic stabilization of the stability, added with a regulator of traction effort of the engine (ASC+T), provides the maximum stability of the car on the road.
For driving the steering gear реечного type with the hydraulic booster which factor of strengthening depends on number of turns of the engine serves. On some models the Servotronic hydraulic booster which factor of strengthening depends on speed of movement is established. The safety cushion of the driver is located in a steering wheel.
In the car it can be established 5-or a 6-step manual box of gear shifting (RKPP), or 4-or 5-step automatic transmission with adaptive system of electronic and hydraulic management (AGS). The Steptronic system, allowing to choose transfer manually, is established on some models.
Arc xenon headlights provide fine visibility of a road cloth.
