The interior has been enhanced by means of specific modifications in the selection of materials and surface design. The operating system of the optional BMW iDrive has been revised for the activation and control of entertainment, information, navigation and telecommunications functions. The new generation iDrive is available in conjunction with the optional "Professional" navigation system. What's more, the new iDrive supports multi-mode operation by voice entry.
With the new iDrive, four direct selection buttons grouped around the Controller make it easier to switch between CD, radio, telephone and navigation functions. The functional bookmarks are supplemented with three control buttons.
The new iDrive is presented with a 8.8" Control Display. With its high image resolution, it offers significant improvement in the display of detailed graphics. The structure of the user menu also makes it easier to locate desired functions. All functions controllable by iDrive are listed in the starter menu.
The features of the navigation system "Professional" include a hard drive integrated in the vehicle. The storage medium, with a capacity of 80GB, provides outstandingly fast access to digital maps for navigation and can also be used for an extensive collection of music files. The system enables music files to be transferred to the hard drive from a CD, MP3 player or USB stick.
BMW ConnectedDrive makes BMW the first manufacturer in the world to enable unlimited use of the internet inside the vehicle when stationary. Internet access is available for the new 3-Series as a special equipment option at attractive flat-rate. The transfer of data is based on EDGE technology (Enhanced Data Rates for GSM Evolution) which, unlike UMTS, offers full geographical coverage and is three to four times faster than the mobile phone standard GPRS. The basis for internet use in the vehicle is provided by the further developed functions of iDrive. By pushing the Controller in different directions, the mouse can be moved across the web page displayed on the Control Display.
The safety concept of the new 3-Series is based on a solid body structure, the selective application of high-strength steel types and special deformation elements which divert and absorb impact energy. In addition, there are six airbags, three-point belts and headrests on all seats to offer occupants optimum protection. What is more, ISOFIX children's seat mounts on the rear seats are a standard feature.
As a dynamic concept, BMW ConnectedDrive offers BMW Assist, BMW Online, BMW TeleServices and BMW Tracking, depending on the country in question. At the same time, BMW ConnectedDrive is designed for the ongoing further development of services to increase mobility and information convenience. The Enhanced Emergency Call with automatic positioning and remote control functions are examples of safety-related options which are already available, extending the lead of BMW ConnectedDrive over the competition.
With its optimized engine range, the new 3-Series further extends its leading position in the segment in terms of driving dynamics and economy. With all engine types, both the Sedan and Touring model boast superior fuel consumption and exhaust emission levels than those of their competitors of comparable output.
What's more, a wide spectrum of efficiency measures has been applied within the engine environment to further reduce fuel consumption and exhaust emissions. This includes Brake Energy Regeneration, Auto Start/Stop Function, Shift Point Display, the needs-oriented control of auxiliary units, electro-mechanical power steering, tires with reduced rolling resistance and Automatic Air Intake Flaps. With the comprehensive application of these technologies in what is the most successful BMW model series in terms of sales figures, the development strategy BMW EfficientDynamics achieves an especially broad impact.
As one of a number of features unique within the competitive field, all gasoline engines are fitted with High Precision Injection and all diesel engines combine an all-aluminium crankcase, turbocharging and common rail direct injection of the third generation. The BMW 335i is especially dynamic, accelerating in just 5.6sec from zero to 62mph.
The new BMW 3-Series has the most sophisticated chassis technology in its segment. The five-link rear axle is adapted to the needs of the high-power and high-torque engines. The front axle also reflects a unique standard of engineering. The dual-arm tension strut axle with stabilizer is largely made of aluminium.
The standard equipment also includes an electro-mechanical steering system with integrated Servotronic function for speed-related steering support. Active Steering is an option, where steering transmission is adapted to road speed.
