When you mate a powerful 255 hp engine featuring Valvetronic technology, and a 5-link/5-beam rear suspension to BMW's xDrive intelligent all-wheel drive system, it's safe to predict nothing less than all-out performance. All year round. And with more comfort and safety features than ever before, like enhanced Dynamic Stability Control (DSC), every road offers ideal driving conditions, every single day. When it's nasty outside, the 330xi's inviting interior, filled with premium materials like leather, Poplar Natural wood trim or brushed Aluminum can be enjoyed all the more. The 330xi. Every drive is a phenomenon. Valvetronic
Valvetronic replaces the function of the throttle butterfly with continuously variable valve lift control, to enable the engine to breathe more easily. An electric motor controlled by the accelerator pedal turns an eccentric shaft, which transmits the rotation of the cams to the valves via a connecting lever. Controlling the position of the eccentric shaft controls the ideal valve lift. The result is remarkably smooth and optimized power and efficiency at all times.
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.
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.
Head Protection System (HPS)
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. 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. 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. Vehicle & Key Memory
Handy Vehicle & Key Memory features can activate special convenience and safety features already programmed in the 3 Series. Vehicle Memory offers the choice of activating/deactivating Daytime Running Lights, an anti-theft motion detector, and 'Pathway Lighting' - headlights that stay on for 40 seconds after turning off the ignition.
With Key Memory, up to three keys can be separately programmed to individual preferences. Choose to unlock just the drivers door or both doors with the first press of the keyhead remote. Key Memory can also be programmed to relock the vehicle automatically when it reaches 5 mph. Key Memory can return the drivers seat to the same position as the last time that key was used; similarly, it can return climate control to the previous setting used.Source - BMW
