BMW 320i has AWD (all wheel drive) (power is automatically distributed between the wheel axles) and manual gearbox with 6 gears. 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.
BMW 320i accelerates to speed 100 kilometres per hour in 7.4 seconds. The maximum speed of this car is 232 km/h.

BMW 320i fuel consumption is 6.8 litres per 100km in combined city/highway mode (14.7 km/l), fuel consumption in city - 8.8 l/100km, highway fuel economy - 5.6 l/100km. Fuel tank capacity is 60 litres or 15.85 gallons, which gives a mileage up to 880 kilometers without refueling in urban cycle and even up to 1060 kilometers on highway.
According to user reviews, this BMW real everyday fuel consumption is 7.9 litres per 100 km, which is 16% more than the manufacturer's stated. More - Real BMW 3 series fuel consumption.

Engine reliability and common problems:

Until 2015, engines used to have problems with the timing chain guides, which have been resolved over time. Other problems with this engine are the oil pump performance and its drive chain, as well as cracking of the oil filter housing.
Overall, this engine can last around 190,000 to 330,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
The engine has hydraulic valve tappets (lifters), which provide quieter operation and do not require periodic adjustment, but are more complex in design and can cause serious engine damage in the event of failure.
Engine displacement 1997 cm3
Number of cylinders 4
Bore (cylinder diameter) 84 mm
Stroke length (piston move) 90.1 mm
Compression ratio 10 : 1
Camshaft drive Timing chain

Chain motors are considered more reliable, chain replacement usually is required less often than a timing belt, but they are often louder and vibrate more.

More service info
Timing chain change interval 100,000 km (recommended)

Sometimes manufacturers do not specify timing chain replacement intervals and design chains for engine life. However, once the recommended change interval has been reached, it is recommended to periodically check the condition of the chain and to change the chain if excessive stretching is detected or if unusual noises from the engine or other symptoms occur.
