I’m going to fly in the face of everyone else in the world, VW engineers included, and say no, you do not *need* DCC.
Everyone else who is anybody as far as expert authority goes will disagree with me but that’s my uneducated take on it.
I would trust Exonian on this rather than the engineers.
There was a good piece on handling in June 2019 Evo (no 261) in which several top engineers were interviewed. One of the questions was " what do you think will be the next big thing in chassis development". Almost all of them talked about active suspension systems- and all seemed enthusiastic about it.
I think they're being a bit lazy. I want them to set the car up properly for the brief that's given for that car.
I want a practical car that's comfortable and fun to drive on a public road. Once the suspension is set up for that, it doesn't need to be changed. I'm never driving on an absolutely smooth racing track. Neither am I ever driving on really terrible roads. Nor do I expect- or even want- it to drive like a limo.
I think also that some of this is driven by marketing. People want stuff to mess with. It's why " graphic equalizers" were popular on low end 80s hifi. Have you seen how few buttons you get on quality hifi?
I'm fairly sure that if I specced a car with dcc, I'd work out which setting is best-for the use that I make of the car- and just leave it at that for my entire ownership.
Just like I have for the steering, throttle, and Dynaudio settings.
If the engineers set it up properly in the first place- assuming you're not intending to use the car on track- you don't need the cost and complexity of an active system.
I'm not interested in graphic equalizers!
