"We’ve combined the best attributes of conventional automatic, continuously variable and dual clutch transmissions. The transmission locks up to couple directly with the engine over a far wider range than other automatics. This delivers a significant improvement in fuel economy and a more direct, manual-like power delivery and driving feel. Shifts are quick, accurate and smooth across the six speeds."

So, as they mention, this transmission is unique. It does, however, not lock up in all conditions - it remains unlocked until you hit 8mph. It sounds like an interesting transmission, but this is not the "norm". All conventional automatic transmissions should be able to do this, although it results in very different wear patterns (brake rings and clutches in the transmission will see much greater wear). It is not quite as interesting as a dual shift transmission, though.

(Having looked at a picture of the transmission, ignore the "combined the best attributes of..." - it appears to be an entirely conventional automatic transmission with a very different operating profile.)

I also drive a CX-5. When I test drove it, one of the things that stood out to me was how it felt "heavy" when taking your foot off the gas. I guess that was just the engine breaking that I wasn't used to on my previous vehicle. Over the last year I've averaged 30-31mpg (mostly highway), which I don't consider too bad for an AWD compact SUV.
