We’d better keep calm, but we need to know that an aftermarket garage in Illinois claims that the production capacity of the new BMW M4 is much higher than the announced figures! Some tests have suggested that the new M4 produces up to 465 horsepower. On the other hand, BMW itself has said that the production power of the standard version of this car is 475 hp.
So far, so good. But assuming a 15 percent drop in propulsion power, and in an unscientific but plausible estimate, Dino tests performed by that garage show that the M4 has up to 547 horsepower!
That means 74 horsepower more than the number announced by BMW! But wait. These results should not be trusted too much. First, as automotive engineers once explained in 2017, comparing numbers on different dynamometers at different locations is often inaccurate. In fact, the real use of these tools is to compare figures in a fixed location over and over again.
Humidity, altitude and many other parameters can affect the final result. Of course, we do not know where BMW is testing the power of its vehicles. But at least we know that the company’s engines are made in Munich. A city 520 meters above sea level, while the garage is located in Illinois, in an area with a maximum height of 208 meters above sea level!
Of course, some experts say that the power loss of modern cars is not as much as 15 percent, but only 10 percent. However, the numbers obtained from the Dino Garage test are not surprising. Because these numbers are a function of many parameters.
However, none of the effective factors such as humidity, altitude and difference in propulsion efficiency at different times can justify the difference of 74 hp. However, this could be good news for M4 owners, as if it were true, they would have delivered one of BMW’s most powerful cars.
