BMW 3 series 2015 vs BMW 4 series 2017
| Gearbox: | Automatic | Manual | |
|---|---|---|---|
| Engine: | 2.0 Diesel | 2.0 Petrol | |
| Diesel (BMW 3 series) engines typically outperform gasoline engines in terms of fuel efficiency and low-end torque. This makes them more economical and better suited for towing or long-distance travel. However, gasoline (BMW 4 series) engines mostly are lighter, quieter, and offer better acceleration and responsiveness, especially in smaller vehicles. For more information, see the article "Diesel or Petrol: Fuel Economy and Key Differences." | |||

Drive type | |||
| Wheel drive type: | 4x4 - AWD (all-wheel-drive) | Rear wheel drive (RWD) | |
|
BMW 3 sērija has 4x4: BMW xDrive is a proactive all-wheel drive system without a center differential that engages before the vehicle becomes destabilized, unnoticed by the driver. Torque is distributed between the axles by an electronically controlled multi-plate clutch in the transfer case. The clutch is partially locked at most times, distributing power to both axles in a 40/60 front/rear ratio, but the system is capable of sending 100% of the torque to either axle. At higher speeds or when parking, multi-plate clutch is disengaged and all power is transferred to the rear wheels. DSC system (Dynamic Stability Control) also brakes the wheels separately to regain traction and assist in cornering. | |||
