Hello dear viewers!
A different video from us than usual, please read the following text.
To start off we would like to say that APEX Auto Magazine conducts investigative journalism whereby the tests are done with professional and calibrated equipment. These tests are performed by highly educated professionals with years of technical experience. What also must be said is that all of the cars viewed in this video were made available by BMW Nederland, the importer for the Netherlands, so no cars from a dealership or otherwise.
The footage in these videos show that there are significant differences and problems with the brakes of different models from BMW.
APEX Auto Magazine is publishing this video in the common interest of the consumers that buy these cars. After conducting the brake test of the BMW 330e PHEV a while back we discovered serious shortcomings that resulted in brakes that got white-hot and eventually caught fire. Brakes that turn red are very hot and are acceptable with these tests, but white-hot means that their temperature lies well above 800 degrees Celsius and self-ignition occurs with due consequences.
APEX Auto Magazine introduced the braking test some years ago to show that braking with a (fast) car is of equal importance or perhaps more important than accelerating. Where most car media aim purely at acceleration times: 0-100 km/h, 0-200 km/h etc. But a car that drives this fast must also be capable of braking hard without any problems. And that is the reason why we do these tests. The braking tests we do are done with cars that drive 200 km/h or faster and not just only BMWs, but also models of other brands with fast cars.
Braking is done with maximal force (with reflex-action and around 100 kg pedal pressure) with the car at a speed of in between 200 and 275 km/h whereby full use is made of ABS, brake force assistance, stability systems and other assistance systems that are used in an emergency brake situation.
The measurement in another BMW (540i) also revealed a braking force of up to 1.4g which is 0.2g to 0.3g higher than is usually the case.
The M4 CS even became very unstable during the braking tests. At a speed of 220 km/h the car started to swerve making counter-steering necessary which you can see clearly in the footage. This indicates uneven braking force per brake-unit and we’re talking about carbon-ceramic brakes here!
APEX Auto Magazine at that time tried to start a conversation with BMW Nederland, but after we showed the brakes catching fire on the BMW 330e PHEV the reaction of the Product Communications Manager of BMW Nederland was in our eyes quite stoic and reserved, the person in question put the problem in our hands which is of course not realistic. What also was said was that one can never drive that fast in the Netherlands, which is of course nonsense, just cross the border with Germany and you can drive as fast as you like. In short: the blame was on us. How the internal communication within BMW Nederland has been about this problem is not known to us. But what was indeed ‘urgently’ asked of us was to change the way that we do these tests, but of course we didn’t comply with that request.
Sadly, we don’t get any feedback by BMW Nederland about this problem.
Thus far our report about this subject.
