The ideal combination of driving fun and efficiency also characterizes the other engines available for the new BMW 3 Series. Spontaneously responding, high-torque 6-cylinder and 4-cylinder diesel engines, powerful and high-revving 4-cylinder petrol engines and the 6-cylinder in-line petrol engine well-known for its unique refinement and dynamic power delivery form a portfolio which is unequalled in the segment of the BMW 3 Series. With five petrol engines and five diesel engines, the new BMW 3 Series offers the most extensive range in its segment. When it comes to both petrol and diesel power units, customers have the choice of four 4-cylinder and three 6-cylinder engines. The output range extends from 105 kW/143 bhp in the 4-cylinder models BMW 318i and BMW 318d to a 225 kW/306 bhp in-line 6-cylinder engine in the BMW 335i. All engines are available for both the BMW 3 Series Saloon and the Touring model, and all are combined with the latest BMW EfficientDynamics measures in the environment of the engine, as suits the specific model configuration. Each of the ten engine types thus has a more favourable relationship between driving dynamics and economy as compared to competitor vehicles of similar output.
As one of a number of features which are unique within the competitive field, all petrol engines are fitted with High Precision Injection and all diesel engines combine an all-aluminium crankcase, turbo charging and common rail direct injection of the third generation. The BMW 335i is especially dynamic, accelerating in just 5.6 seconds from zero to 100 km/h. The outright leader in terms of efficiency in the entire vehicle segment is the BMW 318d with an average fuel consumption in the EU test cycle of 4.7 litres per 100 kilometres and a CO2 emission level of 123 grams per kilometre.

The new BMW 3 Series also presents a further expanded selection of engine types for combination with the intelligent all-wheel drive system BMW xDrive. For the first time it is possible to fit 4-cylinder models of this series with xDrive. The new BMW 320d xDrive combines outstanding efficiency with superior properties in terms of driving dynamics and traction. Both for the Saloon and the Touring of the new BMW 3 Series it is now possible to combine three petrol engines and two diesel engines with the intelligent all-wheel drive system BMW xDrive. The models in question now bear the designations BMW 335i xDrive, BMW 330i xDrive, BMW 325i xDrive, BMW 330d xDrive and BMW 320d xDrive.

The electronically controlled permanent all-wheel drive system BMW xDrive offers an incomparable level of comfort, traction and agility over all surfaces due to its flexible distribution of drive torque between the front and rear axles. In order to ensure especially precise control, the computer unit of the drive stability regulation system Dynamic Stability Control (DSC) and that of xDrive are networked with each other in the Integrated Chassis Management (ICM). With these capabilities, xDrive supports driving dynamics because it identifies any tendency to oversteer or understeer early on and counteracts effectively.
