The design of the F30 is an evolution of its predecessor, but also leans heavily on the design line of the 5 Series. Thus, the side view was almost completely taken over by the E90. The rear view, however is not very different from that of the 5 Series. Fall on the front especially on the headlamps, which extend to the kidneys frame. The interior is again more driver-oriented as opposed to the E90.

At its debut, the F30 was available in four engines, two petrol and two diesel:

  • 328i, the true novelty of the initial range, equipped with the new N20 engine from 1997 cc, twin-scroll turbocharged engine and capable of delivering up to 245 hp of maximum power;
  • 335i version of the range, equipped with the same engine as the previous 335i, namely the N55 from 2979 cc engine with twin-scroll turbocharger and 306 hp of maximum power;
  • 320d EfficientDynamics, ecological and salvaportafogli version, powered by a 1995 cc engine from N47 turbo diesel with common rail technology and maximum power of 163 hp;
  • 320d, closely related to the version with 163 hp, but more handsome with its 21 hp of maximum power in the most.

The BMW F30 voltage supply consists of:

A – Voltage supply components, front
B – Voltage supply components, rear
1 – Main battery cables
2 – Power distribution box, front
3 – Power distribution box, engine compartment
4 – B+ jump start terminal point
5 – Starter motor
6 – Alternator
7 – Power Distribution Module (PDM)
8 – Safety battery terminal (SBK)
9 – Battery power distribution box
10 – Power distribution box, luggage compartment
11 – Intelligent battery sensor (IBS)
12 – Battery

There is an increasing use of aluminum lines for the voltage supply in the F30. Lower weight and lower costs are the reason for the increased use of aluminum. The B+ under floor cable made of solid aluminum with a flat 59 mm2 profile section runs from B+ transfer terminal point (rear) to the B+ jump start terminal point (front). Connectors with a secondary lock (CPA, Connector Position Assurance) are used at both the engine compartment power distribution box and the luggage compartment power distribution box. This provides for significantly more reliable contacting. Thinner cables wit a cross – section of just 0.22 mm2 are used in the F30.
