BMW 3 Series
374 hp · 500 Nm
The benchmark of the rear-wheel-drive sports sedan class. In Turkey it sold heavily as the 320i with the 1.6-litre 170 PS engine due to tax brackets. Its road holding and gearbox are very strong; maintenance and parts costs are above the class average.

- Engine code
- B58B30M1
- Engine family
- B58
- Layout
- Inline 6-cylinder, 24-valve, DOHC
- Engine displacement Engine displacement (cc) The total volume of the cylinders. 1.0 = about 1000 cc. Thanks to turbos, small engines can now be as powerful as large ones. In many countries, taxes are calculated based on engine displacement.
- 2,998 cc
- Number of cylinders Number of cylinders 3-cylinder engines are economical but vibrate a little more at idle. 4 cylinders are balanced; 6 cylinders are very smooth and powerful.
- 6
- Turbo Turbo A propeller spun by exhaust gas forces more air into the engine, so a small engine becomes more powerful. In turbo engines, good-quality oil and timely maintenance matter even more.
- Turbo
- Fuel system
- Direct injection (350 bar)
- Timing drive Timing belt or chain? It keeps the engine's internal parts turning in sync. A belt must be replaced at set intervals (usually every 90-120 thousand km); if it snaps, the engine is seriously damaged. A chain usually lasts the life of the engine, but a rattling noise should be checked.
- Timing chain
- System power Engine power (horsepower / PS) Determines how quickly the car can accelerate and its top speed. For city driving, 90-130 hp is enough; if you overtake often on the highway, anything above 150 hp feels comfortable.
- 374 hp @ 5500-6500 rpm
- Torque Torque (Nm) The engine's "pulling force". High torque feels strong at low revs: the car does not struggle on hills, when loaded, or when setting off. You can think of power as how fast you can go, and torque as how easily the car accelerates.
- 500 Nm @ 1900-5000 rpm

- Engine oil Engine oil A value like "0W-20" shows the oil's thickness; but what really matters is the manufacturer approval (e.g. VW 508 00). Using the wrong oil can cause expensive failures, especially in engines with turbos and particulate filters.

- Coolant
- BMW Antifreeze Coolant
- Brake fluid Brake fluid Transfers the force from the brake pedal to the wheels. Over time it absorbs moisture and its boiling point drops, so it should be replaced every 2-3 years regardless of mileage.
- DOT 4 LV · Every 24 months
- Battery Battery types (AGM / EFB) Cars with start-stop systems need durable EFB or AGM batteries. Replacing them with a standard battery will cause it to fail quickly. On some premium brands, the car must be told about a new battery after it is replaced.
