The sixth generation of the BMW 3 Series Sedan, one of the best selling premium car in the world has been unveiled. The 320d EfficientDynamics Edition will be the most fuel efficient version with an engine output of 163 hp uses only 4.1 liters/100 kilometers in the EU test cycle, with CO2 emissions of 109 g/km.
Here are the technical details and powerplant differences between the new and the old model.
Technical news and details – 2012 BMW 3 Series F30
A new engine will replace the six-cylinder 3.0-litre engines in the previous 325i and 330i. This new four-cylinder 2.0-litre petrol unit, develops 245hp and 350Nm of torque, in the F30 328i. It features High-Precision Direct Injection, BMW’s new TwinScroll turbocharging, Double-VANOS variable camshaft timing and VALVETRONIC variable valve opening technology.
The ActiveHybrid 3 will arrive at roughly the same time, and will use the powertrain recently announced for the ActiveHybrid 5. This pairs the 335i’s 306hp six-cylinder engine with an up to 40kW electric motor in a particularly intelligent and efficient way.
Drive Performance Control (Standard) – Dynamic Performance Control switches power between the left and right rear wheels to stabilize the vehicle within milliseconds and help increase traction and lateral acceleration. Handling is lighter and more precise during normal as well as difficult driving conditions.
Dynamic Performance Control increases directional stability when accelerating out of bends and provides the driver with extra support when dealing with difficult driving conditions. Before under- or oversteer can take place, lateral guided force is used to keep the vehicle on track.
In the new 3 series, the system allows the driver to swap between up to four driving modes, varying from sporty to extremely economical. The four modes are ECO PRO, Comfort, Sport, and Sport + (Sport + is included only on Sport models or with selected optional equipment).
Auto Stop-Start (Standard) plus Brake Energy Regeneration – Auto Stop-Start is fitted to all versions, manual and automatic, along with Brake Energy Regeneration, on-demand control of engine ancillary components and tyres with less rolling resistance.
Servotronic speed-sensitive (standard) on 328i and 335i derivatives and optional on all others.
Eight-speed automatic gearbox (optional) Available for every engine ( actual models )
Tire Puncture Warning System (TPWS) - a system that regularly monitors the tire pressures of all four tires by comparing their rotational speed when the vehicle is being driven.
Adaptive M Sport suspension (optional) – A ten-millimeter lower suspension lowers the center of gravity for faster cornering. Sensors measure relevant acceleration and automatically adjust the damping within hundredths of a second while Driving Dynamic Control allows you to choose between the modes Normal, Sport and Sport+.
M Sport brake (optional) –
Dynamic Safety (optional) – active from 18 km/h – tensions the seat belts and closes any open windows or the sunroof (if fitted and open) if an accident seems imminent
M Sport Brake (optional) – Aluminium four-piston fixed callipers at the front and two-piston fixed callipers at the rear, and large brake discs, combine extremely low weight with very short stopping distances.
BMW ConnectedDrive (optional) – offers BMW Parking Assistant, Surround View, Active Cruise Control with Stop&Go function, and Speed Limit Info with No Passing Info display. They are joined in the new BMW 3 Series Sedan by features which further increase levels of passenger comfort – such as Real-Time Traffic Information (RTTI), information and office services, and travel and leisure planners using the Google Maps and Panoramio services.
Lane Change Warning System (optional) – warns BMW 3 Series Sedan drivers of the potential danger of such an overtaking manoeuvre. The system uses a pair of rear-mounted radar sensors to monitor traffic in the adjacent lanes, from the blind spot to a distance of approximately 60 metres (200 ft.) behind the car.
Lane Departure Warning System and Collision Warning (optional) – activated at speeds above 70 km/h (43 mph) warns the driver if he unintentionally strays out of his lane.
BMW Assist Emergency Call with automatic vehicle location (optional) – allows the emergency services to receive detailed information on the type of collision and likely injuries before arriving at the scene of the accident.
High-Beam Assistant (optional) – automatically switches high beam on and off, as conditions require, ensuring that the driver always has optimal visibility without having to switch manually
Speed Limit Info with No Passing Info display and Speed Limit Device – alert drivers to the current speed limit on the road on which they are travelling. This information is checked against the navigation system’s database of speed limits. As with speed limits, if the system detects an overtaking restriction, a symbol of a road sign is displayed in the instrument cluster or optional Head-Up Display until this restriction changes or no longer applies.
– Rear view camera and Surround View deliver a perfect overview
– Active Cruise Control with Stop & Go function
– BMW Parking Assistant

Dimensions and weight
– Weight: 50 kg less compared to the old model
– a longer wheelbase (now 2,810mm, an increase of 50mm on the previous model)
– wider tracks (by 37mm at the front and 47mm at the rear)
– overall length: 93mm more
– 50mm longer wheelbase

Drag coefficient (Cd): down to as low as 0.26 thanks to optimized aerodynamics. The new 3 Series Saloon features a streamlined underside, covers which create a diffuser effect at the rear and Aero Curtain air channels in the front apron which reduce the turbulence created by the revolution of the front wheels in their arches.
