"Why would you call it outdated technology ?"

Because it's over 30 years old and there's some newer advanced technology
called DCD.

"There aren't or weren't many cars with this feature - certainly not in its displacement range."

This might be true in Europe. But in US, it started in 1980 from GM. Nowadays
there are at least 20 to 30 products by GM and Chrysler, most of them belong
to V8 products. Did any of them claim some significant fuel savings? NO! AND
WHY? Most of time the nice function is OFF, NOT USEFUL. Hope VW's
4-cylinder solution will fall into such case due to even less engine power. The
benefit of VW's new product may not come to the user, but come to promote
its product sales and stock price.

So if you really like this "new" technology, why not buy one and try it? and let
all of us know your test result. Before you spend some $16,000 to try it, or spend an EXTRA (I missed this last time!) $2000 to trade-in, you may wish to
try DCD with only $500 to retrofit your existing vehicle, with more effective
result. From its first day, DCD works on 4-cylinder engine.
