What is the horsepower of the BMW 520 engine?

[VanPeyton]

BMW 520 is a model in the BMW 5 Series, featuring a straight-six cylinder engine and an 8-speed automatic transmission, with a maximum power output of 177 horsepower. Introduction to Metric Horsepower: Metric horsepower, also known as PS (Pferdestärke), is a unit of power defined arbitrarily to be very close to the imperial horsepower. One metric horsepower is defined as the power required to lift 75 kilograms one meter in one second. That is: 1 metric horsepower = 75 kgf·m/s = 735 watts. Introduction to Imperial Horsepower: The concept of horsepower as a unit was named by James Watt, the improver of the steam engine, to compare the power of his steam engine to that of a horse. It is defined as "the power required to lift 33,000 pounds one foot in one minute" and is commonly measured in watts (W) or kilowatts (kW).

I remember my friend just picked up the current BMW 520Li last month, which comes with a 2.0T four-cylinder engine producing a maximum of 184 horsepower. Having driven it a few times, the power delivery feels quite smooth—adequate for city overtaking but not overly aggressive. This generation's engine utilizes twin-scroll turbo technology, significantly reducing turbo lag compared to older models when you step on the throttle. Official figures show a 0-100 km/h acceleration time of just over 8 seconds. BMW deliberately tuned the 520 to a lower power output, offering 30+ fewer horsepower than the 525, making it more fuel-efficient for daily commutes, with highway consumption around 7L/100km. However, if you frequently drive mountain roads or enjoy strong acceleration, it's recommended to stretch the budget for the 530—its 248 horsepower delivers a much more spirited drive.

As someone who has driven three generations of the BMW 520, let me share some insights: The F10 model from a decade ago used a naturally aspirated 177 horsepower engine. In 2017, it was upgraded to a 184 horsepower B48 turbocharged engine, which continues to be used in the current G30 model. Although the horsepower figures haven't changed much, the new engine has optimized intake and exhaust systems, offering a broader torque plateau, delivering 290 Nm at just 2000 rpm. This tuning is very friendly for business use, ensuring smooth acceleration when picking up clients, and the chassis damping is also tailored for comfort. Compared to the Mercedes E200's 197 horsepower in the same class, the numbers are slightly lower, but the actual handling feels more responsive, thanks to BMW's renowned chassis tuning expertise.

According to the BMW technical manual, the 520 series is equipped with the B48B20 2.0T engine, delivering a maximum output of 184 horsepower at 5000 rpm and 290 Nm at 1350 rpm. It utilizes twin-scroll turbo technology to avoid cylinder interference and features an electronically controlled wastegate for more precise boost control. The transmission is a ZF 8-speed automatic, offering approximately 15% higher efficiency compared to CVT transmissions. This powertrain is sufficient for daily commuting, but for better performance, it's recommended to opt for the xDrive all-wheel-drive version, which significantly improves traction in rainy conditions. During maintenance, remember to replace the spark plugs every 40,000 kilometers to prevent power loss caused by ignition coil failures.
