  11.  @pistonburner6448  It's true purpose? You mean a narrowed down window of operation to track and good quality roads with no heavy load? That's fine, roads have hugely improved the past decades outside Belgium, but it seems to me the true purpose of a suspension system is to keep the tyres following the surface in accordance with the driver's steering and pedal input. Within that there are specilizations, like cornering fast on a smooth surface, or the ability to both be comfortable and handle very rough surfaces, like the Range Rover. Please automakers, be true to your chosen purpose, your window you narrowed down to excell within, be the most BMW you can be, I appreciate that, not BMW building SUV's. I don't believe BMW should have switched to hydropneumatic suspension ever in history. It's not the party trick that made the hydropneumatic system superior, that was just something that came with concept, which had both the progressive nature of the suspension and the self levelling nature. That simply made for less trade off between road holding and stability vs comfort. I think Mercedes was able to tune a suspension and innovate on geometry too, and you see the result when Germans test it against a far more comfortable Citroen in the video abover. Mercedes btw that copied the Citroen system for it's top model above and almost twice expensive as the regular top model, the 450 SEL 6.9, often called the best car in the world, a chauffeur's limo and a driver's car in one. Air suspension never matched hydropneumatic suspension, or came close, Mercedes did a good job on the 600 and 300 SEL 6.3, but switched to the superior system for their newest top car. Mercedes and Citroen engineers were very much alike, they are innovative, stubborn and know what's best. What we see now is after decades of allmost all automotive engineers working to improve coil springs and almost non on the hydropneumatic, coil springs have massively improved. Dampers being electronically controlled, magnet powered, using gas properties like a hydropneumatic system, whatever, I'm not into the details I just know that there is a lot great engineering involved. What we have here is a competition between an excellent concept that worked great from the start because it was brilliant and simple, and we have lots of great engineers tinkering with a concept that started as an improvement on the leaf spring, according to most except Chevrolet. A break even point, a tipping point, was never unexpected in those circumstances and I believe it's behind us by now. But certainly not around 1990, the hydropneumatic suspension made the BX 1.9 perform in the mountains like cars much sportier or powerful and expensive.
