The new model range of BMW of the 3rd series of the fourth generation, the factory designation “Е46”, appeared in April, 1998. This new Sedan on level of the used technological development, comfort and controllability level closely came nearer to more high-class cars. ABS enters into standard equipment, the antiprobuksovochny system, two safety cushions, a natyazhitel and the clamp of a seat belt established ahead head safety cushions, electric drives of window regulators and a radio tape recorder.

Cars can be completed with any of six engines, beginning from economic 4-cylinder for the Sedan 316i (the maximum speed of 200 km/h), same 1.8-liter and finishing 6-cylinder 2.0, 2.3 and 2.8-liter, with system of a gazoraspredeleniye of Vanos, and 5-step RKPP or AT.
All engines have a longitudinal arrangement in an impellent compartment and actuate back wheels.

There was a model 320d (turbodiesel) which is dispersing to 100 km/h for 9.9 pages later. Thanks to increased by 60 mm to a track and on 30 mm to the wheel Sedan base it is very steady, however it caused suspension bracket modernization. The salon which equip with six auxiliary safety cushions is updated also.

One year debuted two-door Compartments of 323 Ci and 328 Ci later. Designers managed to facilitate visually initially enough massive body, having kept "thin" averages of a rack. Glasses of doors are issued on American manners - without a framework. Back lateral glasses do not fall, and turn only a little. Back seats for increase in space of a luggage carrier can be combined, the steering wheel and the check point lever are fitted by skin. Top of a model range of the 3rd series - the M3 Compartment with the engine of 342 hp.

At the end of 1999 after the Sedan, the Versatile person and the Compartment of the third series the concern prepared a cabriolet for production. "Three" with soft top is made on the basis of the Compartment, however doors, back wings and the back panel of a body found other plasticity - the cabriolet looks prompter, dynamic. The collapsible top is cleaned in the special container, and at desire (for example, during the winter period) this container it is possible to remove and establish easily a rigid roof which is offered at additional expense.

The increased intervals of maintenance allow to cut operational costs. For example, the interval of replacement of oil can make depending on a mode of use of the car to 30 000 km.

Various electronic systems increase comfort of passengers. Memory of individual settings of the equipment and a key belong to such systems, for example. By means of the first the owner of the car establishes the main functions of setup of the uniform lock, internal and external lighting, and also the conditioner. Memory of a key allows to keep settings of four drivers of the car having an own key. Thanks to it automatic control of provision of a seat when opening the uniform lock is possible. Besides, the uniform lock can be programmed in such a manner that doors, after a troganiye from a place, are automatically blocked.

There is a wide choice and other systems of comfort established as the additional equipment: the xenon lamps, automatically blacked out rear-view mirror, the conditioner, continuous control of pressure of air in tires, a screen wiper with the rain sensor, navigation system and the TV.
The conditioner enters into a standard complete set of 6-cylinder models.

Traffic safety raises thanks to ABS existence. At sharp braking on turns the monitoring system improves controllability and stability of the car. As special addition there is a system of dynamic stabilization of stability of DSC which reacts for the beginning of emergence of drift of the car and counteracts it by means of a pritormazhivaniye of certain wheels.

On models with a full drive (325xi, 330xi, 330xd) the rotating moment of wheels is distributed between lobbies and back wheels in a constant proportion of 38 % and 62 % by means of interaxal differential and system of automatic differential braking of ADB.
