I loved driving the BMW 325 in my youth, especially the E46 model from that era, which featured a six-cylinder engine. The startup sound was deep and powerful, with excellent high-speed stability and smoothness like silk. Nowadays, the new 325 models have switched to four-cylinder turbocharged engines, offering more tech but less classic charm. The change in cylinder count reflects the trends of the times: six-cylinders are fuel-thirsty but full of nostalgia, while four-cylinders are economical and eco-friendly. If you're considering a used BMW, check the production year—early 2000s 325s are mostly six-cylinder fun machines, easier to maintain with lower carbon buildup risks. Either way, the 325 delivers top-tier driving dynamics, with an engine layout designed for perfect balance.
The newly purchased BMW 325 comes with a four-cylinder engine paired with a turbocharger, delivering impressive performance. It offers ample power for daily use, with quick acceleration and effortless overtaking, while maintaining fuel consumption at around 8L/100km, making it economical for city driving. The reduced number of cylinders simplifies maintenance, with only four spark plugs and ignition coils, significantly lowering upkeep costs. In terms of noise, while it lacks a roaring start, the cabin remains quiet, ensuring comfort on long trips. Compared to the older six-cylinder models, it feels slightly less smooth, but modern tuning has narrowed the gap, resulting in high overall efficiency. Fellow car enthusiasts often discuss the new 325's great tuning potential—minor modifications can easily enhance its power, making it very enjoyable to drive.
The BMW 325 engine is now mostly a four-cylinder, known for its simplicity, reliability, and low failure rate. The number of cylinders affects power output: the four-cylinder design is lightweight, sufficient for city driving, and offers good fuel economy. Historically, there were six-cylinder versions like the E90 series, but newer models have all switched to four-cylinders. Maintenance tips: change the oil regularly to avoid carbon buildup issues, and inspect the spark plugs every 50,000 kilometers. Overall, the build quality is excellent, with quick acceleration response and quiet operation when parked.
