The quintessential sports sedan is back - and better than ever. With a powerful 255 hp engine featuring Valvetronic technology, a 5-link/5-beam rear suspension, and increased passenger room, performance and luxury are perfectly blended in a more powerful, more agile sedan offering more safety and comfort features than ever before. Advanced Dynamic Stability Control (DSC) and optional Active Steering help keep the driver in total control, while premium interior materials like leather, Poplar Natural wood trim or brushed Aluminum, create an alluring atmosphere to satisfy their senses. Double Vanos
Double VANOS allows the engine to 'steplessly' choose valve timing for both intake and exhaust camshafts. Electronically controlled in response to engine speed, load and temperature, Double VANOS maximizes engine response, efficiency and emission control. The benefit: more low- to medium-speed torque for strong acceleration and added flexibility for better highway performance, plus quieter, smoother engine at idle.
STEPTRONIC automatic transmission provides a choice of three modes: 'Drive', which incorporates BMW's Adaptive Transmission Control; 'Sport' automatic, for a more dynamic shift pattern; and STEPTRONIC automatic, for the hands-on control of a manual without using a clutch.
Check Control helps the driver to be aware of the operational readiness of important functions, such as the lighting system and fluid levels. A pictogram display indicates the location of the feature that requires attention. Warnings are shown in the Check Control display at the bottom of the main instrument cluster, and are prioritized according to urgency. On-board computer functions can also be shown in the Check Control display, if desired. Climate Zone Ventilation
Electronic climate zone controls allow the driver to select a lower air temperature for around the head and chest than in the footwell. With automatic recirculation control, when a sensor detects certain pollutants in the air, such as carbon monoxide or ethanols, it automatically switches to recirculating air. Twin active-charcoal micro-filters significantly help reduce air pollutants, such as dust and bacteria, and odors, from entering the cabin.

Dynamic Stability Control
Dynamic Stability Control is an innovative technology that combines the functions of traction control, braking enhancement, and cornering stabilization. DSC sensors continually monitor cornering-steering angle, transverse acceleration, yaw, wheel speed and brake pressure to instantly detect and correct loss of wheel traction due to slick spots, nasty weather, or emergency maneuvers. DSC helps you stay in control under all conditions, in any situation.
BMW's Head Protection System is an inflatable tubular structure to protect the heads of a vehicle's front and rear seat occupants. Operating in conjunction with the side airbags, the system provides front seat occupants with outstanding protection in the case of severe side impact. It helps protect the head from hitting the side window and being hit by objects penetrating the side window. In recognition of this remarkable protection, BMW was named 'Safe Car of the Millennium' by the International Brain Injury Association. Inline Six-Cylinder Engine
The BMW inline six-cylinder engine has long been recognized as one of the very few truly superb powerplants of the automotive industry. And the new 3.0-liter, 24-valve version of the celebrated BMW inline six-cylinder engine continues this tradition, offering even greater power, refinement, response, and efficiency.
This new engine features a number of pioneering technologies, including Valvetronic and an electronically controlled water pump that uses less power than conventional pumps, which contributes to the engine's increased power output. And the new engine block, made of an advanced, lightweight composite magnesium/aluminum, increases the engine's overall power-to-weight ratio.
In the 325i, the new inline six-cylinder engine produces 215 hp, and propels the new 3 from 0-60 in a swift 6.7 seconds.* A three-stage induction system, different exhaust, and powertrain software results in a 255 hp output from this same engine in the 330i, which launches the car from 0-60 in a mere 6.1 seconds.Logic7 Audio System
Exceptional audio potential is fully reached with the available Logic7 audio system, which creates a new standard for acoustic realism in mobile sound. Únlike traditional stereo systems, Logic7 routes two-channel (stereo) sound through a seven-channel playback matrix to create 360-degree Surround Sound. The result is a thrilling recreation of the original music recording. Digital Sound Processing (DSP) and 13 upgraded speakers combine to deliver remarkable clarity and sound separation to all seating positions. And with the standard auxiliary audio input or optional 6-disc changer, the concert in the car can last for hours on end. Run-Flat Tires
No more roadside tire emergencies. These self-supporting tires with integrated reinforcements allow tires that have experienced a loss of air pressure to maintain their shape and full use. They can be driven for up to 150 miles at reduced speeds.
*BMW AG test results. Actual acceleration results may vary depending on specification of vehicle; road and environmental conditions testing procedures and driving style. These results should be used for comparison only, and verification should not be attempted on public roads. BMW urges you to obey all posted speed limits and to please wear your safety belt at all times. Service Interval Indicator
Recognizing that each vehicle is used differently - and so the need for routine maintenance is different for each vehicle - BMW developed the Service Interval Indicator. This device continually analyzes the way the BMW is driven, and uses this analysis to determine when it needs servicing - not just based on miles driven. The basic Oil Service includes a change of engine oil and filter, and select other maintenance items. Long-life sparkplugs are designed for a service life of 100,000 miles.Source - BMW
