The BMW 4 Series Coupe M440i tests its speed limiter on the highway



[ad_1]

Even though the M440i is not a full M model, it still has a lot to offer. Look past its controversially-designed grille and you’ll find an inline-six engine as seen by its big brother, albeit with only one turbo and much less oomph. 369 horsepower (382 horsepower in the US) is no reason to sneeze, and the same could be said of torque – at 500 Newton-meters (369 pound-feet).

A new video from AutoTopNL shows what those output numbers mean in terms of actual performance, at least when it comes to accelerating in a straight line. The new M Performance version of the revamped 4 Series Coupe was put to the test on an unlimited section of the glorious German Autobahn. In other words, no speed laws were broken in the making of this video.

BMW can tell that the new M440i coupe does 0-100 km / h in four and a half seconds, but it seems a little faster. It wouldn’t really come as a surprise, as German manufacturers are known to be too careful with performance and tend to say their cars are slower than they actually are. The M Performance 4 Series Coupe didn’t take too long to activate the electronic top speed limiter.

While the M440i is listed as having a top speed of 155 mph (250 km / h), the digital speedometer shows that the car is doing 162 mph (261 km / h) at any given time. How was this possible? Modern speedometers show a speed slightly higher than the actual speed, especially as the car reaches higher speeds.

This setting represents how an automobile manufacturer ensures that the vehicle never reads below its actual speed. It is necessary to ensure that even after changing the diameter of a wheel and a tire, which ultimately impacts the speed of a car, the speedometer never underestimates the actual speed of the vehicle. . In other words, it is a margin of error allowing automakers to be cautious and never display the vehicle speed lower than the actual speed.

The sound you hear isn’t half bad, but we have to warn you that it is artificially enhanced when the M440i xDrive is in Sport mode. In other words, some of the noise is channeled through the audio speakers rather than coming exclusively from the 3.0-liter engine. BMW says it “provides an authentic reproduction of the engine note”, but that is still not entirely true.
